Fragment-free forwarding method, also known as runtless switching, is a type of forwarding method used in networking. It is called runtless switching because it specifically focuses on preventing the forwarding of runt frames, which are frames that are too short to contain complete information. In fragment-free forwarding, the switch waits for a brief period of time to ensure that the first 64 bytes of a frame have been received before forwarding it. This helps to minimize the chances of forwarding incomplete or corrupted frames, improving network efficiency and reducing errors.

The correct answer is Bourne shell. The Bourne shell is the standard all-purpose shell that is commonly used in Unix-like operating systems. It was developed by Stephen Bourne and is known for its simplicity and efficiency. It provides a command-line interface for users to interact with the operating system and execute commands. The Bourne shell is often used as the default shell for many Unix-based systems and has influenced the development of other shells such as the Korn shell and C shell.

Border Gateway Protocol (BGP) is an example of an Exterior Gateway Protocol (EGP). BGP is used to exchange routing information between different autonomous systems (AS) on the internet. It is specifically designed to handle the routing between different networks and is widely used by internet service providers (ISPs) to establish connections and exchange routing information. BGP is a complex and robust protocol that allows for efficient and scalable routing on the internet. Open Shortest Path First (OSPF), Routing Information Protocol (RIP), and Enhanced Gateway Routing Protocol (EGRP) are examples of Interior Gateway Protocols (IGP), which are used within a single autonomous system.

Classless Inter-Domain Routing (CIDR) is the method that borrows bits from the host field of an IP address to create a subnet. CIDR allows for more flexible and efficient allocation of IP addresses by allowing variable length subnet masks (VLSM). This means that the subnet mask can be adjusted to accommodate different network sizes, rather than being limited to the fixed network sizes of classful subnet masking.
