NIIT Lab@Home 5 ICTWC
1. New laptop computers are being introduced for some of the managers in A. Datum Corporation. You need to test how the IPv4 configuration will behave when the managers are away from the office and a DHCP server is unavailable. Objectives Modify the IPv4 settings for a LAN connection. Configure a LAN connection to use DHCP.
For this lab, you will use the available virtual machine environment. Before you begin the lab, you must
complete the following steps:
1. On the host computer, click Start, point to Administrative Tools, and then click Hyper-V Manager.
2. In Hyper-V® Manager, click 20687A-LON-DC1, and in the Actions pane, click Start.
3. In the Actions pane, click Connect. Wait until the virtual machine starts.
4. Log on using the following credentials:
o User name: Adatum\Administrator
o Password: Pa$$w0rd
5. Repeat steps 2-4 for 20687A-LON-CL1.
Enabling Automatic IPv4 Configuration
The main tasks for this exercise are as follows:
1. Verify the current IPv4 configuration.
2. Configure the computer to obtain an IPv4 address automatically.
3. Verify the new IPv4 configuration.
Task 1: Verify the current IPv4 configuration
1. Log on to LON-CL1 virtual machine as Adatum\Administrator with the password Pa$$w0rd.
2. Open a command prompt, and then run the command IPConfig /all.
o What is the current IPv4 address?
o What is the subnet mask?
o To which IPv4 network does this host belong?
o Is DHCP enabled?
Task 2: Configure the computer to obtain an IPv4 address automatically
1. Use Network and Sharing Center to view the properties of Local Area Connection.
2. Modify TCP/IPv4 to:
o Obtain an IP address automatically.
o Obtain a DNS server address automatically.
Task 3: Verify the new IPv4 configuration
• In the Local Area Connection Status window, view the Details.
o What is the current IPv4 address?
o What is the subnet mask?
o To which IPv4 network does this host belong?
o Is DHCP enabled?
o When does the DHCP lease expire?
Results: After this exercise, you will have configured LON-CL1 to obtain an IPv4 configuration
automatically from a DHCP server.
Configuring IPv4 Manually

Additionally, they would like to enable visitors to connect their laptops to a restricted network that provides Internet access only. Objectives Create an implementation plan for a wireless network. Troubleshoot issues arising from the wireless deployment plan. Configure a wireless network policy.
Task 1: implementation plan for a wireless network.
Holly Dickson is the IT manager at A. Datum, and you have been working with her on the wireless
networking project. Holly wants you to determine what you need to enable wireless access for employees
and visitors. The A. Datum offices take up the entirety of a small building that spans two floors, with the
employees mainly confined to the upper floor. The ground floor provides conferencing facilities and a
reception area. Holly has produced the A. Datum Wireless Network Requirements document. You must
consider each requirement, and then make a corresponding proposal that indicates how you will meet
that requirement.
Requirements Overview
I want to deploy wireless networks throughout the London offices.
Security is critical, and we must deploy the strongest security measures available.
Some of our older computer equipment supports earlier wireless standards only.
Cordless telephones are in use in some parts of the building.
We are located in a busy trading district, with other commercial organizations located nearby. Again, it
is important that our network is not compromised.
