Question 6 of 114
An administrator runs a vSphere cluster containing database VMs with extremely heavy disk I/O. Database VMs are placed on a costly all-flash array. The workloads are not memory intensive.
How can the administrator ensure the most cost-effective utilization of the all-flash storage array?
    Correct Answer: A

Question 7 of 114
What could a vSphere administrator use to move a group of VMs to another port group?
    Correct Answer: D

    To move a group of VMs to another port group, a vSphere administrator can use vSphere vMotion. vSphere vMotion allows for live migration of running virtual machines from one host to another without downtime. This includes moving VMs across different networks or port groups while maintaining network connections and service continuity.

Question 8 of 114
Which action should be taken to secure iSCSI devices in a vSphere environment?
    Correct Answer: D

    To secure iSCSI devices in a vSphere environment, it is important to ensure that ESXi hosts authenticate to the target. Authentication helps to prevent unauthorized access to the iSCSI target and ensures only legitimate ESXi hosts can connect, thereby providing a secure communication channel.

Question 9 of 114
A vSphere Administrator is receiving complaints a database VM is experiencing performance issues. The VM is a member of the high priority resource pool and the cluster has not experienced contention.
Which condition should be checked to address immediate performance concerns?
    Correct Answer: D

    VM snapshots should be checked to address immediate performance concerns. Snapshots can negatively affect the performance of a virtual machine based on how long they have been in place, their depth, and the changes made to the VM and its guest operating system since the snapshot was taken. It is important not to run production VMs from snapshots on a permanent basis, as this can lead to performance degradation.

Question 10 of 114
A vSphere administrator has configured software iSCSI port binding in the environment with two VMkernel ports and four target portals.
How many iSCSI sessions would be created from bound ports to targets?
    Correct Answer: C

    In a scenario where a vSphere administrator has configured software iSCSI port binding with two VMkernel ports and four target portals, each VMkernel port establishes a session with each target portal. Therefore, the total number of iSCSI sessions will be the product of the number of VMkernel ports and the number of target portals: 2 VMkernel ports x 4 target portals = 8 iSCSI sessions.
