Cisco Updated 350-601 Exam Questions and Answers by lorelai

The correct answer is C. standby supervisor.

From the exhibit, the command output clearly shows:

Module 6 SUP Yes disruptive Module Upgradable and later confirms:

Module 6 EPLD upgrade is successful and 6 SUP Success.

This indicates that the EPLD upgrade was performed on a Supervisor (SUP) module, specifically module 6. In Cisco MDS 9700 architecture, supervisor modules operate in a redundant pair (active and standby). When EPLD upgrades are performed, Cisco best practice and system behavior typically upgrade the standby supervisor first, because it allows the system to maintain control-plane continuity and minimizes disruption.

The output does not mention PSU, fan, or fabric modules, eliminating options A, B, and D. The explicit reference to SUP confirms that the upgrade applies to a supervisor module.

Thus, based on the module type shown in the output and standard Cisco upgrade behavior, the EPLD upgrade is applied to the standby supervisor, making C the correct answer.

The correct answer is D. through dual fabric interconnects.

Cisco UCS X-Series achieves management high availability by using a pair of Fabric Interconnects (FIs), which provide redundant connectivity and management-plane resiliency for the chassis and its components. In UCS architecture, the fabric interconnects are the central control and management point for the compute domain, so deploying them as a redundant pair ensures that management access and infrastructure communication continue if one FI fails.

Option A is incorrect because UCS Director is an orchestration platform, not the native HA mechanism for UCS-X management components. Option B is incorrect because UCS Manager is associated with classic UCS domains and is not described as separate redundant manager instances in this context. Option C is also incorrect because Cisco Intersight is a SaaS or appliance-based management platform, but UCS-X high availability at the domain level is not achieved by running multiple Intersight instances.

The actual device-level resiliency for management in UCS-X comes from the redundant fabric interconnect design, which protects management and connectivity paths for the chassis, I/O, and compute resources. Therefore, dual fabric interconnects are the correct answer.
