Question 1

An administrator is asked to create a Dynamic Disk Pools (DDP) pool from eleven 12 TB disks with the requirement that there is adequate space available for a reconstruction if a drive in the pool fails.

In this scenario, what should the administrator do to satisfy this requirement?

ACreate the disk pool, and then edit the pool to reserve 12 TB of space

BCreate the disk pool, and then add another 12 TB drive to the pool

CCreate the disk pool, and then the system automatically reserves 12 TB of space

DCreate the disk pool, and then create a hot spare on another 12 TB disk

Answer : C

Create the Disk Pool:

Step: Use the SANtricity System Manager to create a DDP with the eleven 12 TB disks.

Reason: The DDP automatically reserves space for reconstruction purposes.

Automatic Space Reservation:

Functionality: The system automatically reserves adequate space for reconstruction when a disk fails.

Confirmation:

Verify: Check the pool's configuration to ensure the space is reserved for reconstruction.

Result: The system will show the reserved space within the DDP configuration.

Question 2

What is represented by the Headroom graph on the SANtricity System Manager performance tab?

Athe percentage of I/O associated with the backend disk drives

Bthe remaining performance capability of the physical objects in the storage system

Cthe percentage of CPU processing capacity that is being used by the operations on the system

Dthe resources that are being consumed by a defined workload

Answer : B

The Headroom graph in SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.

This helps in understanding how much additional load the system can handle before reaching its performance limits.

Reference: NetApp SANtricity System Manager User Guide, which explains the performance monitoring features.

Question 3

Click the Exhibit button.

Referring to the exhibit, which cable is an InfiniBand 4X connector?

Answer : B

Identify Connector Types:

Step: Examine the connectors in the exhibit to identify the InfiniBand 4X connector.

Reason: InfiniBand 4X connectors have a distinct appearance and size.

Connector Characteristics:

Observation: Connector 1 in the exhibit is labeled as 0.74 in (13.8 mm), which matches the size and appearance of an InfiniBand 4X connector.

Verification:

Cross-Reference: Confirm with NetApp and industry standards for InfiniBand connectors.

Result: Connector 1 is the InfiniBand 4X connector based on size and design.

Question 4

Click the Exhibit button.

Referring to the exhibit, which three steps would you take to solve the problem shown in the event log? (Choose three.)

ASwap out the SFP in the controller port

BSwap out the FC cable

CReinitialize the FC switch

DMove the connection to another controller port

ESwap out the HBA on the FC switch

Answer : A, B, D

Step: Replace the SFP (Small Form-factor Pluggable) module in the controller port.

Reason: Faulty SFPs can cause link issues and errors.

Swap Out the FC Cable:

Step: Replace the Fibre Channel cable connecting the controller port.

Reason: Damaged or faulty cables can lead to intermittent connectivity issues.

Move the Connection to Another Controller Port:

Step: Connect the Fibre Channel cable to a different port on the controller.

Reason: The current port may be faulty, and using another port can help isolate the issue.

Question 6

Which iSCSI setting would you change from its default value to increase the throughput of an iSCSI host port on a NetApp E-Series system?

Amaximum transmission unit (MTU)

Bflow control

CChallenge-Handshake Authentication Protocol (CHAP)

DTime to Live (TTL)

Answer : A

To increase the throughput of an iSCSI host port on a NetApp E-Series system, you should change the maximum transmission unit (MTU) setting from its default value.

Maximum Transmission Unit (MTU): The MTU size determines the largest packet that can be sent over the network without needing to be fragmented. By increasing the MTU size, you can reduce the overhead associated with packet processing and improve throughput. For example, setting the MTU to 9000 bytes (Jumbo Frames) can enhance performance for iSCSI traffic.

Question 7

Which file contains the configuration for a multipath driver for FC on Linux systems?

A/etc/kernel/mp.conf

B/opt/multipath/multipath.cnf

C/etc/multipath.conf

D/etc/dm-multipath.conf

Answer : C

The multipath configuration file for Fibre Channel (FC) on Linux systems is typically /etc/multipath.conf.

This file is used to define multipath settings and policies, such as path grouping, path selection, and failover behavior.
