NEW QUESTION 5

Your customer asks you to configure a newly installed FAS8300 for an FC host connection. Referring to the exhibit, which step accomplishes this task?

• A. Configure the ports 0e and 0f as a mode of CNA
• B. Configure the ports 0e and 0f as type of target
• C. Configure the ports 0e and 0f as status admin up
• D. Configure the ports 0e and 0f as status admin down

Answer: B

Explanation:
To change the port type from initiator to target you need to take the port offline The ports need to be on target mode to present LUNs to the hosts.

Answer: BC

NEW QUESTION 7

You create a new iSCSI SVM and secure iSCSI sessions by using both Challenge-Handshake Authentication Protocol (CHAP) and iSCSI Access Control Lists (ACL).
In this scenario, in which two ways are you securing your iSCSI implementation? (Choose two.)

• A. CHAP creates a hash value for the username and shared secret.
• B. iSCSI ACLs are applied to the initiator configuration to provide an IP address of the targets.
• C. CHAP encrypts all iSCSI session I/O.
• D. iSCSI ACLs are applied to the target configuration to provide an IP address of the initiators.

Answer: AD

NEW QUESTION 8

What is the default Ethernet packet size (or MTU - Maximum Transmission Unit) for Ethernet ports on Ethernet switches?

• A. 2112 bytes
• B. 9000 bytes
• C. 1500 bytes
• D. 12000 bytes

Answer: C

NEW QUESTION 9

Which row of items should you look up in the IMT (Interoperability Matrix Tool) when designing a NetApp Storage Solution for a customer?

• A. Host OS & patches, FC WWPN, Volume Manager, File System version
• B. Host OS, iSCSI IQN, Volume Manager, Clustering
• C. Host OS & patches, HBA driver, Volume Manager, File System, Clustering
• D. Host OS, HBA driver, Host Memory & CPU Speed, File System, Clustering

Answer: C

NEW QUESTION 10

You have a two node Netapp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster
nodes. Which action would solve this issue?

• A. Increase the queue depth on the target ports
• B. Configure additional FC target ports
• C. Increase the queue depth on the initiator ports
• D. Configure additional FC ports on the hosts

Answer: B

Explanation:
Adding more FC initiators on host will not solve this bottle-neck situation, we can try to increase the queue depth but we need the number of hosts and the number of target ports to calculate it correctly.
We need to add more FC target ports on our storage to keep the load balanced and distributed You can find more information on this link

• A. The number of LIFs using a physical port * 256
• B. The sum of the Queue Depth setting for all hosts using a physical port
• C. The number of LIFs using the physical port * Maximum Host HBA Queue Depth setting
• D. The number of physical ports * 2048

Answer: C
