Practice questions
Q1Which pairing of network category and typical coverage area is most accurate?
LAN is the best match for a local area such as a computer lab, office floor, building, or campus. PAN is smaller, MAN is city-scale, and WAN spans large geographical regions.
Q2A host is sending data over the Internet using the TCP/IP protocol suite. Which order correctly shows the data moving downward through the main TCP/IP layers before transmission?
In the Internet architecture, user data starts at the Application layer, is passed to a Transport protocol such as TCP or UDP, then to the Internet layer for IP delivery, and finally to the Link layer for the directly connected network.
Q3At which OSI layer is an Ethernet frame primarily associated?
Ethernet uses frames that carry link-layer addressing and control information for local network delivery. In the OSI model, this makes the frame a Data Link layer unit rather than a transport or application unit.
Q4A host wants to send a packet to a destination outside its own local network. Which configured address is normally used as the next hop?
The subnet mask tells a host whether the destination is local. If it is not local and no more specific route exists, the host forwards the packet to its default gateway, which is usually a router interface on the same LAN.
Q5A user enters www.example.com in a browser. Which service is primarily used to translate that domain name into an IP address?
The Domain Name System provides name resolution. Before a browser can contact the target server, the domain name must be resolved to an IP address that can be used by the Internet layer for routing.
