質問 54
Refer to the exhibits.
Exhibit 1
Exhibit 2
Network administrators use the Aruba Mobility Master (MM) wizard to create a WLAN and do not manually alter any of the profiles for that WLAN. The exhibits show some of the settings for the WLAN. Some wireless users cannot successfully connect to the WLAN. Network administrators attempt to connect on their own machines with a test account, and the connection is successful. They attempt to connect with the same account on user clients, and the connection fails.
Which issue could prevent authentication from completing correctly?
- A. The user clients have unauthorized MAC addresses, so the RADIUS server rejects the authentication even though the username and password are correct.
- B. The user clients do not trust the RADIUS server certificate and are configured not to prompt users to trust new certificates.
- C. Some access points (APs) are not configured as clients on the RADIUS server, so user clients connected to them cannot authenticate.
- D. The RADIUS server has reached the maximum number of RADIUS clients that it can support, so it rejects new wireless clients.
正解: B
質問 55

- A. Replace the default server certificate for mobility controllers with a certificate signed by a trusted CA.
- B. Reconfigure the guest WLAN to use EAP methods that rely on passwords rather than certificates.
- C. Replace the default Mobility Master certificate with a certificate that has the correct hostname.
- D. Enable automatic CPSec certificate deployment.

質問 58
A company plans to deploy a Mobility Master (MM). The MM will manage 50 Mobility Controller (MC) appliances that will control a total of 700 APs, and 10 Virtual Mobility Controllers (VMCs) that will control a total of 200 APs.
How many MM licenses does the company require?
- A. 0
- B. 1
- C. 2
- D. 3

解説:
Explanation
Starting with ArubaOS 8.0.1, the MM license is required to terminate devices (controllers or APs) on Mobility Master. If the Mobility Master does not have sufficient MM licenses and an AP fails to obtain a license, that AP can get an IP address and connect to its controller, but will not broadcast an SSID.
