Troubleshooting Network Connectivity Issues

A network technician has just configured NAC for connections using Cat 6 cables.

However, none of the Windows clients can connect to the network.

Which of the following components should the technician check on the Windows workstations? (Choose two.)

A.

Start the Wired AutoConfig service in the Services console

B.

Enable IEEE 802.1q Authentication in Network Interface Card Properties

C.

Enable IEEE 802.1x Authentication in Network Interface Card Properties

D.

Start the Wireless AutoConfig service in the Services console

E.

Enable IEEE 802.3 Ethernet IPv6 in Network Interface Card Properties.

AC.

The scenario given is that a network technician has configured NAC (Network Access Control) for connections using Cat 6 cables, but none of the Windows clients can connect to the network. In this case, the technician should check two components on the Windows workstations to troubleshoot the issue.

A. Start the Wired AutoConfig service in the Services console: The Wired AutoConfig service is responsible for configuring network devices and connecting to wired networks. If this service is not started, the Windows clients will not be able to connect to the network. Therefore, the technician should check whether this service is running on the Windows workstations. If not, they should start it using the Services console.

C. Enable IEEE 802.1x Authentication in Network Interface Card Properties: IEEE 802.1x is an authentication standard for wired and wireless networks. It provides a framework for authenticating devices and users before allowing them to access the network. If the NAC configuration is set up to use IEEE 802.1x authentication, the Windows clients must also have this enabled in their network interface card properties. Therefore, the technician should check whether this option is enabled on the Windows workstations. If not, they should enable it in the Network Interface Card Properties.

B, D, and E are incorrect options.

B. Enable IEEE 802.1q Authentication in Network Interface Card Properties: IEEE 802.1q is a standard for VLAN tagging on Ethernet networks. It is not related to NAC configuration, and therefore, it is not relevant to the issue described in the scenario.

D. Start the Wireless AutoConfig service in the Services console: Wireless AutoConfig service is responsible for configuring wireless network devices and connecting to wireless networks. However, the scenario states that the network is using Cat 6 cables, which are wired connections, and therefore, this service is not relevant to the issue.

E. Enable IEEE 802.3 Ethernet IPv6 in Network Interface Card Properties: IEEE 802.3 is a standard for Ethernet networks, and IPv6 is a protocol for internet communication. However, this option is not relevant to the NAC configuration issue described in the scenario.
