Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q49-Q54):

NEW QUESTION # 49
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?

  • A. Quiesce I/O to the LUN.
  • B. Map the LUN to a host.
  • C. Ensure that the LUN is the only one in the volume.
  • D. Ensure that the LUN Is unmapped from the host.

Answer: A

Explanation:
To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN.
This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.
For further details, refer to:
* NetApp Documentation on Snapshot Consistency
* NetApp Best Practices for Snapshot Management


NEW QUESTION # 50
An administrator creates a new volume and a LUN for an SAN-connected application that uses snapshots. The application has fast-growing data that is constantly being populated and deleted afterwards.
Which option can be set to manage the space automatically?

  • A. Disable volume snapshot autodelete.
  • B. Unmap the LUN.
  • C. Enable automatic resizing on the volume.
  • D. Enable space reservation on the LUN.

Answer: C

Explanation:
To manage space automatically for a volume containing a LUN with fast-growing data, enabling automatic resizing on the volume is recommended. This feature allows the volume to grow dynamically as needed, accommodating the fluctuating data size without manual intervention. This helps in managing storage efficiently and ensures that the application has the required space.
For further details, refer to:
* NetApp Documentation on Volume Management
* NetApp Community Discussion on Automatic Resizing


NEW QUESTION # 51
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)

  • A. Connect host and storage ports to the same switches.
  • B. Configure Jumbo frames In the entire data path.
  • C. Zone the host by using the host WWPNs.
  • D. Decrease the default queue depth on the host to eight.

Answer: A,B

Explanation:
To ensure the best performance in an iSCSI SAN implementation:
* Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
* Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal
* performance.
For further details, check:
* NetApp Best Practices for iSCSI
* NetApp Community Discussion on iSCSI Performance


NEW QUESTION # 52
A customer wants to Implement a NetApp AFF system at a small remote site that has two ESXi servers that require SAN storage from the NetApp ONTAP based storage system. The servers will be directly connected, because the customer does not want to deploy any switches.
Which protocol should the customer use?

  • A. FCoE
  • B. FCP
  • C. NFS
  • D. iSCSI

Answer: D

Explanation:
For a small remote site with two ESXi servers requiring SAN storage and no switches, the recommended protocol isiSCSI. iSCSI allows for direct connectivity between the servers and the NetApp ONTAP storage system using standard Ethernet infrastructure, which is suitable for environments without Fibre Channel switches.
For more information, see:
* NetApp iSCSI Configuration Guide


NEW QUESTION # 53
An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1that needs to move to node2. The SAN hosts use ALUA.
Based on this requirement, what must be taken offline to correct the situation?

  • A. LUN
  • B. Volume
  • C. SVM
  • D. LIF

Answer: D

Explanation:
To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.
For more details, see:
* NetApp Community on Moving LIFs
* NetApp Documentation on SAN LIFs
