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?
A . VLAN 20 must have GRE enabled on it.
B . VLAN 20 cannot have an IP address.
C . VLAN 20 must have an IP address in the same subnet as the controller.
D . VLAN 20 must not enable jumbo frames.

What is a reason to implement PIM-DM as opposed to PIM-SM?
A . to control exactly which multicast groups are routed through the network
B . to permit a higher density of RP routers in the network core
C . to conserve bandwidth over WAN links
D . to use on high-bandwidth routed connections

Which benefit is provided by MD5 authentication for BGP?
A . It validates that BGP messages arrive from an authorized device.
B . It verifies that received BGP routes have valid next hop IP addresses.
C . It enables users to authenticate to a server across BGP AS boundaries.
D . It protects BGP routing information from eavesdroppers.

Switch-1 and Switch-2 connect on interface A23. The switches experience a connectivity issue. The network administrator sees that both switches show this interface as up. The administrator sees the output shown in the exhibit on Switch-1.

What is a typical issue that could cause this output?
A . asymmetric routing introduced by a routing protocol
B . an issue with VLAN mismatch
C . mismatched subnet mask on the VLAN for the link
D . a jumbo frame mismatch

Answer: A

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

Answer: A

Refer to the exhibits.

Exhibit 1

Exhibit 2

Switch-1 has a power issue that causes it to fail. When Switch-1 comes back up, endpoints lose connectivity for a few minutes. The network administrator decides to enter this command on Switch-1:

Switch-1 (config)# vlan 10 vrrp vrid 10 preempt-delay-time 120

Exhibit 2 shows the VRRP configuration just after the change.

What is the effect of this change?
A . Switch-1 and Switch-2 both become Master in their own VRRP virtual router due to the delay timer mismatch. The mismatch must be fixed.
B . Switch-1 now waits to take over as Master if it fails and recovers. This should prevent the connectivity issue from occurring again.
C . Switch-1 experiences an internal error in the VRRP process. This error causes Switch-2 to take over as Master for VLAN 2.
D . Switch-1 continues to act as it did before the preempt delay time was set. Administrators must plan additional changes to fix the issue.

Answer: C

Refer to the exhibits.

Exhibit 1

Exhibit 2

Exhibit 1 shows the topology for the network. The network administrator sees the log entries shown in Exhibit 2.

Which type of failure is indicated?
A . A link between Switch-1 and Switch-2 went down. BFD detected the lost connectivity and behaved as expected.
B . Graceful restart helper was not enabled on Switch-2, so BFD was unable to operate correctly, and the session was taken down.
C . A hardware issue caused a unidirectional link; BFD detected the issue at Layer 2 and prevented a broadcast storm.
D . BFD was set up incorrectly on Switch-2, so it caused Switch-2 to lose adjacency with Switch-1 rather than repair the session.

Answer: D

The implementation plan for AOS-Switches calls for them to implement port-based tunneled node. The Aruba Mobility Controllers that will support the AOS-Switches run software 8.1. The controllers will also support APs, are managed by Mobility Master, and use clustering.

Which issue with this plan needs to be addressed?
A . The controllers cannot support tunneled node with AOS-Switches when they are managed by the Mobility Master.
B . The switches cannot connect to controllers that also support APs.
C . The controllers must have their software updated before they can support the switches.
D . The switches must use role-based tunneled node to work with clustering controllers.

Refer to the exhibit.

The routing switches shown in the exhibit run OSPF on the links between each other. The commander in the Switch-1 VSF fabric goes down. Traffic is disrupted for several seconds.

What should a network administrator do to support a faster failover in a similar situation?
A . Configure echo mode BFD on the VLAN that connects Switch-1 and Switch-2.
B . Add VRRP on the VLAN between Switch-1 and Switch-2.
C . Configure graceful restart, or nonstop OSPF, on Switch-1 and Switch-2, with a proper timer.
D . Create a redundant virtual link between Switch-1 and Switch-2.

Refer to the exhibits.

Exhibit 1

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 . Due to changes at ISP 1, Switch-1 now selects a different best route.
D . An administrator has applied a route map on Switch-1 that filters advertised routes.
