Juniper Enterprise Routing and Switching Support, Professional (JNCSP-ENT) : JN0-694

Referring to the exhibit, an administrator notices that the VLAN interface is not coming up. What would cause this problem? Click the Exhibit to see a larger version.

• A. All member interfaces are in access mode
• B. All member interfaces are down.
• C. The subnet mask is incorrect.
• D. The unit number for the VLAN is misconfigured.

There is a lot of traffic marked with IP precedence values af2l and af3l that ingresses the router. The af3l traffic should be using the expedited forwarding queue, but the traffic is much lower than expected and there are no drops seen on the egress interface. Referring to the exhibit, what is causing the problem?

• A. The MF classifier is forwarding most of the af3l traffic to the best-effort queue.
• B. The assured forwarding queue has a strict high priority and is starving the expedited forwarding queue.
• C. The expedited forwarding queue has a low priority value; therefore the traffic is not serviced.
• D. The MF classifier is does not match on af3l and therefore the traffic is being dropped.

The exhibit shows the BGP configuration for a router. The router should be receiving an identical set of prefixes over its two peering sessions. You want to ensure the router is using both routes for forwarding. Which command will show this information?

• A. show bgp neighbor
• B. show route protocol bgp
• C. show route receive-protocol bgp <neighbor address>
• D. show route forwarding-table

You are asked to troubleshoot an access control issue on your EX Series switch. The user connecting through port ge-0/0/1 indicates that their 802.1X supplicant is failing authentication and they are not able to connect to the network.
Referring to the exhibit, what is causing the 802.1X supplicant to fail?

• A. The supplicant timeout value is set too low.
• B. The supplicant mode is defined as multiple.
• C. The MAC restrict option is configured.
• D. The reauthentication interval is set too high.

The exhibit shows a small switched network, some details about the MSTP configuration in the network, and the VLANs that are trunked over each link. When Switch2 reboots, users in VLAN 400 on Switch3 report that they lose connectivity to resources in VLAN 400 on Switch4.
What is the cause of this problem?

• A. There are mismatched bridge priorities.
• B. VLAN 400 is trunked between Switch3 and Switch4.
• C. There is a mismatched MSTP configuration name.
• D. VLAN 400 is not trunked between Switch1 and Switch3.
