  Referring to the exhibit, which statement about the volume move process is true?

  A. Client access to the volume is blocked during this phase of operation.
  B. The initial replication phase sent 39 MB from the source to the destination location.
  C. Client access is being redirected to the destination location during this phase of the operation.
  D. The cutover process failed and is in a holding pattern before being attempted again.

• Question 53:

  Click the Exhibit button.

  

  Referring to the exhibit, the write operations would be compacted into how many WAFL blocks?

  A. 4
  B. 2
  C. 3
  D. 5
  C. 3

  ---

  4k is the block size that WAFL uses to write on each disk.

  From the exhibit: 0.5 + 1 + 2 + 1.3 + 1 + 0.5 + 0.5 + 1 + 2 KB equals 9.8 KB, which would fit in 3 WAFL blocks.

• Question 54:

  Click the Exhibit button.

  

  You create a volume as shown in the exhibit. Which statement about the new volume is true?

  A. A FlexVol volume is created on the aggregate (sas_01 or sas_02) with the most free space.
  B. A FlexVol volume is created on aggregate sas_01 can only be moved to aggregate sas_02.
  C. A FlexGroup volume is created with eight constituents.
  D. A FlexGroup volume is created with two constituents
  D. A FlexGroup volume is created with two constituents

  ---

  The Volume create parameter -aggr-list , ... - List of Aggregates for FlexGroup Constituents

  Specifies an array of names of aggregates to be used for FlexGroup constituents. Each entry in the list will create a constituent on the specified aggregate.

• Question 55:

  Click the Exhibit button.

  

  Referring to the exhibit, which statement is true?

  A. The node's aggregates have been underutilized on average for the past one hour.
  B. The node's CPU has been underutilized on average for the past one hour.
  C. The node's CPU has been overutilized on average for the past one hour.
  D. The node's aggregates have been overutilized on average for the past one hour.
  C. The node's CPU has been overutilized on average for the past one hour.

  ---

  You compute the available performance capacity by subtracting the optimal_point_counter from the current_counter. In this example, the utilization capacity for CPU_sti2520-213 is - 14% (72%-86%). This suggests that the node's CPU has been overutilized on average for the past one hour.

• Question 56:

  NetApp ONTAP uses Snapshot copies for which two features? (Choose two.)

  A. cluster peering
  B. FlexClones
  C. FlexArray FLI
  D. SMTape
  B. FlexClones
  D. SMTape

  ---

  You can create FlexClone files and FlexClone LUNs from an existing Snapshot copy of the parent files and parent LUNs contained in a FlexVol volume.

  SMTape is a high performance disaster recovery solution from Data ONTAP that backs up blocks of data to tape. It is a Snapshot copy-based backup to tape feature.

• Question 57:

  The NVM Express (NVMe) flash capacity is upgradeable in which two systems? (Choose two.)

  A. FAS9000
  B. FAS8200
  C. FAS2650
  D. AFF A700
  A. FAS9000
  B. FAS8200

  ---

  The latest generation of FAS2600, FAS8200 and FAS9000 families now support internal NVMe drives for FlashCache functionality to address this use case.

• Question 58:

  Which two features are supported by SnapLock Enterprise but not by SnapLock Compliance? (Choose two.)

  A. FlexArray
  B. privileged delete
  C. NetApp Volume Encryption (NVE)
  D. SnapMirror
  B. privileged delete
  D. SnapMirror

  ---

  Features supported by SnapLock Enterprise but not by SnapLock Compliance include:

  Note:

  Comparison table of SnapLock Enterprise and SnapLock Compliance The SnapLock Enterprise and the SnapLock Compliance features differ in terms of the options and permissions available for both the features.

• Question 59:

  Click the Exhibit button.

  

  On the first LUN entry shown in the exhibit, a hyphen (-) appears under reporting-nodes. What are two reasons why the hyphen appears? (Choose two.)

  A. The hyphen indicates that no nodes are reporting paths to the LUN.
  B. The hyphen indicates that all nodes are reporting paths to the LUN.
  C. The hyphen is the default for SLM on LUNs create in ONTAP 8.3 and later.
  D. The hyphen is the default for SLM on LUNs create before ONTAP 8.3.
  B. The hyphen indicates that all nodes are reporting paths to the LUN.
  C. The hyphen is the default for SLM on LUNs create in ONTAP 8.3 and later.

  ---

  Verify that the LUN map contains four nodes by using the lun mapping show -fields reporting-nodes command. Example cluster1::> lun mapping show -vserver SVM1 -volume vol1 -fields reporting-nodes vserver path igroup reporting-nodes -------- ----------- -------- --------------------------------------------- SVM1 /vol/vol1 ig1 cluster1-1,cluster1-2,cluster1-3,cluster1-4 If the cluster contains only four nodes and all four are included as reporting-nodes, the reporting-nodes field displays a dash (-).

• Question 60:

  Click the Exhibit button.

  

  You manage a multi-tenant NetApp storage system. You start configuring an SVM for a new customer and receive the error shown in the exhibit when you attempt to create a LIF. You verify that the IP address is correct and that the customer LIF does not already exist. However, you see that another customer is using the same IP address in their SVM.

  How would you correct this problem?

  A. Create a new VLAN for the new customer.
  B. Create the LIF with a different IP address.
  C. Create an IPspace for the new customer.
  D. Create a broadcast domain for the new customer.
  C. Create an IPspace for the new customer.

  ---

  The IPspace feature enables a single storage system to be accessed by clients from more than one disconnected network, even if those clients are using the same IP address. References: https://library.netapp.com/ecmdocs/ECMP1155585/html/GUID-4C8A392E- 290E-4F9C-91E8-EBF3E2047B06.html
