NEW QUESTION # 56
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.)
Answer: A,B
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.
For more detailed guidance, refer to:
* NetApp SAN Host Configuration Overview
* NetApp Best Practices for SAN ( NetApp ) ( NetApp )
NEW QUESTION # 57
A storage engineer in SAN environment needs to Identify FC ports using the company-wide naming policy.
Which command will accomplish this task?
Answer: B
Explanation:
The vserver fcp wwpn-alias set command is used to set or modify the World Wide Port Name (WWPN) aliases for Fibre Channel (FC) ports in a NetApp ONTAP environment. This command allows you to apply a company-wide naming policy to FC ports, ensuring consistent and easily identifiable naming conventions across your storage infrastructure.
For further details, you can refer to:
* NetApp Documentation on FC Management
* NetApp Community Discussion on WWPN Aliases
NEW QUESTION # 58
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?
Answer: C
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 # 59
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: C,D
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
NEW QUESTION # 60
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: C,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.
For further details, check:
* NetApp Best Practices for iSCSI
* NetApp Community Discussion on iSCSI Performance
