Question 1 of 15
1. Question
2 pointsWhat are two functions that are provided by the network layer? (Choose two.)Correct
Incorrect
The network layer is primarily concerned with passing data from a source to a destination on another network. IP addresses supply unique identifiers for the source and destination. The network layer provides connectionless, best-effort delivery. Devices rely on higher layers to supply services to processes.

Question 2 of 15
2. Question
1 pointsHow does the network layer use the MTU value?Correct
Incorrect
The data link layer indicates to the network layer the MTU for the medium that is being used. The network layer uses that information to determine how large the packet can be when it is forwarded. When packets are received on one medium and forwarded on a medium with a smaller MTU, the network layer device can fragment the packet to accommodate the smaller size.

1 pointsIf there are two or more possible routes to the same destination, the …………… is used to determine which route is used in the routing table.
Correct
Incorrect
If there are two or more possible routes to the same destination, the metric is used to decide which route appears in the routing table.

4. Question
1 pointsRefer to the exhibit. Fill in the blank.
A packet leaving PC-1 has to traverse ………… hops to reach PC-4.
Correct
Incorrect
A hop is an intermediary Layer 3 device that a packet has to traverse to reach its destination. In this case, the number of hops a packet has to traverse from PC-1 to PC-4 is three, as there are three routers from source to destination.

5. Question
1 pointsHere is a link to the PT Activity.
Open the PT activity. Perform the tasks in the activity instructions and then answer the question.
Which interfaces in each router are active and operational?Correct
Incorrect
The command to use for this activity is show ip interface brief in each router. The active and operational interfaces are represented by the value “up” in the “Status” and “Protocol” columns. The interfaces in R1 with these characteristics are G0/0 and S0/0/0. In R2 they are G0/1 and S0/0/0.

Question 6 of 15
6. Question
1 pointsWithin a production network, what is the purpose of configuring a switch with a default gateway address?Correct
Incorrect
A default gateway address allows a switch to forward packets that originate on the switch to remote networks. A default gateway address on a switch does not provide Layer 3 routing for PCs that are connected on that switch. A switch can still be accessible from Telnet as long as the source of the Telnet connection is on the local network.

Question 8 of 15
8. Question
1 pointsFill in the blank.
The acronym ……………….. is used to define the process that allows multiple devices to share a single routable IP address.Correct
Incorrect
NAT or Network Address Translation is the process of modifying the IP packet header information on packets going outside the corporate network. Corporate networks typically use private addresses on the inside LAN and need a public address to be able to communicate through the WAN.

9. Question
1 pointsWhich IPv4 address can a host use to ping the loopback interface?Correct
Incorrect
A host can ping the loopback interface by sending a packet to a special IPv4 address within the network 127.0.0.0/8.

Question 10 of 15
10. Question
1 pointsWhich value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?Correct
Incorrect
When a router receives a packet, the router will decrement the Time-to-Live (TTL) field by one. When the field reaches zero, the receiving router will discard the packet and will send an ICMP Time Exceeded message to the sender.

Question 12 of 15
12. Question
1 pointsDuring the boot process, where will the router bootstrap program look for the IOS image by default?Correct
Incorrect
The IOS image is typically stored in flash memory. If the image is not in flash memory when the router boots, the router bootstrap program can look for it on a TFTP server.

Question 13 of 15
13. Question
1 pointsWhen transporting data from real-time applications, such as streaming audio and video, which field in the IPv6 header can be used to inform the routers and switches to maintain the same path for the packets in the same conversation?Correct
Incorrect
The Flow Label in IPv6 header is a 20-bit field that provides a special service for real-time applications. This field can be used to inform routers and switches to maintain the same path for the packet flow so that packets will not be reordered.
