4. Download Latest SOA-C02 PDF Dumps for Best Preparation to the cache. B. Deploy an Aurora Replica for the DB cluster. Modify the application to use the reader endpoint for search operations. Use Aurora Auto Scaling to scale the number of replicas based on load. Most Voted C. Use Provisioned IOPS on the storage volumes that support the DB cluster to improve performance sufficiently to support the peak load on the application. D. Increase the instance size in the DB cluster to a size that is sufficient to support the peak load on the application. Use Aurora Auto Scaling to scale the instance size based on load. Answer: A Explanation: Step-by-Step Understand the Problem: The application experiences slower performance during peak activity due to increased load on the Amazon Aurora DB cluster. Performance issues occur primarily during search operations. The goal is to improve performance and maximize resource efficiency. Analyze the Requirements: The solution should improve the performance of the platform. It should maximize resource efficiency, which implies cost-effective and scalable options. Evaluate the Options: Option A: Deploy an Amazon ElastiCache for Redis cluster. ElastiCache for Redis is a managed in-memory caching service that can significantly reduce the load on the database by caching frequently accessed data. By modifying the application to check the cache before querying the database, repeated searches for the same information will be served from the cache, reducing the number of database reads. This is efficient and cost-effective as it reduces database load and improves response times. Option B: Deploy an Aurora Replica and use Auto Scaling. Adding Aurora Replicas can help distribute read traffic and improve performance. Aurora Auto Scaling can adjust the number of replicas based on the load. However, this option may not be as efficient in terms of resource usage compared to caching because it still involves querying the database. Option C: Use Provisioned IOPS. Provisioned IOPS can improve performance by providing fast and consistent I/O. This option focuses on improving the underlying storage performance but doesn't address the inefficiency of handling repeated searches directly. Option D: Increase the instance size and use Auto Scaling. Increasing the instance size can provide more resources to handle peak loads. Aurora Auto Scaling can adjust instance sizes based on the load. This option can be costly and may not be as efficient as caching in handling repeated searches. Select the Best Solution: Option A is the best solution because it leverages caching to reduce the load on the database, which directly addresses the issue of repeated searches causing performance problems. Caching is generally more resource-efficient and cost-effective compared to scaling database instances or storage. Amazon ElastiCache for Redis Documentation Amazon Aurora Documentation 4 / 17

The instance has an attached 1 TB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume. The instance also is EBS-optimized. To save costs, the SysOps administrator stops the instance each evening and restarts the instance each morning. When data processing is active, Amazon CloudWatch metrics on the instance show a consistent 3.000 VolumeReadOps. The SysOps administrator must improve the I/O performance while ensuring data integrity. Which action will meet these requirements? A. Change the instance type to a large, burstable, general purpose instance. B. Change the instance type to an extra large general purpose instance. C. Increase the EBS volume to a 2 TB General Purpose SSD (gp2) volume. D. Move the data that resides on the EBS volume to the instance store. Answer: C Explanation: Step-by-Step Understand the Problem: The EC2 instance processes large data files and uses a 1 TB General Purpose SSD (gp2) EBS volume. CloudWatch metrics show consistent high VolumeReadOps. The requirement is to improve I/O performance while ensuring data integrity. Analyze the Requirements: Improve I/O performance. Maintain data integrity. Evaluate the Options: Option A: Change the instance type to a large, burstable, general-purpose instance. Burstable instances provide a baseline level of CPU performance with the ability to burst to a higher level when needed. However, this does not address the I/O performance directly. Option B: Change the instance type to an extra-large general-purpose instance. A larger instance type might improve performance, but it does not directly address the I/O performance of the EBS volume. Option C: Increase the EBS volume to a 2 TB General Purpose SSD (gp2) volume. Increasing the size of a General Purpose SSD (gp2) volume can increase its IOPS. The larger the volume, the higher the baseline performance in terms of IOPS. Option D: Move the data that resides on the EBS volume to the instance store. Instance store volumes provide high I/O performance but are ephemeral, meaning data will be lost if the instance is stopped or terminated. This does not ensure data integrity. Select the Best Solution: Option C: Increasing the EBS volume size to 2 TB will provide higher IOPS, improving I/O performance while maintaining data integrity. Amazon EBS Volume Types General Purpose SSD (gp2) Volumes Increasing the size of the General Purpose SSD (gp2) volume is an effective way to improve I/O performance while ensuring data integrity remains intact. 9.With the threat of ransomware viruses encrypting and holding company data hostage, which action 7 / 17

Answer: A,C Explanation: To determine the service costs incurred by each developer, follow these steps: Activate the createdBy Tag: Tagging resources with a createdBy tag helps identify which user created the resource. This tag should be applied consistently across all resources created by the developers. Reference: Tagging Your Resources Analyze Usage with Cost Explorer: Use Cost Explorer to filter and group cost and usage data by the createdBy tag. This provides a breakdown of costs incurred by each developer. Reference: Analyzing Your Costs with Cost Explorer These two steps together will provide a detailed analysis of the costs incurred by each developer in the AWS account. 19.A company website contains a web tier and a database tier on AWS. The web tier consists of Amazon EC2 instances that run in an Auto Scaling group across two Availability Zones. The database tier runs on an Amazon ROS for MySQL Multi-AZ DB instance. The database subnet network ACLs are restricted to only the web subnets that need access to the database. The web subnets use the default network ACL with the default rules. The company's operations team has added a third subnet to the Auto Scaling group configuration. After an Auto Scaling event occurs, some users report that they intermittently receive an error message. The error message states that the server cannot connect to the database. The operations team has confirmed 16 / 17

Which combination of actions should a SysOps administrator take so that the web servers can communicate with the DB instance? (Select TWO.) A. On the default ACL. create inbound Allow rules of type TCP with the ephemeral port range and the source as the database subnets. B. On the default ACL, create outbound Allow rules of type MySQL/Aurora (3306). Specify the destinations as the database subnets. C. On the network ACLs for the database subnets, create an inbound Allow rule of type MySQL/Aurora (3306). Specify the source as the third web subnet. D. On the network ACLs for the database subnets, create an outbound Allow rule of type TCP with the ephemeral port range and the destination as the third web subnet. E. On the network ACLs for the database subnets, create an outbound Allow rule of type MySQL/Aurora (3306). Specify the destination as the third web subnet. Answer: C,D Explanation: To ensure that the new web subnet can communicate with the database instance, follow these steps: Create an Inbound Allow Rule for MySQL/Aurora (3306): On the network ACL for the database subnets, add an inbound allow rule to permit traffic from the third web subnet on port 3306 (MySQL/Aurora). Reference: Network ACLs Create an Outbound Allow Rule for Ephemeral Ports: On the network ACL for the database subnets, add an outbound allow rule to permit traffic to the third web subnet on the ephemeral port range (1024-65535). Reference: Ephemeral Ports These changes will ensure that the new subnet can communicate with the database, resolving the connectivity issues. 20.A company is running an application on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances are launched by an Auto Scaling group and are automatically registered in a target group. A SysOps administrator must set up a notification to alert application owners when targets fail health checks. What should the SysOps administrator do to meet these requirements? A. Create an Amazon CloudWatch alarm on the UnHealthyHostCount metric. Configure an action to send an Amazon Simple Notification Service (Amazon SNS) notification when the metric is greater than 0. B. Configure an Amazon EC2 Auto Scaling custom lifecycle action to send an Amazon Simple Notification Service (Amazon SNS) notification when an instance is in the Pending:Wait state. C. Update the Auto Scaling group. Configure an activity notification to send an Amazon Simple Notification Service (Amazon SNS) notification for the Unhealthy event type. D. Update the ALB health check to send an Amazon Simple Notification Service (Amazon SNS) notification when an instance is unhealthy. Answer: A 17 / 17
