1. When configuring a switch, which command would you use to set the default gateway? A) ip default-gateway [ip address] B) ip route [ip address] C) switchport default-gateway [ip address] D) gateway [ip address] Answer: A) ip default-gateway [ip address] Rationale: The 'ip default-gateway' command is used to define the default gateway on a switch that is not using IP routing capabilities. 2. In intermediate routing, what is the purpose of a routing table? A) To list all active connections on a router B) To determine the best path for data packets C) To store MAC addresses D) To configure static routes Answer: B) To determine the best path for data packets Rationale: A routing table stores the routes to various network destinations and is used by routers to determine the best path for forwarding packets. 3. What is the benefit of using Variable Length Subnet Masking (VLSM)? A) It allows for more efficient use of IP addresses B) It simplifies the routing table C) It eliminates the need for routing protocols D) It provides better security Answer: A) It allows for more efficient use of IP addresses Rationale: VLSM allows for subnets of different sizes, making it possible to allocate IP addresses more efficiently according to the actual need, reducing waste. 4. What is the primary concern when scaling IP addresses within a network? A) Ensuring compatibility with IPv6 B) Maximizing the number of available addresses C) Minimizing the impact on network performance D) Preventing IP address conflicts Answer: B) Maximizing the number of available addresses Rationale: When scaling IP addresses, the main goal is to maximize
