IT Essentials (ITE v7.0) Chapter 6
The current IP configuration of a small company is done manually and is time-consuming. Because of increased network growth, a technician needs a simpler way for IP configuration of workstations. Which service would simplify the workstation IP configuration task?
DHCP*
Port triggering has been configured on a wireless router. Port 25 has been defined as the trigger port and port 113 as an open port. What effect does this have on network traffic?
All traffic that is sent out port 25 will open port 113 to allow inbound traffic into the internal network through port 113.*
A wired network is undergoing several changes that could leave it vulnerable to connection by unauthorized devices while the work is in progress. Which two temporary measures would enable the authorized devices to continue to have network access but prevent unauthorized devices from connecting? (Choose two.)
Disable DHCP.* Assign static IP addresses to the authorized devices.*
A user can print to a printer that is on the same network, but the traffic of the user cannot reach the Internet. What is a possible cause of the problem?
The PC default gateway address is missing or incorrect.*
What two default wireless router settings can affect network security? (Choose two.)
The SSID is broadcast.* A well-known administrator password is set.*
A technician is troubleshooting a problem where the user claims access to the Internet is not working, but there was access to the Internet the day before. Upon investigation, the technician determines that the user cannot access the network printer in the office either. The network printer is on the same network as the computer. The computer has 169.254.100.88 assigned as an IP address. What is the most likely problem?
The computer cannot communicate with a DHCP server.*
A PC is not able to connect to a wired network. Pinging the loopback address is successful, but the gateway cannot be reached. On the network switch all the interface lights are on, except for the interface connected to the PC. The LED on the network card is off. What is the most likely cause of this problem?
The network cable is faulty.*
Users in a recently installed wireless network are complaining of slow data transfer and frequent loss of connectivity. The technician checks that the wireless security is correctly implemented, and there is no evidence of unauthorized users on the network. Which two problems might the technician suspect? (Choose two.)
There is interference from outside sources.* The wireless signal is too weak.*
A network technician is checking a computer to see if the DHCP client is working correctly. The technician issues the ipconfig /all command. Which two parameters should the technician review? (Choose two.)
default gateway* subnet mask *
