 An autonomous system number (ASN) is used to identify a group of routers that are under a single administrative domain.

Answer: C
 The gateway of last resort is a default gateway that is used by a router when it doesn't have another route for a particular destination.

Answer: E
 An interior router is a router that resides within an autonomous system and is used to route traffic within the network.

Answer: J
 A routing metric is a value that is used by a router to determine the best path to a particular destination.

Note: Administrative distance, latency, MTU, neighbor discovery, and probe are also important terms in networking, but they don't specifically match the given statements.

Question 4

A)administrative distance
B)autonomous system number
C)gateway of last resort
D)gateway router
E)interior router
F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

The statement describes a probe, which is sent by tracert and traceroute utilities to gather information about the route.

Note: The other terms listed are not related to the specific purpose described in the statement.

Question 5

Matching
Match each correct item with the statement below.
-The delay between the transmission of a signal andits receipt.
A)administrative distance
B)autonomous system number
C)gateway of last resort
D)gateway router
E)interior router
F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

Latency is the delay between the transmission of a signal and its receipt.

Answer: G
 MTU (maximum transmission unit) is the largest size packet or frame that can be transmitted without fragmentation on a network.

Answer: J
 Routing metric is a value used by routers to determine the optimal path for sending packets. It can take into account factors such as bandwidth, delay, hops, and cost.

Note: The other terms (A, B, C, D, E, H, I) are also important for networking but don't directly relate to the given statement.

Question 6

Matching
Match each correct item with the statement below.
-A router that directs data between networkswithin the same autonomous system.
A)administrative distance
B)autonomous system number
C)gateway of last resort
D)gateway router
E)interior router
F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

An interior router is specifically designed to route data within an autonomous system, making it the correct match for the statement.

Question 7

Matching
Match each correct item with the statement below.
-Properties of a route used by routing protocolsto determine the best path to a destination when variouspaths are available.Routing metrics may be calculated usingany of several variables,including hop count,bandwidth,delay,MTU,cost,and reliability.
A)administrative distance
B)autonomous system number
C)gateway of last resort
D)gateway router
E)interior router
F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

Routing metric is used to determine the best path to a destination based on various properties or variables such as hop count, bandwidth, delay, MTU, cost, and reliability.

Answer: G
 MTU (maximum transmission unit) is one of the variables used to calculate routing metrics. It specifies the largest size of data packet that can be transmitted over a network path without fragmentation.

Answer: A
 Administrative distance is not related to routing metrics, but it is a property used by a routing protocol to select the best path when multiple routes are available. It is a measure of the reliability or trustworthiness of the source of the routing information.

Question 8

Matching
Match each correct item with the statement below.
-The router on a network that acceptsall unroutable messages from other routers.

F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

The "gateway of last resort" is the router on a network that accepts all unroutable messages from other routers. It is essentially the default route for packets that have destinations not found in the routing table.

Question 9

Matching
Match each correct item with the statement below.
-A process whereby routers learn aboutall of the devices on their networks.On IPv4 networks,this process is managed by ARP with help from ICMP.On IPv6 networks,NDP (Neighbor Discovery Protocol)automatically detects neighboring devices and automaticallyadjusts when nodes fail or are removed from thenetwork.
A)administrative distance

Accepted Answer

The statement is describing the process of neighbor discovery and how it is used on IPv6 networks to automatically detect and adjust to neighboring devices. None of the other choices match this description.

Question 10

Matching
Match each correct item with the statement below.
-A number indicating a protocol'sreliability,with lower values being given higher priority.This assignment can be changed by a network administratorwhen one protocol should take precedence over a previouslyhigher-rated protocol on a network.
A)administrative distance
B)autonomous system number
C)gateway of last resort
D)gateway router
E)interior router
F)latency
G)MTU (maximum transmission unit)
H)neighbor discovery
I)probe
J)routing metric

Accepted Answer

Administrative distance is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. The lower the administrative distance value, the more trustworthy the source and hence, the higher the priority of the route. Network administrators can adjust these values to influence route selection according to their network policies or requirements.
