- Question
Which statements are true regarding ICMP packets?
- They acknowledge receipt of a TCP segment.
- They guarantee datagram delivery.
- They can provide hosts with information about network problems.
- They are encapsulated within IP datagrams.
Options- A. 1 only
- B. 2 and 3
- C. 3 and 4
- D. 2, 3 and 4
- Correct Answer
- 3 and 4
ExplanationInternet Control Message Protocol (ICMP) is used to send error messages through the network, but they do not work alone. Every segment or ICMP payload must be encapsulated within an IP datagram (or packet). - 1. Which of the following is private IP address?

Correct Answer: 192.168.24.43
Explanation:
Class A private address range is 10.0.0.0 through 10.255.255.255. Class B private address range is 172.16.0.0 through 172.31.255.255, and Class C private address range is 192.168.0.0 through 192.168.255.255.
Correct Answer: 2, 3 and 5
Explanation:
SMTP, HTTP and FTP use TCP.
Correct Answer: Internet
Explanation:
The four layers of the DoD model are Application/Process, Host-to-Host, Internet, and Network Access. The Internet layer is equivalent to the Network layer of the OSI model.
Correct Answer: 1, 3 and 4
Explanation:
This seems like a hard question at first because it doesn't make sense. The listed answers are from the OSI model and the question asked about the TCP/IP protocol stack (DoD model). However, let's just look for what is wrong. First, the Session layer is not in the TCP/IP model; neither are the Data Link and Physical layers. This leaves us with the Transport layer (Host-to-Host in the DoD model), Internet layer (Network layer in the OSI), and Application layer (Application/Process in the DoD).
Correct Answer: PAT
Explanation:
Port Address Translation (PAT) allows a one-to-many approach to network address translation.
Correct Answer: 1, 3 and 6
Explanation:
DHCP, SNMP, and TFTP use UDP.
Correct Answer: TCP
Explanation:
Although Telnet does use TCP and IP (TCP/IP), the question specifically asks about layer 4, and IP works at layer 3. Telnet uses TCP at layer 4.
Correct Answer: Host-to-Host
Explanation:
The four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.
Correct Answer: 3, 4 and 5
Explanation:
Telnet, File Transfer Protocol (FTP), and Trivial FTP (TFTP) are all Application layer protocols. IP is a Network layer protocol. Transmission Control Protocol (TCP) is a Transport layer protocol.
Correct Answer: DHCP
Explanation:
Dynamic Host Configuration Protocol (DHCP) is used to provide IP information to hosts on your network. DHCP can provide a lot of information, but the most common is IP address, subnet mask, default gateway, and DNS information.
