NEW QUESTION 11

You are installing an AFF A250 system with ONTAP 9.8 software. Your customer asks you about the recommended LIF configuration for the ISCSI protocol. In this scenario, which two statements are correct
(choose two)

• A. Each node in an ISCSI configuration must be connected to a minimum of two ethernet switches
• B. All LIFs from the SVM are connected to a single Ethernet switch
• C. Each SVM in an ISCSI configuration must have a minimum of two LIFs per node
• D. Each SVM in an ISCSI configuration must have a minimum of one LIF per node

Answer: AC

Explanation:
It is recommended that all SVMs in ISCSI configurations have a minimum of two LIF's per node in separate Ethernet networks for redundancy and MPIO across multiple paths.

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

During testing, an administrator notices that the wrong subsystem was returned using the NVMe discover command. The administrator was expecting test0_subsystem as the subsystem
Referring to the exhibit, what would cause the discrepancy?

• A. The wrong NQN was mapped to the subsystem
• B. The wrong WWPN was used in the discovery command
• C. Asymmetric Namespace Access (ANA) was not properly configured
• D. The NVMe was not configured on the test0 SVM

Answer: A

Explanation:
We can discard that ANA was not properly configured becase this is not a problem about multipathing. We can discard WWPN because this is an NVMe configuration where WWPN is not involved
We can discard that NVMe was not configured because we wouldn't be able to even run that command if that's true
Configure the NQN correctly is one of the steps when we configure NVMe You can find more information on this link:
