Two PCs are attached to a hub, which is attached to port ge-0/0/0 on your EX Series switch. You must separate the incoming traffic from the PCs into two VLANs.

What should you use to accomplish this task?

  1. dynamic VLAN registration with MVRP

  2. private VLAN

  3. filter-based VLAN

  4. guest VLAN

You are the administrator for the network shown in the exhibit. R1 receives the 196.15.4.0/24 route from routers R2, R3, and R4. Local preference values have not been modified in this network. You are asked to ensure that R1 prefers the path through AS 3149 for traffic destined to 196.15.4.0/24.

Which two methods will accomplish this task? (Choose two.)

  1. Configure a lower local preference on R3.

  2. Configure as-path-prepend on R2 and R4.

  3. Configure local-as on R3.

  4. Configure always-compare-med on R1.

Answer: B,D

Question No: 75 – (Topic 2)

Your company recently implemented Layer 2 authentication and access control to secure users accessing the corporate network. You implemented 802.1X, MAC RADIUS, and a captive portal to support a variety of hosts on the network. Senior management is concerned that valid users might be authenticated incorrectly on the network and they ask you questions about how these different access technologies are used simultaneously.

Which three statements are correct? (Choose three.)

  1. MAC addresses that are part of a MAC address whitelist or a static MAC list are authenticated before any other authentication protocol is invoked.

  2. Captive portal is a supported fallback option for 802.1X.

  3. If the authentication server fails to respond to access requests and both a server-fail and guest VLAN are configured correctly, the server-fail VLAN takes precedence over the guest VLAN.

  4. Captive portal can only be configured on Layer 3 interfaces.

  5. If a port is configured with 802.1X and the host does not respond to EAP requests, no other authentication protocol can authenticate the host.
