A vSphere administrator needs to migrate a virtual machine to another datastore and host without disrupting virtual machine users.
Which technique should the vSphere administrator use?
A. Enhanced vMotion
B. High Priority vMotion
C. Low Priority vMotion
D. Storage vMotion
Correct Answer: A
Explanation/Reference:
Explanation:
In this question, we need to migrate a virtual machine to another datastore and host without disrupting virtual machine users.
With Enhanced vMotion, we can use vMotion to migrate virtual machines to a different host and datastore simultaneously. In addition, unlike Storage vMotion, which requires a single host to have access to both the source and destination datastore, you can migrate virtual machines across storage accessibility boundaries.
In vSphere 5.1 and later, vMotion does not require environments with shared storage. This is useful for performing cross-cluster migrations, when the target cluster machines might not have access to the source cluster’s storage. Processes that are working on the virtual machine continue to run during the migration with vMotion.
Incorrect Answers:
B: With a high priority vMotion, vCenter Server reserves resources on both the source and destination hosts to maintain virtual machine availability during the migration. High priority migrations do not proceed if resources are unavailable. A high priority vMotion does not enable you to migrate a virtual machine to another datastore and host without disrupting virtual machine users unless Enhanced vMotion is used. Therefore, this answer is incorrect.
C: With a low priority vMotion, vCenter Server does not reserve resources on the source and destination hosts to maintain availability during the migration. Low priority migrations always proceed. A low priority vMotion does not enable you to migrate a virtual machine to another datastore and host without disrupting virtual machine users unless Enhanced vMotion is used. Therefore, this answer is incorrect.
D: In this question, we need to migrate a virtual machine to another datastore and host without disrupting virtual machine users. Storage vMotion is used to migrate a VM from one datastore to another. It does not migrate the VM to a different host. Therefore, this answer is incorrect.
