EMC Proven Professional – PowerMax Specialist — Question 47

What is the recommended configuration for iSCSI connections to ensure continuous access to the Dell EMC Unity storage system in the event of a failover?

Answer options

• A. Set up iSCSI interfaces to use VLAN tagging and configure the host to utilize the same VLAN
• B. Set up iSCSI interfaces on the same port of each SP and leverage the host-based multi-pathing software.
• C. Set up iSCSI interfaces on network ports on different SPs that are configured with Fail Safe Networking (FSN)
• D. Set up iSCSI interfaces on network ports that are configured with LACP on the same SP

Correct answer: C

Explanation

The correct answer is C because setting up iSCSI interfaces on different SPs with Fail Safe Networking (FSN) provides redundancy and ensures continuous access during a failover. Options A and B do not provide the necessary redundancy across SPs, while option D limits the configuration to a single SP, increasing the risk of downtime during a failure.
