Place a check mark beside each item below that is TRUE. Do not mark items that are false.
Jitter is a measure of the variation of delay.
The destination IP address in an IP packet may be not be changed by a router.
There are 2^16 class B addresses.
An ARP frame's PROTOCOL TYPE contains 0x0806 (in hexidecimal) to specify that high level protocol address is IPv4.
The padding field in an IP datagram, when used, is filled with zeros.
An ARP frame will have the value of 1 in the HARDWARE TYPE field when Ethernet is being used.
Routers store network addresses in their routing tables rather than host addresses.
IPv6 does not specify a broadcast destination address.
Ethernet frames are self-identifying while IP Packets are not.
QUESTION 2
Place a check mark beside the statements that are correct regarding an Ethernet MAC address.
The right-most 24 bits identify which host is on the Ethernet network and these bits must be unique on the Ethernet network segment.
A vendor can have more than one vendor code.
The left-most 24 bits in an Ethernet Mac address are the vendor's code number.
An Ethernet MAC address is 48 bits long.
QUESTION 3
What is the first assignable host address that could be used on the 10001000 subnet of 10.0.0.0 when borrowing 8 bits to subnet the address space?
10.128.1.0
00001010 10001000 10001000 00000001
10.136.0.254
00001010 10001000 00000000 00000001
10.0.128.1
00001010 00000000 10001000 00000001
QUESTION 4
An IP packet arrives at a router with destination IP address of 192.168.10.8. Which of the following outgoing route choices will the packet be sent on?
Send packets destined for network 192.168.0.0/16 out port 1.
Send packet destined for network 0.0.0.0/0 out port 2
Send packets destined for network 192.168.8.0/21 out port 3.
Send packets destined for network 192.168.10.0/28 out port 4.
QUESTION 2
Which one of the following is the most likely scenario for a 1400 Octet IPv4 Packet that needs to be sent across a link with an MTU of 1220 octets?
Divide the packet into three approximately equal sized fragments of 460 octets each (440 octets of data and 20 octets of header for each fragement).
Divide the packet into one 1220 octet fragment (1200 data octets and 20 octets of header) and one 200 octet fragment (180 octets of data and 20 octets of header).
Divide the packet into two equal sized fragments of 710 octets each (690 octets data and 20 octets of header each).
Discard the packet because it cannot be fragmented on an even boundary of 8 octets.

IP & ICMP:
When you send data from one device to another remote device, the IPv4 Datagram often travels through one or morerouters. There can be errors at routers while they try to forward the IPv4 Datagram to its final destination. The Internet Control Message Protocol (ICMP) protocol is used to report problems with delivery of IPv4 Datagrams within an IPv4network. ICMP is also used for other diagnosis and troubleshooting functions.
An Internet Control Message Protocol (ICMP) packet header is 8 Bytes long. The first four bytes always have the same meaning, and the contents of the remaining four depend on the ICMP packet type. An ICMP header follows the IP header in an IP datagram packet and Internet Control Message Protocol (ICMP) is considered to be an integral part ofIPv4.
