A colleague recently implemented MSTP in your Layer 2 network and is having trouble determining why it is not working properly. You are asked to review the outputs provided in the exhibit to determine the cause.

Referring to the exhibit, what is causing the issue?

A. The region name is configured the same on both devices.

B. The VLAN mapping is configured incorrectly.

C. The MSTP revision is configured incorrectly.

D. The bridge priority has not been configured correctly.

You are asked to set up 802.1X port authentication for all access ports on your EX Series switch. You must ensure that only one user is allowed to authenticate per port and all other attempts are denied.

Which supplicant mode must be used?

A. single mode

B. single-secure mode

C. default mode

D. multiple mode

A network routes IPv4 traffic only. You want to add IPv6 to the network, but you must use a single IGP for both IPv4 and IPv6 traffic.

Which protocol meets this requirement?

A. OSPFv2

B. BGPv4

C. ES-ISv1

D. OSPFv3

You must configure your access switch with more than 3000 VLANs and you want the ability to load- balance across them.

Which spanning-tree approach has the least impact on control-plane performance?

A. Configure your access switch with a load-balancing policy and apply it under [edit protocols rstp].

B. Configure your access switch for Rapid-PVST+.

C. Configure your access switch for MSTP, incorporating the use of MSTIs.

D. Configure your access switch for both VSTP and RSTP.

A Layer 2 transparent firewall separates two OSPFv3 routers. For the two OSPFv3 routers to form an adjacency, which protocol must be permitted on the firewall?

A. IPv4 protocol 89

B. IPv6 protocol 89

C. TCP port 89

D. UDP port 89

You need to enable authentication for your multiarea OSPF network. In this scenario, which three statements are correct? (Choose three)

A. MDS and simple authentication types are mutually exclusive

B. IPsec is only supported on OSPFv3

C. OSPF authentication is performed at the area level, and all devices in the same area must use same type of authentication and same password

D. IPsec transport mode is supported

E. IPsec tunnel mode is supported

You have been asked to implement 802.1X in your network and to ensure that all authorized users continue to be permitted should the RADIUS server fail. Which solution will satisfy this requirement?

A. Implement the persistent MAC feature with the override option.

B. Implement the server fail fallback feature with the override option.

C. Implement the persistent MAC feature with the use-cache option.

D. Implement the server fail fallback feature with the use-cache option.
