NEW QUESTION 6
A company plans to deploy a Mobility Master (MM). The MM will manage 50 Mobility Controller (MC) appliances that will control a total of 680 APs, and 10 Virtual Mobility Controllers (VMCs) that will control a total of 160 APs.
How many MM licenses does the company require?

• A. 60
• B. 210
• C. 900
• D. 960

Answer: C

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.

Answer: B

NEW QUESTION 10
A network administrator wants to implement MAC filtering for the wireless network of a local financial firm to ensure that only employees can access the wireless network. What is a potential weakness of this solution?

• B. Authorized MAC addresses are visible in plaintext in the air and can be easily spoofed.
• C. Many popular clients do not have the capability to connect to WLANs that use MAC filters.
• D. MAC filters offer no protection against authorized users who try to connect unauthorized devices.

Answer: B

NEW QUESTION 11
