Question #22
An administrator is setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI.
Which task is required for SAN configuration?
- A . Configure CHAP authentication.
- B . Configure DH-HMAC-CHAP authentication.
- C . Configure LIFs.
- D . Configure IPsec.
Correct Answer: C
C
Explanation:
When setting up a NetApp ONTAP AFF system for both NVMe/TCP and iSCSI, a critical task required for SAN configuration is to configure Logical Interfaces (LIFs). LIFs are necessary for network connectivity and are used by both NVMe/TCP and iSCSI protocols to communicate between the storage system and the host.
The configuration of LIFs involves creating and managing these interfaces to ensure they are correctly mapped and available for use by the respective protocols. This step is essential for the SAN setup to function properly.
For more detailed steps on configuring LIFs, you can refer to NetApp’s documentation:

Question #25
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 . Decrease the default queue depth on the host to eight.
- C . Zone the host by using the host WWPNs.
- D . Configure Jumbo frames In the entire data path.
Correct Answer: A, D
A, D
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.

Question #26
A customer requires multiple SAN and NAS protocols on a NetApp AFF cluster. The cluster must concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export.
Based on these requirements, what is the minimum data SVM count that is required?
- A . 3
- B . 4
- C . 1
- D . 2
Correct Answer: C
C
Explanation:
To concurrently serve a namespace over NVMe/FC, a LUN over FCP, a LUN over iSCSI, and an NFS export, only one data SVM (Storage Virtual Machine) is required. NetApp ONTAP allows a single SVM to support multiple SAN and NAS protocols simultaneously, enabling efficient and consolidated management of storage resources.

Question #27
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.)
- A . SnapMirror active sync
- B . SnapMirror SVM
- C . SnapMirror Synchronous
- D . MetroCluster IP
Correct Answer: CD
CD
Explanation:
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads

Question #28
What Is the storage construct that enables an NVMe client to store data in an SVM?
- A . Subsystem
- B . Namespace
- C . FlexGroup volume
- D . LUN
Correct Answer: A
A
Explanation:
In an NVMe environment, the storage construct that enables an NVMe client to store data in an SVM (Storage Virtual Machine) is a Subsystem. A subsystem is a collection of one or more namespaces, which are used to store data. This abstraction allows for efficient management and scaling of NVMe storage within the ONTAP environment.

Question #29
A customer Is deploying a new 8-node NetApp ONTAP cluster for their SAN workloads using FCP, NVMe/FC, and NVMe/TCP.
In this scenario, which statement is true?
- A . NVMe/FC and FCP require different FC ports.
- B . NVMe/TCP supports a maximum of two LIFs per node.
- C . NVMe/FC and NVMe/TCP must be configured in separate SVMs.
- D . NVMe/TCP can only run at 32Gbps or faster.
Correct Answer: A
A
Explanation:
In a NetApp ONTAP cluster using FCP, NVMe/FC, and NVMe/TCP, it is important to understand that NVMe/FC and FCP require different FC ports. This separation is necessary because the protocols, while both running over Fibre Channel, have different configurations and operational characteristics.

Question #30
A customer has a two-node NetApp ONTAP cluster that Is hosting FC LUNs for 64 SAN hosts. An administrator is tasked to add 40 more hosts to the environment.
What two actions would the administrator need to take to avoid potential performance problems with the environment? (Choose two.)
- A . Configure additional FC ports on existing hosts.
- B . Configure additional FC target ports.
- C . Configure additional SAN LIFs.
- D . Configure a higher queue depth on the target ports.
Correct Answer: BC
BC
Explanation:
When adding 40 more hosts to a two-node NetApp ONTAP cluster that is already hosting 64 SAN hosts, the following actions are necessary to avoid potential performance problems:
Configure additional FC target ports: Increasing the number of Fibre Channel (FC) target ports on the storage nodes will help distribute the I/O load more evenly, reducing the risk of bottlenecks.
Configure additional SAN LIFs: Adding more SAN Logical Interfaces (LIFs) will ensure that the increased number of hosts can connect efficiently, improving load balancing and path management.
These actions help maintain optimal performance and prevent congestion in the SAN environment.
