In the design shown:

The BGP peering between agg-sw1 and agg-sw2 is being established using loopback interfaces as the BGP neighbor addresses (10.0.0.2 and 10.0.0.4)

When BGP peering uses loopbacks, you must configure the BGP session to originate updates from the same loopback interface that the neighbor’s address resolves to

Otherwise, the TCP session fails because:

The source IP does not match the configured neighbor remote-IP which is based on the loopback address

Aruba AOS-CX requirement:

“When configuring eBGP or iBGP neighbors using loopback interfaces, apply update-source under the IPv4 unicast address family so BGP uses the correct source interface for peering.”

In HPE Aruba ClearPass Guest configuration, the “Address” field defines the Fully Qualified Domain Name (FQDN) of the captive portal server that users are redirected to when accessing the guest network.

When a wildcard certificate is used, such as *.aruba-training.com, the derived FQDN for the captive portal redirection automatically becomes:

captiveportal-login.aruba-training.com

This naming convention is required so that the Common Name (CN) or Subject Alternative Name (SAN) in the SSL certificate matches the domain presented to the client browser during HTTPS redirection.

If the “Address” field is incorrectly configured with just aruba-training.com, the certificate and the redirection URL will not match, causing the browser to block or fail the authentication process. This results in users being unable to browse after pressing Connect on the portal page.

HPE Aruba documentation states:

“When using a wildcard certificate (for example CN = *.domain.com) on ClearPass Guest, the web login redirection address must be configured as captiveportal-login.domain.com to ensure the HTTPS certificate name matches the redirection hostname.”

“If the address field does not match the derived hostname of the certificate, browser trust validation fails and users cannot proceed beyond the captive portal page.”

Additionally, the ArubaOS and ClearPass Guest deployment guide clarifies that wildcard certificates are fully supported for guest portals, provided that the Address field follows the proper naming pattern.

Incorrect Configurations:

Setting “Address” to aruba-training.com causes SSL mismatch errors.

Leaving the “Address” blank defaults to a local IP or hostname mismatch.

Correct Configuration:

“Address” should be set to captiveportal-login.aruba-training.com when the wildcard certificate is *.aruba-training.com.

Option Explanations:

A. Incorrect – this does not follow the certificate’s derived FQDN format.

B. Correct – matches the expected derived FQDN for wildcard certificates.

C. Incorrect – HTTPS certificates are required for secure guest portals.

D. Incorrect – Wildcard certificates are supported by ClearPass Guest and ArubaOS.

Final Verified Answer: B

To address connectivity issues when students are working outdoors, increasing the transmission (TX) power range for the 5GHz radios can help improve signal strength and coverage. The setting shown indicates a conservative approach to power settings, which might not provide sufficient coverage for outdoor areas. By increasing the power range, you can extend the wireless signal reach, which aligns with best practices for outdoor wireless coverage.
