A user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? (Choose two.)

In order for a user to access a website like http://www.cisco.com/, two critical configuration values must be properly set on the host device: the default gateway and the DNS server.

The default gateway is essential because it serves as the access point for sending packets from the host to other networks, specifically to the internet. If the default gateway is not configured correctly, the host will not be able to communicate with external networks, thus failing to reach any websites outside of its local network.

The DNS server is equally important as it translates human-readable domain names (like www.cisco.com) into IP addresses that computers use to identify each other on the network. Without proper DNS configuration, the host would not be able to resolve the domain name to the corresponding IP address, resulting in the inability to access the website.

While firewall settings can play a role in connectivity, they are not fundamental configuration values required for basic internet access. Network interface speed, although important for ensuring optimal data transmission, does not directly affect the ability to access external websites. Hence, the correct answers highlight the necessary configurations for successful web access.
