HPE6-A79 Online Practice Questions and Answers

A network administrator is in charge of a Mobility Master (MM) ?Mobility Controller (MC) based WLAN. The administrator has deployed an Airwave Management Platform (AMP) server in order to improve the monitoring capabilities and

generate reports and alerts.

The administrator has configured SNMPv3 and Admin credentials on both the MMs and MCs and has created Groups and Folders in the AMP server.

What two additional steps must the administrator do in order to let Airwave monitor the network devices? (Choose two.)

A. Manually add the Active MM and wait for automatic Discovery.

B. Map the AMP's IP address with a mgmt-config profile in the MM.

C. Set the AMP's IP address and Org string as DHCP option 43.

D. Manually add each MM, MC and Access Point in the AMP server.

E. Move "New" devices into a group and folder in Airwave.

Refer to the exhibit.

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. UCC based DSCP correction

B. WMM support on the WLAN

C. Dynamic Multicast Rate Optimization

D. wired network congestion

Refer to the exhibit.

Based on the output shown in the exhibit, which wireless connection phase has just completed?

A. L3 authentication and encryption

B. MAC Authentication and 4-way handshake

C. 802.11 enhanced open association

D. L2 authentication and encryption

Refer to the exhibits. Exhibit 1

Exhibit 2 Exhibit 3

A captive portal-based solution is deployed in a Mobility Master (MM) - Mobility Controller (MC) network. A wireless station connects to the network and attempts the authentication process. The outputs are shown in the exhibits. Which names correlate with the authentication and captive portal servers?

A. ClearPass.23 is the authentication server, and cp.mycompany.com is the captive portal server.

B. ClearPass.23 is the authentication server, and MC2 is the captive portal server.

C. Internal database in MC2 is the authentication server, and cp.mycompany.com is the captive portal server.

D. cp.mycompany.com is the authentication server, and ClearPass.23 is the captive portal server.

Refer to the exhibit.

An Aruba network is deployed with L2 and L3 Mobility Master (MM) redundancy across two datacenters, as shown in the exhibit. The network administrator confirms that all Mobility Controllers (MC) are currently communicating with MM1, which is the L2 Active and, L3 Primary.

Which MM IP will MCs communicate with if MM1 fails?

A. 10.1.1.10

B. 10.1.1.12

C. 10.2.1.10

D. 10.2.1.21

An Aruba WiFi solution for a football stadium includes 2500 APs, two Mobility Masters (MM), and eight Mobility Controllers (MCs). Key requirements are seamless roaming and even distribution of APs and clients, even during a MC failure. Which MC's deployment option offers seamless roaming, and even AP client distribution among all MCs before and after a MC failure?

A. a two-member HA group in dual mode

B. an eight-member L2-connected cluster

C. two four-member L2-connected clusters

D. an eight-member HA group in dual mode

Refer to the exhibits.

A user reports slow connectivity to a network administrator when connecting to AP-Garden and suggests that there might be a problem with the WLAN. The user's device supports 802.11n in the 2.4 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit.

What can the network administrator conclude after analyzing the data?

A. 2.4Ghz band is currently congested, therefore a NIC upgrade to 802.11ac or higher is recommended so the user can move to 5Ghz.

B. Channel usage is high and though this device has high speed the overall client rate is low on AP-Garden, there could be a few clients monopolizing the airtime on both bands at low speeds.

C. User's SNR value over time is lower than recommended, therefore he should either get closer to the Access Point or increase the transmit power.

D. 365s are low cost outdoor APs recommended for coverage design only. AP-Garden currently has more clients than recommended and is getting congested.

A network administrator has updated the ArubaOS code of a standalone Mobility Controller (MC) that is used for User-Based Tunneling (UBT) to a newer early release. Ever since the MC seems to reject PAPI sessions from the switch with the 10.1.10.10 IP address. Also the controller's prompt is now followed by a star mark: "(MC_VA) [mynode] *#"

When opening a support ticket, an Aruba TAC engineer asks the administrator to gather the crash logs and if possible replicate UBT connection attempts from the switch while running packet captures of PAPI traffic on the controller and obtain the PCAP files. The administrator has a PC with Wireshark and TFTP server using the 10.0.20.20 IP address.

What commands must the administrator issue to accomplish these requests? (Choose two.)

A. Option A

B. Option B

C. Option C

D. Option D

E. Option E

Refer to the exhibit.

A network administrator has recently enabled WMM on the VAP's SSID profile and enabled UCC Skype4B ALG at the Mobility Master level. During testing, some voice and video conference calls were made, and it was concluded that the call quality has dramatically improved. However, end to end information isn't displayed in the call's details. Also, Skype4B app-sharing's performance is poor at times.

What must the administrator do next in order to enable end to end call visibility and QoS correction to app-sharing service?

A. Deploy the SDN API Software in the Skype4B Solution and point to the MM.

B. Increase the app-sharing DSCP value in the Skype4B ALG profile.

C. Enable UCC monitoring on the "default-controller" mgmt.-server profile.

D. Enable the App-sharing ALG profile at both MM and MD hierarchy levels.

Refer to the exhibit.

A network administrator is evaluating a deployment to validate that a user is assigned the proper role and reviews the output in the exhibit. How is the role assigned to user?

A. The MC assigned the role based on Aruba VSAs.

B. The MC assigned the machine authentication default user role.

C. The MC assigned the default role based on the authentication method.

D. The MC assigned the role based on server derivation rules.
