NEW QUESTION 1
An administrator is in the process of deploying a new ESXi host.
-The host is able to be added to the vCenter Server’s inventory, but after a short period of time it shows as disconnected.
-The administrator is able to reconnect the host but it then disconnects again after a short period of time. Which is the problem?

• A. Port 902 UDP from the host to the vCenter Server is blocked
• B. Port 443 TCP from the host to the vCenter Server is blocked
• C. Port 902 TCP from the host to the vCenter Server is blocked
• D. Port 443 TCP from the vCenter Server to the host is blocked

Answer: A

Explanation: On 902 port managed hosts send a regular heartbeat to the vCenter Server system. This port must not be blocked by firewalls between the server and the hosts or between hosts.

NEW QUESTION 2
An attempt to delete NFS datastore from an ESXI host returns the error: Sysinfo error on operation returned the following status: Busy
Which two statements could explain this failure? (Choose two.)

• A. Storage IO Control is enabled on NFS datastore.
• B. NFS datastore is a part of Storage DRS Cluster.
• C. NFS datastore has running or registered virtual machines.
• D. NFS.VolumeRemountFrequency value is set to 30.

Answer: AC

Explanation: The busy status indicated that either storage I/O control is enabled on NFS datastore or the NFS datastore is running on registered virtual machines. In both cases, sysinfo error on operation will be returned with busy status.

NEW QUESTION 6
A VM-Host affinity rule states that VM group “X” must run on hosts in group “Y”.
If all ESXi hosts in group “Y” fail, which is the resulting behavior with vSphere HA enabled?

• A. The virtual machines in group “X” will failover to hosts that do not belong to group “Y”, but will vMotion back to hosts in group “Y” when they become available.
• B. The virtual machines in group “X” will not failover to hosts that do not belong to group “Y”.
• C. This scenario is not possible because vSphere HA and DRS cannot work together.
• D. The virtual machines in group “X” will only fail over to hosts that do not belong to group “Y” if they are marked as “High” VM Restart Priority within vSphere HA.

Answer: B

NEW QUESTION 7

Answer: B

NEW QUESTION 9
Which two statements correctly describe VM-Host affinity rules? (Choose two.)

• A. After creating a VM-Host affinity rule, its ability to function in relation to other rules is not checked.
• B. After creating a VM-Host affinity rule, its ability to function in relation to other rules is predetermined.
• C. When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules are applied equally.
• D. When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules will be ranked.

Answer: AC

Explanation: If you create more than one VM-Host affinity rule, the rules are not ranked, but are applied equally. Be aware that this has implications for how the rules interact. For example, a virtual machine that belongs to two DRS groups, each of which belongs to a different required rule, can run only on hosts that belong to both of the host DRS groups represented in the rules.
When you create a VM-Host affinity rule, its ability to function in relation to other rules is not checked. So it is possible for you to create a rule that contacts with the other rules you are using. When two VM-Host affinity rules conflict, the older one takes precedence and the newer rule is disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored.

NEW QUESTION 10
Which two statements correctly describe VM-VM affinity rules? (Choose two.)

• A. vSphere DRS attempts to keep the virtual machines together on the same ESXi host.
• B. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is disabled.
• C. vSphere DRS attempts to keep the virtual machines on separate ESXi hosts.
• D. When two VM-VM affinity rules conflict, the newer one takes precedence and the older rule is disabled.

Answer: AB

NEW QUESTION 11
Which are the two network requirements for a VMware vSAN 6.5 cluster? (Choose two.)
