• B. Add new LIFs on unused ports.
• C. Add new LIFs on the used ports.
• D. Reduce the queue depth on the used ports.

Answer: B

NEW QUESTION 7

NEW QUESTION 8

Which statement is correct regarding virtual machine alignment on VMware ESX?

• A. RDM LUNs do NOT suffer from alignment problems because they are accessed directly by VMs.
• B. A VMFS LUN with a LUN type of VMware, will always have properly aligned VMs.
• C. Alignment issues can occur on any protocol including FCP, iSCSI, FCoE, and NFS
• D. msinfo32 or mbrscan can be run for the ESX service console to check for proper alignment of VMs.

Answer: C

NEW QUESTION 9

When running diagnostic tests after an initial installation of a NetApp FAS3000 storage system, which command is used to run a comprehensive set of diagnostic tests on the entire system?

• A. all
• B. comprehensive
• C. full
• D. stress

Answer: A

NEW QUESTION 10

A customer is deploying a SAN cluster of A700 nodes and wants to ensure that the SAN cluster will maintain a quorum in the event of a rack level power failure. Which two statements are true in this scenario? (choose two.)

• A. Six nodes are required
• B. Four nodes are required
• C. Three racks are required
• D. Two racks are required

Answer: AC

Explanation:
The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.
So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.
We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.

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.

NEW QUESTION 12

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.
