NEW QUESTION 5

Changes to your organization requires access to an SVM be given to a group of individuals. Your company uses Active Directory as a method of access control. You decide to use the security login create - vserver engCluster -user-or-group-name CORP\Admins -application ssh -authmethod domain -role vsadmin command.
In this scenario, which access rights will this command grant?

• A. read only rights to the SVM engCluster for Active Directory group CORP
• B. vsadmin rights to the SVM engCluster for Active Directory group CORP\Admins
• C. vsadmin rights to the SVM CORP for Active Directory group CORP\Admins

Answer: B

NEW QUESTION 6

You deployed a new SVM for FC access, and you used the vserver fcr, create -vserver svm1 - status-admin up command to enable FC service on the SVM. You then created the LIFs for the FC protocol. When you review the status of the LIFs, they show that the admin status is up, but the operational status is down. You have already verified that the ports are physically connected.
In this scenario, what is the next step to bring the LIFs up?

• A. Use the network interface modify command to change the operational status of the LIFs.
• B. Create at least one zone that contains your SVM LIF WWPNs and an initiator.
• C. Verify that an FC license is applied on your system.
• D. Disable the SAN switch port where your NetApp storage is connected.

Answer: B

NEW QUESTION 7

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 ISCSI is supported
• B. Direct Connection to the nodes from the hosts with ISCSI is not supported
• C. Direct Connection to the nodes from the hosts with FC is not supported
• D. Direct Connection to the nodes from the hosts with FC is supported

Answer: AC

Explanation:
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. You can find more information on this link:

NEW QUESTION 8

You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

• A. Set the queue depth on the host to 8
• B. Update the HBA driver
• C. Zone the host by using the host WWNNs
• D. Use the Netapp Virtual Storage Console to configure the host settings

Answer: BD

Explanation:
Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.
We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth
Installing VSC and updating the HBA driver are best practices recommended by Netapp

NEW QUESTION 9

You have deployed an AFF 400 systems for ISCSI workloads and want to ensure maximum performance to the hosts.
In this scenario, which two steps should be configured? (Choose two)

• A. Enable Jumbo frames on the network switch
• B. Enable Jumbo frames on the LIF
• C. Enable Jumbo frames on the broadcast domain
• D. Enable Jumbo frames on the IPspace

Answer: AC

Explanation:
Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of
failure.
Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network
performance substantially.

NEW QUESTION 10

• C. Set the target port speed to match the switch port speed.
• D. Set the target port speed lower than the switch port speed.

Answer: B

NEW QUESTION 17

You are configuring FC ports on front-end SAN switches for a 4-node Metrocluster configuration across two data centers. You need to ensure that each data center serves FC LUNs when an FC port goes
offline in one data center. In this scenario, which front end switch setting must be modified to avoid overlap when a new port comes online?

• A. NPIV enabled
• B. NPIV reject
• C. WWPN reject
• D. ANA mapped
• E. WWNN reject

Answer: A

Explanation:
Best practice: NPIV is required for FC LIFs to operate correctly. Before creating FC LIFs, make sure that any fabrics attached to an ONTAP system have NPIV enabled.

NEW QUESTION 18

Which two components should be installed to support VMware VMFS6 datastores in an environment with only Ethernet switches? (Choose two)

• A. V_StorageAttach license
• B. Host Utilities
• C. NetApp Virtual Storage Console
• D. iSCSI licenses

Answer: CD

Explanation:
Installing VSC is the best practice recommended by Netapp when you use VMware and this is an environment with only Ethernet switch, so ISCSI licenses are needed to present LUNs to the Virtual
environment.
