• Question 11:

  Refer to the exhibits.

  Exhibit 1

  

  Exhibit 2

  

  Traffic between servers in Area 1 takes a sub-optimal path rather than the link dedicated to VLAN 1000, subnet 10.0.0.0/30. Based on the exhibits, what can administrators do to create a better path for this traffic?

  A. Decrease the OSPF cost on the VLAN 1000 interface on Switch-1 and Switch-2.

  B. Add a virtual OSPF link between Switch-1 and Switch-2.

  C. Add a VLAN in OSPF Area 1 on the link between Switch-1 and Switch-2.

  D. Make sure that OSPF is enabled in Area 0 on VLAN 1000 on both Switch-1 and Switch-2.

  Correct Answer: C

• Question 12:

  An AOS-Switch enforces 802.1X authentication to an Aruba ClearPass server. A user connects but cannot receive network access, even though the ClearPass administrator finds an Access-Accept for the user on this switch. The switch administrator suspects that there is an issue with the dynamic settings returned by ClearPass.

  Where should the administrator look for information about these settings?

  A. in the details for port-access clients

  B. in the detailed RADIUS server statistics

  C. in the interface statistics

  D. in the running-config for the interface

  Correct Answer: A

• Question 13:

  What is a primary use case for RPVST+ on AOS-Switches?

  A. more granular load balancing than MSTP when access switches connect to two core switches

  B. enhanced loop protection in an MSTP network

  C. integration of AOS-Switches in a heterogeneous vendor network that uses the Cisco protocol

  D. seamless integration with RSTP

  Correct Answer: C

• Question 14:

  Which solution allows administrators to monitor link status and port utilization on AOS-Switches from a centralized location?

  A. Aruba Mobility Controller

  B. Aruba AirWave

  C. Aruba Mobility Manager

  D. Aruba ClearPass

  Correct Answer: B

• Question 15:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  The company wants to minimize congestion on Link 1. Which spanning tree implementation meets this goal?

  A. Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

  B. Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

  C. Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

  D. Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7 Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1 Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

  Correct Answer: C

• Question 16:

  A network administrator wants to use Aruba AirWave to audit an AOS-Switch configuration. What is one requirement?

  A. The switch defines the AirWave IP address in its zero touch provisioning (ZTP) profile.

  B. The switch specifies the AirWave IP address for the RADIUS server used for Telnet and SSH authentication.

  C. The switch is authorized in AirWave, which has the correct credentials to log in as a CLI manager.

  D. The switch is set to Manage Read-Write mode in AirWave but is not set to Monitor Only + Firmware Updates.

  Correct Answer: B

• Question 17:

  Refer to the exhibits: Exhibit 1

  

  Exhibit 2 A network administrator at a university notices high utilization on links between the access layer and core. The output shown in the exhibit is characteristic of samples taken several times an hour during congestion. The administrator suspects file sharing and other unauthorized traffic, and decides to use an ACL to permit only HTTP, HTTPS, and a few other authorized types of traffic.

  

  How can the administrator apply the ACL to address both the security and the congestion problem?

  A. as an inbound PACL on the link aggregations on the access switches

  B. as an inbound VACL on the student VLAN on Switch-1

  C. as an inbound PACL on the link aggregations on Switch-1

  D. as an inbound VACL on the student VLAN on the access switches

  Correct Answer: D

• Question 18:

  What is a reason to implement PIM-DM as opposed to PIM-SM?

  A. to conserve bandwidth over WAN links

  B. to permit a higher density of rendevous point (RP) routers in the network core

  C. to control exactly which multicast groups are routed through the network

  D. to obtain the simplest setup in a network with high bandwidth

  Correct Answer: D

• Question 19:

  Refer to the exhibit.

  

  A network administrator wants to prevent endpoints from spoofing the MAC address of the VLAN 2 default gateway. What should the administrator configure on Switch-1?

  A. MAC lockdown of the default gateway MAC address on ports 1-20

  B. MAC lockdown of the default gateway MAC address on trk1

  C. default gateway MAC address as a port security authorized address on trk1

  D. default gateway MAC address as a port security authorized address on ports 1-20

  Correct Answer: B

• Question 20:

  Which situation requires an AOS-Switch interface to support MAC-based VLANs?

  A. The interface has an extended MAC ACL applied to it in the outbound direction, and it uses VLAN ID as one of the criteria for rules.

  B. The interface has an extended MAC ACL applied to it in the inbound direction, and it has multiple tagged VLAN assignments.

  C. The interface is configured to support Local MAC Authentication (LMA), authenticates endpoints against a non-default MAC group, and limits the address count to 1.

  D. The interface is configured to support 802.1X in user-based mode, connects to more than one endpoint at a time, and users are assigned to different dynamic VLANs.

  Correct Answer: B
