What configuration values must be set on a host for successful access to a URL such as http://www.cisco.com/?

• A. Firewall settings and static IP address
• B. DNS server and default gateway
• C. Proxy settings and compression settings
• D. Local IP address and subnet mask

Answer: (B)

For successful access to a URL like http://www.cisco.com/, it is essential for the host to have a DNS server and a default gateway configured. The DNS server is critical because it translates human-readable domain names, such as www.cisco.com, into IP addresses that computers use to identify each other on the network. Without a proper DNS configuration, the host would not be able to resolve the URL into an IP address, which is necessary for initiating any connections to web servers. The default gateway is also necessary because it acts as the access point or "gateway" for a host to communicate with devices outside its local network. If the host wants to access resources on the internet, it needs to direct its traffic to a gateway (often a router) that can route it to those external networks. The default gateway provides the route for traffic that is not destined for the local subnet, allowing the host to interact with the wider internet and reach the Cisco website. While firewall settings and a static IP address can be important in networking contexts, they are not fundamental for basic URL access. Likewise, proxy and compression settings, as well as local IP addresses and subnet masks, play roles in certain configurations but are not directly necessary for successfully accessing the website by resolving
