Categories AWS CertificationAWS Solution Architect Associate Post author By Bishwa Post date January 4, 2022 No Comments on AWS Solution Architect Associate 5 Created on January 04, 2022AWS Solution Architect Associate 1 / 10An ELB is diverting traffic across 5 instances. One of the instances was unhealthy only for 20 minutes. What will happen after 20 minutes when the instance becomes healthy? ELB will never divert traffic back to the same instance The ELB stops sending traffic to the instance that failed its health check ELB terminates the instance once it is unhealthy. Thus, the instance can not be healthy after 10 minutes. ELB will not automatically send traffic to the same instance. However, the user can configure to start sending traffic to the same instance. 2 / 10Currently an FTP server is used to ingest data from a customer of varying sizes; some files as large as 1 GB and as small as 5 KB. A more robust, scalable, and cost-effective solution would be preferred. Processing of the data must happen with an hour or less of the data arriving. Of the following options, which design best suits the replacement of the FTP server design? The clients are open to installing other clients/agents, if needed. Build an autoscaling fleet of EC2 instances, spread across AZs for resiliency, and fronted with a Network Load Balancer to using an EIP for each AZ. Build a CRON job that looks for new files every 10 minutes and copies the files to a processing engine. Create an S3 bucket; establish an S3 event that triggers a Lambda function to process each object upon upload. Have the customer utilize either the AWS CLI or other S3 client to send data to S3. Create a Kinesis data stream to receive the data and write some Kinesis consumer applications to extract the uploads. The data would be placed into the stream through the Kinesis agent Create a small producer application which will send files SQS for the customer to leverage, and another consumer application which checks the queue for the uploaded files. 3 / 10A user is configuring the HTTPS protocol on a front end ELB and the SSL protocol for the back-end listener in ELB. What will ELB do? Receives requests on HTTPS and sends it to the back end instance on SSL It will allow you to create the configuration but ELB will not work as expected It will not allow you to create this configuration It will allow you to create the configuration, but the instance will not pass the health check 4 / 10Your tech lead wants you to configure AutoScaling which scales up when the CPU utilization is above 70% and scales down when the CPU utilization is below 30%. How can you configure AutoScaling for the above mentioned conditions? Configure ELB to notify AutoScaling on load increase or decreas Use AutoScaling by manually modifying the desired capacity during a condition Use dynamic AutoScaling with a policy Use AutoScaling with a schedule 5 / 10A user has launched one EC2 instance in the US West region. The user wants to access the RDS instance launched in the US East region from that EC2 instance. How can the user configure the access for that EC2 instance? Open the security group of the US West region in the RDS security group's ingress rule Configure the IP range of the US West region instance as the ingress security rule of RDS It is not possible to access RDS of the US East region from the US West region Create an IAM role which has access to RDS and laugh an instance in the US West region with it 6 / 10Can one instance be registered with two ELBs in the same region? Yes, provided both ELBs have the same health check configuration Yes, provided both ELBs are in the same AZ No Yes, always 7 / 10With regard to DynamoDB, increases in throughput level of a table will typically---------- Take 24 hours Take around a few seconds Take anywhere from a few minutes to a few hours Be immediate 8 / 10A cloudformation template successfully runs in the region in which it was developed. Upon running the cloudformation template in another region, it creates some resources then fails when it builds EC2 instances. What could be the problem? clouformation templates are unique to the region; a new template must be created for the other region. IDs are unique to the region, and the template likely calls AMI ID's Security Group ID's or others statistically. Replace static ID's with Parameters, Mappings, and Conditions where appropriate. IAM Permissions are preventing template execution A role is not defined in the template for the EC2 instance; a role must be defined 9 / 10Which services could be used to stream custom application logs? AWS cloudTrail AWS CloudWatch logs AWS kinesis data streams aws kinesis firehose 10 / 10What is the development practice used when a failure of the other end occurs, and instead of an endless loop, we stop trying and create a "ping" until the service is back up to resume operations?

Every API of Node js are asynchronous. Node being a single thread, and uses async function calls to maintain the concurrency. Node thread keeps an event loop and whenever any task get completed, it fires the corresponding event which signals the event listener function to get executed.
