CLF-C01 : AWS Certified Cloud Practitioner : Part 10

Which of the following services is a MySQL-compatible database that automatically grows storage as needed?
- Amazon Elastic Compute Cloud (Amazon EC2)
- Amazon Relational Database Service (Amazon RDS) for MySQL
- Amazon Lightsail
- Amazon Aurora
Explanation:
Amazon Aurora is a relational database service that combines the speed and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. The MySQL-compatible edition of Aurora delivers up to 5X the throughput of standard MySQL running on the same hardware, and enables existing MySQL applications and tools to run without requiring modification. Amazon Aurora will automatically grow the size of your database volume as your database storage needs grow. Your volume will grow in increments of 10 GB up to a maximum of 64 TB. You don’t need to provision excess storage for your database to handle future growth.
Which Amazon Virtual Private Cloud (Amazon VPC) feature enables users to connect two VPCs together?
- Amazon VPC endpoints
- Amazon Elastic Compute Cloud (Amazon EC2) ClassicLink
- Amazon VPC peering
- AWS Direct Connect
Explanation:
A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, or with a VPC in another AWS account. The VPCs can be in different regions (also known as an inter-region VPC peering connection).
Which service’s PRIMARY purpose is software version control?
- Amazon CodeStar
- AWS Command Line Interface (AWS CLI)
- Amazon Cognito
- AWS CodeCommit
Explanation:
AWS Code Commit is a version control service hosted by Amazon Web Services that you can use to privately store and manage assets (such as documents, source code, and binary files) in the cloud.
A company is considering migrating its applications to AWS. The company wants to compare the cost of running the workload on-premises to running the equivalent workload on the AWS platform.

Which tool can be used to perform this comparison?
- AWS Simple Monthly Calculator
- AWS Total Cost of Ownership (TCO) Calculator
- AWS Billing and Cost Management console
- Cost Explorer
Explanation:
TCO calculator compare the cost of running your applications in an on-premises or colocation environment to AWS.
Which AWS service provides a secure, fast, and cost-effective way to migrate or transport exabyte-scale datasets into AWS?
- AWS Batch
- AWS Snowball
- AWS Migration Hub
- AWS Snowmobile
Explanation:
AWS Snowmobile is an exabyte-scale data transfer service that can move extremely large amounts of data to AWS in a fast, secure, and cost-effective manner. You can transfer up to 100PB per Snowmobile, a 45-foot long ruggedized shipping container, pulled by a semi-trailer truck. Snowmobile makes it easy to move massive volumes of data to the cloud, including video libraries, image repositories, or even a complete data center migration. All data is encrypted with 256-bit encryption and you can manage your encryption keys with AWS Key Management Service (AWS KMS). Snowmobile includes GPS tracking, alarm monitoring, 24/7 video surveillance and an optional escort security vehicle while in transit.
Which of the following BEST describe the AWS pricing model? (Choose two.)
- Fixed-term
- Pay-as-you-go
- Colocation
- Planned
- Variable cost
Which load balancer types are available with Elastic Load Balancing (ELB)? (Choose two.)
- Public load balancers with AWS Application Auto Scaling capabilities
- F5 Big-IP and Citrix NetScaler load b
- Classic Load Balancers
- Cross-zone load balancers with public and private IPs
- Application Load Balancers
Explanation:
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use either type of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic. Network Load Balancers and Classic Load Balancers are used to route TCP (or Layer 4) traffic.
Why should a company choose AWS instead of a traditional data center?
- AWS provides users with full control over the underlying resources.
- AWS does not require long-term contracts and provides a pay-as-you-go model.
- AWS offers edge locations in every country, supporting global reach.
- AWS has no limits on the number of resources that can be created.
Explanation:
AWS offers you a pay-as-you-go approach for pricing for over 160 cloud services. With AWS you pay only for the individual services you need, for as long as you use them, and without requiring long-term contracts or complex licensing. AWS pricing is similar to how you pay for utilities like water and electricity. You only pay for the services you consume, and once you stop using them, there are no additional costs or termination fees.
Which solution provides the FASTEST application response times to frequently accessed data to users in multiple AWS Regions?
- AWS CloudTrail across multiple Availability Zones
- Amazon CloudFront to edge locations
- AWS CloudFormation in multiple regions
- A virtual private gateway over AWS Direct Connect
Explanation:
You can deliver content and decrease end-user latency of your web application using Amazon CloudFront. CloudFront speeds up content delivery by leveraging its global network of data centers, known as edge locations, to reduce delivery time by caching your content close to your end users. CloudFront fetches your content from an origin, such as an Amazon S3 bucket, an Amazon EC2 instance, an Amazon Elastic Load Balancing load balancer or your own web server, when it’s not already in an edge location. CloudFront can be used to deliver your entire website or application, including dynamic, static, streaming, and interactive content.
Which AWS service provides a self-service portal for on-demand access to AWS compliance reports?
- AWS Config
- AWS Certificate Manager
- Amazon Inspector
- AWS Artifact
Explanation:
AWS Artifact is your go-to, central resource for compliance-related information that matters to you. It provides on-demand access to AWS’ security and compliance reports and select online agreements. Reports available in AWS Artifact include our Service Organization Control (SOC) reports, Payment Card Industry (PCI) reports, and certifications from accreditation bodies across geographies and compliance verticals that validate the implementation and operating effectiveness of AWS security controls. Agreements available in AWS Artifact include the Business Associate Addendum (BAA) and the Nondisclosure Agreement (NDA).
Which of the following AWS services can be used to run a self-managed database?
- Amazon Route 53
- AWS X-Ray
- AWS Snowmobile
- Amazon Elastic Compute Cloud (Amazon EC2)
What exclusive benefit is provided to users with Enterprise Support?
- Access to a Technical Project Manager
- Access to a Technical Account Manager

How can a user protect against AWS service disruptions if a natural disaster affects an entire geographic area?
- Deploy applications across multiple Availability Zones within an AWS Region.
- Use a hybrid cloud computing deployment model within the geographic area.
- Deploy applications across multiple AWS Regions.
- Store application artifacts using AWS Artifact and replicate them across multiple AWS Regions.
Explanation:
An AWS Region is a geographic location where AWS provides multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking.
How does AWS MOST effectively reduce computing costs for a growing start-up company?
- It provides on-demand resources for peak usage.
- It automates the provisioning of individual developer environments.
- It automates customer relationship management.
- It implements a fixed monthly computing budget.
Explanation:
You can continue to optimize your spend and keep your development costs low by making sure you revisit your architecture often, to adjust to your startup growth. Manage your cost further by leveraging different options such as S3 CloudFront for caching & offloading to reduce cost of EC2 computing, as well as Elastic Load Balancing which prepares you for massive scale, high reliability and uninterrupted growth. Another way to keep costs down is to use AWS Identity and Access Management solutions (IAM) to manage governance of your cost drivers effectively and by the right teams.
A startup is working on a new application that needs to go to market quickly. The application requirements may need to be adjusted in the near future.

Which of the following is a characteristic of the AWS Cloud that would meet this specific need?
