Computer Networking Chapter 5 Quiz

What is the role of the Gateway/next hop parameter in a routing table?

It determines the speed at which the packet is forwarded.

It specifies the final destination of the packet.

It identifies the router's physical location.

It indicates the next router or gateway along the path to the destination.

It indicates the next router or gateway along the path to the destination

10.0.1.0/24

0.0.0.0/0

10.0.3.0/24

What is the default probe message type used by the tracert command on Windows systems?

TCP SYN

UDP

ARP Request

ICMP Echo Request

How does IPv6 handle packet fragmentation differently from IPv4?

IPv6 uses a different header field for fragmentation management.

IPv6 increases the MTU to avoid fragmentation.

IPv6 allows routers to perform fragmentation.

IPv6 requires the host to perform path MTU discovery.

IPv6 requires the host to perform path MTU discovery.

What is the purpose of inspecting the ARP cache table?

To increase the router's memory

To view the device's routing table

To modify the device's IP address

To discover duplicate IP addresses and misconfigurations

To discover duplicate IP addresses and misconfigurations

What is the purpose of applying an IP configuration to each interface on a router?

To enhance the processing power of the router

To increase the storage capacity of the router

To enable the router to serve its function in routing data

To secure the router from external threats

To enable the router to serve its function in routing data

Which of the following best describes a directly connected route in a routing table?

A route that is manually added and requires manual updates

A route for subnets and IP networks that are not directly attached to the router

A route that is automatically added for each active router interface, representing subnets for which the router has a local interface

A special type of static route that serves as the gateway of last resort

A route that is automatically added for each active router interface, representing subnets for which the router has a local interface

A network technician is using traceroute on a corporate network to make use of ICMP "Time Exceeded" in order to identify routers along a delivery path.

What is the TCP/IP feature that traceroute uses to accomplish this.?

Static route

Time To Live (TTL) header field

Default route

Fragmentation

Time To Live (TTL) header field

Which command outputs the active routing table and includes details such as destination, gateway, and the source of the route?

show arp

show route

ip route show

route print

show route

What does the Time to Live (TTL) header field represent in a packet?

The maximum distance the packet can travel

The maximum time the packet can exist on the network

The maximum number of routers the packet can pass through

The priority assigned to the packet for data transmission

The maximum number of routers the packet can pass through

If a router has two routes to the same destination with identical prefix lengths from the same routing protocol, how does it choose which route to use?

By using the Administrative Distance (AD) value

By preferring the route with the shortest prefix

By choosing the route with the lowest metric

By selecting the route with the largest packet size

By choosing the route with the lowest metric

What happens when a routing protocol's database contains more than one route to the same destination prefix?

The router randomly selects one of the routes for use.

The router selects the route with the highest cost metric.

The path with the lowest cost metric is used.

All routes are used simultaneously to balance the load.

The path with the lowest cost metric is used

What can cause convergence problems in a dynamic routing network?

Consistent routing information across all routers

A stable network with no changes

The use of static routing protocols

A flapping interface

A flapping interface

What is the purpose of the hello messaging in EIGRP?

To transmit routing updates

To encrypt data packets

To confirm connectivity with its neighbors

To assign IP addresses to routers

To confirm connectivity with its neighbors

What is the principal difference between link state and distance vector protocols?

Link state protocols rely on directly connected neighbors for information about remote networks.

Distance vector protocols allow each node to hold a copy of the complete network topology.

Distance vector protocols use a shortest path first algorithm.

Link state protocols allow each node to hold a copy of the complete network topology.

Link state protocols allow each node to hold a copy of the complete network topology

What type of routing system is OSPF considered to be?

Circular

Hierarchical

Flat

Linear

Hierarchical

What protocol does BGP use for its operation?

ARP

UDP

TCP

ICMP

TCP

In RIP, what happens when a router receives an update that includes a route to a network it already knows about?

It increments the hop count of its existing route by 1.

It replaces its existing route with the new one only if the hop count is lower.

It ignores the update.

It always replaces its existing route with the new one.

It replaces its existing route with the new one only if the hop count is lower

What was the primary reason for the development of Enhanced IGRP (EIGRP)?

To replace the TCP/IP protocol

To address limitations in IGRP, such as lack of support for classless addressing

To provide a routing protocol for inter-domain routing

To improve the security features of routing protocols

To address limitations in IGRP, such as lack of support for classless addressing

Under which of the following circumstances might you implement BGP on your company network and share routes with internet routers?

If the network has over 15 hops

If the network is connected to the Internet using multiple ISPs

If the network has over 15 areas and uses IPv6

If the network is connected to the Internet using public addressing

If the network is connected to the Internet using multiple ISPs
