Answer: C

Explanation:
Important:
A WWN pool can include only WWNNs or WWPNs in the ranges from 20:00:00:00:00:00:00:00 to 20:FF:FF:FF:FF:FF:FF:FF or from 50:00:00:00:00:00:00:00 to 5F:FF:FF:FF:FF:FF:FF:FF. All other WWN
ranges are reserved. To ensure the uniqueness of the Cisco UCS WWNNs and WWPNs in the SAN fabric, we recommend that you use the following WWN prefix for all blocks in a pool:
20:00:00:25:B5:XX:XX:XX

NEW QUESTION 9

Which formula is appropriate for calculating target port Queue Depth?

• 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

NEW QUESTION 10

Your server administrator upgraded a Windows 2016 Server from 16 Gb to 32 Gb HBAs. The application owner is now reporting slower performance to the AFF A700.
Which two actions will help troubleshoot performance on the server? (Choose two.)

• A. Verify the HBA model using Hardware Universe.
• B. Verify the HBA firmware using the Interoperability Matrix Tool.

NEW QUESTION 11

You are asked to separate production FC traffic from test development FC traffic. In this scenario, at a minimum, which two configurations would accomplish this task? (choose two)

• A. VLANs
• B. Shared igroup
• C. SVMs
• D. Cisco VSANs

Answer: CD

Explanation:
SVMs will help us to separate traffic creating production_LIFs and development_LIFs VLANs will not affect anything, because it is asking about FC traffic
Cisco VSans will help us to create separate virtual SANs within the same switch.
