Question 8)
Which of the following statements accurately describes port filtering?

• A firewall function that blocks or allows certain port numbers in order to limit unwanted network traffic
• A security technique that divides a network into segments
• A process performed by a VPN service that protects data by wrapping it in other data packets

• Patch updating
• Cloud hardening

Question 10)
How can a security professional confirm that no unverified changes have occurred within a cloud server?

• Perform a penetration test
• Establish multifactor authentication (MFA)

• Use port filtering to block or allow certain updates

 

Question 11)
When performing security hardening, what is the goal with regards to the attack surface?

• Hide the attack surface
• Augment the attack surface
• Reduce the attack surface

• Packet sniffing
• The Ping of Death
• A Distributed Denial of Service (DDoS) attack
• Penetration testing

 

Question 14)
A security analyst reviews documentation about a firewall rule that includes a list of allowed and disallowed network ports. They compare it to the current firewall to ensure no changes have been made. What does this scenario describe?

• Verifying user identity when accessing an OS
• Checking baseline configuration
• Responsibly managing applications
• Upgrading the interface between computer hardware and the user

Question 16)
In what way might port filtering be used to protect a network from an attack?

• To disable unused ports in order to reduce the attack surface
• To inspect, analyze, and react to security events based on their priority
• To increase the attack surface in a network
• To create isolated subnets for different departments in an organization

Question 17)
What is one key similarity between regular web servers and cloud servers?

• In both, all applications are stored together, regardless of their age.
• They both require proper maintenance and security hardening.
• In both, all data and application are stored together, regardless of their service category.
• They both use baseline images stored in the cloud to compare data.
