Regarding the default configuration of common parameters of dual-link cold backup, which of the following statements is correct?

Question

Options

• AAC global priority is 0
• BAC personality priority is 0
• CThe dual-link backup switchback function is not enabled
• DEnable dual-link backup function

• A
  79% (26)
• B
  12% (4)
• C
  3% (1)
• D
  6% (2)

Explanation

In Huawei WLAN dual-link cold backup, the AC global priority defaults to 0, which is the baseline value used to determine AC precedence when no administrator has manually configured a higher priority - making A correct.

Why the distractors are wrong:

• B is wrong because AC personality priority (a per-AP granular setting) does not default to 0; it uses a different default value distinct from the global priority parameter.
• C is wrong because the switchback function is enabled by default in dual-link cold backup - when the primary AC recovers, APs automatically return to it without requiring manual intervention.
• D is wrong because the dual-link backup function itself is not enabled by default; an administrator must explicitly activate it through configuration before it takes effect.

Memory tip: Think of it as "zero effort, zero priority" - the global priority starts at 0 because no preference has been set yet, while the backup function itself requires active effort (manual configuration) to turn on.
