These accelerators reduce hundreds of manual procedures into just a few steps, so you can build your production environment quickly and start using it immediately.
Each Quick Start includes AWS CloudFormation templates that automate the deployment and a guide that discusses the architecture and provides step-by-step deployment instructions.
2. What AWS service would you use in order to serve a static website ?
You can host a static website on Amazon S3.
To host a static website, you configure an Amazon S3 bucket for website hosting, and then upload your website content to the bucket. This bucket must have public read access. It is intentional that everyone in the world will have read access to this bucket.
3. Which of the following represents a valid option that you can search software listings that runs on AWS Cloud Platform?
AWS Marketplace is a digital catalog with thousands of software listings from independent software vendors that make it easy to find, test, deploy and buy software compatible to run on AWS.
4. What is the lowest cost, durable storage option for retaining database backups, for immediate retrieval ?
S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed.
This combination of low cost and high performance make S3 Standard-IA ideal for long-term storage, backups, and as a data store for disaster recovery files
5. Which of the following features are available for configuration through the Amazon VPC Dashboard ?
Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define.
You have complete control over your virtual networking environment, including
- selection of your own IP address range
- creation of subnets
- configuration of route tables and network gateways
6. Which AWS service would you choose in order to manage infrastructure as code ?
AWS CloudFormation is a service that helps you model and set up your Amazon Web Services resources
You create a template that describes all the AWS resources that you want (like Amazon EC2 instances or Amazon RDS DB instances), and AWS CloudFormation takes care of provisioning and configuring those resources for you.
Codifying your infrastructure allows you to treat your infrastructure as just code. You can author it with any code editor, check it into a version control system, and review the files with team members before deploying into production
7. Which AWS service would you choose in order to connect your on-premises data center to an Amazon VPC ?
AWS Direct Connect links your internal network to an AWS Direct Connect location over a standard Ethernet fiber-optic cable.
One end of the cable is connected to your router, the other to an AWS Direct Connect router.
With this connection, you can create virtual interfaces directly to public AWS services (for example, to Amazon S3) or to Amazon VPC, bypassing internet service providers in your network path
8. Which of the following AWS services run at global level instead of regional ?
- AWS IAM
- Amazon Route 53
- Amazon CloudFront
- Amazon S3
run at the global level, they don’t require region selection.
9. Which AWS service can help you get access to compliance reports and certificates ?
AWS Artifact provides on-demand downloads of AWS security and compliance documents, such as AWS ISO certifications, Payment Card Industry (PCI), and Service Organization Control (SOC) reports.
You can submit the security and compliance documents (also known as audit artifacts) to your auditors or regulators to demonstrate the security and compliance of the AWS infrastructure and services that you use.
You can also use these documents as guidelines to evaluate your own cloud architecture and assess the effectiveness of your company’s internal controls.
10. Which AWS service provides information and alerts about AWS events that may impact the performance of services in your AWS account?
The AWS Personal Health Dashboard provides information about AWS Health events that can affect your account.
The information is presented in two ways: a dashboard that shows recent and upcoming events organized by category, and a full event log that shows all events from the past 90 days.
11. Which of the following represents an advantage of Amazon Relational Database Service (RDS) ?
Amazon RDS makes it easy to go from project conception to deployment. You can access the capabilities of a production-ready relational database in minutes.
No need for infrastructure provisioning, and no need for installing and maintaining database software.
12. Which of the following represent AWS CloudWatch benefits ?
- Collect metrics & logs of your running AWS resource
- Data Retention is adjustable, as you need
- Real-time, automatic dashboard for monitoring
- Set alarm & automate action based on predefined events
13. Which of the following AWS services would you use in order to audit the change management of AWS resources ?
AWS Config provides a detailed view of the configuration of AWS resources in your AWS account.
This includes how the resources are related to one another and how they were configured in the past so that you can see how the configurations and relationships change over time
14. One of your servers in AWS is not responsive anymore. You decide to investigate and find out that the server has been stopped for patching by your DevOps team.
Which AWS service would you use in order to find out which user has stopped the server ?
AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account.
Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail.
Events include actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs.
CloudTrail is enabled on your AWS account when you create it. When activity occurs in your AWS account, that activity is recorded in a CloudTrail event. You can easily view recent events in the CloudTrail console by going to Event history.
15. Which AWS services are part of AWS serverless platform ?
- AWS Lambda
- AWS Step Functions
- AWS Glue
16. Which of the following services is under customer’s responsibility to maintain operating system configuration, patching and networking?
Amazon EC2
17. Which of the following are characteristics of Amazon S3 ?
S3 is a global service, But you need to specify an AWS Region when you create an Amazon S3 bucket.
Within each AWS Region, S3 operates in a minimum of three AZs (not two).
S3 is object storage designed for 99.999999999% (11 9s) availability
18. Which of the following data archival AWS service is very cheap, but has a long time multi-hour data-retrieval ?
Amazon S3 Glacier
19. Which of the following represent valid options of data arriving in Amazon Glacier ?
Glacier provides a management console. You can use the console to create and delete vaults.
However, all other interactions with Glacier require that you use the AWS Command Line Interface (CLI) or write code.
For example, to upload data, such as photos, videos, and other documents, you must either use the AWS CLI or write code to make requests, using either the REST API directly or by using the AWS SDKs.
20. Which AWS service would you use in order to quickly deploy resources that support different programming languages ?
With Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without having to learn about the infrastructure that runs those applications.
Elastic Beanstalk reduces management complexity without restricting choice or control. You simply upload your application, and Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.
Elastic Beanstalk supports applications developed in Go, Java, .NET, Node.js, PHP, Python, and Ruby.
When you deploy your application, Elastic Beanstalk builds the selected supported platform version and provisions one or more AWS resources, such as Amazon EC2 instances, to run your application.
21. Which of the following constructs encompass or host EC2 instances ?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.
Amazon VPC is the networking layer for Amazon EC2.
