Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 510

An engineer must configure a Cisco UCS blade system that is managed by Cisco UCS Manager. All four connected interfaces between the blade system and the fabric interconnects must be used. Additionally, the connectivity must tolerate any link failure between the I/O module and the fabric interconnects. Which action accomplishes these requirements?

Answer options

• A. Configure chassis/FEX discovery policy action to four links.
• B. Configure port aggregation with LACP policy set to default.
• C. Configure Link Group Preference to Port Channel.
• D. Configure Firmware Auto Sync Server policy to Auto Acknowledge.

Correct answer: C

Explanation

The correct answer is C because configuring the Link Group Preference to Port Channel allows the system to combine multiple links into a single logical link, providing redundancy and load balancing. Options A and B do not specifically address the requirement for link redundancy in the context of the I/O module and fabric interconnects. Option D is unrelated to link configuration and focuses on firmware synchronization.
