Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q12-Q17):

NEW QUESTION # 12
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)

Answer: A,B

Explanation:
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
* Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
* Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216:
This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
* NetApp Documentation on NVMe over TCP
* Cisco Documentation on Jumbo Frames


NEW QUESTION # 13
A customer is migrating FC-mounted VMFS datastores using SnapMirror from their existing NetApp ONTAP cluster to their new ONTAP cluster. After breaking the SnapMirror relationship on the destination cluster, what does the customer need to do before mapping the LUN to the VMware hosts?

Answer: D

Explanation:
After breaking the SnapMirror relationship, the LUN serial number must be updated to avoid conflicts on VMware hosts when mapping the LUNs, ensuring proper identification and access.


NEW QUESTION # 14
Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)

Answer: A,B

Explanation:
SnapMirror active sync provides synchronous replication with automatic failover for SAN workloads, and MetroCluster IP offers synchronous data replication with integrated automatic failover for disaster recovery across sites.


NEW QUESTION # 15
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)

Answer: A,C

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 # 16
An engineer is troubleshooting FC connectivity issues on a customer's system and sees the following output from the network fcp adapter showcommand:

According to the output, what is the domain ID of the switch that is connected to port 2a of node n2?

Answer: D

Explanation:
The domain ID of the switch is indicated by the first two digits of the port address. For port 2a of node n2, the port address is 10020, where "10" represents the domain ID of the connected switch.


NEW QUESTION # 17
