Lab 5 Submission

Can anyone help?

This submission template is a convenient document for you to provide your

work and your answers for Lab 5. This submission template is intended to

be used in conjunction with the Lab 5 Instructions document. The

instructions document illustrates how to correctly derive the answers,

explains important theoretical and practical details, and contains the

complete set of instructions for this lab.

Section One – Variable Length Subnet Masks

2. Imagine that an organization is assigned the address block 169.222.0.0/18, and the

organization needs one subnet with 220 hosts, one subnet with 128 hosts, and one

subnet with 19 hosts.

Create the appropriate network identifiers for each subnet, using the process

established for VLSMs in the overview section. Refer to step 1 for a similar example.

Make sure to show your work.

3. Explain in your own words how the process of allocating subnets using VLSMs differs

from the process of allocating subnets using a fixed length subnet mask.

5. Imagine that an organization is assigned the address block 45.0.0.0/8, and the

organization has an existing subnet with 190 hosts, and another existing subnet with 53

hosts. Further imagine that after the network has been in used for some time, the

organization must add another subnet that requires 105 hosts.

First, use the process established in the overview section to create the network

identifiers for the two existing subnets. Second, use the same process to create the

network identifier for the new subnet (illustrated in step 4). Last, identify the number of

addresses that are left unallocated in the gap between the second and third subnet.

Make sure to show your work.

6. Explain in your own words why allocating a new subnet on an existing network results

in an unavoidable gap of unallocated addresses.

8. Now it is your turn to allocate a new subnet in-between existing subnets on a

network. In the three parts below, keep in mind that there will be a gap of unallocated

addresses in your subnet allocation, similar to the example given in step 7.

a) Imagine that an organization is assigned the address block 222.221.128.0/17, and the

organization has an existing subnet with 107 hosts, and another existing subnet with 51

hosts. Using the process given in the overview section, allocate both subnets and

identify the network identifier for both subnets. Make sure to show your work.

b) Now the organization decides to add an additional subnet that supports 113 hosts.

Allocate this subnet and identify its network identifier, making sure to show your work.

c) Last, the organization decides to add one additional subnet that supports 9 hosts.

Allocate this subnet and identify its network identifier, making sure to show your work.

9. Explain in your own words how the process of allocating a new subnet in-between

existing subnets works.

Metallic molybdenum can be produced from the mineral molybdenite, MoS2. The mineral is first oxidized in air to molybdenum trioxide and sulfur dioxide. Molybdenum trioxide is then reduced to metallic molybdenum using hydrogen gas. The balanced equations are given below.MoS2(s) + 7/2 O2(g) MoO3(s) + 2 SO2(g)MoO3(s) + 3 H2(g) Mo(s) + 3 H2O(s)Calculate the volumes of air and hydrogen gas at 27°C and 1.00 atm that are necessary to produce 1.00 103 kg of pure molybdenum from MoS2. Assume air contains 21% oxygen by volume and assume 100% yield for each reaction.
