350-601 Question #561: Real Exam Question with Answer & Explanation

Question

An engineer must integrate Cisco ACI with VMware vCenter. The virtualization team configured the necessary port groups and assigned them to virtual machines through VMware vCenter. The final port group configuration must be protected from being changed by Cisco APIC. Which action accomplishes these goals?

Options

• ACreate the VMM domain with switch mode set to AVE.
• BSet the VMM domain access mode to Read Only Mode.
• CConfigure the VMM domain with tag collection.
• DActivate CDP and LLDP in the VMM domain.

Explanation

To integrate Cisco ACI with VMware vCenter while preventing the APIC from altering existing vCenter port group configurations, the VMM domain's access mode must be set to Read Only. This ensures APIC can monitor but not modify the network settings.

Common mistakes.

• A. Creating a VMM domain with switch mode set to AVE (Application Virtual Edge) is for specific service deployments and does not control the APIC's write access to vCenter port group configurations.
• C. Configuring the VMM domain with tag collection allows the APIC to collect VM tags, but it does not determine whether the APIC can modify port group settings.
• D. Activating CDP and LLDP in the VMM domain facilitates physical and virtual switch discovery and topology mapping, not the control of write access to vCenter configurations by the APIC.

Concept tested. Cisco ACI VMM domain Read Only mode
