1. Your CTO thinks your AWS(Amazon Web Service) account was hacked. What is the only way to know for certain if there was unauthorized access and what they did, assuming your hackers are very sophisticated AWS(Amazon Web Service) engineers and doing everything they can to cover their tracks?

A) Use Cloud Trail Log File Integrity Validation
B) Use AWS(Amazon Web Service) Config SNS Subscriptions and process events in real time.
C) Use AWS(Amazon Web Service) Config Timeline forensics.
D) Use Cloud Trail backed up to AWS(Amazon Web Service) 53 and Glacier



2. You are creating a new API for video game scores. Reads are 100 times more common than writes, and the top 1% of scores are read 100 times more frequently than the rest of the scores. What?s the best design for this system, using Dynamo DB?

A) Dynamo DB table with roughly equal read and write throughput, with Elastic Cache caching.
B) Dynamo DB table with lOOx higher read than write throughput, with Cloud Front caching.
C) Dynamo DB table with roughly equal read and write throughput. with Cloud Front caching
D) Dynamo DB table with bOx higher read than write throughput, with Elastic Cache caching.



3. You are building out a layer in a software stack on AWS(Amazon Web Service) that needs to be able to scale out to react to increased demand as fast as possible. You are running the code on EC2 instances in an Auto Scaling Group behind an ELB. Which application code deployment method should you use? Please select:

A) Create a new Auto Scaling Launch Configuration with User Data scripts configured to pull the latest code at all times.
B) SSH into new instances that come online, and deploy new code onto the system by pulling it from an 53 bucket, which is populated by code that you refresh from source control on new pushes.
C) Create a Docker file when preparing to deploy a new version to production and publish it to 53. Use User Data In the Auto Scaling Launch configuration to pull down the Docker file from S3 and run It when new instances launch.
D) Bake an AMI when deploying new versions of code, and use that AMI for the Auto Scaling Launch Configuration.



4. You need to create a simple, holistic check for your system?s general availability and uptime. Your system presents itself as an HTTP-speaking API. What is the most simple tool on AWS(Amazon Web Service) to achieve this with? Please select:

A) Route53 Health Checks
B) AWS ELB Health Checks
C) EC2 Health Checks
D) Cloud Watch Health Checks



5. Your system automatically provisions ElPs to EC2 instances in a VPC on boot. The system provisions the whole VPC and stack at once. You have two of them per VPC. On your new AWS(Amazon Web Service) account, your attempt to create a Development environment failed, after successfully creating Staging and Production environments in the same region. What happened?

A) You hit the soft limit of S ElPs per region and requested a 6th.
B) You hit the soft limit of 2 VPCs per region and requested a 3rd.
C) You didn?t set the Development flag to true when deploying EC2 instances.
D) You didn?t choose the Development version of the AMI you are using.
