Identify the correct cloud deployment model

Which cloud deployment model allows multiple organizations to share infrastructure but keeps data isolated for each?

A Private cloud

B Community cloud

C Public cloud

D Hybrid cloud

💡 Hint

Think about a cloud shared by organizations with similar needs.

A community cloud is shared by several organizations with common concerns, providing shared infrastructure but isolated data.

❓ Architecture

Choose the best AWS service for a private cloud setup

You want to create a private cloud environment on AWS that isolates your resources from other customers. Which AWS service fits this requirement best?

A Amazon VPC with private subnets

B AWS Lambda functions

C Amazon S3 public buckets

D Amazon EC2 instances in a public subnet

💡 Hint

Consider network isolation within AWS.

Amazon VPC allows you to create a private network isolated from other AWS customers, suitable for private cloud setups.

Behavior of hybrid cloud in AWS

In a hybrid cloud setup using AWS, which behavior correctly describes data flow between on-premises data center and AWS cloud?

A Data is stored only on AWS cloud with no on-premises access

B Data flows only from AWS cloud to on-premises with no return path

C Data flows bidirectionally between on-premises and AWS cloud using VPN or Direct Connect

D Data flows only within on-premises network without AWS involvement

💡 Hint

Think about secure connections linking both environments.

Hybrid cloud setups use secure connections like VPN or AWS Direct Connect to enable two-way data flow between on-premises and AWS cloud.

❓ security

advanced

Security best practice in hybrid cloud deployment

Which security practice is most important when managing a hybrid cloud environment?

A Encrypting data in transit between on-premises and cloud environments

B Using the same firewall rules for both on-premises and cloud without changes

C Disabling all network monitoring to improve performance

D Allowing unrestricted access between cloud and on-premises networks

💡 Hint

Think about protecting data moving between environments.

Encrypting data in transit ensures data is secure when moving between on-premises and cloud, which is critical in hybrid cloud security.

Optimizing cost in hybrid cloud architecture

You manage a hybrid cloud with AWS and on-premises servers. Which approach best optimizes cost while maintaining performance?

A Keep all workloads on-premises to avoid cloud costs

B Run all workloads in AWS cloud to eliminate on-premises expenses

C Duplicate all workloads in both environments for maximum availability

D Use AWS for variable workloads and on-premises for steady workloads to balance cost and performance

💡 Hint

Consider workload patterns and cost efficiency.

Using AWS for variable workloads leverages cloud scalability and paying only for what you use, while steady workloads on-premises can reduce cloud costs, balancing cost and performance.
