At which point during VMM integration do you need to create the vDS switch within vCenter?

Question

Options

• Awhen starting up the VM
• BNo need to create the vDS, the Cisco APIC controller does that automatically.
• Cafter assigning the EPG to the VMM controller
• Dbefore defining the VLAN pool that is assigned to the VMM controller

• B
  95% (56)
• C
  3% (2)
• D
  2% (1)

Explanation

When Cisco APIC establishes a VMM domain integration with vCenter, it automatically creates and manages the vDS (vSphere Distributed Switch) as part of that process - no manual creation in vCenter is required. This automation is a core value proposition of ACI: APIC maintains the vDS lifecycle, including port group creation when EPGs are assigned to the VMM domain.

Why the distractors are wrong:

• A - The vDS must exist before any VM can use it; waiting until VM startup is far too late in the process.
• C - The vDS is created when APIC first connects to and configures the VMM domain, which happens before EPG assignment, not after.
• D - The VLAN pool is an ACI-side configuration object; you never manually create the vDS at any point relative to it - APIC handles vDS creation entirely.

Memory tip: Use the phrase "APIC owns the vDS." Just as APIC is the single source of truth for ACI policy, it also owns the corresponding vCenter constructs - you configure the VMM domain in APIC, and APIC reaches into vCenter to build what's needed automatically.
