It is designed to provide consistent, low-latency performance at large scale without requiring customers to manage database servers. DynamoDB can automatically scale capacity and provides features such as global tables, streams, backups, and encryption. Aurora and RDS are relational database services, while Redshift is designed primarily for analytical workloads. DynamoDB is therefore the appropriate choice when an application requires scalable NoSQL storage with very low latency.<\/span><\/p>\n<h3><b>Question 142<\/b><\/h3>\n<p><b>Which AWS service allows a company to create isolated virtual networks with control over subnets, routing, and network security?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon VPC<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Route 53<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS IAM<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon CloudFront<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon Virtual Private Cloud (VPC) allows organizations to create logically isolated networks within AWS. A VPC provides control over IP address ranges, subnets, route tables, gateways, and network security configurations. Public and private subnets can be designed according to application requirements, while security groups and Network ACLs provide traffic controls. Route 53 provides DNS services, IAM manages identities and permissions, and CloudFront delivers content globally. Amazon VPC is therefore the fundamental service for creating and controlling an isolated network environment in AWS.<\/span><\/p>\n<h3><b>Question 143<\/b><\/h3>\n<p><b>A company needs to send messages to a queue and ensure that a message is not processed by another consumer while the current consumer is working on it. Which SQS feature should be configured?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dead-letter queue<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Long polling<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Visibility timeout<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Message retention period<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon SQS visibility timeout temporarily hides a message from other consumers after a consumer receives it. This gives the current consumer time to process the message before it becomes visible again. If processing succeeds, the consumer can delete the message from the queue. If processing fails or the message is not deleted before the visibility timeout expires, it can become available for another attempt. Dead-letter queues handle repeatedly failed messages, long polling reduces empty responses, and retention controls how long messages remain stored.<\/span><\/p>\n<h3><b>Question 144<\/b><\/h3>\n<p><b>Which AWS service is designed to provide a managed firewall for filtering network traffic across VPCs and protecting applications from sophisticated network threats?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon GuardDuty<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Network Firewall<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS CloudTrail<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Inspector<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">AWS Network Firewall is a managed, stateful network firewall designed to inspect and control traffic entering or leaving Amazon VPC environments. It supports firewall rules for filtering network traffic and can be used in architectures requiring centralized network security controls. GuardDuty focuses on threat detection, CloudTrail records API activity, and Inspector evaluates workloads for vulnerabilities. Network Firewall is therefore appropriate when an organization needs managed network traffic inspection and filtering across VPC-based workloads.<\/span><\/p>\n<h3><b>Question 145<\/b><\/h3>\n<p><b>Which AWS service can automatically register and deregister EC2 instances with a load balancer as instances are added or removed by Auto Scaling?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Elastic Load Balancing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon S3<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS CloudTrail<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Route 53<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Elastic Load Balancing integrates with EC2 Auto Scaling to automatically distribute traffic across instances and maintain an up-to-date set of healthy targets. When Auto Scaling launches new instances, they can be registered with the load balancer, and when instances are terminated, they can be removed from the target group. Health checks help ensure that traffic is directed only to healthy targets. S3 provides object storage, CloudTrail records API activity, and Route 53 provides DNS routing. Elastic Load Balancing is therefore the appropriate service for distributing traffic across dynamically changing compute resources.<\/span><\/p>\n<h3><b>Question 146<\/b><\/h3>\n<p><b>Which AWS service can be used to create a centralized event bus that receives events from AWS services and custom applications?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon SQS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon EventBridge<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon EBS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Backup<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon EventBridge provides event buses that can receive events from AWS services, applications, and supported third-party sources. Rules can evaluate incoming events and route matching events to appropriate targets, enabling loosely coupled event-driven architectures. This allows applications to react to events without creating direct dependencies between every producer and consumer. SQS is primarily a message queue, EBS provides block storage, and AWS Backup manages backups. EventBridge is therefore the appropriate service when a centralized event bus is needed for application and AWS service events.<\/span><\/p>\n<h3><b>Question 147<\/b><\/h3>\n<p><b>A company wants to use a single S3 bucket name across multiple AWS accounts but receives a bucket-name conflict. What should the company understand?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 bucket names must be globally unique within the AWS partition<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 bucket names only need to be unique within an account<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 bucket names only need to be unique within a Region<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 bucket names can be duplicated if encryption is enabled<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon S3 bucket names must be globally unique within the AWS partition because bucket names form part of the bucket&#8217;s globally addressable namespace. Two customers cannot generally create separate general-purpose buckets using the same name within the same AWS partition. This requirement is different from many AWS resources whose names are scoped to an account or Region. Encryption does not change bucket-name uniqueness. Therefore, when creating S3 buckets, organizations should select names that are unique across the applicable AWS partition.<\/span><\/p>\n<h3><b>Question 148<\/b><\/h3>\n<p><b>Which AWS service provides a managed database cache that supports Redis-compatible workloads and can improve application response times?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon RDS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon ElastiCache<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Athena<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Redshift<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon ElastiCache provides managed in-memory caching for applications and supports engines such as Valkey and Memcached. It can store frequently accessed information in memory, reducing repeated queries against backend databases and improving application response times. ElastiCache is commonly used for caching sessions, frequently accessed records, and temporary application data. RDS provides relational databases, Athena queries data in S3, and Redshift provides data warehousing. ElastiCache is therefore the appropriate service when an application needs a managed in-memory caching layer.<\/span><\/p>\n<h3><b>Question 149<\/b><\/h3>\n<p><b>Which AWS storage service provides a shared file system that automatically grows and shrinks as files are added or removed?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon EBS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon S3<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon EFS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">EC2 Instance Store<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon Elastic File System (EFS) provides a managed, elastic file system that can automatically grow and shrink as data is added or removed. Applications can access the file system concurrently from multiple supported compute resources, making EFS useful for shared file-based workloads. Customers do not need to manually provision a fixed amount of storage capacity. EBS provides block storage, S3 provides object storage, and Instance Store provides temporary local storage. EFS is therefore the appropriate choice for an automatically scaling shared file system.<\/span><\/p>\n<h3><b>Question 150<\/b><\/h3>\n<p><b>A company needs to distribute traffic between several EC2 instances and wants the load balancer to terminate HTTPS connections before forwarding requests to the targets. Which service should be used?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Network Load Balancer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Application Load Balancer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">NAT Gateway<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Transit Gateway<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An Application Load Balancer supports HTTP and HTTPS traffic and can terminate TLS connections at the load balancer. This allows the load balancer to handle encryption-related processing before forwarding requests to backend targets according to listener and routing rules. ALB is particularly suitable for web applications that require Layer 7 routing capabilities. Network Load Balancer operates primarily at Layer 4, while NAT Gateway and Transit Gateway serve networking purposes rather than application traffic distribution. Application Load Balancer is therefore the appropriate choice for HTTPS termination and web traffic routing.<\/span><\/p>\n<h3><b>Question 151<\/b><\/h3>\n<p><b>Which AWS service can provide temporary access to an S3 object without changing the object&#8217;s public access permissions?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 presigned URL<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 bucket website hosting<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 public access block<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">S3 Transfer Acceleration<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An S3 presigned URL provides temporary access to a specific S3 object or operation without making the object publicly accessible. The URL is generated using credentials from an authorized AWS identity and includes a limited expiration period. This makes presigned URLs useful for temporary downloads, uploads, and controlled sharing of private objects. S3 website hosting serves website content, Public Access Block prevents certain public access configurations, and Transfer Acceleration improves transfer performance. A presigned URL is therefore the appropriate solution for temporary private object access.<\/span><\/p>\n<h3><b>Question 152<\/b><\/h3>\n<p><b>Which AWS service provides centralized management of workforce access to multiple AWS accounts and applications using single sign-on capabilities?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Cognito<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS IAM Identity Center<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Secrets Manager<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon GuardDuty<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">AWS IAM Identity Center provides centralized workforce access management for AWS accounts and supported applications. It can integrate with identity sources and allows administrators to assign users and groups access to multiple AWS accounts through centrally managed permissions. This simplifies workforce authentication and reduces the need to maintain separate credentials for each account. Cognito is primarily intended for application users, Secrets Manager stores secrets, and GuardDuty detects threats. IAM Identity Center is therefore the appropriate service for centralized workforce single sign-on and account access.<\/span><\/p>\n<h3><b>Question 153<\/b><\/h3>\n<p><b>Which AWS service can automatically detect whether an AWS resource configuration violates an organization&#8217;s compliance requirements?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Config<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon CloudFront<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon SQS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Direct Connect<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">AWS Config can continuously evaluate AWS resource configurations against predefined or custom rules. Organizations can use these rules to determine whether resources comply with security, governance, and operational requirements. For example, a rule could check whether storage resources have encryption enabled or whether specific network configurations are present. Config also maintains configuration history, which helps with auditing and troubleshooting. CloudFront provides content delivery, SQS provides messaging, and Direct Connect provides dedicated connectivity. AWS Config is therefore the appropriate service for configuration compliance evaluation.<\/span><\/p>\n<h3><b>Question 154<\/b><\/h3>\n<p><b>A company needs a highly available application that can continue operating if an entire Availability Zone becomes unavailable. Which design is most appropriate?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Deploy all resources in one Availability Zone<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Deploy resources across multiple Availability Zones<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use a larger EC2 instance in one Availability Zone<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use only an S3 bucket<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Deploying application resources across multiple Availability Zones improves resilience against failures affecting an entire Availability Zone. A load balancer can distribute requests among healthy resources in different zones, while Auto Scaling can help maintain capacity when instances fail. Keeping all resources in one zone creates a single point of failure at the Availability Zone level, and simply using a larger instance does not provide zonal redundancy. S3 may provide highly durable storage but does not by itself create a complete highly available application architecture. Multi-AZ deployment is therefore the appropriate design.<\/span><\/p>\n<h3><b>Question 155<\/b><\/h3>\n<p><b>Which AWS service is designed to improve global application performance by caching content close to end users?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Direct Connect<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon CloudFront<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon RDS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Config<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon CloudFront is a global content delivery network that caches content at edge locations closer to users. By serving cached content from nearby locations, CloudFront can reduce latency and decrease the number of requests reaching the origin. It can deliver static and dynamic content, APIs, and streaming media. Direct Connect provides dedicated connectivity, RDS provides managed relational databases, and Config evaluates resource configurations. CloudFront is therefore the appropriate service when an organization needs to improve global application performance through edge caching and content delivery.<\/span><\/p>\n<h3><b>Question 156<\/b><\/h3>\n<p><b>Which AWS service can provide a durable queue with a dead-letter queue for messages that repeatedly fail processing?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon SNS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon SQS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon EventBridge<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS Step Functions<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Amazon SQS supports dead-letter queues, which can receive messages that fail processing repeatedly after exceeding a configured retry threshold. This prevents problematic messages from continuously blocking normal processing and allows developers to inspect and troubleshoot failed messages separately. SQS provides durable asynchronous messaging and helps decouple application components. SNS focuses on pub\/sub notifications, EventBridge routes events, and Step Functions orchestrates workflows. Amazon SQS is therefore the appropriate service when reliable queue processing and dead-letter handling are required.<\/span><\/p>\n<h3><b>Question 157<\/b><\/h3>\n<p><b>Which AWS service allows an organization to define a private connection between VPCs without using public IP addresses, while requiring the VPCs to be directly connected?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">VPC Peering<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Internet Gateway<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">NAT Gateway<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon CloudFront<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">VPC Peering establishes private network connectivity between two VPCs using private IP addresses. Once configured with appropriate route tables and security controls, resources in the peered VPCs can communicate without routing traffic through the public internet. VPC peering connections are not transitive, meaning a VPC cannot automatically use one peering connection to reach another VPC through a third VPC. Internet and NAT Gateways provide internet-related connectivity, while CloudFront provides content delivery. VPC Peering is therefore suitable for direct private connectivity between two VPCs.<\/span><\/p>\n<h3><b>Question 158<\/b><\/h3>\n<p><b>Which AWS service can automatically encrypt data using AWS-managed or customer-managed cryptographic keys and integrate with many AWS services?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS KMS<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Route 53<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AWS CloudTrail<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon CloudWatch<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">AWS Key Management Service (KMS) provides centralized management of cryptographic keys used to protect data across AWS services and applications. Customers can use AWS-managed keys or create and control customer-managed KMS keys depending on their security and governance requirements. KMS integrates with services such as S3, EBS, RDS, and other AWS resources to support encryption at rest. Route 53 provides DNS, CloudTrail records API activity, and CloudWatch provides monitoring. KMS is therefore the appropriate service for centralized cryptographic key management.<\/span><\/p>\n<h3><b>Question 159<\/b><\/h3>\n<p><b>A company wants to reduce database reads by storing frequently requested results in memory.

Services such as Amazon ElastiCache can implement this architecture and reduce database workload while improving response times. Multi-AZ deployments primarily improve availability, Read Replicas scale database reads but still require database queries, and sharding distributes data across multiple database partitions. A caching pattern is therefore the most direct solution when the objective is to reduce repeated database reads for frequently requested information.<\/span><\/p>\n<h3><b>Question 160<\/b><\/h3>\n<p><b>Which AWS Well-Architected Framework pillar focuses on selecting and using computing resources efficiently to meet changing business requirements?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Security<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reliability<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Performance Efficiency<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cost Optimization<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<p><b>Explanation<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The Performance Efficiency pillar focuses on using computing resources efficiently and adapting resource selection as workload requirements change. It encourages organizations to use managed services, experiment with suitable technologies, monitor performance, and select resources that meet current requirements without unnecessarily limiting future flexibility. Security focuses on protecting systems and data, Reliability focuses on consistent operation and recovery, and Cost Optimization focuses on minimizing unnecessary spending. Performance Efficiency is therefore the appropriate pillar when the primary objective is achieving efficient workload performance while adapting resources to changing requirements.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>View Full\u00a0Amazon AWS Certified Solutions Architect \u2013 Associate SAA-C03 Exam Dumps\u00a0and Practice Test Dumps &nbsp; Question 141 Which AWS service provides a managed key-value and document database that can deliver single-digit millisecond performance at scale?
