All the MCQs for AWS CCP with the answers and a short explanation here:
Question 1: Which phase of the cloud transformation journey does identifying and prioritizing measurable business outcomes belong to?
Options:
A. Scale
B. Align
C. Envision
D. Launch
Correct Answer: C. Envision
Explanation:
The Envision phase of the AWS Cloud Adoption Framework focuses on identifying and prioritizing transformation opportunities to align with strategic business objectives. It helps organizations demonstrate how the cloud can accelerate business outcomes. Other phases like Align, Scale, and Launch deal with different aspects of cloud readiness and implementation.
Question 2: Which AWS service automates the creation, management, and deployment of customized Amazon EC2 server images?
Options:
A. AWS Well-Architected Tool
B. EC2 Image Builder
C. AWS Compute Optimizer
D. AWS Launch Wizard
Correct Answer: B. EC2 Image Builder
Explanation:
EC2 Image Builder is a managed service that automates the creation of updated and secure server images. It supports pipelines for image updates and system patching, making it ideal for managing EC2 server images. Other options like AWS Well-Architected Tool focus on best practices, and AWS Compute Optimizer focuses on resource utilization recommendations.
Question 3: How can a company rightsize its under-utilized EC2 instances with the least operational overhead?
Options:
A. Reserve compute capacity for Amazon EC2 instances through On-Demand Capacity Reservations.
B. Change instance purchasing options to EC2 Instance Savings Plans.
C. Utilize the AWS Compute Optimizer and apply recommended reconfigurations.
D. Deploy an Auto Scaling Group behind an Elastic Load Balancer.
Correct Answer: C. Utilize the AWS Compute Optimizer and apply recommended reconfigurations.
Explanation:
AWS Compute Optimizer provides recommendations for reconfiguring AWS resources to optimize performance and minimize cost. It analyzes usage metrics and suggests the best configurations. Other options, like Auto Scaling Groups, don’t inherently optimize individual instance configurations.
Question 4: Which task can be performed by AWS security groups?
Options:
A. Apply a stateful firewall to an Amazon S3 bucket.
B. Enhance the security of cached data managed by Amazon CloudFront.
C. Prevent unauthorized access from malicious IP addresses at each tier's subnet.
D. Enable exclusive access to Amazon EC2 instances inside an Amazon VPC via a specific port.
Correct Answer: D. Enable exclusive access to Amazon EC2 instances inside an Amazon VPC via a specific port.
Explanation:
Security groups are stateful firewalls attached to resources (e.g., EC2 instances) that allow or deny access through specific ports. They don’t work at the subnet level or protect S3 buckets and CloudFront; those require other AWS tools like Network ACLs or AWS WAF.
Question 5: Which AWS Well-Architected Framework pillar supports the design principle of performing operations as code?
Options:
A. Performance Efficiency
B. Operational Excellence
C. Security
D. Cost Optimization
Correct Answer: B. Operational Excellence
Explanation:
The Operational Excellence pillar emphasizes automating operations and managing infrastructure as code. This approach ensures consistent and repeatable processes. Other pillars like Performance Efficiency and Security focus on different aspects of cloud workload optimization.
Question 6: What is the MOST suitable AWS tool for applying security rules at the subnet level?
Options:
A. AWS Network Firewall
B. AWS Firewall Manager
C. Security Groups
D. Network Access Control Lists (NACLs)
Correct Answer: D. Network Access Control Lists (NACLs)
Explanation:
Network ACLs operate at the subnet level and allow or deny traffic based on rules. Security groups operate at the resource level, while AWS Network Firewall and Firewall Manager are more comprehensive tools for higher-level security management.
Question 7: Which AWS service should be used to streamline native iOS application development?
Options:
A. AWS App Runner
B. AWS Amplify
C. Amazon EC2 M1 Mac instances
D. AWS Device Farm
Correct Answer: C. Amazon EC2 M1 Mac instances
Explanation:
Amazon EC2 M1 Mac instances provide macOS environments for iOS app development. They enable developers to build and test iOS apps in the cloud. Other services, like AWS Amplify, focus on backend services, while AWS Device Farm is for testing apps, not development.
Question 8: What type of migration best describes moving on-premises workloads to a hybrid cloud architecture?
Options:
A. Hybrid to On-premises
B. On-premises to Hybrid
C. Hybrid to Cloud Native
D. On-premises to Cloud Native
Correct Answer: B. On-premises to Hybrid
Explanation:
A hybrid cloud architecture integrates on-premises infrastructure with cloud services, allowing workloads to run in both environments. This migration type is ideal for companies needing low-latency access to local data while leveraging cloud scalability.
Question 9: Which stakeholders are most relevant to the Platform perspective of the AWS Cloud Adoption Framework? (Select TWO)
Options:
A. Chief Information Security Officer (CISO)
B. Chief Financial Officer (CFO)
C. Chief Information Officer (CIO)
D. Technology Leaders
E. IT Architects
Correct Answers: D. Technology Leaders and E. IT Architects
Explanation:
The Platform perspective focuses on delivering scalable and secure cloud workloads. Stakeholders like Technology Leaders and IT Architects play critical roles in designing and managing cloud platforms.
Question 10: Which AWS service allows you to train machine learning models using SQL commands within a data warehouse?
Options:
A. Amazon MemoryDB for Redis
B. Amazon Redshift ML
C. Amazon Quantum Ledger Database (QLDB)
D. Amazon SageMaker
Correct Answer: B. Amazon Redshift ML
Explanation:
Amazon Redshift ML integrates machine learning capabilities into Redshift data warehouses, enabling users to build, train, and deploy ML models using SQL commands. SageMaker is a broader ML service, and QLDB is a ledger database.
Question 11: What is the best way to increase the resilience of a business-critical application hosted on a single Amazon EC2 instance?
Options:
A. Launch multiple EC2 instances in multiple Availability Zones.
B. Launch multiple EC2 instances using CloudFormation StackSets in different AWS accounts.
C. Launch multiple EC2 instances in multiple VPCs.
D. Launch multiple EC2 instances in multiple subnets.
Correct Answer: A. Launch multiple EC2 instances in multiple Availability Zones.
Explanation:
Deploying EC2 instances across multiple Availability Zones ensures high availability and fault tolerance. Other options, like using multiple VPCs or accounts, add unnecessary complexity.
Question 12: Which AWS service uses machine learning to detect unusual cloud expenditures?
Options:
A. Amazon Lookout for Metrics
B. AWS Cost Anomaly Detection
C. AWS Billing Conductor
D. Amazon Forecast
Correct Answer: B. AWS Cost Anomaly Detection
Explanation:
AWS Cost Anomaly Detection uses machine learning to monitor and detect irregular spending patterns. It helps users manage costs effectively and take corrective actions.
