2. Checkpoint Exam

A network engineer subnets the network 192.168.100.0 /24 into 16 subnets. How many usable host addresses will be available on each of the subnets?

14

When a computer assembles a frame to be sent over the network, what is the maximum size of an Ethernet frame?

1518 bytes

What subnet mask would be associated with the IPv4 prefix of /28?

255.255.255.240

Refer to the exhibit. If all devices are using a subnet mask of 255.255.255.0, which laptop would have an IP address with the same network number as the server?

C

Which IPv4 header field is responsible for defining the priority of the packet?​

DS - differentiated services

Which field in an IPv6 packet is used by the router to determine if a packet has expired and should be dropped?

Hop Limit

What is correct in relation to NAT for IPv6?

It is a temporary mechanism to assist in the migration from IPv4 to IPv6.

Match the characteristics with the correct IP protocol version.

Refer to the exhibit. ServerB is attempting to contact HostA. Which two statements correctly identify the addressing that ServerB will generate in the process? (Choose two.)

ServerB will generate a frame with the destination MAC address of RouterB., ServerB will generate a packet with the destination IP address of HostA.

Refer to the exhibit. A computer that is configured with the IPv4 address as shown in the exhibit is unable to access the internet. What is the problem?​

The gateway address is in the wrong subnet.

Refer to the exhibit. The exhibit shows a small switched network and the contents of the MAC address table of the switch. PC1 has sent a frame addressed to PC3. What will the switch do with the frame?

The switch will forward the frame to all ports except port 4.

What are two functions that are provided by the network layer? (Choose two.)

directing data packets to destination hosts on other networks, providing end devices with a unique network identifier

What is one advantage that the IPv6 simplified header offers over IPv4?

efficient packet handling

Which field in the IPv6 header points to optional network layer information that is carried in the IPv6 packet?

next header

Refer to the exhibit. The switches have a default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for the default gateway. Which network devices will receive the ARP request sent by host A?

only hosts B, C, and router R1

Which information does a switch use to populate the MAC address table?

the source MAC address and the incoming port

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

to identify the network address of the destination network
