NEW QUESTION 84
You want to move a SAN LIF and preserve its configuration information and avoid rezoning the switch fabric. In this scenario, which two steps must be performed to fulfill this goal? (Choose two)
- A. Move the SAN LIF to another node in a cluster on a different storage virtual machine (SVMs)
- B. Take the SAN LIF offline before it is moved
- C. Keep the SAN LIF online before it is moved
- D. Move the SAN LIF to another node in a cluster on existing storage virtual machine (SVMs)
Answer: B,D
Explanation:
Moving SAN LIFs
If a node needs to be taken offline, you can move a SAN LIF to preserve its configuration information, such as its WWPN, and avoid rezoning the switch fabric. Because a SAN LIF must be taken offline before it is moved, host traffic must rely on host multipathing software to provide nondisruptive access to the LUN. You can move SAN LIFs to any node in a cluster, but you cannot move the SAN LIFs between storage virtual machines (SVMs).

NEW QUESTION 85
You have a 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?
- A. 80 GB
- B. 20 GB
- C. 60 GB
- D. 40 GB
Answer: C
Explanation:
Both LUN created are inheriting the space reserved parameter from its volume parent, so both LUNs are thick provisioned using 20 GB each one of them and the snapshots have not increased because there has not been any changes since their creation
100GB - 20 GB - 20GB
NEW QUESTION 86

NEW QUESTION 95
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. Three racks are required
- B. Two racks are required
- C. Four nodes are required
- D. Six nodes are required
Answer: A,D
Explanation:
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.
NEW QUESTION 96
