• A. IP VPN
• B. EVPN Type 2 stretch
• C. over the top full-mesh interconnect
• D. Type 2 seamless stitching

Answer: D

Explanation:
* Requirement Analysis:
* The scenario requires a solution to interconnect two data centers that supports EVPN Type 2 connectivity. The solution must be highly scalable and must minimize the number of VXLAN tunnels between border leaf devices.
* Understanding Type 2 Seamless Stitching:
* Option D:Type 2 seamless stitchingis a method used in EVPN to provide Layer 2 connectivity (such as MAC address mobility) across different VXLAN segments. It is scalable because it allows only necessary tunnels to be established between border leaf devices, reducing the overhead of maintaining a full mesh of VXLAN tunnels.
Conclusion:
* Option D:Correct-Type 2 seamless stitching satisfies the requirement by enabling scalable, efficient interconnection of two data centers with minimal VXLAN tunnels.

NEW QUESTION # 36
You are implementing VXLAN broadcast domains in your data center environment. Which two statements are correct in this scenario? (Choose two.)

• A. The VNI must match the VLAN tag to ensure that the remote VTEP can decapsulate VXLAN packets.
• B. Layer 2 frames are encapsulated by the source VTEP.
• C. The VNI is a 16-bit value and can range from 0 through 16.777.215.
• D. A VXLAN packet does not contain a VLAN ID.

Answer: B,D

Explanation:
* VXLAN Overview:
* VXLAN (Virtual Extensible LAN) is a network virtualization technology that encapsulates Layer
2 Ethernet frames into Layer 3 UDP packets for transmission over an IP network. It allows the creation of Layer 2 overlay networks across a Layer 3 infrastructure.
* Understanding VXLAN Components:
* VTEP (VXLAN Tunnel Endpoint):A VTEP is responsible for encapsulating and decapsulating Ethernet frames into and from VXLAN packets.
* VNI (VXLAN Network Identifier):A 24-bit identifier used to distinguish different VXLAN segments, allowing for up to 16 million unique segments.
* Correct Statements:
* C. Layer 2 frames are encapsulated by the source VTEP:This is correct. In a VXLAN deployment, the source VTEP encapsulates the original Layer 2 Ethernet frame into a VXLAN packet before transmitting it over the IP network to the destination VTEP, which then decapsulates it.
* A. A VXLAN packet does not contain a VLAN ID:This is correct. The VXLAN header does not carry the original VLAN ID; instead, it uses the VNI to identify the network segment. The VLAN ID is local to the switch and does not traverse the VXLAN tunnel.
* Incorrect Statements:
* B. The VNI must match the VLAN tag to ensure that the remote VTEP can decapsulate VXLAN packets:This is incorrect. The VNI is independent of the VLAN tag, and the VLAN ID does not need to match the VNI. The VNI is what the remote VTEP uses to identify the correct VXLAN segment.
* D. The VNI is a 16-bit value and can range from 0 through 16,777,215:This is incorrect because the VNI is a 24-bit value, allowing for a range of 0 to 16,777,215.
Data Center References:
* VXLAN technology is critical for modern data centers as it enables scalability and efficient segmentation without the constraints of traditional VLAN limits.

NEW QUESTION # 37
Which two statements are true about a pure IP fabric? (Choose two.)

• A. An IP fabric supports Layer 2 VLANs.
• B. An IP fabric does not support Layer 2 protocols.
• C. Devices in an IP fabric must be connected to a fabric controller.
• D. Devices in an IP fabric function as Layer 3 routers.

Answer: B,D

Explanation:
* Understanding Pure IP Fabric:
* A pure IP fabric is a network design where all devices operate at Layer 3, meaning that each device in the fabric is a router that makes forwarding decisions based on IP addresses.
* Layer 2 Support:
* In a pure IP fabric, traditional Layer 2 protocols such as Spanning Tree Protocol (STP) or VLANs are not supported. Instead, the network relies entirely on Layer 3 routing protocols to manage traffic between devices.
* Routing Functionality:
* Since devices in an IP fabric operate as Layer 3 routers, they handle IP routing and provide network services based on IP addresses, not on MAC addresses or Layer 2 switching.
Conclusion:
* Option A:Correct-Devices in an IP fabric function as Layer 3 routers.
* Option D:Correct-A pure IP fabric does not support traditional Layer 2 protocols, making it a purely routed environment.

NEW QUESTION # 38
A local VTEP has two ECMP paths to a remote VTEP
Which two statements are correctwhen load balancing is enabled in this scenario? (Choose two.)

• A. The destination port in the UDP header is used to load balance VXLAN traffic.
• B. The inner packet fields are used in the hash for load balancing.
• C. The source port in the UDP header is used to load balance VXLAN traffic.
• D. The inner packet fields are not used in the hash for load balancing.

Answer: B,C

Explanation:
* Load Balancing in VXLAN:
* VXLAN uses UDP encapsulation to transport Layer 2 frames over an IP network. For load balancing across Equal-Cost Multi-Path (ECMP) links, various fields in the packet can be used to ensure even distribution of traffic.
* Key Load Balancing Fields:
* C. The source port in the UDP header is used to load balance VXLAN traffic:This is correct.
The source UDP port in the VXLAN packet is typically calculated based on a hash of the inner packet's fields. This makes the source port vary between packets, enabling effective load balancing across multiple paths.
* D. The inner packet fields are used in the hash for load balancing:This is also correct. Fields such as the source and destination IP addresses, source and destination MACaddresses, and possibly even higher-layer protocol information from the inner packet can be used to generate the hash that determines the ECMP path.
* Incorrect Statements:
* A. The inner packet fields are not used in the hash for load balancing:This is incorrect as the inner packet fields are indeed critical for generating the hash used in load balancing.
* B. The destination port in the UDP header is used to load balance VXLAN traffic:This is incorrect because the destination UDP port in VXLAN packets is typically fixed (e.g., port 4789 for VXLAN), and therefore cannot be used for effective load balancing.
Data Center References:
* Effective load balancing in VXLAN is crucial for ensuring high throughput and avoiding congestion on specific links. By using a combination of the source UDP port and inner packet fields, the network can distribute traffic evenly across available paths.

NEW QUESTION # 39
You want to convert an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway for VNI 100. You have already configured an IRB interface. In this scenario, which command would you use to accomplish this task?

• A. set vlans VLAN-100 13-interface irb.100
• B. set bridge-domains VLAN-100 routing-interface irb.100
• C. set protocols isis interface irb.100 passive
• D. set protocols ospf area 0.0.0.0 interface irb.100 passive

Answer: B

Explanation:
* Scenario Overview:
* Converting an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway involves transitioning the router's functionality from simply bridging traffic within a VXLAN segment to routing traffic between different segments.
* Key Configuration Requirement:
* IRB (Integrated Routing and Bridging) Interface:An IRB interface allows for both Layer 2 switching and Layer 3 routing. To enable routing for a specific VNI (VXLAN Network Identifier), the IRB interface must be associated with the routing function in the corresponding bridge domain.
* Correct Command:
* C. set bridge-domains VLAN-100 routing-interface irb.100:This command correctly binds the IRB interface to the bridge domain, enabling Layer 3 routing functionality within the VXLAN for VNI 100. This effectively transitions the device from operating solely as a Layer 2 gateway to a Layer 3 gateway.
Data Center References:
* This configuration step is essential when converting a Layer 2 VXLAN gateway to a Layer 3 gateway, enabling the MX Series router to route between VXLAN segments.

NEW QUESTION # 40
Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

• A. Symmetric routing is less efficient than asymmetric routing.
• B. Symmetric routing requires MAC-VRF.
• C. Symmetric routing requires an extra transit VNI for each VRF.
• D. An L3 interface (IRB) is required for each local VLAN.
• E. Symmetric routing supports the EVPN service VLAN bundle.

Answer: B,C,D

Explanation:
* Symmetric IRB Routing with EVPN Type 2 Routes:
* Symmetric Routing: In symmetric IRB (Integrated Routing and Bridging), routing occurs in both directions at the ingress and egress leaf nodes using the same routing logic. This is contrasted with asymmetric routing, where different routing logic is used depending on the direction of the traffic.
* Required Components:
* Option A:An L3 IRB interface is necessary for each VLAN that participates in routing, as it handles the Layer 3 processing for the VLAN.
* Option B:MAC-VRF is required for symmetric routing to maintain a mapping of MAC addresses to the appropriate VRF, ensuring correct forwarding within the EVPN.
* Option D:A transit VNI (Virtual Network Identifier) is required for each VRF to encapsulate the Layer 3 traffic as it traverses the network, allowing the IP traffic to be appropriately forwarded.
Conclusion:
* Option A:Correct-Each local VLAN needs an IRB interface for L3 processing.
* Option B:Correct-MAC-VRF is necessary for handling MAC address resolution in symmetric routing.
* Option D:Correct-Transit VNIs are required for routing VRF-specific traffic across the network.
OptionsCandEare incorrect because:
* C:Symmetric routing can work with various VLAN models, including single or multiple VLANs within an EVPN instance.
* E:Symmetric routing is generally more efficient than asymmetric routing as it uses consistent routing logic in both directions.

NEW QUESTION # 41
You are deploying a Clos IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)

• A. The oversubscription ratio increases when you remove spine devices.
• B. The oversubscription ratio remains the same when you remove spine devices.
• C. The oversubscription ratio remains the same when you add spine devices.
• D. The oversubscription ratio decreases when you add spine devices.

Answer: A,D

Explanation:
* Understanding Oversubscription in a Clos Fabric:
* The oversubscription ratio in a Clos IP fabric measures the ratio of the amount of edge (leaf) bandwidth to the core (spine) bandwidth. An oversubscription ratio of 3:1 means that there is three times more edge bandwidth compared to core bandwidth.
* Impact of Adding/Removing Spine Devices:
* Option C:If youremove spine devices, the total available core bandwidth decreases, while the edge bandwidth remains the same. This results in anincrease in the oversubscription ratio because there is now less core bandwidth to handle the same amount of edge traffic.
* Option B:Conversely, if youadd spine devices, the total core bandwidth increases. This decreases the oversubscription ratio because more core bandwidth is available to handle the edge traffic.
Conclusion:
* Option C:Correct-Removing spine devices increases the oversubscription ratio.
* Option B:Correct-Adding spine devices decreases the oversubscription ratio.

NEW QUESTION # 42
Exhibit.

Referring tothe exhibit, which statement is correct?

• A. The remote VTEP is not responding.
• B. The MAC address is known but not reachable by the remote VTEP
• C. VNI 100 is not configured on the remote VTEP.
• D. The MAC address is unknown and not in the forwarding table of the remote VTEP.

Answer: D

Explanation:
* Analyzing the Exhibit Output:
* The command ping overlay tunnel-type vxlan is used to test the VXLAN tunnel between two VTEPs (VXLAN Tunnel Endpoints). The output shows a warning about missing hash parameters, but more importantly, it displays the result: End-System Not Present.
* Understanding the Response:
* The message End-System Not Present indicates that the remote VTEP (192.168.2.20) did not find the MAC address 00:00:5E:00:53:CC in its forwarding table. This typically means that the MAC address is unknown to the remote VTEP, and as a result, it could not forward the packet to the intended destination.
Conclusion:
* Option B:Correct-The MAC address is unknown and is not in the forwarding table of the remote VTEP, which is why the system reports that the "End-System" is not present.

• A. VXLAN GBP ensures consistent application of BGP groups throughout the network.
• B. VXLAN GBP uses scalable group tags that may be configured on a RADIUS server and pushed to the switch through 802.1X.
• C. VXLAN GBP ensures consistent application of security group policies throughout the network.
• D. VXLAN GBP uses scalable group tags thatmust be configured statically on each switch and activated through 802.1X.

Answer: B,C

Explanation:
* VXLAN Group-Based Policies (GBP):
* VXLAN Group-Based Policies are used to apply security policies consistently across the network. These policies are often tied to user or device identities rather than static IP addresses, which allows for more dynamic and scalable security management.
* Scalable Group Tags via RADIUS and 802.1X:
* Option B:VXLAN GBP can use scalable group tags configured on a RADIUS server, which are then pushed to network devices through 802.1X. This allows for centralized and automated policy application based on user or device identity.
* Consistent Security Policy Application:
* Option C:GBP ensures that security policies are consistently applied across the network, regardless of where a user or device connects. This consistency is crucial in environments where security policies must follow the user or device.
Conclusion:
* Option B:Correct-Group tags can be configured on a RADIUS server and pushed via 802.1X, enabling centralized policy management.
* Option C:Correct-GBP ensures consistent application of security policies, which is essential for maintaining security across a dynamic network environment.

Which statement is correct about a collapsed fabric EVPN-VXLAN architecture?

• A. Fully meshed back-to-back links are needed between the spine devices.
• B. It supports multiple vendors in the fabric as long as all the spine devices are Juniper devices deployed with L2 VTEPs
• C. Using Virtual Chassis at the leaf layer increases resiliency.
• D. Border gateway functions occur on border leaf devices.

Answer: D

Explanation:
* Collapsed Fabric Architecture:
* A collapsed fabric refers to a simplified architecture where the spine and leaf roles are combined, often reducing the number of devices and links required.
* In this architecture, the spine typically handles core switching, while leaf switches handle both access and distribution roles.
* Understanding Border Gateway Functionality:
* Border gateway functions include connecting the data center to external networks or other data centers.
* In a collapsed fabric, these functions are usually handled at the leaf level, particularly on border leaf devices that manage the ingress and egress of traffic to and from the data center fabric.
* Correct Statement:
* D. Border gateway functions occur on border leaf devices:This is accurate in collapsed fabric architectures, where the border leaf devices take on the role of managing external connections and handling routes to other data centers or the internet.
Data Center References:
* The collapsed fabric model is advantageous in smaller deployments or scenarios where simplicity and cost-effectiveness are prioritized. It reduces complexity by consolidating functions into fewer devices, and the border leaf handles the critical task of interfacing with external networks.
In conclusion, border gateway functions are effectively managed at the leaf layer in collapsed fabric architectures, ensuring that the data center can communicate with external networks seamlessly.

NEW QUESTION # 45
Exhibit.

You are troubleshooting an IP fabric (or your data center. You notice that your traffic is not being load balanced to your spine devices from your leaf devices. Referring to the configuration shown in the exhibit, what must be configured to solve this issue?

• A. The load-balance policy must be applied as an export policy to your BGP
• B. The load-balance policy must have a from statement that matches on protocol bgp.
• C. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.
• D. The multipastmultiple -as configuration must be configured for each peer in the BGP spine group.

Answer: D

Explanation:
* IP Fabric Load Balancing:
* In the provided configuration, traffic is not being load-balanced to the spine devices. The issue likely relates to how BGP routes are being selected and whether Equal-Cost Multi-Path (ECMP) is functioning correctly.
* Multipath Multiple-AS:
* Option B:The multipath multiple-as configuration is essential when using BGP in an IP fabric where devices belong to different Autonomous Systems (AS). This setting allows BGP to consider multiple paths (even across different AS numbers) as equal cost, enabling ECMP and proper load balancing across spine devices.
Conclusion:
* Option B:Correct-The multipath multiple-as configuration is necessary for achieving ECMP and effective load balancing in a multi-AS BGP environment.

NEW QUESTION # 46

NEW QUESTION # 47
You are asked to build redundant gateways in your EVPN-VXLAN environment, but you must conserve address space because these gateways must span across seven PES. What should you implement on the PEs lo satisfy these requirements?

• A. Use IRB interfaces with the same IP and MAC address.
• B. Use IRB interfaces with the same IP and VGA.
• C. Use IRB interfaces with different IP addresses and the same VGA.
• D. Use IRB interfaces with the same IP address and different MAC addresses.

Answer: A

Explanation:
* Redundant Gateways in EVPN-VXLAN:
* In an EVPN-VXLAN environment, providing redundant gateway functionality typically involves the use of Anycast Gateway. This allows multiple PEs (Provider Edge devices) to use the same IP address and MAC address for the gateway, enabling seamless failover and redundancy without IP conflicts.
* Conserving Address Space:
* Using the same IP address across multiple PEs conserves address space because only one IP address is needed for the gateway function, regardless of the number of PEs. The shared MAC address ensures that ARP resolution and forwarding behavior are consistent across all the PEs.
Conclusion:
* Option C:Correct-Using IRB interfaces with the same IP and MAC address across all PEs satisfies the need for redundancy while conserving address space.
OptionsA, B,andDintroduce unnecessary complexity or do not fully utilize the efficient Anycast Gateway approach, which is best practice for conserving IP space and providing redundancy.

NEW QUESTION # 48
Exhibit.

You are troubleshooting a DCI connection to another data center The BGP session to the provider is established, but the session to Border-Leaf-2 is not established. Referring to the exhibit, which configuration change should be made to solve the problem?

• A. set protocols bgp group overlay export loopbacks
• B. delete protocols bgp group OVERLAY accept-remote-nexthop
• C. delete protocols bgp group UNDERLAY advertise-external
• D. set protocols bgp group PROVIDER export LOOPBACKS

Answer: B

Explanation:
* Understanding the Configuration:
* The exhibit shows a BGP configuration on a Border-Leaf device. The BGP group UNDERLAY is used for the underlay network, OVERLAY for EVPN signaling, and PROVIDER for connecting to the provider network.
* The OVERLAY group has the accept-remote-nexthop statement, which is designed to accept the next-hop address learned from the remote peer as is, without modifying it.
* Problem Identification:
* The BGP session to Border-Leaf-2 is not established. A common issue in EVPN-VXLAN environments is related to next-hop reachability, especially when accept-remote-nexthop is configured.
* In typical EVPN-VXLAN setups, the next-hop address should be reachable within the overlay network. However, the accept-remote-nexthop can cause issues if the next-hop IP address is not directly reachable or conflicts with the expected behavior in the overlay.
* Corrective Action:
* D. delete protocols bgp group OVERLAY accept-remote-nexthop:Removing this command will ensure that the device uses its own IP address as the next-hop in BGP advertisements, which is standard practice in many EVPN-VXLAN setups. This change should help establish the BGP session with Border-Leaf-2.
Data Center References:
* Proper handling of BGP next-hop attributes is critical in establishing and maintaining stable BGP sessions, especially in complex multi-fabric environments like EVPN-VXLAN. Removing accept- remote-nexthop aligns with best practices in many scenarios.

Answer: B,D

Explanation:
* Understanding the Output:
* The show evpn database command output shows the MAC address, VLAN, active source, timestamp, and IP address associated with various hosts in the EVPN instance.
* Analysis of the MAC Address:
* Option A:The MAC address 40:00:dc:01:00:04 is associated with the IP address 10.4.4.5, as indicated by the output in the IP address column. This confirms that this host has been assigned the IP 10.4.4.5.
* Option D:The active source for the MAC address 40:00:dc:01:00:04 is listed as 00:02:00:00:00:
04:00:04:00:00:04:00:04, which indicates that the host is connected via an ESI (Ethernet Segment Identifier) LAG (Link Aggregation Group). This setup is typicallyused in multi-homing scenarios to provide redundancy and load balancing across multiple physical links.
Conclusion:
* Option A:Correct-The host with MAC 40:00:dc:01:00:04 is assigned IP 10.4.4.5.
* Option D:Correct-The host is originating from an ESI LAG, as indicated by the active source value.

NEW QUESTION # 50
In your EVPN-VXAN environment, you want to prevent a multihomed server from receiving multiple copies ofBUM traffic in active/active scenarios. Which EVPN route type would satisfy this requirement?

• A. Type 7
• B. Type 4
• C. Type 5
• D. Type 8

Answer: B

Explanation:
* Understanding the Scenario:
* In an EVPN-VXLAN environment, when using multi-homing in active/active scenarios, there's a risk that a multihomed server might receive duplicate copies of Broadcast, Unknown unicast, and Multicast (BUM) traffic. This is because multiple VTEPs might forward the same BUM traffic to the server.
* EVPN Route Types:
* Type 4 Route (Ethernet Segment Route):This route type is used to advertise the Ethernet Segment (ES) to which the device is connected. It is specifically used in multi-homing scenarios to signal the ES and its associated Ethernet Tag to all the remote VTEPs. The Type 4 route includes information that helps prevent BUM traffic duplication in active/active multi-homing by using a split-horizon mechanism, which ensures that traffic sent to a multihomed device does not get looped back.
* Explanation:
* The Type 4 route is crucial for ensuring that in a multi-homed setup, particularly in an active
/active configuration, BUM traffic does not result in duplication at the server. The route helps coordinate which VTEP is responsible for forwarding the BUM traffic to the server, thereby preventing duplicate traffic.
Data Center References:
* Type 4 routes are essential for managing multi-homing in EVPN to avoid the issues of BUM traffic duplication, which could otherwise lead to inefficiencies and potential network issues.

NEW QUESTION # 51
You are asked to identify microburst traffic occurring in the network leading lo packet drops in your data center switches Which two tools would be used in this scenario? (Choose two.)

• A. port buffer monitoring
• B. port mirroring
• C. syslog
• D. Traceoptions

Answer: A,B

Explanation:
* Identifying Microburst Traffic:
* Microbursts are short spikes in network traffic that can overwhelm buffers and cause packet drops. Detecting and analyzing microbursts is crucial for understanding where packet loss might be occurring in a data center network.
* Port Buffer Monitoring:
* Port Buffer Monitoring:This tool specifically tracks the usage of switch buffers, helping to identify when microbursts are causing buffers to overflow, leading to packet drops.
* Port Mirroring:
* Port Mirroring:This tool allows you to monitor real-time traffic on a specific port by copying the traffic to another port where it can be analyzed, often with a packet analyzer. While port mirroring doesn't directly detect microbursts, it helps capture traffic patterns that can indicate microbursts.
Conclusion:
* Option C:Correct-Port buffer monitoring directly identifies buffer overflows caused by microbursts.
* Option A:Correct-Port mirroring allows for the detailed capture and analysis of traffic patterns, which can reveal microburst behavior.
Options B(Traceoptions) andD(Syslog) are less effective in identifying microburst traffic. Traceoptions focus on control plane traffic debugging, and Syslog is more about logging system events than detecting high- frequency traffic spikes.
