A customer is planning to connect a Linux server to a FAS8200 using Brocade FC switches. During the initial configuration, the SVM does not log in to the fabric.
Which two statements are correct in this scenario? (Choose two.)

1. A. NPIV has not been enabled on the switches.
2. B. The switch port topology is set incorrectly to the E_Port.
3. C. ALUA has not been set up on the FAS8200.
4. D. Zoning is incorrectly configured between the Linux server and the ONTAP cluster.

Correct Answer: AC

At which storage object level is deduplication enabled?

1. A. Aggregate
2. B. Volume
3. C. Qtree
4. D. LUN

Correct Answer: B

You install an ASA AFF A400 system with 32 GB FC SFP+ modules in port 0e and 0f. After creating the SVM and configuring the FCP protocol, the physical port stays offline. Referring to the exhibit which statement is correct?

1. A. The current type of the ports must be configured as an initiator
2. B. The current mode to the ports must be configured as an FC port
3. C. The current mode for the ports must be set as an NVMe/FC port
4. D. The admin status is manually set to down

Correct Answer: B
Before using your UTA ports on a FC infraestructure, you need to modify the current mode from CNA to FC. You need to set the ports offline before you modify that parameter.

A4-node ONTAP FAS9000 cluster was used to serve I/O from six RedHat 7.3 servers. The servers were configured with maximum, queue depth.
For production purposes, an additional 60 similarly configured hosts were added to the environment. Later, the hosts started reporting random QFull errors, and the aggregated performance degraded.
Which two solutions would alleviate the QFull errors and performance problems? (Choose two.)

1. A. Remove Selective LUN Mapping (SIM) from the 4-node FAS9000 cluster.
2. B. Download the latest FC HBA driver, firmware, and BIOS, and deploy them on the hosts.
3. C. Configure and use additional FC target HBAs in the FAS9000 cluster.
4. D. Reduce FC HBA gueue depth on the hosts.

Correct Answer: CD

You are testing FCP paths failures on a 2-node Netapp AFF All SAN Array and verify that persistent ports are correctly enabled. Before testing, a host sees four optimized paths to a LUN. You perform a
node takeover and re-check the host.
Which statement is true after the node takeover?

1. A. The host sees four optimized paths to the LUN
2. B. The host sees two non-optimized paths and two dead paths to the LUN
3. C. The host sees two optimized paths and two non-optimized paths to the LUN
4. D. The host sees two optimized paths and two dead paths to the LUN

Correct Answer: A
Support for persistent ports
Beginning in ONTAP 9.8, persistent ports are enabled by default on All SAN Arrays (ASAs) that are configured to use the FC protocol. Persistent ports are only available for FC and require zone
membership identified by World Wide Port Name (WWPN).
Persistent ports reduce the impact of takeovers by creating a shadow LIF on the corresponding physical port of the HA partner. When a node is taken over, the shadow LIF on the partner node assumes the
identity of the original LIF, including the WWPNe. Before the status of path to the taken over node is changed to faulty, the shadow LIF appears as an Active/Optimized path to the host MPIO stack, and I/O is
shifted. This reduces I/O disruption because the host always sees the same number of paths to the target, even during storage failover operations.
