Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q57-Q62):

NEW QUESTION # 57
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)

A. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9000.
B. Modify the Cisco Nexus switches to use an MTU of 9216.
C. Modify the Cisco Nexus switches to use an MTU of 9000.
D. Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216.

Answer: B,D

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 # 58
A storage administrator has a NetApp AFF SAN cluster in a multitenant environment. Another user has requested access to perform only replication within a specific SVM to another cluster.
Which default role would be used in this scenario?

A. readonly
B. backup
C. vsadmin-protocol
D. vsadmin-backup

Answer: D

Explanation:
In a multitenant environment where a user needs access only to perform replication within a specific SVM to another cluster, the default rolevsadmin-backupis appropriate. This role provides thenecessary permissions to manage backup and replication tasks without granting broader administrative rights.
For more details, see:
* NetApp Documentation on User Roles
* NetApp Community Discussion on Roles

NEW QUESTION # 59
A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.
Which protocol is used for the discovery of controllers?

A. mDNS
B. LLDP
C. TFTP
D. PXE

Answer: A

Explanation:
For automatic host discovery in a four-node NetApp AFF cluster using NVMe/TCP, the protocol used is mDNS (Multicast DNS). mDNS allows for the discovery of controllers and other networked devices without the need for a centralized DNS server, simplifying the setup process in environments that support NVMe over TCP.
For further information, refer to:
* NetApp Documentation on NVMe/TCP
* NetApp Community on Host Discovery

NEW QUESTION # 60
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?

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

Answer: D

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 # 61
A LUN Is displaying 90% used space in the NetApp ONTAP CLI, but a Windows Server shows only 10% used space.
What is the first step to take to address this issue?

A. Disable space allocation.
B. Disable automatic resizing.
C. Enable space allocation.
D. Enable automatic resizing.

Answer: C

Explanation:
When a LUN shows 90% used space in the NetApp ONTAP CLI but a Windows Server shows only 10% used space, the discrepancy is often due to how space allocation is handled between the two systems. Enabling space allocation ensures that the ONTAP system accurately reflects the actual space usage as reported by the host system, in this case, the Windows Server. This adjustment allows ONTAP to reclaim and manage space more effectively, aligning the reported usage between the ONTAP system and the host.
For more information, refer to:
* NetApp Community Discussion on Space Allocation
* NetApp Documentation on Space Usage
