質問 28
An administrator has a 2node AFF ONTAP cluster named cl1. A Windows 2016 server has 10 FC LUNs mapped from the cluster , and the administrator can multiple paths to each LUN, During a scheduled storage failover, node cl1-02 took over cl1-01, and Windows server lost connectivity to all mapped LUNs but reestablished connectivity after the giveback operation finished.
In the scenario, what would cause the LUN connectivity outage?
- A. Multipathing software is not installed on the host.
- B. NPIV is not enabled on the switches.
- C. Switch zoning does not exist between the host initiator ports and the data LIFs that reside on node cl1-02.
- D. Switch zoning does not exist between the host initiator ports and the data LIFs that reside no node cl-01.
正解: A
質問 29
When does Fractional Reservation reserve space from the volume?
- A. Volume Snapshot

正解: A
質問 30
You have inherited a small FC SN infrastructure that consists of 15 servers (hosts), two Cisco MDS 9148s switches, and a 4-node NetApp AFF A300 cluster. You suspect that your predecessor did not configure zoning according to best practices.
In this scenario, what information is necessary to audit your SAN zoning? (Choose two.)
- A. SVM WWNNs
- B. Controller port WWPNs
- C. Host GBA WWPNs
- D. SVN LIF WWPNs
正解: C,D
質問 31
A customer is expanding an ONTAP 9.4 switchless 2-node FAS2750 cluster. Two AFF A220 nodes will be added to the cluster.
In addition to the cluster nodes, what else is required to perform the cluster expansion?
- A. Additional management switches are required.
- B. Additional DS224C shelves are needed.
- C. An upgrade to ONTAP 9.5 is required.
- D. Cluster switches are required.
正解: A
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. Use existing zoning on fabric switches
- B. Enable NVMe/FC on the existing FC SVM
- C. Create new zoning on fabric switches
- D. Upgrade your FC switches from 16GB to 32GB
正解: A,B
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
You have a 2-node AFF A400 serving FC LUNs. You are asked to make an instant-writable copy of a LUN in a deduplicated volume. The writable copy must not take additional space.
In this scenario, which two ONTAP features would be used? (Choose two.)
- A. volume clone
- B. file clone
- C. LUN move
- D. clone split
正解: A,B
質問 34
You are about to replace a failed Brocade Fibre Channel switch. Which three steps do you take prior to connecting the switch in the SAN? (Choose three.)
- A. Preload the zoning information from the fabric onto the new switch.
- B. Change the domain ID of the replacement switch to the domain ID of the failed switch.
- C. Clear all zoning configurations on the replacement switch.
- D. Change the core PID format of the replacement switch to the core PID format of the failed switch.
- E. Force the new switch to be the principle switch.
正解: B,C,D
質問 35
Click the Exhibit button.
You have three Linux hosts that are FC multipath connected to an AFF All SAN Array A700. A failover test is performed by shutting down both Fabric A and N2, as shown in the exhibit.
Referring to this exhibit, what happens to the remaining paths from the Linux hosts to the ASA A700 target?
- A. All paths go offline from the double failure of the switch and node.
- B. Half of the paths are active-non-optimized (ANO) and the other half are active-optimized (AO).
- C. All paths are active-optimized (AO).
- D. All paths are active-non-optimized (ANO).
正解: C
質問 36
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. full
- C. stress
- D. comprehensive
正解: A
質問 37
You need to move a LUN non-disruptively from an AFF A200 HA pair to an AFF A700 HA pair within the same 4-node cluster using the steps shown below.
1. Scan the host OS to discover all paths to the LUN.
2. Execute the lun move command to move the LUN to the AFF A/00 HA pair.
3. Remove the AFF A200 HA pair from the reporting-nodes list.
4. Add the AFF A700 HA pair to the reporting-nodes list.
What is the correct sequence in performing, these steps?
- A. 4, 3. 2. 1
- B. 3, 2, 1,4
- C. 4. 1, 2, 3
- D. 1, 2, 3. 4
正解: C
質問 38
What is a SAN best practice when initially configuring a Linux FC boot LUN?
- A. Map the WWPN of the target.
- B. Configure multipath to the LUN.
- C. Install the Host Utilities in the guest Linux OS.
- D. Disable the HBA port with the host's BIOS.
正解: A
質問 39
A customer has an existing legacy ISCSI storage environment that is connected to upstream network switches with various Windows hosts.

An administrator is configuring a SAN-only cluster. The data room that houses four AFF A220 controllers is small and not able to house the DS224C shelves. The administrator proposes to rack the shelves in a separate room that is 40 meters away from the controllers.
In this situation, how would you properly cable the controllers to the shelves?
- A. Use multimode active copper cables.
- B. Use multimode active optical cables.
- C. Use multimode passive copper cables.

質問 41
A customer experiences intermittent connectivity problems between an ESXi server and FC LUNs in an SVM. The customer has examined the nodes hosting the LUNs and both the disk and CPU performance are below 50% utilization. The customer examined the switch ports connected to the storage array, and they ate also below 50% utilization.
Which two steps would you perform next in this scenario? (Choose two.)
- A. Verify that the host is using SnapDrive.
- B. Verify that the host Ethernet interfaces are using jumbo frames.
- C. Verify that the host recommended settings were applied by Virtual Storage Console.
- D. Verify that the HBA queue depth is set properly.
正解: C,D
質問 42
Your customer asks you how to connect a host for SAN access to the newly installed AFF A400 system. In this scenario, which two statements are correct? (choose two)
- A. Direct Connection to the nodes from the hosts with FC is not supported
- B. Direct Connection to the nodes from the hosts with ISCSI is supported
- C. Direct Connection to the nodes from the hosts with ISCSI is not supported
- D. Direct Connection to the nodes from the hosts with FC is supported
正解: A,B
解説:
ISCSI-Direct-attachment: In a direct-attached configuration, one or more hosts are directly connected to the controllers.
You cannot directly attach FC or FC-NMVE SAN hosts to single nodes without using an FC switch.
