• B. Volume Space Reserved
• C. LUN Reservation Disabled
• D. LUN Reservation Enabled

Answer: D

NEW QUESTION 11


You are troubleshooting high CPU use on a FAS8200 with all SAS HDDs. You have SAN hosts with LUNs in a volume named vol1. You want to reduce CPU use and maintain storage efficiencies.
Referring to the exhibit which three actions will accomplish this task? (Choose three.)

• D. Enable post process deduplication.
• E. Enable data compaction.

Answer: CDE

NEW QUESTION 12

Exhibit.

You want to map a LUN to a server.
To which SAN object is the highlighted value in the exhibit added?

• A. LUN

Answer: D

NEW QUESTION 13

You need to gather information from the host systems that will be attached to the NetApp storage system using either FC or iSCSI. This information includes operating system version, patch levels, open bus slots, and cards in bus slots. What other information must you gather from the host systems?

NEW QUESTION 14

In an NVMe/FC environment, the host cannot discover the namespace on the AFF system. Referring to the exhibit, what is the problem?

• A. The host MPIO drivers are not installed
• B. NVMe is not supported on the FC adapter
• C. The NQN is not correct
• D. The NVMe service is not running on the SVM

Answer: C

Explanation:
We would not be able to run that command if NVMe is not enabled NVMe is supported on the same SVM along with FC protocol
The multipath tool on NVMe is called ANA
NQN needs to be correctly declared on the subsystem to map the new NVMe resources

What are two benefits of implementing VLANs for ISCSI configuration? (choose two)

• A. Reduced number of broadcast domains
• B. Increased performance
• C. Increased security
• D. Increased resiliency

Answer: AC

Explanation:
When you implement VLANs in large IP network infrastructures, you derive the following benefits: Increased security.
VLANs enable you to leverage existing infrastructure while still providing enhanced security because they limit access between different nodes of an Ethernet network or an IP SAN.

NEW QUESTION 20

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. 60 GB
• B. 20 GB
• C. 40 GB
• D. 80 GB

Answer: A

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
