2V0-621D Online Practice Questions and Answers

Correct Answer: B

Disable lockdown mode through the DCUI and then enable it through the vCenter Server instead. The vCenter Server does not keep track of lockdown mode state changes that initiated outside of the vCenter Server itself.

Correct Answer: A

Datastore.Allocate space allows allocating space on a datastore for a virtual machine, snapshot, clone, or virtual disk.

Correct Answer: AC

Using a machine account when configuring an Active Directory identity source for vCenter Server requires that the Windows system be joined to the domain. If the system is not joined to the domain, SSO cannot leverage the machine account

to create the identity source and perform its function as the secure token service user.

To resolve this issue in VCVA 5.5, use only the Use SPN option.

Correct Answer: AB

The vsphere.local domain includes several predefined groups. Assign users to one of those groups to be able to perform the corresponding actions.

For all objects in the vCenter Server hierarchy, permissions are assigned by pairing a user and a role with the object. For example, you can select a resource pool and give a group of users read privileges to that resource pool by giving them the corresponding role. For some services that are not managed by vCenter Server directly, privileges are determined by membership to one of the vCenter Single Sign-On groups. For example, a user who is a member of the Administrator group can manage

vCenter Single Sign-On. A user who is a member of the CAAdmins group can manage the VMware Certificate Authority, and a user who is in the LicenseService.Administrators group can manage licenses.

Correct Answer: A

If your Virtual SAN cluster spans across multiple racks or blade server chassis in a data center and you want to make sure that your hosts are protected against rack or chassis failure, you can create fault domains and add one or more hosts to it.

A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.

The number of failures your cluster can tolerate depends on the number of failures a virtual machine is provisioned to tolerate. For example, when a virtual machine is configured with Number of failures to tolerate=1 and using multiple fault domains, Virtual SAN can tolerate a single failure of any kind and of any component in a fault domain, including the failure of an entire rack. When you configure fault domains on a rack and provision a new virtual machine, Virtual SAN ensures that protection objects, such as replicas and witnesses are placed on different fault domains. If, for example, a virtual machine's storage policy is Number of failures to tolerate=n, Virtual SAN requires a minimum of 2*n+1 fault domains in the cluster. When virtual machines are provisioned in a cluster with fault domains using this policy, the copies of the associated virtual machine objects are stored across separate racks.

Correct Answer: A

Give No Access to the user at the vCenter Level. Go to the particular cluster you want to give permissions for. Then click on the permissions tab of that cluster and give the user Administrator access(or whatever role you intend to give). It will ask to override the inherited permissions, say Yes. Now when the user logs in, he/she will see only one cluster under the vCenter. No access will remove the visibility to the object
