CompTIA Network+ N10-006 Q62

A desktop computer is connected to the network and receives an APIPA address but is unable to reach the VLAN gateway of 10.10.100.254. Other PCs in the VLAN subnet are able to reach the Internet. Which of the following is MOST likely the source of the problem?

A. 802.1q is not configured on the switch port
B. APIPA has been misconfigured on the VLAN
C. Bad SFP in the PC’s 10/100 NIC
D. OS updates have not been installed

Correct Answer: A
Section: Network operations

Explanation:
APIPA addresses are self-configured and are used when the client is unable to get proper IP configuration from a DHCP server. One possible source of this problem is that switch port, to which the computer is connected, is misconfigured. The 802.1q protocol is used to configure VLAN trunking on switch ports.
