The physical server loses processing power

Network cables become loose

Virtual memory usage increases

Submit

4. Which of the following is a security best practice for virtual machine access?

Use strong authentication and disable unnecessary network services

Enable all network services for convenience

Share VM credentials among team members

Disable firewalls on internal VMs

5. True or False: Virtual network segregation using VLANs can help limit lateral movement between compromised VMs.

True

False

6. What security risk does an unpatched hypervisor pose to the entire virtual infrastructure?

It can be exploited to compromise all VMs on that host

It only affects individual VM performance

It increases network bandwidth usage

It requires more physical memory

Submit

8. Which administrative practice reduces security risks in virtualized environments?

Role-based access control and separation of duties

Giving all administrators full system access

Disabling audit logging

Allowing shared credentials across multiple accounts

9. True or False: Virtual machine templates should contain hardened configurations and security baselines before deployment.

True

False

10. What is the security risk of sharing storage between multiple virtual machines without proper access controls?

Unauthorized access to another VM's data

Increased CPU performance

Reduced network latency

Lower power consumption

11. What is the primary security risk when multiple virtual machines share a single physical hypervisor?

VM escape and potential cross-VM compromise

Increased power consumption

Slower network speeds

Higher licensing costs

12. Which security measure should be implemented to protect sensitive data stored in virtual machine disk files?

Full disk encryption at the VM level

Storing VMs on public cloud servers

Disabling antivirus software on VMs

Using default passwords for all VMs

13. What is a primary advantage of using resource limits in a virtualized environment?

Prevents one VM from monopolizing resources and impacting others

Eliminates the need for backup solutions

Automatically patches all VMs

Reduces software licensing fees

14. True or False: A Type 2 hypervisor running on a compromised host OS is inherently more secure than a Type 1 hypervisor.

True

False

Submit

16. What security risk is associated with VM sprawl?

Unmanaged VMs become difficult to patch and monitor

Physical servers consume more electricity

Virtual networks operate at slower speeds

Hypervisors require more RAM

17. Which of the following is a security best practice for virtual machine snapshots?

Store snapshots in an unsecured backup location

Delete snapshots regularly and store them securely

Keep all snapshots indefinitely for quick rollback

Share snapshot files across all VM administrators

Submit

19. What does VM isolation protect against in a virtualized environment?

One VM interfering with another VM's resources or data

Physical disk failures

Network bandwidth limitations

User login timeouts

20. Which security vulnerability allows an attacker to break out of a VM and access the host system or other VMs?

VM escape

Privilege escalation

Man-in-the-middle attack

Denial of service
