NEW QUESTION # 42
A vSphere cluster has the following configuration:
* Virtual machines (VMs) are running Production and Test workloads
* vSphere Distributed Resource Scheduler (DRS) is enabled
* There are no resource pools in the cluster
Performance monitoring data shows that the Production workload VMs are not receiving their fully allocated memory when the vSphere cluster is fully utilized.
A combination of which two steps could the administrator perform to ensure that the Production VMs are always guaranteed the full allocation of memory? (Choose two.)
- A. Create a child resource pool for the Test VMs.
- B. Create a sibling resource pool for each of the Production and Test VMs.
- C. Assign a memory reservation value to the resource pool containing the Production VMs.
- D. Create a parent resource pool for the Production VMs.
- E. Assign a custom memory share value to the resource pool containing the Production VMs.
Answer: A,C
Explanation:
Explanation
Option B and E are correct because they allow the administrator to create resource pools for the Production and Test VMs and assign memory reservation values to the Production resource pool, which guarantees that the Production VMs are always allocated their full memory. Option A is incorrect because assigning a custom memory share value to the Production resource pool does not guarantee that the Production VMs are always allocated their full memory, but only gives them higher priority when there is contention. Option C is incorrect because creating a parent resource pool for the Production VMs does not change anything unless there are child resource pools under it. Option D is incorrect because creating a sibling resource pool for each of the Production and Test VMs does not change anything unless there are different resource settings for each pool.

NEW QUESTION # 45
A company has two sites: Site A and Site B. The administrator would like to manage the VMware vCenter inventories in both sites from a single vSphere Client session.
Which vCenter feature must be configured?
- A. VMware Site Recovery Manager
- B. vCenter Single Sign-On
- C. Enhanced Linked Mode
- D. VMware Certificate Authority
Answer: C
Explanation:
Explanation
Option D is correct because it indicates that Enhanced Linked Mode must be configured to allow the administrator to manage the VMware vCenter inventories in both sites from a single vSphere Client session.
Enhanced Linked Mode allows multiple vCenter Server instances to share information such as tags, licenses, roles, permissions, and policies. Option A is incorrect because VMware Certificate Authority is a service that provides certificates for vSphere components and does not affect inventory management. Option B is incorrect because VMware Site Recovery Manager is a solution that provides disaster recovery and business continuity for vSphere environments and does not affect inventory management. Option C is incorrect because vCenter Single Sign-On is a service that provides authentication and authorization for vSphere components and does not affect inventory management. References:

-virtualization-based security feature? (Choose three.)
- A. Hot Add of CPU or memory
- B. vSphere vMotion
- C. vSphere Distributed Resources Scheduler (DRS)
- D. PCI passthrough
- E. vSphere High Availability (HA)
D, vSphere Fault Tolerance
Answer: A,B,E
Explanation:
Explanation
Option A, C and E are correct because they indicate that vSphere features such as vMotion, High Availability (HA) and Distributed Resource Scheduler (DRS) are still supported for Windows-based virtual machines when enabling vSphere's virtualization-based security feature, which provides enhanced protection for guest operating systems and applications against various attacks. Option B is incorrect because PCI passthrough is not supported for Windows-based virtual machines when enabling vSphere's virtualization-based security feature, as this feature requires direct access to physical devices that cannot be shared or protected by hypervisor mechanisms. Option D is incorrect because Fault Tolerance is not supported for Windows-based virtual machines when enabling vSphere's virtualization-based security feature, as this feature requires identical execution states for primary and secondary virtual machines that cannot be guaranteed by hypervisor mechanisms. Option F is incorrect because Hot Add of CPU or memory is not supported for Windows-based virtual machines when enabling vSphere's virtualization-based security feature, as this feature requires dynamic changes to virtual hardware configuration that cannot be handled by hypervisor mechanisms.

An administrator plans to update the Supervisor cluster and has noticed some of the Tanzu Kubemetes Grid clusters are running an incompatible version.
Which action must the administrator take before proceeding with the Supervisor cluster update?
- A. Update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update.
- B. No action is needed - Incompatible Tanzu Kubernetes Grid clusters can be manually updated after the Supervisor cluster update.
- C. Update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update.
- D. No action is needed - Tanzu Kubernetes Grid clusters will be updated automatically as part of the update process.
Answer: C
Explanation:
Explanation
Option D is correct because it indicates that the administrator must update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update, as this will ensure that there are no compatibility issues or disruptions during or after the update process. Option A is incorrect because it is not necessary to update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update, as some clusters may already be compatible with the new version. Option B is incorrect because Tanzu Kubernetes Grid clusters will not be updated automatically as part of the update process, as they require manual intervention from the administrator. Option C is incorrect because incompatible Tanzu Kubernetes Grid clusters cannot be manually updated after the Supervisor cluster update, as they may become inaccessible or unstable due to compatibility issues.

NEW QUESTION # 49
An administrator notices a Fibre Channel adapter in an ESXi host has been experiencing inconsistent connectivity states Which trigger can be used to quickly identify the issue and alert the administrator so that the issue can be resolved?
- A. Lost Network Path Redundancy
- B. Host Connection Lost
- C. Lost Network Connectivity
- D. Lost Storage Connectivity
Answer: A
Explanation:
Complicated, the question does not comment on whether the path is redundant, if not redundant the correct answer would be D, but if we take into account good practices, the FC would be redundant.
https://kb.vmware.com/s/article/2014553
Book course: 6-23 Fibre Channel SAN Components Using SAN switches, you can set up path redundancy to address any path failures from host server to switch, or from storage array to switch. 6-25 Multipathing with Fibre Channel By default, ESXi hosts use only one path from a host to a given LUN at any one time. If the path actively being used by the ESXi host fails, the server selects another available path.
