D) Physical servers, remotely managed by the customer

A) Virtual Servers in the Cloud

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change.

For more information on EC2 instances visit the below link: https://aws.amazon.com/ec2/

Which of the following options of AWS RDS allows for AWS to failover to a secondary database in case the primary one fails?

A) AWS Multi-AZ
B) AWS Failover
C) AWS Secondary
D) AWS Standby

A) AWS Multi-AZ

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for Database (DB) Instances, making them a natural fit for production database workloads. When you provision a Multi-AZ DB Instance, Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). Each AZ runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby (or to a read replica in the case of Amazon Aurora), so that you can resume database operations as soon as the failover is complete.

What service from AWS can help manage the costs for all resources in AWS?

A) Cost Explorer
B) Cost Allocation Tags

Cost Explorer is a free tool that you can use to view your costs. You can view your costs as either a cash-based view (costs are recorded when cash is received or paid) with unblended costs or as an accrual-based view (costs are recorded when income is earned or costs are incurred). You can view data for up to the last 13 months, forecast how much you are likely to spend for the next three months, and get recommendations for what Reserved Instances to purchase.
