質問 1

Refer to the exhibits.
Exhibit 1

Exhibit 2

In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.
A network administrator needs to deploy AOS-Switches that use port-based tunneled node. The plan calls for tunneled-node endpoints to be assigned to VLAN 20 and for the Aruba Mobility Controller to handle the tunneled-node traffic at Layer 2. Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?

（A）D

（B）B

（C）C

（D）A

質問 2

Refer to the exhibits.

The network administrator enters the commands shown in Exhibit 2, and Switch-1 and Switch-2 exchange keepalive messages. What is the expected behavior if Switch-1 later fails to receive keepalive messages from Switch-2?

（A）After two consecutive missed keep-alive packets, Switch-1 sends SNMP traps, and Link 1 stays up until the issue is fixed.

（B）Switch-1 disables interface 1 for 10 seconds and then re-enables it. The interface continues to be re-enabled and disabled every 10 seconds until the issue is fixed.

（C）Switch-1 disables interface 1 for 10 seconds, and then re-enables it. The same process repeats twice. If the issue persists, the switch disables the interface permanently.

（D）After two consecutive missed keep-alive packets, Switch-1 disables interface 1, and the interface stays disabled until the issue is fixed.

質問 3

Refer to the exhibits.
Exhibit 1

Exhibit 2

Exhibit 2 shows IGMP groups on Switch-2, which runs IGMP but not PIM. Switch-1 and Switch-3 do not have IGMP or PIM enabled. Client 1 begins to forward multicasts to 239.1.1.1.
Which clients receive the multicasts?

（A）Client 2, but not any of the other clients

（B）Client 2, Client 3, and Client 4

（C）Client 3 and Client 4, but not Client 2

（D）Client 3, but not any of the other clients

質問 4

Refer to the exhibit.

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.

質問 5

Refer to the exhibit.

The routing switches shown in the exhibit use OSPF, and all of their interfaces are in Area 1. A faulty link on Switch-1 went up and down many times over the course of several hours. This caused link state updates (LSUs) to flood all of the routing devices in the OSPF AS and reduce performance. The network administrator fixed the faulty link on Switch-1, but the administrator also wants to mitigate the effects if a similar issue occurs in the future.
Which design improvement would help?

（A）Decrease the LSA generation timer, and make sure to set the same value on all routers

（B）Configure Area 1 as a stub area on all routers except Switch-2, Switch-3, and Switch-4

（C）Divide the AS into different areas, and aggregate routes between them

（D）Divide the AS into different areas, and configure the backbone area as an NSSA

質問 6

An AOS-Switch needs to implement tunneled node in role-based mode. Aruba ClearPass is configured to assign users for which the traffic should be tunneled to a role named tunnel. The Aruba Mobility Controller should apply policies associated with the employees group to these users.
What is the correct user role configuration on the AOS-Switch for this scenario?

（A）one user role named employees with tunnel set as the secondary role in the tunneled-node-redirect command

（B）two user roles, one named tunnel that uses the tunneled-node-redirect command, and one named employees

（C）two user roles, one named employees that uses the tunneled-node-redirect command, and one named tunnel

（D）one user role named tunnel with employees set as the secondary role in the tunneled-node-redirect command

質問 7

Refer to the exhibit.

The network administrator wants to summarize routes as much as possible in between areas. What is the correct range to specify for the router OSPF Area 2 command on Switch-2?

（A）10.0.0.0/21

（B）10.0.8.0/21

（C）10.0.16.0/21

（D）10.0.0.0/20

質問 8

Refer to the exhibits.
Exhibit 1

Exhibit 2

A company does not require authentication for security, but AOS-Switches are set up to use local MAC authentication (LMA) to assign the correct VLAN and priority to IP phones. IP phones and computers belong to different VLANs. Each device is supposed to connect to a specific port, but sometimes users connect their devices to the wrong ports and cannot receive access without help from IT.
How can a network administrator configure the switches to eliminate this issue?

（A）Add the MAC addresses for computers to the myPhones MAC group.

（B）Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.

（C）Create a user role that applies the user VLAN, and set this role as the initial role.

（D）Set the address limit to 2 on the switch ports that apply LMA.

質問 9

Refer to the exhibit.

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）an issue with VLAN mismatch

（B）mismatched subnet mask on the VLAN for the link

（C）a jumbo frame mismatch

（D）asymmetric routing introduced by a routing protocol

質問 10

A network administrator enters this command on an AOS-Switch:
Switch(config)# radius-server host 10.1.3.3 time-window 60
Which behavior will the switch show?

（A）It will wait one minute for a response from the RADIUS server before it sends another message

（B）It will reject RADIUS server change of authorization (CoA) messages with timestamps that are more than one minute old

（C）It will maintain idle user sessions for one minute before it re-authenticates the user to the RADIUS server

（D）It will give supplicants up to one minute to respond to RADIUS challenges before it considers authentication failed
