質問 85
You are configuring a new Netapp ONTAP cluster and are connecting the nodes to Cisco MDS SAN switches. You connect one of the nodes to switch port fc1/11 and run the commands that are shown in the exhibit. The SAN LIFs are enabled but are not operationally online, and none of the SAN hosts can access their LUNs on the ONTAP cluster.
In this scenario, which configuration would cause this problem?
- A. Interoperability mode is not enabled on the switches
- B. NPIV is not enabled on the switches
- C. NPV is not enabled on the switches
- D. The in-order guarantee is not enabled on the switch
正解: B
解説:
in-order guarantee and interoperability mode are default configuration on a VSAN NPV is the core switch where NPIV is going to be enabled.
The NPV core switch is defined as an upstream switch on which NPIV is enabled. The NPV core switch receives traffic that is passed to it from a downstream switch that has NPV enabled on it. A switch that is in NPV mode does not switch traffic; instead, it passes traffic to the upstream NPV core switch on which NPIV is enabled.
After NPIV is enabled on the core NPV switch, the port should automatically come up (unless there are other issues).

質問 88
You want to connect a NetApp AFF A700 to a 32 Gb FC switch. The ports need to connect at 32 Gb speed.
In this scenario, which statement is correct?
- A. You need to purchase a two-port or four-port FC I/O module.
- B. The AFF A700 includes FC ports natively on the controller.
- C. You need to purchase a two-port or four-port unified I/O module that enables FC and Ethernet connectivity.
- D. The AFF A700 includes an additional FC I/O module that is already populated in each controller.
正解: C
質問 89
An administrator who is using the Virtual Storage Console (VSC) creates a new FC datastore on an existing volume. While the datastore was provisioned, two hosts were in maintenance mode. When the maintenance was completed, the two hosts do not have access to the new datastore, but they have access to other datastores on the same volume.
In this scenario, what caused this result?
- A. The VSC cannot create datastores while hosts are in maintenance mode.
- B. After creation using the VSC, the administrator needs to create a LUN mapping.
- C. The VSC created a new igroup that contains only the hosts that were online during the datastore creation.
- D. During host maintenance, the FC HBAs were replaced with different FC HBAs.
正解: C
質問 90
Referring to the exhibit, which WWPN would safely be removed from the zone?
- A. 20:09:00:a0:98:32:99:07
- B. 20:27:00:a0:98:32:99:07
- C. 50:0a:09:84:8d:7c:51:d5
- D. 21:00:00:c0:dd:19:4b:f3
正解: D
解説:
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
