NEW QUESTION 5

You created a LUN in a new volume on your Netapp ONTAP cluster. You enabled the default snapshot schedule and enabled snapshot autodelete on the volume. In this scenario, in which three situations
does the snapshot autodelete feature automatically delete snapshot copies in the volume? (choose three)

• A. The snapshot reserve space is nearly full
• B. The LUN is nearly full
• C. The overwrite reserve space is full
• D. The volume is nearly full
• E. The aggregate is nearly full

Answer: ACD

Explanation:
Depending on what is selected in the "Trigger" option, Snapshot Autodelete will automatically delete a snapshot when, either the volume space utilized, or the snapshot reserve reaches a threshold capacity
specified below.
Automatic deletion of Snapshot copies from flexible volumes Data ONTAP can automatically delete one or more Snapshot copies on the volume, provided the Data ONTAP Snapshot copy autodeletion
policy is enabled and set to trigger when the overwrite reserve is nearly full on the volume. You can find more information on this link:

NEW QUESTION 6

You have implemented FabricPool on your AFF ASA ONTAP 9.8 Cluster. An archived database has become very active, and it requires FabricPool adjustments.
Which two steps are required to address this issue? (Choose two)

• A. Use the promote cloud-retrieval-policy
• B. Remove all snapshot copies.
• C. Set the tiering-policy to none
• D. Set the space-guarantee on the volume

Answer: AC

Explanation:
Promoting all data from a FabricPool volume to the performance tier.
You can proactively retrieve all data on a FabricPool volume in the Cloud and promote it to the performance tier.
Use the volume modify command to set tiering-policy to none and cloud-retrieval-policy to promote. You can find more information on this link:

NEW QUESTION 7

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.

• B. Verify if the LUNs and namespaces are in the same volume.
• C. Verify if the version of Netapp ONTAP software is 9.5 or later
• D. Verify if there is only one LIF in the SVM

Answer: AC

NEW QUESTION 9

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. Upgrade your FC switches from 16GB to 32GB
• D. Create new zoning on fabric switches

Answer: AB

Explanation:
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.

• B. Confirm that the FC HBA driver and firmware is supported according to the Interoperability Matrix Tool (IMT)
• C. Configure portsets to support the availability of multiple paths.
• D. Configure an igroup with the WWPN from the host initiator for LUN access.
• E. Confirm that the switch firmware is supported according to the Interoperability Matrix Tool (IMT).

Answer: CDE

NEW QUESTION 11

A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.
In this scenario, what would be the reason for the disconnects?

• A. The FC host has a lower queue depth.
• B. According to the IMT, unsupported HBA firmware is in use.
• C. All of the hosts are part of the same cluster.
• D. The queue depth is not consistent across the cluster.

• B. iSCSI ACLs are applied to the initiator configuration to provide an IP address of the targets.
• C. CHAP encrypts all iSCSI session I/O.
• D. iSCSI ACLs are applied to the target configuration to provide an IP address of the initiators.

NEW QUESTION 15

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. Force the new switch to be the principle 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.

Answer: BCD

NEW QUESTION 16

You have a two node Netapp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster
nodes. Which action would solve this issue?

• A. Increase the queue depth on the target ports
• B. Configure additional FC target ports
• C. Increase the queue depth on the initiator ports
• D. Configure additional FC ports on the hosts

Answer: B

Explanation:
Adding more FC initiators on host will not solve this bottle-neck situation, we can try to increase the queue depth but we need the number of hosts and the number of target ports to calculate it correctly.
We need to add more FC target ports on our storage to keep the load balanced and distributed You can find more information on this link

NEW QUESTION 17

You have a SAN host that is only sending traffic to an ONTAP cluster using active non-optimized paths. In this scenario, over which network type does the node that is hosting the target LUN receive the
traffic?

• A. Fibre Channel network
• B. Cluster network
• C. ISCSI network
• D. Intercluster network

Answer: B

Explanation:
The Cluster Network
This is used for traffic that is going between the nodes themselves, such as system information that is being replicated between the nodes. Also, if incoming client data traffic hits a network port on a different
controller than the one which owns the disks, that traffic will also go over the cluster network.

NEW QUESTION 18
