NEW QUESTION # 50
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?
- A. The host sees four optimized paths to the LUN
- B. The host sees two optimized paths and two non-optimized paths to the LUN
- C. The host sees two non-optimized paths and two dead paths to the LUN
- D. The host sees two optimized paths and two dead paths to the LUN
Answer: A
Explanation:
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.

NEW QUESTION # 54
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. After creation using the VSC, the administrator needs to create a LUN mapping.
- 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. The VSC cannot create datastores while hosts are in maintenance mode.
Answer: C
