One of the users whom you support uses a wireless laptop in the office and also takes it with her on business trips. She reports that when she uses the laptop in the lounge area of a hotel in which she frequently stays, she experiences delays and connection problems. She has no problems when using the laptop in her hotel room or when she returns to the office. What should you do to help solve the problem?

1. Advise the user to change the order in which her laptop attempts to access preferred networks.

2. Update the device driver for the user's wireless LAN adapter.

3. Change the SSID of your office network.

4. >>Disable network switching on one or both of the preferred networks that the user connects to in order to access the Internet from her hotel. <Correct>

Explanation:The likely cause of the reported behavior is that the lounge area of the hotel is within range of (and possibly equidistant between) two wireless networks and keeps switching between them. You can disable this feature or tell the user how to do so. You need to warn the user that if she moves to another part of the hotel, she might need to reconnect to a network.

Objective:Configuring Network Connectivity

Sub Objective(s):Configure network settings.

You are logged on to a client running Windows 7 named Canberra. You want to determine the media access control (MAC) address of a client running Windows 7 named Aberdeen, which is located on another subnet. Both computers are members of the same domain and your domain user account is a member of the local administrator group on both computers. The command WinRM Quickconfig has been executed on all clients running Windows 7 in your organization. Which of the following commands should you execute to accomplish your goal?

1. arp -a

2. nslookup Aberdeen

3. >>winrs -r:Aberdeen ipconfig /all <Correct>

4. winrs -r:Canberra ipconfig /all

Sam Abolrous hot-desks at the A. Datum Corporation. When he is working at a desk on the third floor, he wants all his print jobs to go to the printer LaserF3. When he is working at a desk on the second floor, he wants all his print jobs to go to the printer LaserF2. The third floor of the A. Datum building is covered by the wireless network Adatum3. The second floor of the A. Datum building is covered by the wireless network Adatum2. There is shielding between the floors, and the Adatum2 network cannot be accessed from the third floor. Similarly, the Adatum3 network cannot be accessed from the second floor. How do you configure location-aware printing on Sam's laptop running Windows 7 Enterprise?

You want Windows 7 to send you a message when the firewall blocks a new program when you are connected to your organization's domain network. Windows 7 should not send you a message when the firewall blocks a new program when you are connected to a public network. Which of the following settings should you configure? (Choose all that apply; each answer forms part of a complete solution.)

1. In the Home Or Work (Private) Network Location Settings area, select Turn On Windows Firewall and disable Notify Me When Windows Firewall Blocks A New Program.

2. In the Public Network Location Settings area, select Turn On Windows Firewall and enable Notify Me When Windows Firewall Blocks A New Program.

3. >>In the Home Or Work (Private) Network Location Settings area, select Turn On Windows Firewall and enable Notify Me When Windows Firewall Blocks A New Program. <Correct>

Don Hall has set up a wireless network at home. He is pleased with the ease with which he set up her third-party WAP by clicking a single button in the Web interface. However, his next door neighbor tells him that she can access his network from her home computer. What should Don do?

1. Implement ICS.

2. Change the channel his WAP uses.

3. Enable Windows Firewall.

4. >>Change the security settings of his WAP. <Correct>

Explanation:Don found the WAP setup easy because he accepted all the defaults and did not set up any security. He needs to change his SSID from its default value. He should also configure encryption and set up a passphrase. He should change the access password. He should consider restricting access by MAC address.

You are analyzing the configuration of an IPv6 network. Which of the following addresses can be used across the IPv6 Internet and is the equivalent of an IPv4 unicast public address?

1. fe80:d1ff:d166:7888:2fd6

2. 21cd:53::3ad:3f:af37:8d62 <Correct>

3. 1

4. >>fec0:0:0:0:fffe::1

You are configuring static IPv4 addresses for two computers, Perth and Brisbane, on an isolated private wired subnet. You configure Perth with the IPv4 address 172.16.10. 140 and the subnet mask 255.255.255.0. You configure Brisbane with the IPv4 address 172.16.10. 210 and the subnet mask 255.255.255.0. You enter ping 172.16.10.140 on Brisbane, but the command times out. Similarly, entering ping 172.16.0.210 on Perth fails to locate the Brisbane computer's IPv4 address. What is the likely reason for this lack of connectivity?

1. The computers should have different subnet masks.

2. You have not specified a default gateway.

3. >>You need to permit ICMPv4 traffic through the firewalls of both computers. <Correct>

4. DNS service is not available on the subnet

Explanation:By default Windows Firewall blocks the Ping command. You need to enable ICMPv4 traffic at both firewalls. At an elevated command prompt on both computers, enter netsh advfirewall firewall add rule name="ICMPv4" protocol=icmpv4:any,any dir=in action=allow.

Which of the following Windows PowerShell commands can you issue on a client running Windows 7 named Canberra to get a list of processes, including CPU and memory usage, on a client running Windows 7 named Aberdeen?

1. winrs -r:Canberra Get-Process

2. icm Canberra {Get-Process}

3. >>icm Aberdeen {Get-Process} <Correct>

4. winrs -r:Aberdeen Get-Process

Explanation:The Windows PowerShell command icm Aberdeen {Get-Process} opens a remote Windows PowerShell session to computer Aberdeen and runs the Get-Process cmdlet, which displays process information, including listing data about CPU and memory usage.




______________________________________________________________________________________________________________________________________________

You want to ensure that only certain designated wireless laptops can connect to your network. What do you need to enable?

1. WPA

2. >>MAC address control <Correct>

3. WEP

4. IPv4 address control

Explanation:The MAC address is unique to an interface and does not change. MAC ensures that only computers whose wireless interfaces have one of the listed MAC addresses can access a wireless network. Be aware that if a new computer needs to access the network, or if you replace the wireless adapter in a computer, you need to register the new MAC address in the WAP.
