A company's application on EC2 instances relies on a Single-AZ RDS for MySQL DB instance. The SysOps administrator needs to ensure failover to minimize downtime.
A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company's AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database. What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?
A company needs to monitor the disk utilization of Amazon Elastic Block Store (Amazon EBS) volumes The EBS volumes are attached to Amazon EC2 Linux Instances A SysOps administrator must set up an Amazon CloudWatch alarm that provides an alert when disk utilization increases to more than 80%. Which combination of steps must the SysOps administrator lake lo meet these requirements? (Select THREE.)
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack. Which solution will meet these requirements?
A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations. Which approach should the SysOps administrator use to optimize this workload?
The SysOps administrator must dynamically reference the latest AMI ID from Systems Manager Parameter Store in CloudFormation templates for new AMI versions.
A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status. All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications. Which solution will meet these requirements?
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?
The SysOps administrator must modify the AWS Config rule that deletes noncompliant SSH inbound rules to update the rule to allow SSH from specific trusted IP addresses instead.
A company is running a serverless application on AWS Lambda. The application stores data in an Amazon RDS for MySQL DB instance. Usage has steadily increased, and recently there have been numerous "too many connections" errors when the Lambda function attempts to connect to the database. The company already has configured the database to use the maximum max_connections value that is possible. What should a SysOps administrator do to resolve these errors?

A SysOps administrator is managing a Memcached cluster in Amazon ElastiCache. The cluster has been heavily used recently, and the administrator wants to use a larger instance type with more memory.

What should the administrator use to make this change?

A.
Use the ModifycacheCluster API and specify a new cacheNodeType.
Answers
A.
Use the ModifycacheCluster API and specify a new cacheNodeType.
B.
Use the createcacheciuster API and specify a new cacheNodeType.
Answers
B.
Use the createcacheciuster API and specify a new cacheNodeType.
C.
Use the Modi fyCacheParameterGcoup API and specify a new CacheNodeType.
Answers
C.
Use the Modi fyCacheParameterGcoup API and specify a new CacheNodeType.
D.
Use the Rebootcacheclustcr API and specify a new CacheNodeType.
Answers
D.
Use the Rebootcacheclustcr API and specify a new CacheNodeType.
Suggested answer: A

Explanation:

To upgrade the instance type of a Memcached cluster in Amazon ElastiCache due to increased usage and the need for more memory:

ModifyCacheCluster API: Utilize the ModifyCacheCluster API call. This API allows you to change various settings of an existing cache cluster, including the instance type, which is referred to as cacheNodeType.

Instance Upgrade: Specify a new, larger cacheNodeType that provides more memory. This upgrade will involve a brief interruption as nodes are replaced with the larger type, but it is necessary to accommodate the increased load and memory requirements.

Cluster Availability: Ensure that the Memcached cluster is configured for minimal downtime during this change. The upgrade process is handled by ElastiCache, and the new nodes will join the cluster with more memory capacity.

This approach enables you to effectively scale up the resources available to your Memcached cluster, enhancing its performance and capacity to handle larger workloads.
