300-425 Designing Cisco Enterprise Wireless Networks (ENWLSD) Questions and Answers

Questions 4

A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued on the secondary Cisco WLC and it fails. Which parameter needs to be in place to complete the configuration?

Options:

A.

A cable in the RP port

B.

The secondary Cisco WLC needs a minimum of 50 base licenses

C.

The primary Cisco WLC is already set as the secondary unit.

D.

SSO needs to be enabled

Questions 5

How does AP failover priority for access points function when configured with priority 1 or 4?

Options:

A.

When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

B.

When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

C.

When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.

D.

When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.

Options:

A.

IP Protocol 67

B.

IP Protocol 77

C.

IP Protocol 87

Questions 11

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?

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.
