46. Explain how Tracert uses an ICMP packet and the TTL value to map the path to an IP address.
ANSWER:
Tracert sends an ICMP to the IP address with a TTL value of 1. When the first router
receives the packet it decrements the TTL to 0, discards the packet, and sends a TTL-expired
packet to the sending computer. When the sending computer receives the TTL-expired
packet, it notes the address of the first router. Then it sends a second packet with a TTL of 2.
This time the packet gets to the second router, is discarded, and the second router sends a

TTL-expired packet. When Tracert receives this response, it notes the address of the second
router. This continues until the packet reaches the intended IP address.

47. How does TCP provide flow control and reliability?
ANSWER:
TCP sets a maximum number of bytes to transmit before it must receive an acknowledgment
of receipt from the receiving station. If it does not receive an acknowledgment within a
certain period, it assumes an error has occurred and begins to retransmit the data since the
last acknowledgment was received.

48. Briefly describe the three-way handshake that TCP uses to establish a connection.
ANSWER:
When a client computer makes a request, TCP begins the session by sending the receiving
computer, which is typically a server, a SYN segment. If the server is not busy, then it sends
back an ACK-SYN packet acknowledging the creation of the session. Then the client
computer sends back an ACK segment to finalize the connection.

49. What is the function of DNS, and at which layer does it operate?
ANSWER:
DNS allows computers to contact other computers using a familiar name instead of a hard-to–
remember IP address. DNS keeps records of which name corresponds to which IP address in
a DNS cache so that a frequently accessed address can be resolved quickly. DNS is an
Application layer protocol.
