Which management interface is selected by the Cisco APIC by default if an in band management interface and an out-of-band management interface exist?

Question

Options

• AIn-band is preferred
• BThe first configured interface is selected
• CThe interface that has the highest priority is selected
• DOut-of-band is preferred

• A
  4% (2)
• B
  2% (1)
• C
  2% (1)
• D
  91% (41)

Explanation

Out-of-band (OOB) management is preferred by default because Cisco APIC treats OOB as the more reliable, dedicated management path - it operates independently of the ACI fabric data plane, meaning you can still reach the controller even if the fabric itself has issues. Option A is wrong because in-band management, while supported, is explicitly the lower-priority option since it relies on the fabric being functional. Option B is incorrect - APIC's preference is not determined by configuration order but by interface type. Option C is a plausible distractor, but "highest priority" as a concept is backwards here: OOB is simply the default preferred type, not something you configure a priority value on.

Memory tip: Think "Out-of-Band = Out of trouble" - if the fabric goes down, OOB keeps you in control, so Cisco sensibly defaults to it.
