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.)

1. A. Six nodes are required
2. B. Four nodes are required
3. C. Three racks are required
4. 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.

An administrator configures NVMe within an SVM for a test environment. The administrator creates an NVMe namespace and an NVMe subsystem. The administrator then maps the namespace to the subsystem. However, when the administrator establishes a connection to a supported host, the following error message appears: No discovery log entries to fetch.
What is the solution to this error?

1. A. Add the host WWPN to the subsystem.
2. B. Disable the host HBA and re-enable it to clear the buffers.
3. C. Add the host NQN to the subsystem.
4. D. Use the nvme ns-rescan /dev/nvme0 command to rescan the bus.

Correct Answer: C

You have deployed an AFF 400 systems for ISCSI workloads and want to ensure maximum performance to the hosts.
In this scenario, which two steps should be configured? (Choose two)

1. A. Enable Jumbo frames on the network switch
2. B. Enable Jumbo frames on the LIF
3. C. Enable Jumbo frames on the broadcast domain
4. D. Enable Jumbo frames on the IPspace

Correct Answer: AC
Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of
failure.
Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network
performance substantially.

You need to migrate boot LUNs from a third-party array onto a Netapp FAS8700. Which three actions are required to complete this task? (choose three)

1. A. Reboot the third-party SAN to prepare for the LUN Import
2. B. Verify third-party array support by using the Interoperability Matrix Tool (IMT)
3. C. Convert every FC target port on each controller to an FC initiator port
4. D. Convert a single FC port on each controller to an FC initiator port
5. E. Create zoning between the third-party array to the FAS8700

Correct Answer: BDE
We only need to convert one FC to initiator per node, if you need to enable multipath with 2 switches, then you need 2 ports on initiator mode per node

1. A. Increase the size of the LUN.
2. B. Increase the Snapshot Reserve.
3. C. Increase the aggregate size.
4. D. Use deduplication.

Correct Answer: C
