Cloud Computing Security Quiz

Which security measure prevents unauthorized data access between tenants in cloud computing?

• Data isolation

• Resource overcommitment

• Load balancing

• Hardware scaling

The "heartbeat" mechanism in Hypervisor Clustering is used to:

• Monitor storage usage across the cluster

• Check the availability of active hypervisors

• Verify data encryption in virtual machines

• Test application speed under cloud load

What is the primary advantage of virtualization in cloud computing?

• Improves local server performance

• Enhances resource utilization

• Eliminates internet dependencies

• Reduces storage costs

Which of the following best describes a Denial of Service (DoS) attack?

• It encrypts data and demands a ransom

• It exploits virtualization vulnerabilities

• It floods cloud resources with excessive requests to make them unavailable

• It creates duplicate data in a cloud environment

Which type of ISP owns the global backbone infrastructure?

• Tier 2 ISPs

• Tier 1 ISPs

• Local ISPs

• Tier 3 ISPs

Redundant Physical Connection Architecture helps to:

• Maintain network connectivity if NIC fails

• Isolate user traffic for analysis

• Extend memory virtualization

• Automate database migration

What is the definition of virtualization in cloud computing?

• The process of securing cloud data from threats

• A type of cloud deployment model

• The creation of virtual versions of physical hardware using software

• Using multiple physical servers to create one virtual machine

In hardware-based virtualization, the hypervisor is installed:

• Inside an application

• Directly on the hardware

• On top of another OS

• Only in cloud-based systems

Which strategy in capacity planning adds resources before demand increases?

• Lag Strategy

• Lead Strategy

• Incremental Strategy

• Match Strategy

In a system with an Active-Passive configuration, what happens when the primary service fails?

• SLA metrics trigger a scaling event

• Nothing happens, the system stops

• The passive instance becomes active

• The same instance restarts
