Which AWS managed service is used to host databases?

  • A. AWS Batch
  • B. AWS Artifact
  • C. AWS Data Pipeline
  • D. Amazon RDS

Answer : D

Explanation -
Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups. It frees you to focus on your applications so you can give them the fast performance, high availability, security and compatibility they need.

Which AWS service provides a simple and scalable shared file storage solution for use with Linux-based AWS and on-premises servers?

  • A. Amazon S3
  • B. Amazon Glacier
  • C. Amazon Elastic Block Store (Amazon EBS)
  • D. Amazon Elastic File System (Amazon EFS)

Answer : D

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.
Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for Linux workloads. Throughput and IOPS scale as a file system grows and can burst to higher throughput levels for short periods of time to support the unpredictable performance needs of file workloads. For the most demanding workloads, Amazon EFS can support performance over 10 GB/sec and up to 500,000 IOPS.

When architecting cloud applications, which of the following are a key design principle?

  • A. Use the largest instance possible
  • B. Provision capacity for peak load
  • C. Use the Scrum development process
  • D. Implement elasticity

Answer : D

Cloud services main proposition is to provide elasticity through horizontal scaling. Itג€™s already there. As for using largest instance possible, it is not a design principle that helps cloud applications in anyway. Scrum development process is not related to architecting. Therefore, a key principle is to provision your application for on-demand capacity. Peak loads is something that cloud applications experience everyday. Peak load management should be a necessary part of cloud application design principle.

Which AWS service should be used for long-term, low-cost storage of data backups?

  • A. Amazon RDS
  • B. Amazon Glacier
  • C. AWS Snowball
  • D. AWS EBS

Answer : B

Explanation -
Amazon S3 Glacier is a secure, durable, and low-cost storage class of S3 for data archiving and long-term backup. Customers can store large or small amounts of data for as little as $0.004 per gigabyte per month. The S3 Glacier storage class is ideal for archives where data is regularly retrieved and some of the data may be needed in minutes.
Amazon RDS is a relational database service that hosts databases. It helps you create and manage databases. Amazon Snowball is a petabyte-scale data transfer service that provides cost efficient data transfer to AWS from tamper proof physical devices. Similarly, Elastic block storage offers persistent block storage volumes for EC2 instances.

Under the shared responsibility model, which of the following is a shared control between a customer and AWS?

  • A. Physical controls
  • B. Patch management
  • C. Zone security
  • D. Data center auditing

Answer : B

Which AWS service allows companies to connect an Amazon VPC to an on-premises data center?

  • A. AWS VPN
  • B. Amazon Redshift
  • C. API Gateway
  • D. Amazon Connect

Answer : D

AWS Direct Connect enables you to securely connect your AWS environment to your on-premises data center or office location over a standard 1 gigabit or 10 gigabit Ethernet fiber-optic connection. AWS Direct Connect offers dedicated high speed, low latency connection, which bypasses internet service providers in your network path. An AWS Direct Connect location provides access to Amazon Web Services in the region it is associated with, as well as access to other US regions. AWS Direct Connect allows you to logically partition the fiber-optic connections into multiple logical connections called Virtual Local Area Networks
(VLAN). You can take advantage of these logical connections to improve security, differentiate traffic, and achieve compliance requirements.

A company wants to reduce the physical compute footprint that developers use to run code.
Which service would meet that need by enabling serverless architectures?

  • A. Amazon Elastic Compute Cloud (Amazon EC2)
  • B. AWS Lambda

  • D. AWS CodeCommit

Answer : B

AWS Lambda is an integral part of coding on AWS. It reduces physical compute footprint by utilizing aws cloud services to run code.

Which AWS service provides alerts when an AWS event may impact a companyג€™s AWS resources?

  • A. AWS Personal Health Dashboard
  • B. AWS Service Health Dashboard
  • C. AWS Trusted Advisor
  • D. AWS Infrastructure Event Management
