A network administrator deploys DSCP based prioritization in the entire wired network to improve voice quality for a SIP-based IP telephony system used by the company. However, users report that calls they make from WLAN have poor audio quality, while desktop phones do not experience the same problem. The network administrator makes a test call and looks in the datapath session table.
Based on the output shown in the exhibit, what is one area that the network administrator should focus on?

• A. Dynamic Multicast Rate Optimization
• B. UCC based DSCP correction
• C. WMM support on the WLAN
• D. wired network congestion

Refer to the exhibits.


A network administrator deploys User Based Tunneling (UBT) in a corporate network to unify the security policies enforcement. When users authenticate with 802.1X, ClearPass shows Accept results, and sends the Aruba-User-Role attribute as expected. However, the AOS-CX based switch does not seem to build the tunnel to the Mobility Controller (MC) for this user.
Why does the switch fail to run UBT for the user?

• A. The switch has not fully associated to the MC.
• B. The switch is not configured with the port-access role.
• C. ClearPass is sending the wrong Vendor ID.
• D. ClearPass is sending the wrong VSA type.
• E. The switch is not configured with the gateway-role.

A network administrator wants to receive a warning level alarm every time the noise floor rises above -82 dBm on any of the AP radios.
Which alarm definition must the network administrator create to accomplish this?

Refer to the exhibit.

A network administrator wants to configure an 802.1x supplicant for a wireless network that includes the following:
* AES encryption
* EAP-MSCHAP v2-based user and machine authentication
* Validation of server certificate in Microsoft Windows 10
The network administrator creates a WLAN profile and selects the change connection settings option. Then the network administrator changes the security type to Microsoft: Protected EAP (PEAP), and enables user and machine authentication under Additional Settings.
What must the network administrator do next to accomplish the task?

• A. Enable server certificate validation under Settings.
• B. Enable user authentication under Settings
• C. Change default RC4 encryption for AES.
• D. Change the security type to Microsoft: Smart Card or other certificate.

An organization wants to deploy a WLAN infrastructure that provides connectivity to these client categories:
* Employees
* Contractors
* Guest users
* Corporate IoT legacy devices that support no authentication or encryption Employees and contractors must authenticate with company credentials and get network access based on AD group membership. Guest users are required to authenticate with captive portal using predefined credentials. Only employees will run L2 encryption.
Which implementation plan fulfills the requirements while maximizing the channel usage?

• A. Create VAP1 to run WPA2-AES and 802.1x authentication. VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal.
• B. Create VAP1 to run WPA2-AES and 802.1x authentication, and VAP2 to run opensystem encryption with MAC authentication and captive portal.
• C. Create VAP1 to run WPA2-AES and 802.1x authentication. VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal and L2 fail through.
• D. Create a single VAPto run WPA2-AES and 802.1x authentication. MAC authentication L2 fail through, captive portal, and VIA support.
