Questions and Answers

1.

TCP/IP is installed on each PC within a network. You can communicate within the network but are unable to access the Internet. Which of the following TCP/IP settings must be properly configured for Internet access?
- A.
  
  IP Address
- B.
  
  MAC address
- C.
  
  Default Gateway
- D.
  
  DNS Server
- E.
  
  SubNet Mask
Correct Answer(s)
A. IP Address
C. Default Gateway
D. DNS Server
E. SubNet Mask

Explanation
To access the Internet, the IP Address, Default Gateway, DNS Server, and Subnet Mask must be properly configured. The IP Address is necessary to identify the device within the network and the Default Gateway is required to connect the network to the Internet. The DNS Server is responsible for translating domain names into IP addresses, allowing access to websites. The Subnet Mask helps determine the network and host portions of the IP address. Therefore, all of these settings must be correctly configured for Internet access.

What does Safe Mode permit you to do?
- A.
  
  Run Windows without processing AUTOEXEC.BAT and CONFIG.SYS
- B.
  
  Boot the system without formatting drives
- C.

- D.
  
  Start the computer in a DOS environment
Correct Answer
C. Start Windows using only basic files and drives

Explanation
Safe Mode allows you to start Windows using only basic files and drives. This mode disables unnecessary programs and services, making it easier to troubleshoot and fix any issues that may be causing problems with the normal operation of the computer. By running in Safe Mode, you can isolate and identify the source of the problem and take appropriate actions to resolve it.

What command can you enter at a DOS Prompt to check if the computer is communicating to other computers over the network?
- A.
  
  Ipconfig /all
- B.
  
  Nslookup
- C.
  
  Ping
- D.
  
  Format
- E.
  
  Prompt

C. Ping

Explanation
The "ping" command is used to check if the computer is communicating to other computers over the network. It sends a small packet of data to a specific IP address or domain name and waits for a response. If the computer receives a response, it means that it is successfully communicating with the other computer.

What is the maximum length of CAT5 cables?
- A.
  
  100 meters
- B.
  
  200 meters
- C.
  
  300 meters
- D.
  
  400 meters
- E.
  
  500 meters
Correct Answer
A. 100 meters

Explanation
CAT5 cables are commonly used for Ethernet networking. The maximum length of CAT5 cables is 100 meters. This is because beyond this length, the signal strength starts to degrade, causing data loss and reduced network performance. To ensure reliable and efficient data transmission, it is recommended to use repeaters or switches to extend the network beyond 100 meters.

What RAID level has three or more drives for redundancy?
- A.
  
  RAID 0
- B.
  
  RAID 1
- C.
  
  RAID 3
- D.
  
  RAID 4
- E.
  
  RAID 5
Correct Answer
E. RAID 5

Explanation
RAID 5 is the correct answer because it is a RAID level that requires at least three drives for redundancy. In RAID 5, data is striped across multiple drives with distributed parity, which means that if one drive fails, the data can be reconstructed using the parity information stored on the other drives. This provides redundancy and fault tolerance, making RAID 5 a popular choice for data protection in systems with three or more drives.

What connector is used on CAT5 cables?
- A.
  
  RJ-5
- B.
  
  RJ-6
- C.
  
  RJ-11
- D.
  
  RJ-12
- E.
  
  RJ-45
Correct Answer
E. RJ-45

Explanation
CAT5 cables use RJ-45 connectors. RJ-45 is a registered jack connector commonly used for Ethernet connections. It has eight pins and is designed to connect network devices such as computers, routers, and switches. The RJ-45 connector is compatible with CAT5, CAT5e, and CAT6 cables, which are commonly used for wired Ethernet networks.

Explanation
RJ-11 is the correct answer because it is the type of connector commonly used on telephone line modem cables. RJ-11 connectors have four or six pins and are used for connecting telephones, fax machines, and modems to telephone lines. They are smaller in size compared to RJ-45 connectors, which are used for Ethernet cables.
