9.4.2 Module Quiz – Address Resolution
1. Which destination address is used in an ARP request frame?
2. What addresses are mapped by ARP?
- destination MAC address to a destination IPv4 address
- destination IPv4 address to the source MAC address
- destination IPv4 address to the destination host name
- destination MAC address to the source IPv4 address
3. What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?
- It initiates an ARP request.
- It broadcasts the frame out of all ports on the switch.
- It notifies the sending host that the frame cannot be delivered.
- It forwards the frame out of all ports except for the port at which the frame was received.
4. Which two ICMPv6 messages are used during the Ethernet MAC address resolution process? (Choose two.)
- router solicitation
- router advertisement
- neighbor solicitation
- neighbor advertisement
- echo request
5. Which router component holds the routing table, ARP cache, and running configuration file?
6. What type of information is contained in an ARP table?
- switch ports associated with destination MAC addresses
- domain name to IP address mappings
- routes to reach destination networks
- IP address to MAC address mappings
7. A PC is configured to obtain an IP 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 is a static map entry.
- This is a dynamic map entry.
- This entry refers to the PC itself.
- This entry maps to the default gateway.
8. 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?
- ipconfig /all
- route print
- netstat -r
- arp -a
9. What is a function of ARP?
- resolving MAC addresses to IPv4 addresses
- resolving port addresses to MAC addresses
- resolving MAC addresses to port addresses
- resolving IPv4 addresses to MAC addresses
10. What is the purpose of ARP in an IPv4 network?
- to forward data onward based on the destination IP address
- to obtain a specific MAC address when an IP address is known
- to forward data onward based on the destination MAC address.
- to build the MAC address table in a switch from the information that is gathered.
11. Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?
- It drops the frame.
- It sends the frame to all ports except the port on which it received the frame.
- It sends the frame to all ports that are registered to forward broadcasts.
- It sends the frame to all ports.
12. When an IP packet is sent to a host on a remote network, what information is provided by ARP?
- the IP address of the destination host
- the IP address of the default gateway
- the MAC address of the router interface closest to the sending host
- the MAC address of the switch port that connects to the sending host
13. How does the ARP process use an IP address?
- to determine the MAC address of the remote destination host
- to determine the MAC address of a device on the same network
- to determine the amount of time a packet takes when traveling from source to destination
- to determine the network number based on the number of bits in the IP address
14. The ARP table in a switch maps which two types of address together?
- Layer 3 address to a Layer 2 address
- Layer 3 address to a Layer 4 address
- Layer 4 address to a Layer 2 address
- Layer 2 address to a Layer 4 address
15. What is one function of the ARP protocol?
- obtaining an IPv4 address automatically
- mapping a domain name to its IP address
- resolving an IPv4 address to a MAC address
- maintaining a table of domain names with their resolved IP addresses
