Which of the following statements is considered best practice when changing a network policy that has been associated with an interface?

Question

Options

• AThe policy should be placed in a "shutdown" state before changes are made.
• BA new network policy should be created and applied to the interface, overwriting the previous
• CThe policy must first be removed from the interface, then modified and re-applied to the interface.
• DBefore the policy can be changed, it must be deleted with the no network qos <policy- id>
• EBefore any changes are made to the policy, all network interfaces where the policy is applied

• A
  6% (2)
• B
  82% (27)
• C
  9% (3)
• D
  3% (1)

Explanation

Creating and applying a new policy (B) is best practice because it provides an atomic replacement - the interface is never left in an unprotected or unconfigured state, and the transition happens in a single operation without service disruption.

Why the distractors are wrong:

• A is wrong because network QoS policies don't have a "shutdown" state - that concept applies to interfaces, not policies.
• C is wrong because removing the policy first leaves the interface unprotected during the gap between removal and re-application.
• D is wrong because deleting the policy entirely with no network qos destroys the configuration; you'd then have to rebuild from scratch and the interface would be uncovered in the meantime.
• E (incomplete, but implies removing from all interfaces first) is wrong for the same reason as C - it causes unnecessary disruption across multiple interfaces.

Memory tip: Think "Overwrite, don't orphan" - always push the new policy on top of the old one so the interface is never left without coverage. If you remove first, you create a window of risk; if you overwrite, there's no gap.
