Chapter - 9 Module Quiz - Address Resolution

Which destination address is used in an ARP request frame? - 255.255.255.255 - 01-00-5E-00-AA-23 - 127.0.0.1 - FFFF.FFFF.FFFF - 0.0.0.0

- FFFF.FFFF.FFFF

Which two ICMPv6 messages are used during the Ethernet MAC address resolution process? (Choose two.) - router advertisement - router solicitation - neighbor solicitation - echo request - neighbor advertisement

- neighbor solicitation - neighbor advertisement

Which IPv4 address can a host use to ping the loopback interface?

172.0.0.1

What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?

It forwards the frame out of all ports except for the port at which the frame was received.

Which field in an IPv4 packet header will typically stay the same during its transmission?

Destination Address

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 type of information is contained in an ARP table?

IPv4 address to MAC address mappings

What addresses are mapped by ARP?

IPv4 address to a destination MAC address.

Which statement accurately describes a characteristic of IPv4?

IPv4 has a 32-bit address space.

The ARP table in a switch maps which two types of address together?

Layer 3 address to a Layer 2 address.

Which router component holds the routing table, ARP cache, and running configuration file?

RAM

Which characteristic describes an IPv6 enhancement over IPv4?​

The IPv6 header is simpler than the IPv4 header is, which improves packet handling.

How does the network layer use the MTU value?

The MTU is passes to the network layer by the data link layer

A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?

The packet will be sent directly to the destination

A PC is configured to obtain an IPv4 address automatically from network 192.168.1.0/24. The network administrator issues the arp -a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry? - This entry maps to the default gateway, - This is a static map entry. - This is a dynamic map entry. - This entry refers tp the PC itself.

This is a static map entry

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on sending host.

A cybersecurity analyst believes an attacker is spoofing the MAC address of the default gateway to perform a man-in-the-middle attack. Which command should the analyst use to view the MAC address a host is using to reach the default gateway?

arp -a

Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?

it sends the frame to all ports except the port on which it received the frame.

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

create a new layer 2 Ethernet frame to be sent to the destination

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?

destination IP address

Which information is used by routers to forward a data packet toward its destination?

destination IP address

Which command can be used on a Windows host to display the routing table?

netstat -r

What is one function of the ARP protocol?

resolving an IPv4 address to a MAC address.

What information is added during encapsulation at OSI Layer 3?

source and destination IP address

When an IPv4 packet is sent to a host on a remote network, what information is provided by ARP?

the MAC address of the router interface closest to the sending host.

How does the ARP process use an IPv4 address?

to determine the MAC address of a device on the same network.

What is the purpose of ARP in an IPv4 network?

to obtain a specific MAC address when an IP address is known.

What was the reason for the creation and implementation of IPv6?

to relieve IPv4 address depletion
