NetApp NS0-157 Online Questions & Answers

• Question 241:

  Node cl-02 needs to fail over for scheduled maintenance. The node has NAS LIFs on it. The failover needs to be non-disruptive to the NAS clients. Which command accomplishes this task?

  A. system node halt –ofnode cl
  B. system node reboot –ofnode cl
  C. storage failover takeover –ofnode cl
  D. storage failover takeover –ofnode cl
  C. storage failover takeover –ofnode cl

  The aggregate relocation can be avoided during this takeover instance by using the bypassoptimization parameter with the storage failover takeover command. To bypass aggregate relocation during all future planned takeovers, set the bypasstakeoveroptimization parameter of the storage failover modify command to true.

• Question 242:

  When assigning shelf IDs to SAS-connected shelves, which statement is true?

  A. They only need to be unique within an HA pair.
  B. They only need to be unique within a stack.
  C. They only need to be unique within a node.
  D. They need to be unique within a cluster.
  A. They only need to be unique within an HA pair.

  IDs must be unique within an HA pair. Reference: https://library.netapp.com/ecmdocs/ECMP1256807/html/GUID-FF56A1A7- F2ED-4F3D-BC2A-366609422B4D.html

• Question 243:

  An unexpected network outage has occurred and you have lost access to an NFS share inside an SVM on your cluster. What is causing the problem?

  A. The broadcast domain does not have a failover policy defined.
  B. The MTU setting for the port is incorrect.
  C. The failover group does not have the proper targets defined.
  D. The current port is already hosting a LIF.
  A. The broadcast domain does not have a failover policy defined.

• Question 244:

  What is considered when selection LS mirror copy? (choose three)

  A. If an LS mirror copy is on the same node as the network module that fields the request, the network module uses that LS mirror copy
  B. If a write request goes to LS mirror, It forward it to flexvol
  C. if no LS mirror copy is on the same node as the network module that fields the request, the network module uses an up-to-date LS mirror copy on another node.
  D. If a write request goes to LS mirror, it returns error.
  A. If an LS mirror copy is on the same node as the network module that fields the request, the network module uses that LS mirror copy
  C. if no LS mirror copy is on the same node as the network module that fields the request, the network module uses an up-to-date LS mirror copy on another node.
  D. If a write request goes to LS mirror, it returns error.

• Question 245:

  What happens if a load Sharing (LS) mirror replies a Vserver root volume to any node in the cluster and you promote one of the mirror destinations?

  A. All clients temporarily gain read/write access to the root volume
  B. The original source volume is prevented from becoming stale.
  C. All clients must re mount.
  D. There is no disruption for any connected clients.
  A. All clients temporarily gain read/write access to the root volume

• Question 246:

  Which statement is true about establishing a SnapMirror relationship in clustered data ONTAP?

  A. It sets up the relationship, but does not start the initial transfer
  B. It sets up the relationship on the source node only
  C. It sets up the relationship and starts the initial data transfer
  D. It sets up the relationship and creates the destination volume
  A. It sets up the relationship, but does not start the initial transfer

• Question 247:

  A customer wants different performance characteristics for applications that are using LUNs. They want to control the performance for FCP LUNs. Which two clustered Data ONTAP features foQoS would you use to accomplish this task? (Choose two.)

  A. setting the policy group for the SVM that is hosting the LUNs for the customer's application
  B. setting the policy group for the volumes that are hosting the LUNs for the customer's applications
  C. setting the policy group for the FCP target ports that are being used for the LUNs
  D. setting the policy group for the igroups mapped to the LUNs that are hosting the customer's applications
  A. setting the policy group for the SVM that is hosting the LUNs for the customer's application
  D. setting the policy group for the igroups mapped to the LUNs that are hosting the customer's applications

• Question 248:

  Storage QOS maximum throughput limits can be defined in terms of:

  A. IOPS only
  B. MB/s only
  C. IOPS or MB/s
  D. IOPS and MB/s
  C. IOPS or MB/s

  ---

  Storage QoS workload management (available in clustered Data ONTAP 8.2 and later) allows you to define service levels by creating policies that control the resources that can be consume by individual files, volumes or LUNS ?or entire SVMs to manage performance capacity limits (defined in terms of a maximum value for IOPS or MB/sec) on a group of files or volumes or LUNs within an SVM or on the entire SVM.

• Question 249:

  A customer enables Flash Pool with SSD storage pools for an HA pair using a single SSD hot spare. The client has assigned aggregates from only cl-01 to Flash Pool storage pool. One of the SSDs in the storage pool fails and the customer observes that the SSd hot spare did not take the place of the failed drive.

  Why did this happen?

  A. The SSD hot spare is owned by cl-02.
  B. cl-01 contains an SSD aggregate.
  C. The minimum spare count option is set to 0.
  D. The SSD storage pool already contained the maximum number of disks.
  D. The SSD storage pool already contained the maximum number of disks.

  A. LDAP integration
  B. workgroup access
  C. role-based access control
  D. mixed-mode security
  A. LDAP integration
