Based on the specific protocol, the maximum transmission units (MTUs), can range from 296 to 65.535.
What would the advantages be of having a large MTU
What are the advantages of having an MTU that is small?
Compare and contrast CSMA/CD to CSMA/CA.
What’s the purpose of including the IP head and the first 8 bytes in datagram data in error reporting ICMP message?
Which ICMP messages are part of the IP Datagram?
Why is this necessary?
ISP has allocated the following classless addresses to an organization.
220.127.116.11/28 Create a list of addresses within this range. Identify those that can use hosts (total number and IP address), subnet mask, and direct broadcast address.
Show as much detail as you can about your calculations
A router running RIP will have a routing list with 20 entries.
a) What number of periodic times is required to deal with this table?
Simply answer the question.
b. How many expiration periods are required to manage this table.
c. How many garbage collection time are required to deal with this table if five routers have failed?
Give your answer.
You want to optimize the use of your network addresses as a network administrator for an expanding Internet service provider (ISP).
A classless network of 18.104.22.168/23 was assigned to you by Internet Assigned Numbers Authority.
You’ve decided to use network addresses to meet the requirements of 16 corporate clients who require IP addresses ranging from 18 to 30 hosts each.
You can calculate the subnet mask for each customer without using a Subnet Calculator.
List all subnetwork addresses and the subnetmask that will be created.
Show the calculation in detail.
You are a help desk employee and received a call saying that an employee can’t access the network resources.
You want to show the employee her IP address configuration.
You sent an e-mail explaining to the employee what command-line tool to use and how it can be used to retrieve the information she needs.
Following your instructions, the employee informs you that her IP is 169.254.14.11 and has the subnet mask of 255.255.0.0.
What conclusion are you able to draw from this information
As the network administrator of a growing Internet service provider, you want to efficiently use your network addresses.
You have been assigned a Class C network number of 192.168.1.0 by the Internet Assigned Numbers Authority.
This Class C network contains addresses that you can use to fulfill the IP address requirements for 16 corporate customers, who each require between 10 to 14 addresses.
You can calculate the subnet mask for them without using a Subnet Calculator.
List the subnet mask, and all subnetwork address that it will create.
Show details for each output
An organization receives a block address with the beginning address of 22.214.171.124/24.
Below are three subblocks that must be used by the organization to access its subnets.
O ne subblock for 120 addresses.
O ne Subblock of 60 Addresses.
?One block of 10 addresses
Answer the following questions, and then show detailed calculations for each.
Calculate total number IP addresses, first & last addresses for given block.
Calculate subnet mask and subnetwork address for each subnet.
There are many benefits to a larger MTU:
These devices are ideal for handling larger amounts of data over longer distances.
For fast delivery and very few lost datagrams, there is no significant fragmentation.
Small MTUs have the following advantages:
It is possible to transfer time sensitive data, such as audio and video, with good results.
The suit for multiplexing.
CSMA/CD is designed to enable collision detection.
The collision is detected by the terminations based upon working over system standards. The data is also detected depending on which transmitter does not waste time in continuation.
You can easily re-transmit the last information with this.
CSMA/CA doesn’t need to address the recovery of collisions.
The most important thing is to make sure that the medium is not in use.
You need to know how to find the busy spot where the transmitter will be operating before it begins transmitting.
Effectively minimizing the chance of collisions is possible by using the medium in a more efficient way.
This allows you to match the packets to their destination.
It is also important that you understand the error messages. This will allow you to focus on the messages that cannot be reached with the cause set under the original header.
It is essential to determine the router interface using the ICMP ping message.
The payload’s first bytes would contain information about the TCP source and destination ports.
For troubleshooting the problems, it is possible to access the source quench or TTL expiration messages.
IP header contains the IP information.
This information is necessary to guide the source/destination of the packet regarding packet information.
40 periodic times are required, two per period.
You will need 20 expiration dates, one for each period.
21 garbage collection times must be followed for each router.

These information indicate that subnet masking is incorrect, that DHCP errors have occurred and that automatic subnetting has not been performed.
It is possible that the client’s system has not been connected to the network. This will require it to be reset.
Available IP addresses within major network: 510
Number of IP addresses necessary: 224
Available IP addresses in subnets allocated: 224
About half of the major network address space available is being used
Around 100% of subnetted network addresses space is used
