An administrator is creating a content library to manage VM templates and ISO images. The administrator wants to password-protect the images and templates and share them with a remote site.
Which two tasks must the administration perform when creating the content library? (Choose two.)

1. A. Publish the local content library.
2. B. Enable the security policy.
3. C. Create a subscribed content library.
4. D. Select an NFS datastore.
5. E. Enable authentication.

Correct Answer: AE
To password-protect and share images and templates with a remote site, the administrator needs to publish the local content library, which makes it available for subscription by other vCenter Server instances; and enable authentication, which requires users to enter credentials when accessing the content library.

An administrator Is looking to deploy a new VMware vCenter Instance. The current environment consists of 75 hosts and is expected to grow up to 100 hosts over the next three years.
Which deployment size should the administrator select?

1. A. Medium
2. B. Tiny
3. C. Large
4. D. Small

Correct Answer: D
VMWare: Small environment (up to 100 hosts or 1,000 virtual machines) Medium environment (up to 400 hosts or 4,000 virtual machine)
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID-88571D8A-46E1-464 The administrator should select the small deployment size for the new vCenter Server instance, which is suitable for an environment with up to 100 hosts or 1,000 virtual machines. The small deployment size has 4 vCPUs and 19 GB of memory, which can handle the current and expected growth of the environment. The other deployment sizes are either too large or too small for the environment. References:

Which feature would allow for the non-disruptive migration of a virtual machine between two clusters in a single VMware vCenter instance?

1. A. vSphere vMotion
2. B. Cross vCenter Migration
3. C. vSphere Storage vMotion
4. D. vSphere Fault Tolerance

Correct Answer: A
vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance, as long as there is shared storage and network connectivity between the clusters.

https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vcenterhost.doc/GUID-3B41119A-127
vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don't you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.

An administrator receives reports from the application team of poor performance of a virtual ma-chine (VM). The administrator reviews the virtual machine and discovers that it has 20 snapshots that are over 12 months old.
What could the administrator do to improve the VM’s performance?

1. A. Inflate the base disk to make space for future snapshots.
2. B. Revert to the latest snapshot.
3. C. Consolidate all of the snapshots into the base VM.
4. D. Identify and delete the largest delta .vmdk file.

Correct Answer: C

An administrator is responsible for performing maintenance tasks on a vSphere cluster. The cluster has the following configuration:
. Identically configured vSphere ESXi hosts (esx01, esx02, esx03 and esx04)
• All workloads are deployed into a single VMFS datastore provided by the external storage array
• vSphere High Availability (HA) has not been enabled
• vSphere Distributed Resource Scheduler (DRS) has not been enabled Currently, a critical production application workload (VM1) is running on esx01.
Given this scenario, which two actions are required to ensure VM1 continues to run when esx01 is placed into maintenance mode? (Choose two.)

1. A. Fully automated DRS must be enabled on the cluster so that VM1 will be automatically migrated to another host within the cluster when esx01 is placed into maintenance mode.
2. B. VM1 must be manually shut down and cold migrated to another host within the cluster using vSphere vMotion before esx01 is placed into maintenance mode.
3. C. vSphere HA must be enabled on the cluster so that VM1 will be automatically migrated to another host within the cluster when esx01 is placed into maintenance mode.
4. D. VM1 must be manually live migrated to another host within the cluster using vSphere vMotion before esx01 is placed into maintenance mode.
5. E. VM1 must be manually migrated to another host within the cluster using vSphere Storage vMotion before esx01 is placed into maintenance mode.

Correct Answer: AD
Two actions that are required to ensure VM1 continues to run when esx01 is placed into maintenance mode are enabling fully automated DRS on the cluster, which allows balancing the workload across hosts and migrating VMs without user intervention; and manually live migrating VM1 to another host within the cluster using vSphere vMotion, which allows moving a running VM without downtime.
