• Domain name system (DNS)

Question 6)
Which of the following does encapsulation protect?

• public IP addresses
• proxy servers
• data in transit
• cryptographic keys

Question 7)
What network is part of the uncontrolled zone?

• Internal networks
• Web servers
• Subnets
• Internet

What network zone acts as a network perimeter to the internal network by isolating servers that are exposed to the internet?

• Uncontrolled zone
• Demilitarized zone
• Restricted zone
• Virtual private network

Question 9)
A security analyst implements a proxy server to secure internal networks. What are some of the proxy server’s primary functions? Select all that apply.

• Use public IP addresses that are different from the rest on the private network
• Determine whether requests to connect to a website are allowed
• Temporarily stores data that is frequently requested by external servers
• Divide the network into segments to maintain privacy within corporate groups

Question 10)
How do forward proxy servers secure internal networks?

• They are useful for protecting internal web servers that contain confidential data.
• They hide a user’s IP address and approve all outgoing requests.
• Both forward and reverse proxy servers add a layer of protection from the internet.
• They receive outgoing traffic from an employee, approve it, then forward it to its destination on the internet.

A firewall administrator installs a firewall function to either block or allow certain port numbers to limit unwanted communication. What function does this scenario describe?

• Organizing data packets
• Location masking
• Using cloud-based firewalls
• Port filtering

Question 5)
How do VPNs preserve confidentiality?

• Translate internet domain names to IP addresses
• Use temporary memory to store data requested by external servers
• Monitor traffic to and from a network
• Encrypt data in transit

Question 6)
What does a VPN service use to transfer encrypted data between a device and the VPN server?

• encapsulation
• transmission control
• packet sniffing
• network segmentation
