NEW QUESTION # 232
A voice packet requires a latency of 50 msec. Which policy is configured to ensure that a voice packet is always sent on the link with less than a 50 msec delay?

A. centralized data
B. centralized control
C. localized data
D. localized control

Answer: A

Explanation:
Centralized data policy: policy that is configured on a Cisco vSmart Controller (hence, it is centralized) and that affects data traffic being transmitted between the routers on the Cisco SD-WAN overlay network. They affect traffic flow across the entire network. This will also help in controlling to send specific application traffic over specific tunnel based on jitter, delay, latency.

What is the advantage of instating the controller on-premises?

A. scalability and a cost-saving
B. full control of the data piano and the control plane
C. ease of deployment and management
D. automatic geographical redundancy and security

Answer: B

Explanation:
Deploying the SD-WAN controller on-premises offers several advantages, particularly in terms of control and customization.
* Full Control of the Data Plane and the Control Plane: When the controller is deployed on-premises, the organization maintains complete control over both the data plane (traffic forwarding) and the control plane (network management and configuration). This allows for more granular control over network policies, security configurations, and performance optimizations.
* Customization and Security: On-premises deployment allows organizations to customize their SD-WAN setup to meet specific security and compliance requirements. Sensitive data remains within the organization's control, which can be crucial for industries with strict data privacy regulations.
* Operational Flexibility: Having the controller on-premises provides operational flexibility, enabling organizations to integrate the SD-WAN solution with existing network management tools and processes.
