Show Answer Hide Answer
Correct Answer: B

The default NMSP echo interval between Cisco MSE and a Wireless LAN Controller is 15 seconds. This interval determines how frequently the MSE sends echo messages to the WLC to maintain the NMSP connection and ensure that the link is active and operational.Reference:= (CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide)


Question No. 3

An engineer is following the proper upgrade path to upgrade a Cisco AireOS WLC from version 7.3 to 8.9. Which two ACLs for Cisco CWA must be configured when upgrading from the specified codes? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, E

When upgrading a Cisco AireOS WLC from version 7.3 to 8.9, it's crucial to configure ACLs that allow necessary traffic for Cisco Central Web Authentication (CWA). The correct ACLs to configure are:

B . Permit 0.0.0.0 0.0.0.0 UDP DNS any: This ACL allows DNS queries from any source to any destination, which is essential for resolving domain names during the upgrade process.

E . Permit 0.0.0.0 0.0.0.0 UDP any any: This ACL permits all UDP traffic from any source to any destination, ensuring that services relying on UDP can continue to function during the upgrade.

These ACLs ensure that critical services like DNS resolution are not interrupted during the upgrade process, which could otherwise lead to system instability or failure to access network resources.Reference:= ( CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide )


Question No. 4

An engineer is considering an MDM integration with Cisco ISE to assist with security for lost devices.

Which two functions of MDM increase security for lost devices that access data from the network? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, C

Mobile Device Management (MDM) integration with Cisco ISE increases security for lost devices by providing functions such as data wipe and jailbreak/root detection. Data wipe allows the remote erasure of sensitive information from lost devices, preventing unauthorized access. Jailbreak/root detection helps identify compromised devices that may bypass standard security measures, ensuring that they do not access network resources.


Question No. 5

A customer requires wireless traffic from the branch to be routed through the firewall at corporate headquarters. A RADIUS server is in each branch location. Which Cisco FlexConnect configuration must be used?

Show Answer Hide Answer
Correct Answer: B

To route wireless traffic from the branch through the firewall at corporate headquarters, the correct Cisco FlexConnect configuration iscentral authentication and central switching. This setup ensures that both user authentication and data traffic are handled centrally at the corporate headquarters, allowing the firewall to inspect and route the traffic accordingly. Local RADIUS servers in each branch can still be used for redundancy or other purposes, but the central control of traffic is maintained.Reference: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide.
