A storage administrator needs to ensure that an ONTAP FC LUN is accessible for a remote data center. The ISL ports are reporting errors. The trunkshow command output from a Brocade switch is shown below.
- A. Set the ISL ports as N_Ports
- B. Set the ISL ports as E_Ports
- C. Set the ISL ports as F_Ports
- D. Set the ISL ports as FL_Ports
正解: B
解説:
On each switch fabric, you must configure the switch ports that connect the Inter-Switch Link (ISL). These ISL ports are otherwise known as the E-ports.

質問 24
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. Asymmetric Namespace Access (ANA) was not properly configured
- B. The wrong NQN was mapped to the subsystem
- C. The NVMe was not configured on the test0 SVM
- D. The wrong WWPN was used in the discovery command
正解: B
解説:
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:

質問 30
Click the Exhibit button.
A 4-node cluster was expanded with two news nodes (Nodes 5 and 6). You are now attempting to set up four FC LUNs on the two new nodes that use the ps2 igroup name, although FC ping works. LUNs on the previous four nodes are discoverable, but the four new LUNs on the new controllers are not discoverable.
Referring to the exhibit, what is the problem?
- A. The portset must be configured to reflect Nodes 5 and 6.
- B. Selective LUN Mapping (SLM) is not configured for this HA pair.
- C. The zones between the hosts and LIFs are from node-05 and node-06.
- D. Igroup ps2 has the portset configured with the LIFs.
正解: A
質問 31
You are creating an acceptance test plan and the subject of performance is raised. How should you define what the minimum performance should be?
- A. You should use the published maximum performance specifications for this system.
- B. You should use the published minimum performance specifications for this system.
- C. You should work with the customer to understand their performance expectations and determine the minimum performance they require for the application this system will support.
- D. You should look up the test results for a similar system in previous performance testing and use those numbers.
正解: C
質問 32
A customer wants to deploy NVMe/FC along with an existing FC SAN fabric using ONTAP 9.8. In this scenario, which two actions are correct? (choose two)
- A. Enable NVMe/FC on the existing FC SVM
- B. Create new zoning on fabric switches
- C. Upgrade your FC switches from 16GB to 32GB
- D. Use existing zoning on fabric switches
正解: A,D
解説:
Because NVMe/FC simply swaps command sets from SCSI to NVMe, it is an easy transition to make. NVMe/FC uses the same FC transport and therefore the same hardware from the host, through the switch and all the way to the NVMe/FC target port on the storage array. Thus, NVMe/FC implementations can use existing FC infrastructure, including HBAs, switches, zones, targets, and cabling.

質問 33
Exhibit.
A customer is testing a dual-fabric FC SAN configuration as shown in the exhibit and the zones are implemented on the switches shown below.
If all the nodes are in the SLM reporting nodes list, hoe many path per LUN should the customer expect when simulating an FC SFP failure by bringing LIF_3 offline?
- A. 4 paths
- B. 7 paths
- C. 3 paths
- D. 15 paths
正解: B
質問 34
For which two purposes would the use of VLAN's be beneficial? (Choose two.)
- A. to isolate SSH traffic from other IP traffic
