An application is running on Amazon EC2 instances behind a Classic Load Balancer.The instances run in an Auto Scaling group across multiple AvailabilityZones.Occasionally multiple incoming requests will receive a 5xx HTTP response when making a request to the Classic Load Balancer.From the AmazonCloudWatch metrics, a SysOps Administrator observes the Elastic Load Balancing (ELB) SpillOverCount metric to be greater than zero during these occasions.These errors can be avoided by triggering scaling actions on which ELB metric?Read More →

A SysOps Administrator noticed that a large number of Elastic IP addresses are being created on the company’s AWS account., but they are not being associated with Amazon EC2 instances, and are incurring Elastic IP address charges in the monthly bill.How can the Administrator identify who is creating the Elastic IP address?Read More →

A new application is being tested for deployment on an Amazon EC2 instance that requires greater IOPS than currently provided by the single 4TB GeneralPurpose SSD (gp2) volume.Which actions should be taken to provide additional Amazon EBS IOPS for the application? (Choose two.)Read More →

A SysOps Administrator has an AWS Direct Connect connection in place in region us-east-1, between an AWS account and a data center.The Administrator is now required to connect the data center to a VPC in another AWS Region, us-west-2, which must have consistent network performance and low-latency.What is the MOST efficient and quickest way to establish this connectivity?Read More →

The InfoSec team has asked the SysOps Administrator to perform some hardening on the company Amazon RDS database instances.Based on this requirement, what actions should be recommended for the start of the security review? (Choose two.)Read More →

An AWS CloudFormation template creates an Amazon RDS instance.This template is used to build up development environments as needed and then delete the stack when the environment is no longer required.The RDS-persisted data must be retained for further use, even after the CloudFormation stack is deleted.How can this be achieved in a reliable and efficient way?Read More →

A SysOps Administrator needs to report on Amazon EC2 instance cost by both project and environment (production, staging, development).Which action would impact the operations team the LEAST?Read More →

A SysOps Administrator receives reports of an Auto Scaling group failing to scale when the nodes running Amazon Linux in the cluster are constrained by high memory utilization.What should the Administrator do to enable scaling to better adapt to the high memory utilization?Read More →

A Content Processing team has notified a SysOps Administrator that their content is sometimes taking a long time to process, whereas other times it processes quickly.The Content Processing submits messages to an Amazon Simple Queue Service (Amazon SQS) queue, which details the files that need to be processed.An Amazon EC2 instance polls the queue to determine which file to process next.How could the Administrator maintain a fast but cost-effective processing time?Read More →

A Development team has an application stack consisting of many OS dependencies and language runtime dependencies.When deploying the application to production, the most important factor is how quickly the instance is operational.What deployment methodology should be used to update the running environments to meet the requirement?Read More →
