— Exhibit – — Exhibit — Click the Exhibit button. 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?

— Exhibit — — Exhibit — Click the Exhibit button. 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?

— Exhibit — — Exhibit — Click the Exhibit button. You have been asked to troubleshoot a
problem where a user is not able to send traffic through your switch. While troubleshooting,
you see the log messages shown in the exhibit. What is causing the problem?

— Exhibit — — Exhibit — Click the Exhibit button. Referring to the exhibit, an administrator
notices that all traffic is flooded out of all the ports in VLAN ws. What would cause this
problem?

— Exhibit — Click the Exhibit button. Traffic with the IPP value af21 should be assigned to
the expedited forwarding queue; however, this traffic is not being assigned to that queue.
Referring to the exhibit, what is causing this behavior?

— Exhibit — Click the Exhibit button. Traffic with the IP precedence value af21 ingresses the
router and should be rewritten with the same value as it egresses; however, this traffic is
rewritten to a different value. Referring to the exhibit, what is the source of this problem?

— Exhibit — — Exhibit — Click the Exhibit button. You are sending traffic to the ge-0/0/0
interface on R1 with the expedited forwarding (101) IP precedence bits. However, the
counters on the router show that it is not processing any traffic in the expedited forwarding
queue. Referring to the exhibit, what is causing the problem?

The exhibit shows part of the configuration for a router. You receive a complaint that the
router is not correctly reclassifying all traffic to the best-effort forwarding class when the
amount of IPv4 traffic exceeds 10 Mbps. You have isolated the problem to traffic with the IP
precedence bits set to the binary value 101. Which configuration is causing this behavior?

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?

You add a multicast source to a network. The source’s DR sends register messages to the
RP However, multicast clients are not able to receive traffic from the source. What are two
causes of this problem? (Choose two.)
