Question 81 of 100

Refer to the architecture diagram of a batch processing solution using Simple Queue Service (SQS) to set up a message queue between EC2 instances, which are used as batch processors. CloudWatch monitors the number of Job requests (queued messages) and an Auto Scaling group adds or deletes batch servers automatically based on parameters set in Cloud Watch alarms. You can use this architecture to implement which of the following features in a cost effective and efficient manner?

AReduce the overall time for executing jobs through parallel processing by allowing a busy EC2 instance that receives a message to pass it to the next instance in a daisy-chain setup.

BImplement fault tolerance against EC2 instance failure since messages would remain in SQS and worn can continue with recovery of EC2 instances implement fault tolerance against SQS failure by backing up messages to S3.

CImplement message passing between EC2 instances within a batch by exchanging messages through SOS.

DCoordinate number of EC2 instances with number of job requests automatically thus Improving cost effectiveness

EHandle high priority jobs before lower priority jobs by assigning a priority metadata field to SQS messages.

Question 82 of 100

Your mission is to create a lights-out datacenter environment, and you plan to use AWS OpsWorks to accomplish this. First you created a stack and added an App Server layer with an instance running in it. Next you added an application to the instance, and now you need to deploy a MySQL RDS database instance. Which of the following answers accurately describe how to add a backend database server to an OpsWorks stack? Choose 3 answers

AAdd a new database layer and then add recipes to the deploy actions of the database and App Server layers.

BUse OpsWorks’ “Clone Stack” feature to create a second RDS stack in another Availability Zone for redundancy in the event of a failure in the Primary AZ. To switch to the secondary RDS instance, set the [:database] attributes to values that are appropriate for your server, which you can do by using custom JSON.

CThe variables that characterize the RDS database connection—host, user, and so on—are set using the corresponding values from the deploy JSON’s [:deploy][:app_name][:database] attributes.

DCookbook attributes are stored in a repository, so OpsWorks requires that the “password”: “your_password” attribute for the RDS instance must be encrypted using at least a 256-bit key.

ESet up the connection between the app server and the RDS layer by using a custom recipe. The recipe configures the app server as required, typically by creating a configuration file. The recipe gets the connection data such as the host and database name from a set of attributes in the stack configuration and deployment JSON that AWS OpsWorks installs on every instance.

Question 84 of 100Multiple Choice

A video-sharing mobile application uploads files greater than 10 GB to an Amazon S3 bucket. However, when using the application in locations far away from the S3 bucket region, uploads take extended periods of time, and sometimes fail to complete. Which combination of methods would improve the performance of uploading to the application? (Select TWO.)

AConfigure an S3 bucket in each region to receive the uploads, and use cross-region replication to copy the files to the distribution bucket.

BModify the application to add random prefixes to the files before uploading.

CSet up Amazon Route 53 with latency-based routing to route the uploads to the nearest S3 bucket region.

DEnable S3 Transfer Acceleration on the S3 bucket, and configure the application to use the Transfer Acceleration endpoint for uploads.

EConfigure the application to break the video files into chunks and use a multipart upload to transfer files to Amazon S3.

Question 85 of 100

A company has developed a Ruby on Rails content management platform. Currently, OpsWorks with several stacks for dev, staging, and production is being used to deploy and manage the application. Now, the company wants to start using Python instead of Ruby. How should the company manage the new deployment such that it should be able to revert back to the old application with Ruby if the new deployment starts adversely impacting the existing customers?

ACreate a new stack that contains the Python application code and manages separate deployments of the application via the secondary stack using the deploy lifecycle action to implement the application code.

BCreate a new stack that contains a new layer with the Python code. Route only a small portion of the production traffic to use the new deployment stack. Once the application is validated, slowly increase the production traffic to the new stack using the Canary Deployment. Revert to the old stack, if the new stack deployment fails or does not work.

CCreate a new stack that contains the Python application code. Route all the traffic to the new stack at once so that all the customers get to access the updated application.

DUpdate the existing host instances of the application with the new Python code. This will save the cost of having to maintain two stacks, hence cutting down on the costs.

Question 87 of 100Multiple Choice

Your mobile application includes a photo-sharing service that is expecting tens of thousands of users at launch. You will leverage Amazon Simple Storage Service (S3) for storage of the user Images, and you must decide how to authenticate and authorize your users for access to these images. You also need to manage the storage of these images. Which two of the following approaches should you use? (Choose two)

ACreate an Amazon S3 bucket per user, and use your application to generate the S3 URI for the appropriate content.

BUse AWS Identity and Access Management (IAM) user accounts as your application-level user database, and offload the burden of authentication from your application code.

CAuthenticate your users at the application level, and use AWS Security Token Service (STS) to grant token-based authorization to S3 objects.

DAuthenticate your users at the application level, and send an SMS token message to the user. Create an Amazon S3 bucket with the same name as the SMS message token, and move the user’s objects to that bucket.

EUse a key-based naming scheme comprised from the user IDs for all user objects in a single Amazon S3 bucket.
