Network Routing, Firewalls, and NAT

What is the primary function of a routing table?

• Store IP addresses of all connected devices

• Determine the best path for forwarding packets

• Manage user authentication for network access

• Assign IP addresses to devices on the network

Which of the following information is NOT typically found in a routing table entry?

• Destination network

• Next hop address

• Packet size

• Metric value

What is a directly connected route?

• A route manually added by an administrator

• A route to a network that is physically attached to the router

• A route learned through a dynamic routing protocol

• A backup route used in case of failure

What is the function of the tracert or traceroute command?

• Display current IP configuration settings

• Test connectivity and measure round-trip time

• Show the path a packet takes to its destination

• Block unauthorized network traffic

What is a key disadvantage of static routing?

• It requires constant manual updates

• It cannot be used with IPv6 networks

• It automatically updates in case of network changes

• It uses excessive bandwidth

Which factor is NOT typically used to determine route selection in dynamic routing?

• Hop count

• Bandwidth

• Number of connected users

• Delay

Which of the following is a dynamic routing protocol?

• RIP

• OSPF

• BGP

• All of the above

Which dynamic routing protocol is best suited for large-scale enterprise networks?

• RIP

• OSPF

• Static Routing

• NAT

Why is NAT used in IPv4 networks?

• To encrypt network traffic

• To provide a high-speed internet connection

• To allow multiple devices to share a single public IP address

• To improve network security

What is the key difference between static NAT and dynamic NAT?

• Static NAT maps multiple private IPs to one public IP, while dynamic NAT maps one-to-one dynamically

• Static NAT changes IP addresses frequently, while dynamic NAT keeps them constant

• Static NAT is only used for wireless networks, while dynamic NAT is for wired networks

• Static NAT is less secure than dynamic NAT
