You need to host a file in a location that's publicly accessible from anywhere in the world. Which AWS service would best meet that need?

• RDS

• EBS

• S3

• EC2

Which of the following is AWS' Data Warehousing service?

• S3 Big Data

• Snowball

• Elastic Map Reduce

• Redshift

You have a mission-critical application which must be globally available at all times. Which deployment strategy should you follow?

• Multi-Availability Zone

• Multi-Region

• Deploy to all Availability Zones in your home region.

• Multi-VPC in two AWS Regions

Which AWS service enables you to store file data as objects in S3 for data lakes, backups, and ML workflows?

• Amazon Elastic Block Store

• Amazon Elastic File System

• Amazon S3

• Storage Gateway

You are put in charge of your company’s Disaster Recovery planning. As part of this plan, you intend to create all of the company infrastructure with CloudFormation templates. The templates can then be saved in another region and used to launch a new environment in case of disaster. What determines the costs associated with CloudFormation templates?

• The distance of the region from the home region.

• There is no cost for templates, but when deployed, the resources created may accumulate charges.

• There is a cost per template and discounts for over 100 templates.

• It depends whether the resources in the template are in the free tier.

You are working for a large financial institution and have been tasked with creating a relational database solution to deal with a read-heavy workload. The database needs to be highly available within the Oregon region and quickly recover if an Availability Zone goes offline. Which of the following would you select to meet these requirements?

• Split your database into multiple RDS instances across different regions. In the event of a failure, point your application to the new region.

• Enable Multi-AZ support for the RDS database.

• Using RDS, create a read replica. If an AZ fails, RDS will automatically cut over to the read replica.

• Use an Amazon Aurora global database to ensure a region failure won't break the application.

• Create a read replica and point your read workloads to the new endpoint RDS provides.

A large, big-box hardware chain is setting up a new inventory management system. They have developed a system using IoT sensors which captures the removal of items from the store shelves in near real-time and want to use this information to update their inventory system. The company wants to analyze this data in the hopes of being ahead of demand and properly managing logistics and delivery of in-demand items.

Which AWS service can be used to capture this data as close to real-time as possible, while being able to both transform and load the streaming data into Amazon S3 or Elasticsearch?

• Amazon Redshift

• Amazon Kinesis Data Firehose

• Amazon Kinesis Data Streams

• Amazon Aurora

A team member has been tasked to configure four EC2 instances for four separate applications. These are not high-traffic apps, so there is no need for an Auto Scaling group. The instances are all in the same public subnet and each instance has an EIP address, and all of the instances have the same security group. But none of the instances can send or receive internet traffic. You verify that all the instances have a public IP address. You also verify that an internet gateway has been configured. What is the most likely issue?

• You are using the default NACL.

• The route table is corrupt.

• Each instance needs its own security group.

• There is no route in the route table to the internet gateway (or it has been deleted).

You have been evaluating the NACLs in your company. Currently, you are looking at the default network ACL. Which statement is true regarding subnets and NACLs?

• Only public subnets can use the default NACL.

• The default NACL will always be associated with each subnet.

• Each subnet in your VPC must be associated with a network ACL. If you don't explicitly associate a subnet with a network ACL, the subnet is automatically associated with the default network ACL.

• You have to delete the default NACL before creating a custom NACL to associate with a subnet.

You are managing S3 buckets in your organization. One of the buckets in your organization has gotten some bizarre uploads and you would like to be aware of these types of uploads as soon as possible. Because of that, you configure event notifications for this bucket. Which of the following is NOT a supported destination for event notifications?

• SES

• SQS

• SNS

• Lambda function
