  When a giveback occurs, the storage will be once again homed to the owning node of the disks. However, this process can be vetoed in certain conditions, such as:

  A. Reassign ownership of each disk in the aggregate to the partner node.
  B. Execute the storage aggregate relocation start command.
  C. Execute the storage failover command.
  D. Move all volumes on the aggregate to an aggregate that is owned by the partner.
  B. Execute the storage aggregate relocation start command.

  ---

  To start the aggregate relocation process us the command: storage aggregate relocation start References: https://library.netapp.com/ecmdocs/ECMP1196905/html/GUID-AE98144E- 002D-405D-88C5-198DC4B05F55.html

• Question 45:

  You just finished upgrading a cluster to ONTAP 9.1 and would like to enable NetApp Volume Encryption (NVE) on an existing volume. You do not have NetApp Storage Encryption (NSE) drives installed. Which three steps would you take to accomplish this task? (Choose three.)

  A. Replace drives with NSE drives.
  B. Modify the volume options with the 璭ncrypt true parameter.
  C. Install the NVE license.
  D. Execute the key manager setup wizard.
  E. Perform volume move operation using the 璭ncrypt-destination true parameter.
  C. Install the NVE license.
  D. Execute the key manager setup wizard.
  E. Perform volume move operation using the 璭ncrypt-destination true parameter.

  ---

  You must install the NVE license and enable onboard key management before you can enable volume encryption. You can enable encryption on a new volume or on an existing volume.

  You can use the volume move start command to enable encryption on an existing volume. You can use the same aggregate or a different aggregate.

• Question 46:

  Click the Exhibit button.

  

  Referring to the exhibit, which two statements about the connectivity from the 2-node cluster to the cluster interconnects are true? (Choose two.)

  A. The CN1610 switches were discovered by using Cisco CDP.
  B. The nodes are cabled correctly.
  C. The nodes are cabled incorrectly.
  D. The CN1610 switches were discovered by using LLDP.
  A. The CN1610 switches were discovered by using Cisco CDP.
  C. The nodes are cabled incorrectly.

  ---

  From the exhibit we see that cdp is used.

• Question 47:

  Which two features provide physical path resiliency from a Windows 2016 server to an iSCSI LUN on a 12-node ONTAP cluster? (Choose two.)

  A. broadcast domains
  B. MPIO
  C. failover groups
  D. ALUA
  B. MPIO
  D. ALUA

  Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays. These

  modules are called device- specific modules (DSMs). The concepts around DSMs are discussed later in this document.

  MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached SCSI (SAS) interfaces in Windows Server.

  Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define path prioritization for SCSI devices.

• Question 48:

  Which network interface failover group target ports are available when the system-defined failover policy is used?

  A. only the ports in the failover group that are in the LIF's home node and on the LIF's storage-failover (SFO) partner node
  B. only the ports in the failover group that are in the LIF's home node
  C. only the ports in the failover group that are in the LIF's home node and on a non- storage-failover (non-SFO) partner node
  D. all network ports from all nodes in the failover group
  C. only the ports in the failover group that are in the LIF's home node and on a non- storage-failover (non-SFO) partner node

  ---

  system-defined: Only those ports on the LIF's home node and a non-SFO partner. References: ONTAP 9. 0 Network_Management_Guide (January 2017), page 20

• Question 49:

  You want to use UTA2 ports for native FC LUN access. How do you accomplish this task?

  A. Configure the UTA2 ports as target ports with 16 Gb SFP+ transceivers.
  B. Configure the UTA2 ports as target ports with 10 Gb SFP+ transceivers
  C. Configure the UTA2 ports as initiator ports with 10 Gb SFP+ transceivers
  D. Configure the UTA2 ports as initiator ports with 16 Gb SFP+ transceivers
  D. Configure the UTA2 ports as initiator ports with 16 Gb SFP+ transceivers

  ---

  Native Fibre Channel drives attach directly to the Fibre Channel SAN, eliminating the need for a router.

  NetApp uses the marketing term "UTA2" to refer to a new generation of network adapters that can be configured as either 10-Gb Ethernet and FCoE ports or as 16-Gb FC initiator or target ports.

• Question 50:

  A customer has created an SVM in an 8-node cluster with only FC licensed on all nodes. The customer wants to limit the number of paths visible to each host. Which three technologies accomplish this task? (Choose three.)

  A. virtual SANs (VSANs) for all FC target ports to segment specific virtual ports in mapping to the application servers
  B. SLM to limit the paths from each node to the appropriate application servers
  C. FC switch zoning of a subset of the target ports to each application server's HBAs
  D. port sets to limit the paths from each node to the appropriate application servers
  E. multipathing to limit the access to the LUNs from each host
  B. SLM to limit the paths from each node to the appropriate application servers
  C. FC switch zoning of a subset of the target ports to each application server's HBAs
  D. port sets to limit the paths from each node to the appropriate application servers

  ---

  You can use FC switch zoning, portsets, and Selective LUN Map (SLM) to limit the number of paths between hosts and LUNs in configurations with multiple target ports connected to the same fabric. References: https://library.netapp.com/ecm/ecm_download_file/ECMP1636036, page 20
