Lesson 14

You are assisting a user with configuring a static IP address. The user has entered the following configuration values and now cannot access the Internet. Is there a configuration issue or a different problem?

• IP: 192.168.1.1

• Mask: 255.255.255.0

• Gateway: 192.168.1.0

• DNS: 192.168.1.0

• The IP address is incorrect

• 192.168.1.0 is not a host address

• Incorrect subnet mask

• There is no problem

You are assisting another user who is trying to configure a static IP on a Windows workstation. The user says that 255.255.255.0 is not being accepted in the prefix length box. Should the user open a different dialog to complete the configuration or enter a different value?

• Enter a different value

• 255.255.255.0 is not a correct subnet mask

• The user shouldn't need to enter a subnet mask into the configuration menu

• The user can use the Network & Interface settings, Edit IP settings dialog

You are supporting a user who has just replaced a wireless router. The user has joined the new wireless network successfully but can no longer find other computers on the network. What should you check first?

• Check the network profile type using Network & Internet

• Check the IP address information using Network Settings

• Check the router power cable

• Reboot the router and modem

True or false? Windows Defender Firewall cannot be enabled

• True

• False

You need to set up a VPN connection on a user’s Windows laptop. The VPN type is IKEv2. What other information, if any, do you need to configure the connection?

• FQDN or VPN Server IP Address

• FQDN

• VPN Server IP Address

• Domain Controller IP Address

A DHCP server has been reconfigured to use a new network address scheme following a network problem. What command would you use to refresh the IP configuration on Windows client workstations?

• ipconfig /release

• ipconfig /renew

• ipconfig

• configip

A computer cannot connect to the network. The machine is configured to obtain a TCP/IP configuration automatically. You use ipconfig to determine the IP address and it returns 0.0.0.0. What does this tell you?

• The DHCP server is failing

• Something is wrong with the networking software installed on the machine

• This is normal behavior. When a DHCP server can't be reached a Windows PC uses the 0.0.0.0 address

• None of the above

You are pinging a host at 192.168.0.99 from a host at 192.168.0.200. The response is “Reply from 192.168.0.200: Destination host unreachable.” The hosts use the subnet mask 255.255.255.0. Does the ping output indicate a problem with the default gateway?

• Yes

• No

You are checking that a remote Windows workstation will be able to dial into a web conference with good quality audio/video. What is the best tool to use to measure latency between the workstation’s network and the web conferencing server?

• ping

• tracert

• pathping

• ipconfig /trace

Which command produces the output shown in this screenshot?

• Ping

• Tracert

• Netstat

• This is DNS data
