A network administrator wants to add the protections of root guard to the network. Based on the spanning tree topology, on which ports should the network administrator implement root guard?

A. 3-24

B. 1 and 2

C. A1 and A2

D. 2 and A3

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

B. Create a user role that applies the user VLAN, and set this role as the initial role.

C. Add the MAC addresses for computers to the myPhones MAC group.

D. Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.

AOS-Switches authenticate guests to ClearPass with captive portal. An administrator notices that some guests are unable to reach the captive portal page.

What will resolve this issue?

A. Permit DNS on the ClearPass Portal

B. Permit DHCP on the ClearPass Portal.

C. Permit HTTP or HTTPS on the ClearPass Portal.

D. Permit Allow All MAC-Auth on the ClearPass Portal.

Refer to the exhibit.

Switch-2, Switch-5, and Switch-6 currently have many OSPF routes to Area 1 networks. The network administrator wants to replace these routes with a single aggregated route to 10.1.0.0/16 on each switch.

Where should the administrator specify the 10.1.0.0/16 range?

A. in the Switch-2 OSPF Area 2 configuration

B. in the Switch-1 OSPF Area 0 configuration

C. in the Switch-1 OSPF Area 1 configuration

D. in the Switch-2, Switch-5, and Switch-6 OSPF global configuration

Refer to the exhibit.

An AOS-Switch has the ACL shown in the exhibit. A network administrator then enters these commands: Switch(config)# mac-access-list standard myACL Switch(config-std-macl)# deny 007d.45cc.0000 0000.0000.ffff

How does this ACL treat these frames: 1 = 007d.45cc.ffff 2 = 007d.45cc.0000

A. It denies both frames.

B. It permits both frames.

C. It denies frame 1 and permits frame 2.

D. It permits frame 1 and denies frame 2.

Two 5400R AOS-Switches are OSPF neighbors. The network administrator wants routing to update as quickly as possible in the event of a failure on a neighboring switch.

Which technology should the administrator implement on the connected switch interfaces?

A. MAC Lockdown

B. Unidirectional Link Detection (UDLD)

C. Bidirectional Forwarding Detection (BFD)

D. Spanning Tree Root Guard

A network administrator needs to configure an AOS-Switch to classify traffic. Comparing QoS policy and global policy, what is one function that only a class-based QoS policy can fulfill?

A. Apply a DSCP to HTTP traffic from some sources but not other sources.

B. Apply a DSCP rather than an 802.1p value to classified traffic.

C. Override the incoming DSCP in the received traffic.

D. Override the DSCP or priority applied directly to an interface.

What is the purpose of the captive portal URL hash key on an AOS-Switch?

A. It specifies the captive portal URL and conceals the setting in the config.

B. It authenticates guest users based on the password the users enter in the portal.

C. It does not let users alter the URL that redirects them to the portal.

D. It encrypts and secures the RADIUS messages that the AOS-Switch sends to ClearPass.

Refer to the exhibit.

An administrator created a backplane stack with the plug-and-play method and did not after the default backplane stacking settings. Later, who backplane stacking links failed as shown in the exhibit. The network administrator then restored the failed links.

When the stack is reformed, which switches become commander and standby?

A. Member 4 remains commander, and Member 5 remains standby

B. Member 1 becomes commander, and Member 4 becomes standby

C. Member 4 remains commander, and Member 1 becomes standby

D. Member 1 becomes commander, and Member 2 becomes standby

Refer to the exhibit.

An AOS-Switch has the ACL shown in the exhibit. A network administrator then enters these commands: Switch(config)# mac-access-list standard myACL Switch(config-std-macl)# 25 deny 007d.45cc.0000 0000.0000.ffff

How does this ACL treat these frames: 1 = 007d.45cc.ffff 2 = 007d.45cc.0000

A. It denies both frames.

B. It permits both frames.

C. It denies frame 1 and permits frame 2.

D. It permits frame 1 and denies frame 2.
