AWS Certified Solutions Architect - Professional

Architecting Large-Scale Cloud Infrastructures: Why True Multi-Account System Logic Outforms Static Test Banks

We have coached hundreds of principal cloud engineers, enterprise systems integrators, and technical solutions architects through this high-cognitive professional-tier Amazon Web Services milestone. Let's look honestly at the modern enterprise cloud transformation training landscape. The software and infrastructure specialists who struggle on this intensive, 180-minute multi-domain evaluation are almost always those who leaned heavily on low-quality, linear test materials—those flat, context-stripped answer repositories floating around unverified technology forums. Those static, unverified materials simply cannot prepare you for live distributed infrastructure configurations or the intricate cross-account permission structures tested on the real exam. Candidates frequently spend months looking for high-yield aws sap-c02 exam questions online, trying to locate realistic aws certified solutions architect professional to measure their analytical capability, or hunting for an updated AWS Certified Professional that breaks down multi-region data replication pipelines. They quickly discover that rote memorization fails completely when faced with complex, scenario-based hybrid routing configurations and sudden recovery time objective failures.

 

At Exact2Pass, our framework targets the underlying structural logic, the AWS Well-Architected Framework pillars, and lifecycle governance of the active cloud native ecosystem instead. Our premium preparation platform delivers comprehensive functional breakdowns for every enterprise landing zone deployment and automated migration scenario. You will master actual production-grade core engineering patterns instead of leaning on short-sighted memorization shortcuts. We map out AWS Control Tower organization structures, Service Control Policy (SCP) guardrail boundaries, AWS Transit Gateway hub-and-spoke multi-account networking, and continuous continuous integration delivery pipelines step by step. Our learning material is designed from the ground up by active, certified principal architects who design and maintain multi-million dollar cloud environments daily. Because of that, we completely avoid mindless, repetitive question repositories. Instead, our software acts as an active deployment simulation that forces you to evaluate infrastructure cost metrics, track storage lifecycle transitions, and configure identity federation pathways like a veteran enterprise consultant. You will learn the exact reason why a specific global application routing policy or database failover blueprint succeeds or flags performance violations under high traffic loads. That is how you build real confidence before checking into your official account dashboard to launch your secure Pearson VUE proctored exam workspace. Our adaptive simulation tools develop deep, practical environment skills that transfer perfectly to production enterprise tenants, helping you pass on your very first try.

Question # 136

A company is running applications on AWS in a multi-account environment. The company ' s sales team and marketing team use separate AWS accounts in AWS Organizations.

The sales team stores petabytes of data in an Amazon S3 bucket. The marketing team uses Amazon QuickSight for data visualizations. The marketing team needs access to data that the sates team stores in the S3 bucket. The company has encrypted the S3 bucket with an AWS Key Management Service (AWS KMS) key. The marketing team has already created the IAM service role for QuickSight to provide QuickSight access in the marketing AWS account. The company needs a solution that will provide secure access to the data in the S3 bucket across AWS accounts.

Which solution will meet these requirements with the LEAST operational overhead?

A.

Create a new S3 bucket in the marketing account. Create an S3 replication rule in the sales account to copy the objects to the new S3 bucket in the marketing account. Update the QuickSight permissions in the marketing account to grant access to the new S3 bucket.

B.

Create an SCP to grant access to the S3 bucket to the marketing account. Use AWS Resource Access Manager (AWS RAM) to share the KMS key from the sates account with the marketing account. Update the QuickSight permissions in the marketing account to grant access to the S3 bucket.

C.

Update the S3 bucket policy in the marketing account to grant access to the QuickSight role. Create a KMS grant for the encryption key that is used in the S3 bucket. Grant decrypt access to the QuickSight role. Update the QuickSight permissions in the marketing account to grant access to the S3 bucket.

D.

Create an IAM role in the sales account and grant access to the S3 bucket. From the marketing account, assume the IAM role in the sales account to access the S3 bucket. Update the QuickSight rote, to create a trust relationship with the new IAM role in the sales account.

Question # 137

A digital marketing company has multiple AWS accounts that belong to various teams. The creative team uses an Amazon S3 bucket in its AWS account to securely store images and media files that are used as content for the company ' s marketing campaigns. The creative team wants to share the S3 bucket with the strategy team so that the strategy team can view the objects.

A solutions architect has created an IAM role that is named strategy_reviewer in the Strategy account. The solutions architect also has set up a custom AWS Key Management Service (AWS KMS) key in the Creative account and has associated the key with the S3 bucket. However, when users from the Strategy account assume the IAM role and try to access objects in the S3 bucket, they receive an Account.

The solutions architect must ensure that users in the Strategy account can access the S3 bucket. The solution must provide these users with only the minimum permissions that they need.

Which combination of steps should the solutions architect take to meet these requirements? (Select THREE.)

A.

Create a bucket policy that includes read permissions for the S3 bucket. Set the principal ofthe bucket policy to the account ID of the Strategy account

Question # 139

A company needs to optimize the infrastructure for an application that uploads data to Amazon S3. The uploads average 64 KB in size. When the data is uploaded, Amazon S3 sends an event to Amazon EventBridge. EventBridge then invokes an Amazon ECS application task.

The ECS task processes the data and stores the results in an Amazon DynamoDB table. Processing takes an average of 15 minutes. The company must keep the S3 data for 5 years and must keep the DynamoDB data for 15 days.

Question # 145

A company has a website that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The ALB is associated with an AWS WAF web ACL.

The website often encounters attacks in the application layer. The attacks produce sudden and significant increases in traffic on the application server. The access logs show that each attack originates from different IP addresses. A solutions architect needs to implement a solution to mitigate these attacks.

Question # 146

A solutions architect needs to review the design of an Amazon EMR cluster that is using the EMR File System (EMRFS). The cluster performs tasks that are critical to business needs. The cluster is running Amazon EC2 On-Demand Instances at all times tor all task, primary, and core nodes. The EMR tasks run each morning, starting at 1 ;00 AM. and take 6 hours to finish running. The amount of time to complete the processing is not a priority because the data is not referenced until late in the day.

Enable Amazon CloudFront and configure the origin to reference an Elastic Load Balancer in front of the fleet of EC2 instances.

Question # 149

A company has implemented a new security requirement According to the new requirement, the company must scan all traffic from corporate AWS instances in the company ' s VPC for violations of the company ' s security policies. As a result of these scans the company can block access to and from specific IP addresses.

To meet the new requirement, the company deploys a set of Amazon EC2 instances in private subnets to serve as transparent proxies The company installs approved proxy server software on these EC2 instances The company modifies the route tables on all subnets to use the corresponding EC2 instances with proxy software as the default route The company also creates security groupsthat are compliant with the security policies and assigns these security groups to the EC2 instances
