Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 80

A customer is running a guest WLAN with a foreign/export-anchor setup. There is one anchor WLC in the US and two in Europe. Anchor WLC priorities are used to prefer local anchors. During a routine network audit, it is discovered that a large number of guest client sessions in the US are anchored to the WLCs in Europe.
Which reason explains this behavior?

Answer options

• A. The foreign WLC failed and recovered.
• B. The US anchor WLC failed and recovered.
• C. The US anchor WLC is anchored to itself with a priority value of zero.
• D. The anchor WLC is in the same mobility group.

Correct answer: B

Explanation

The correct answer is B because if the US anchor WLC failed and subsequently recovered, guest client sessions could default to the European WLCs during the downtime. Option A is incorrect as it pertains to the foreign WLC, which does not affect the US anchors. Option C is also wrong since a priority value of zero would not lead to connections being routed to European WLCs. Option D does not apply since being in the same mobility group does not explain why local sessions are not being anchored there.
