Question 1 of 110

Refer to the exhibit.

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?

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.

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.

Clear interface statistics on the switches. Then, run the application and check the interface queue statistics for the switch-to-switch links.

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.

Correct Answer: C

To verify if the network infrastructure is prioritizing traffic correctly, the administrator should check the interface queue statistics on the switches involved. By clearing the interface statistics, running the application, and then examining the interface queue statistics for the switch-to-switch links, the administrator can determine if the packets are being prioritized in the appropriate queues. This provides direct evidence of how the traffic is being handled along the entire path between Device 1 and Device 2.

Question 2 of 110

Refer to the exhibits.

Exhibit 1.

Exhibit 2.

The exhibits show the current operational state for routes on Switch-3. The company wants Switch-3 to prefer the link to Switch-1 over the link to Switch-2 for all intra-area, inter-area, and external traffic.

What can the network administrator do to achieve this goal?

Set the OSPF cost on VLAN 108 higher than 1 on Switch-2 and Switch-3.

Set the OSPF administrative distance on Switch-2 higher than 110.

Set the OSPF area type to normal on all of the switches in Area 1.

Set the cost in the OSPF Area 1 stub command higher than 1 on Switch-2.

Correct Answer: A

To ensure Switch-3 prefers the link to Switch-1 over the link to Switch-2 for intra-area, inter-area, and external traffic, the network administrator should adjust the OSPF cost on the relevant VLANs. Setting the OSPF cost on VLAN 108 higher than 1 on Switch-2 and Switch-3 will increase the cost associated with the route through Switch-2. This change will make the route through Switch-1 the preferred path, as OSPF will select the route with the lower cost.

Question 3 of 110

Refer to the exhibit.

A network administrator needs to deploy AOS-Switches that implement port-based tunneled node. Their Aruba controller has IP address 10.1.10.5/24. The architect has assigned tunneled-node endpoints to VLAN 20.

What is one issue with the current configuration planned for VLAN 20 on the switch?

VLAN 20 must have GRE enabled on it.

VLAN 20 cannot have an IP address.

VLAN 20 must have an IP address in the same subnet as the controller.

VLAN 20 must not enable jumbo frames.

Correct Answer: B

For port-based tunneled node configurations, VLANs assigned to support tunneled-node endpoints typically do not have an IP address configured. This is because the VLAN is used to handle traffic that is tunneled to an Aruba controller, which means the IP addressing is managed by the controller, not the switch itself. Hence, VLAN 20 should not have an IP address.

Question 4 of 110

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?

The ABRs create a discontinuous area and disrupt intra-area routing between devices within Area 1.

The ABR core would send Area 1 traffic destined to the other switch through an access switch.

The ABRs lose adjacency entirely and cannot route traffic between each other at all.

The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.

Correct Answer: D

When there is a range mismatch between two ABRs in OSPF, they can lose adjacency within the area where the mismatch occurs. As a result, the ABRs must route all traffic to each other through the backbone area, which is Area 0 in OSPF. This situation does not create a discontinuous area or disrupted intra-area routing but rather forces traffic to follow a less efficient path, impacting overall routing efficiency.

Question 5 of 110

Refer to the exhibits.

Exhibit 1.

Exhibit 2.

The company wants to minimize congestion on Link 1.

Which spanning tree implementation meets this goal?

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

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

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

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

Correct Answer: B

To minimize congestion on Link 1, switch-to-switch traffic should be evenly distributed across the switches. By assigning Switch 2 as the root for VLANs 4 and 6, and Switch 3 as the root for VLANs 5 and 7 (as detailed in Option B), traffic will be better balanced. This ensures that no single link is disproportionately utilized, thereby minimizing congestion on Link 1.
