Question 1
In the IPv4, which address is reserved and are not used as host ip address on IP networks?
Question 2
For which one of the following reasons does Internet Protocol (IP) use the time to-live (TTL) field in the IP datagram header?
Question 3
Network addresses is related to:
Question 4
Host A (on TCP/IP v4 network A) sends an IP datagram D to host B (also on TCP/IP v4 network B). Assume that no error occurred during the transmission of D. When D reaches B, which of the following IP header field(s) may be different from that of the original datagram D?
(i) TTL
(ii) Checksum
(iii) Fragment Offset
(i) TTL
(ii) Checksum
(iii) Fragment Offset
Question 5
In the IPv4 addressing format, the number of networks allowed under Class C addresses is
Question 6
Consider three IP networks A, B and C. Host HA in networks A sends messages each containing 180 bytes of application data to a host HC in network C. The TCP layer prefixes a 20 byte header to the message. This passes through an intermediate network B. the maximum packet size, including 20 byte IP header, in each network is:
A : 1000 bytes
B : 100 bytes
C : 1000 bytes
The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps = bits per second).
A : 1000 bytes
B : 100 bytes
C : 1000 bytes
The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps = bits per second).
Assuming that the packets are correctly delivered, how many bytes, including headers, are delivered to the IP layer at the destination for one application message, in the best case? Consider only data packets.
Question 7
In IPv4, Class A IP addresses, there are ______network address and ________host address.
Question 8
Suppose the round trip propagation delay for a 10 Mbps Ethernet having 48-bit jamming signal is 46.4 μs. The minimum frame size is___ bits.
Question 9
In an IPv4 datagram, the M bit is 0, the value of HLEN is 10, the value of total length is 400 and the fragment offset value is 300. The position of the datagram, the sequence numbers of the first and the last bytes of the payload, respectively are
Question 10
The subnet mask for a particular network is 255.255.31.0. Which of the following pairs of IP addresses could belong to this network?
