Question # 4

Users run Skype for Business on wireless clients with no WMM support over an Aruba Mobility Master (MM) - Mobility Controller (MC) based network. When traffic arrives at the wired network, it does not include either L2 or L3 markings.

Which configuration steps should the network administrator take to classify and mark voice and video traffic with UCC heuristics mode?

A.

Enable WMM in a VAP profile, and explicitly permit voice and video UDP ports in a firewall policy.

B.

Confirm OpenFlow is enabled in the user role and VAP profile. Then enable WMM in a SSID profile, and explicitly permit voice and video UDP ports in a firewall policy.

C.

Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.

D.

Confirm MM is the Openflow controller of MCs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.

Question # 5

Refer to the exhibit:

A company acquires ten barcode scanners to run inventory tasks. These WiFi devices support WPA2-PSK security only. The network administrator deploys a WLAN named scanners using the configuration shown in the exhibit.

What must the network administrator do next to ensure that the scanner devices successfully connect to their SSID?

A.

Set internal as the MAC authentication server group.

B.

Add scanner MAC addresses in user derivation rules.

C.

Enable L2 Authentication Fail Through.

D.

Add scanner MAC addresses in the internal database.

Question # 6

A network administrator has racked up a 7210 Mobility Controller (MC) that will be terminating 200+ Aps on a medium-size branch office. Next, the technician cabled the appliance with 4SPF+ Direct Attached Cables (DACs) distributed between two-member switching stack and powered it up.

What must the administrator do next in the MCs to assure maximum wired bandwidth utilization?

A.

Map the four physical ports to port channel 0.

B.

Disable spanning tree and allocate unique VLANs to each port.

C.

Manually set 10Gbps speeds on all ports.

D.

Configure the same MSTP region that the switches have.

E.

Make all ports trunk interfaces and permit data VLANs.

Question # 7

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

Question # 8

Refer to the exhibits.

A user reports slow response time to a network administrator and suggests that there might be a problem with the WLAN. The user’s phone supports 802.11ac in the 5 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.

The low SNR forces the client to back off to low MCs. therefore speed is low and retransmits are high.

B.

Client health is poor, but SNR is fair. TX power must be increased in both the client and the AP.

C.

Since SNR is good, then the high retransmit rate must be due a hidden node scenario or high interference.

D.

High Successful frame count and high Max Speed is an indication of a healthy client. Connection will improve at anytime.
