IP Connectivity

Question Image

Refer to the exhibit. A newly configured PC cannot connect to the internet using TCP port 80 to www.cisco.com. Which setting must be changed for the connection to function?

  • A Subnet Mask
  • B DNS Servers
  • C Default Gateway
  • D DHCP Servers
Explanation

Accessing www.cisco.com by name requires DNS resolution before the PC can open an HTTP connection on TCP port 80. The local IP address, subnet mask, and default gateway shown still place the host and gateway on the same local network, so Layer 3 reachability to the gateway is not the blocking issue here. The setting that must be corrected is the DNS server configuration.
