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 serverโ€™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 userโ€™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
