NEW QUESTION 101
Two AOS-Switches are directly interconnected. The network administrator wants to prevent broadcast storms and other Layer 2 issues that could occur if there is physical damage to a cable.
Which technology should the administrator implement on the connected switch interfaces?

• A. MAC Lockdown
• B. Bidirectional Forwarding Detection (BFD)

Answer: D

 

NEW QUESTION 102
Refer to the exhibit.

An AOS-Switch has an extended ACL that is applied to several physical interfaces.
- New interfaces have been brought online.
- The ACL has been applied to them as well.
A network administrator sees the output in the exhibit and is concerned that the switch will reach the limit for rules.
What can the administrator do to address this concern?

• A. Resequence the ACL with less space in between the entries.
• B. Enable ACL grouping, and apply ACLs as shared ACLs.
• C. Remove static ACLs, and have the RADIUS server send dynamic ACLs.

NEW QUESTION 103
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. Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.
• B. Create a user role that applies the user VLAN, and set this role as the initial role.
• C. Set the address limit to 2 on the switch ports that apply LMA.
• D. Add the MAC addresses for computers to the myPhones MAC group.

Answer: A

Explanation:
Explanation
If you place the computer's MAC in that group, all traffic from the computer will get placed in the same class as the IP phones, which is not a good practice (Although it will technically work). (The only reason they are using LMA is the dynamically assign a VLAN/QoS priority to that device)
