  A. the connectivity between the AP that the client is associated to and the MC

  B. the firewall role and policy that apply to this user

  C. the certificate on the RADIUS server

  D. the connectivity between the Master Controller (MC) for the client and the RADIUS server

  Correct Answer: B

• Question 96:

  A. it provides more multi-user spatial streams.

  B. it provides more coverage in the horizontal direction than in the vertical direction.

  C. it provides more single-user spatial streams.

  D. it provides more coverage in both the horizontal and vertical directions.

  Correct Answer: B

• Question 97:

  A company has a single Aruba Mobility Master (MM)-based solution with two Mobility Controllers (MCs). Network administrators want APs in building 1 to support a WLAN but do not want APs in building 2 to support the WLAN.

  How can administrator ensure that they can enforce this rule as they set up the WLAN in the Mobility Master (MM) Interface?

  A. Place APs in different buildings in different AP Groups.

  B. Assign APs in different buildings to different MM nodes.

  C. Configure APs in different buildings to use different frequency bands.

  D. Assign different radio profiles to APs in different buildings.

• Question 98:

  What is one difference between captive portal authentication and 802.1X authentication?

  A. 802.1X authentication always authenticates the wireless client, while captive portal authentication always authenticates the wireless user.

  B. 802.1X authentication occurs at Layer 2, while captive portal authentication occurs at Layer 3.

  C. 802.1X authentication must use an LDAP server, while captive portal authentication can use a RADIUS server or an LDAP server.

  D. 802.1X authentication is typically implemented without encryption, while captive authentication is often combined with WPA or WPA2.

  Correct Answer: B

• Question 99:

  C. Transmit Power Control (TPC)

  D. QAM modulation

  Correct Answer: B

• Question 100:

  Refer to the exhibit.

  

  What describes the behavior for this WLAN?

  B. No APs broadcast the SSID. Clients cannot connect to the WLAN until administrators activate it.

  C. No APs broadcast the SSID. Clients can connect to the WLAN on APs in the default gorup only.

  D. APs in the default group broadcast the SSID. Clients can connect to the WLAN on APs in any group.

  Correct Answer: C
