A network administrator sets up 802.1X authentication to a RADIUS server on an AOS-Switch. The RADIUS server and user devices are both set up to use PEAP MSCHAPv2. The administrator tests the authentication and sees the output shown in the exhibit. Which issue could cause this output?

• A.The administrator entered the wrong password for the test account
• B.The switch does not have a certificate for port-access installed on the switch
• C.The switch port is set for user mode 802.1X, but the RADIUS server is set for port mode
• D.The RADIUS shared secret does not match on the switch and the server

OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is configured with this range for Area 1: 10.10.0.0/17.
Which type of issue occurs due to this mismatch?

• A.The ABRs create a discontiguous area and disrupt intra-area routing between devices within Area 1.
• B.The ABRs advertise routes inconsistently, and they could potentially introduce a routing loop.
• C.The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.
• D.The ABRs lose adjacency entirely and cannot route traffic between each other at all.

Switch-1 and Switch-2 connect on interface A23. The switches experience a connectivity issue. The network administrator sees that both switches show this interface as up. The administrator sees the output shown in the exhibit on Switch-1.
What is a typical issue that could cause this output?

• A.a hardware issue, such as a broken cable
• B.asymmetric routing introduced by a routing configuration error
• C.mismatched IP addresses on the VLAN for the link
• D.an issue with queuing, caused by mismatched QoS settings
