Question 3

What can you use as a protective barrier on a network to keep out unauthorized traffic?
A) Firewall
B) Network attached storage (NAS)
C) Encryption
D) Biometric devices

Accepted Answer

A firewall is specifically designed to prevent unauthorized access to a network by acting as a protective barrier between the network and external sources, filtering out incoming traffic and blocking anything that seems suspicious. Network attached storage (NAS) and biometric devices are not specifically designed for this purpose, and while encryption can help protect data, it does not necessarily prevent unauthorized access to the network as a whole.

Question 4

Tori is traveling for a business conference and needs to order a computer part so it will arrive at her hotel before her presentation at the end of the week. To do this, she'll need to enter her credit card number over the hotel's wireless network. How can Tori protect her financial information?
A) Choose a wireless network that uses the hotel's name
B) Make sure the website she orders from is secure
C) Use a VPN connection
D) Use a coffee shop's wireless network instead

Accepted Answer

Using a VPN connection would encrypt Tori's internet traffic, making it more difficult for anyone on the same network to intercept her credit card information. This would provide an additional layer of security for her financial information. Choosing a wireless network based on the hotel's name or using a coffee shop's wireless network would not necessarily ensure the security of her information. While making sure the website she orders from is secure is important, it alone may not be sufficient to protect her credit card number.

Question 5

Which network topology is most likely to continue to function well even if one device fails?
A) Star network

Question 12

Which network type is often used for vendor access?
A) Intranet
B) Intranet..
C) Extranet
D) Wireless network

Accepted Answer

Extranet is often used to provide vendor access as it allows controlled access to a company's internal network to an external user or organization such as vendors, suppliers or customers. It provides a secure platform to use protected company resources while limiting access to sensitive data.

Question 13

Tyler recently discovered that his neighbors have been using his wireless network to stream movies in the evening. This has caused slower network performance for Tyler, who likes to play Internet games after work. What can Tyler do to protect his wireless network from his neighbors?
A) Use a strong password for authentication
B) Add a firewall to the network
C) Change the key on his door
D) Use a VPN

Accepted Answer

Using a strong password for authentication will prevent unauthorized access to Tyler's wireless network. This will ensure that only authorized devices can connect to the network and use its bandwidth. Adding a firewall and using a VPN are also good security measures, but they may add unnecessary complexity to the network and may not be necessary for Tyler's specific situation. Changing the key on his door is not relevant to protecting his wireless network.
