CompTIA Cloud Computing Fundamentals 3

Question 1

In cloud networking, what is a Virtual Private Cloud (VPC)?

Accepted Answer

An isolated virtual network within a public cloud provider's infrastructure

Answer

A VPC is a logically isolated virtual network within a public cloud provider that allows customers to define their own IP address ranges, subnets, and routing rules.

Question 2

What is 'cloud bursting' in a hybrid cloud architecture?

Accepted Answer

Automatically scaling overflow workloads from private to public cloud during peak demand

Answer

Cloud bursting allows an application running in a private cloud to automatically scale into public cloud resources when on-premises capacity is insufficient to handle peak demand.

Question 3

Which cloud computing concept ensures that cloud resources are shared among multiple customers while keeping each customer's data logically separated?

Accepted Answer

Multi-tenancy

Answer

Multi-tenancy allows multiple customers (tenants) to share the same physical infrastructure while their data and applications remain logically isolated from one another.

Question 4

A cloud administrator needs to define and manage infrastructure using configuration files rather than manual processes. What practice does this describe?

Accepted Answer

Infrastructure as Code (IaC)

Answer

Infrastructure as Code (IaC) involves managing and provisioning cloud infrastructure through machine-readable configuration files, enabling automation, consistency, and version control.

Question 5

Which Service Level Agreement (SLA) metric describes the percentage of time a cloud service is operational and accessible?

Accepted Answer

Uptime/Availability percentage

Answer

Cloud SLAs define availability as the percentage of time the service is operational, commonly expressed as '99.9% uptime,' meaning no more than ~8.76 hours of downtime per year.
