Exhibit 2

Exhibit 1 shows a portion of the BGP routing table when the BGP solution was first deployed. Exhibit 2 shows the same portion at the current time. What can explain the current state?

• A.Due to changes in the private network, Switch-1 can no longer reach 192.168.2.1.
• B.Switch-1 can no longer reach ISP 1 at 192.168.1.1.
• C.An administrator has applied a route map on Switch-1 that filters advertised routes.
• D.Due to changes at ISP 1, Switch-1 now selects a different best route.

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

• A.The switch is authorized in AirWave, which has the correct credentials to log in as a CLI manager.
• B.The switch specifies the AirWave IP address for the RADIUS server used for Telnet and SSH authentication.
• C.The switch defines the AirWave IP address in its zero touch provisioning (ZTP) profile.
• D.The switch is set to Manage Read-Write mode in AirWave but is not set to Monitor Only + Firmware Updates.

A company wants to change Area 1 shown in the exhibit from a stub area to a totally stub area.
What will be one effect of this planned change?

• A.Endpoints within Area 1 will no longer be able to reach endpoints in other areas.
• B.Switch-1 and Switch-2 will adjust the cost with which they advertise area 1 traffic in the backbone.
• C.Routing devices within Area 0 will temporarily lose adjacency with each other.
• D.Some traffic from Area 1 to other areas will no longer follow the lowest cost path.

A network administrator sets up prioritization for an application that runs between Device 1 and Device 2. However, the QoS for the application is not what the administrator expects.
How can the administrator check if the network infrastructure prioritizes traffic from Device 1 and Device 2?

• A.Run a packet capture on Device 2, run the application, and look in the packet capture for a high value DSCP in the IP header.
• B.Clear interface statistics on the switches. Then, run the application and check the interface queue statistics for the switch-to-switch links.
• C.Set up RMON alarms on the switches that trigger when a high number of packets are dropped. Then, run the application and check for the alarm.
• D.Run a packet capture on Device 1, run the application, and look in the packet capture for a high value DSCP in the IP header.

OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is not configured with a range for Area 1.
Which type of issue occurs due to this mismatch?

• A.The ABRs lose adjacency entirely and cannot route traffic between each other at all.
• B.The ABRs create a discontinuous area and disrupt intra-area routing between devices within Area 1.
• C.The ABR core would send Area 1 traffic destined to the other switch through an access switch.
• D.The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.
