Question 11

- (Exam Topic 3)
A customer is deploying a SAN cluster of A700 nodes and wants to ensure that the SAN cluster will maintain a quorum in the event of a rack level power failure. Which two statements are true in this scenario? (choose two.)

A. Six nodes are required

B. Four nodes are required

C. Three racks are required

D. Two racks are required

Correct Answer:AC
The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.
So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.
We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.

Question 12

- (Exam Topic 1)
An administrator who is using the Virtual Storage Console (VSC) creates a new FC datastore on an existing volume. While the datastore was provisioned, two hosts were in maintenance mode. When the maintenance was completed, the two hosts do not have access to the new datastore, but they have access to other datastores on the same volume.
In this scenario, what caused this result?

A. The VSC cannot create datastores while hosts are in maintenance mode.

B. During host maintenance, the FC HBAs were replaced with different FC HBAs.

C. The VSC created a new igroup that contains only the hosts that were online during the datastore creation.

D. After creation using the VSC, the administrator needs to create a LUN mapping.

Correct Answer:C
