Bug that resulted in a several-minute outage. A solutions architect's deployment methodology must be adjusted to accommodate a canary
Release.
Which solution will satisfy these criteria?
A、
Create an alias for every new deployed version of the Lambda function. Use the AWS CLI update-alias command with the routing-config
Parameter to distribute the load.
B、
Deploy the application into a new CloudFormation stack. Use an Amazon Route 53 weighted routing policy to distribute the load.
C、
Create a version for every new deployed Lambda function. Use the AWS CLI update-function-configuration command with the routing-config
Parameter to distribute the load.

A business wishes to host both a Wordpress blog and a Joomla content management system on a same VPC server. The business want to use
Route 53 to generate distinct domains for each application. Each of these two programs may have around 10 instances inside the business.
During the instance's launch, the organization specified two distinct network interfaces (main + secondary ENIs) with their unique Elastic IPs. The
Advice was to utilize a public IP from AWS rather than an elastic IP, since the account's elastic IP allotment is limited per region.
Which course of action would you suggest to the organization?
A、
Only Elastic IP can be used by requesting limit increase, since AWS does not assign a public IP to an instance with multiple ENIs.
B、
AWS VPC does not attach a public IP to an ENI; so the only way is to use an Elastic IP.
C、
I agree with the suggestion but will prefer that the organization should use separate subnets with each ENI for different public IPs.
D、
I agree with the suggestion and it is recommended to use a public IP from AWS since the organization is going to use DNS with Route 53.

A big real estate firm is considering the cost-effective addition of a location-based alert to their current mobile application. Currently, the
Application's backend architecture is hosted on AWS. Users who subscribe up to this service will get smartphone notifications about real-estate
Otters in their vicinity. To be relevant, warnings must be sent within a few minutes. The present mobile application is used by 5 million people in
The United States.
Which of the following architectural recommendations would you offer to a client?
A、
The mobile application will submit its location to a web service endpoint utilizing Elastic Load Balancing and EC2 instances; DynamoDB will
Be used to store and retrieve relevant offers EC2 instances will communicate with mobile earners/device providers to push alerts back to
Mobile application.
B、
Use AWS DirectConnect or VPN to establish connectivity with mobile carriers EC2 instances will receive the mobile applications location
Through carrier connection: RDS will be used to store and relevant offers. EC2 instances will communicate with mobile carriers to push alerts
Back to the mobile application.
C、
The mobile application will send device location using SQS. EC2 instances will retrieve the relevant others from DynamoDB. AWS Mobile
Push will be used to send offers to the mobile application.
D、
The mobile application will send device location using AWS Mobile Push EC2 instances will retrieve the relevant offers from DynamoDB.
EC2 instances will communicate with mobile carriers/device providers to push alerts back to the mobile application.

Amazon EC2 instances are used by a business to execute applications. The organization intends to use an Auto Scaling group to manage the
Instances. A solutions architect must ensure that Amazon CloudWatch Logs gathers logs from all new instances as part of this transition. The
New Auto Scaling group will begin with an Amazon Linux 2 AMI and no key pair.
Which solution satisfies these criteria?
A、
Create an Amazon CloudWatch agent configuration for the workload. Store the CloudWatch agent configuration in an Amazon S3 bucket.
Write an EC2 user data script to fetch the configuration file from Amazon S3. Configure the CloudWatch agent on the instance during initial
Boot.
B、
Create an Amazon CloudWatch agent configuration for the workload in AWS Systems Manager Parameter Store. Create a Systems Manager
Document that installs and configures the CloudWatch agent by using the configuration. Create an Amazon EventBridge (Amazon CloudWatch
Events) rule on the default event bus with a Systems Manager Run Command target that runs the document whenever an instance enters the
Running state.
C、
Create an Amazon CloudWatch agent configuration for the workload. Create an AWS Lambda function to install and configure the
CloudWatch agent by using AWS Systems Manager Session Manager. Include the agent configuration inside the Lambda package. Create an
AWS Config custom rule to identify changes to the EC2 instances and invoke Lambda function.
D、
Create an Amazon CloudWatch agent configuration for the workload. Save the CloudWatch agent configuration as part of an AWS Lambda
Deployment package. Use AWS CloudTrail to capture EC2 tagging events and initiate agent installation. Use AWS CodeBuild to configure the
CloudWatch agent on the instances that run the workload.

Your firm is looking to develop an order fulfillment process for selling a customized device that takes an average of three to four days to build with
Some orders lasting up to six months. On your first day, you anticipate receiving ten orders per day. After six months, 1,000 orders per day are
Possible, and 10,000 orders per day after twelve months.
Orders are verified for consistency before being transferred to your manufacturing facility for production quality control, packing, and payment
Processing. Employees may compel the process to repeat a step if the product does not satisfy quality requirements at any level of the process.
Customers are advised through email of the progress of their purchases and any important concerns, such as payment failure.
Your website is hosted on AWS Elastic Beanstalk, and customer data and orders are stored on an RDS MySQL instance.
How can you execute the order fulfillment procedure while maintaining the reliability of email delivery?
A、
Add a business process management application to your Elastic Beanstalk app servers and re-use the ROS database for tracking order
Status use one of the Elastic Beanstalk instances to send emails to customers.
B、
Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 Use the
Decider instance to send emails to customers.
C、
Use SWF with an Auto Scaling group of activity workers and a decider instance in another Auto Scaling group with min/max=1 use SES to
Send emails to customers.
D、
Use an SQS queue to manage all process tasks Use an Auto Scaling group of EC2 Instances that poll the tasks and execute them. Use SES
To send emails to customers.
