Huawei Certified ICT Associate – SD-WAN (HCIA-SD-WAN) — Question 28

In a dual-link backup scenario, the active/standby link switchover mode is set to priority. When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?

Answer options

• A. 20
• B. 10
• C. 15
• D. 5

Correct answer: B

Explanation

The correct answer is 10 Echo intervals, as this is the defined wait time for the AP to ensure stability before reverting to the original link. Other options do not align with the specified configuration and timing for link recovery in this scenario.
