QUESTION 25
You are configuring an ONTAP solution for FC host connectivity.
In this scenario, how should the cluster be configured? (Choose two.)
A. The SVM must be configured for Ethernet LIFs.
B. FC ports must be configured as initiators.
C. FCP must be licensed on the cluster.
D. FC ports must be configured as targets.
Answer: BC
Explanation:
You can configure the FC and the FCoE protocols on the SVM for SAN hosts. LIFs are created on the most suitable adapters and assigned to port sets to ensure data path redundancy. Based on your requirements, you can configure either FC, FCoE, or both the protocols.
Before you begin
The FCP license must be enabled on the cluster.
All the nodes in the cluster must be healthy.
Each node must have at least two correctly configured ports for each protocol (FC and FCoE).
QUESTION 26
What are three volume-level storage efficiency features of ONTAP? (Choose three.)
A. deswizzle

QUESTION 27
A customer has a 1,000 GB volume used as a NAS share that has 3x 100 GB files and has no existing Snapshot copies. The customer creates a Snapshot copy of the volume, adds a 500 Gb file to the volume, and then deletes one of the 100 GB files from the volume.
How much free space is in the volume in this scenario?
A. 500 GB
B. 200 GB
C. 300 GB
D. 600 GB
Answer: B
Explanation:
Snapshot copies minimize disk consumption by preserving individual blocks rather than whole files. Snapshot copies begin to consume extra space only when files in the active file system are changed or deleted. When this happens, the original file blocks are still preserved as part of one or more Snapshot copies.

C. only the ports in the failover group that are in the LIF’s home node and on a non- storage-failover (non-SFO) partner node
D. all network ports from all nodes in the failover group
Answer: C
