Question 1 of 100
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
Answer

Suggested Answer

The suggested answer is A.

In a stretched vSAN cluster, the Read Locality feature ensures that after a failover to the secondary site, 100% of the read operations are serviced by vSAN hosts on the local site where the virtual machine is now running. This reduces latency and improves performance by avoiding the need to access data across geographical distances.

Question 2 of 100
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
Answer

Suggested Answer

The suggested answer is D.

In a vSAN stretched cluster, the value that must be set in the vSAN policy if there is no requirement for data mirroring across sites is PFTT = 0. PFTT stands for Primary Failures to Tolerate and it specifies the number of site failures to tolerate. Setting PFTT to 0 indicates that no data mirroring across sites is required, which means that the cluster does not need to maintain additional copies of data on different sites.

Question 4 of 100
An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)
Answer

Suggested Answer

The suggested answer is A, E.

When setting up vSAN file services on a vSAN cluster, the security policies that are automatically enabled on the distributed port groups are Forged Transmits and MacLearning. Forged Transmits is a security policy that allows the network to accept forged transmissions from virtual machines, which is necessary for certain network configurations. MacLearning is important for managing MAC address changes and ensuring proper communication between virtual machines. These policies are crucial for the operation of vSAN file services and are automatically enabled to ensure network functionality and security.

Question 5 of 100
An administrator has been tasked to reboot a node in an encrypted vSAN cluster. The vSAN disk groups on that node become locked after rebooting the node.
Which step should be performed to exit the locked state?
Answer

Suggested Answer

The suggested answer is B.

In an encrypted vSAN cluster, if the vSAN disk groups become locked after rebooting a node, the likely issue is a loss of communication with the Key Management Server (KMS). Restoring communication with the KMS server and re-establishing the trust relationship would allow the node to retrieve the necessary encryption keys, thus unlocking the disk groups.
