Part 2.1

Which scenario best demonstrates an advantage of static routing over dynamic routing?

• A small network with infrequent topology changes where simplicity is preferred

• A large enterprise network with frequent link failures

• An ISP backbone with multiple redundant paths

• A network requiring automatic route updates

Given a network that does not change often, why might an administrator choose static routing?

• To reduce the need for manual configuration

• To minimize routing protocol overhead and increase predictability

• To automatically adapt to network failures

• To support load balancing across multiple links

How does a dynamic routing protocol like OSPF respond to a failed link compared to static routing?

• It requires manual reconfiguration

• It automatically recalculates routes and updates the routing table

• It ignores the failure and continues using the old route

• It disables all routing

Which of the following best describes the main function of Border Gateway Protocol (BGP)?

• It is used for routing within a single organization

• It is used for exchanging routing information between different autonomous systems

• It is used for translating private IP addresses to public IP addresses

• It is used for encrypting network traffic

Which dynamic routing protocol is most suitable for large enterprise networks that require hierarchical design?

• RIP

• OSPF

• EIGRP

• BGP

If two routes to the same destination exist, one with an administrative distance of 90 and another with 120, which will be selected by the router?

• The route with administrative distance 120

• The route with administrative distance 90

• Both routes will be used equally

• The route with the longest prefix length

A router receives two routes to the same destination: one with a prefix length of /24 and another with /16. Which route will it choose?

• The /16 route

• The /24 route

• Both routes

• The route with the lowest metric

How does a routing protocol use metrics to select the best path?

• It chooses the path with the highest metric value

• It chooses the path with the lowest metric value

• It ignores metrics and uses administrative distance only

• It always selects the static route

How does Port Address Translation (PAT) differ from traditional NAT?

• PAT assigns a unique public IP to each private device

• PAT uses a single public IP address with different port numbers for multiple private devices

• PAT encrypts all outgoing traffic

• PAT is only used for IPv6 networks

Which scenario best illustrates the use of NAT in a home network?

• Each device has its own public IP address

• All devices share one public IP address but have unique private IP addresses

• Devices communicate only within the local network

• Devices use static routing to reach the internet
