• Question 37:

  Which IEEE standard provides the highest transmission rates in the 2.4GHz frequency band?

  A. 802.11a

  B. 802.11ac

  C. 802.11g

  D. 802.11n

  Correct Answer: D

• Question 38:

  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

  Correct Answer: C

  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.

• Question 39:

  A network administrator reduces an AP radio transmit power from 18 dBm to 15 dBm. This is a loss of 3

  dBms.

  What is the current power as a percentage of the original power?

  A. 10%

  B. 33%

  C. 50%

  D. 83%

  Correct Answer: C

• Question 40:

  Refer to the exhibit.

  

  A company has a Mobility Master (MM)-based solution with a guest WLAN. During the captive portal

  redirection, users who access a non-HTTPS Website see the error shown in the exhibit.

  How can a network administrator prevent this error?

  A. Enable automatic CPSec certificate deployment.

  B. Replace the default Mobility Master certificate with a certificate that has the correct hostname.

  C. Replace the default server certificate for mobility controllers with a certificate signed by a trusted CA.

  D. Reconfigure the guest WLAN to use EAP methods that rely on passwords rather than certificates.

  Correct Answer: C
