Question 1

An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure.

The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment.

What must the network administrator do so the network consultant can successfully deploy the solution? (Choose two.)

AAllocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another IP address for its gateway.

BAllocate VLAN20 to the second server, and permit routing between them, then reserve one IP address for the second MM and another IP address for its gateway.

CConfigure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.

DAllocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another for the VIP.

EConfigure an ACL entry that permits UDP 500, TCP 4500, and multicast IP 224.0.0.5.

Answer : A, E

Question 2

A network administrator assists with the migration of a WLAN from a third-party vendor to Aruba in different locations throughout the country. In order to manage the solution from a central point, the network administrator decides to deploy redundant Mobility Masters (MMs) in a datacenter that are reachable through the Internet.

Since not all locations own public IP addresses, the security team is not able to configure strict firewall polices at the datacenter without disrupting some MM to Mobility Controller (MC) communications. They are also concerned about exposing the MMs to unauthorized inbound connection attempts.

What should the network administrator do to ensure the solution is functional and secure?

ADeploy an MC at the datacenter as a VPN concentrator.

BBlock all inbound connections, and instruct the MM to initiate the connection to the MCs.

CBlock all ports to the MMs except UDP 500 and 4500.

DInstall a PEFV license, and configure firewall policies that protect the MM.

Answer : C

Question 3

Refer to the exhibits.

Exhibit 2

Exhibit 3

Exhibit 4

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?

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

BClearPass.23 is the authentication server, and MC2 is the captive portal server.

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

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

Answer : A

Question 4

An Aruba Mobility Master (MM) - Mobility Controller (MC) solution is connected to a wired network that is ready to prioritize DSCP marked traffic. A group of WMM-enabled clients sends traffic marked at L2 only.

What must the network administrator do to map those markings to DSCP equivalent values when traffic is received by the APs?

AEnable WMM in the SSID profile.

BEnable WMM in the VAP profile.

CEnable Skype4Business ALG Support.

DEnable traffic to be marked with session ACLs.

Answer : B

Question 5

Users run encrypted Skype for Business traffic with no WMM support over an Aruba Mobility Master (MM) - Mobility Controller (MC) based network. When voice, video, and application sharing traffic arrive at the wired side of the network, all the flows look alike due to the lack of L2 and L3 markings

How can the network administrator identify these flows and mark QoS accordingly?

AConfirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable WMM in a VAP profile.

BUse a media firewall policy that match these three flows, and use permit and TOS actions with 56, 40, and 34 values for voice, video, and application sharing, respectively Then enable the Skype4Business ALG in the UCC profiles.

CConfirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable the Skype4Business ALG in the UCC profiles.

DConfirm the MM is the Openflow controller of the MCs and Openflow is enabled in VAP and the firewall roles. Then integrate the MM with the Skype4Business SDN API. and enable the Skype4Business ALG in the UCC profiles.

Answer : D

Question 6

Refer to the exhibits.

Exhibit 1

Exhibit 2

Exhibit 3

A network administrator wants to allow contractors to access the corporate WLAN named EmployeesNet with the contractor role in VLAN 40. When users connect, they do not seem to get an IP address. After some verification checks, the network administrator confirms the DHCP server (10.254.1.21) is reachable from the Mobility Controller (MC) and obtains the outputs shown in the exhibits.

What should the network administrator do next to troubleshoot this problem?

APermit UDP67 to the contractor role.

BRemove the IP address in VLAN 40.

CConfigure the DHCP helper address.

DConfirm there is an IP pool for VLAN 40.

Answer : A

Question 7

A software development company has 764 employees who work from home. The company also has small offices located in different cities throughout the world. During working hours, they use RAPs to connect to a datacenter to upload software code as well as interact with databases.

In the past two month, cabling issues have occurred connection to the 7240XM Mobility Controller (MC) that runs ArubaOS 8 and terminates the RAPs. These RAPs disconnect, affecting the users connected to the RAPs. This also causes problems with code uploads and database synchronizations. Therefore, the company decides to add a second 7240XM controller for redundancy.

How should the network administrator deploy both controllers in order to provide the redundancy while preventing failover events from disconnecting users?

AConnect both controllers with common VLANs. and create an HA fast failover group with public addresses in the internet VLAN.

BConnect both controllers with common VLANs. and create an L2-connected cluster using public addresses in the internet VLAN.

CConnect both controllers with different VLANs. and create an L2-connected cluster using public addresses in the internet VLAN.

DConnect both controllers with common VLANs. and configure LMS/BLMS values equal to public addresses in the internet VLAN.
