Exam 10: AWS Certified Solutions Architect - Professional (SAP-C01)

In Amazon CloudWatch, you can publish your own metrics with the put-metric-data command. When you create a new metric using the put-metric-data command, it can take up to two minutes before you can retrieve statistics on the new metric using the get-metric-statistics command. How long does it take before the new metric appears in the list of metrics retrieved using the list- metrics command?

A company is developing a gene reporting device that will collect genomic information to assist researchers will collecting large samples of data from a diverse population. The device will push 8 KB of genomic data every second to a data platform that will need to process and analyze the data and provide information back to researchers. The data platform must meet the following requirements: Provide near-real-time analytics of the inbound genomic data Ensure the data is flexible, parallel, and durable Deliver results of processing to a data warehouse Which strategy should a solutions architect use to meet these requirements?

While debugging a backend application for an IoT system that supports globally distributed devices, a Solutions Architect notices that stale data is occasionally being sent to user devices. Devices often share data, and stale data does not cause issues in most cases. However, device operations are disrupted when a device reads the stale data after an update. The global system has multiple identical application stacks deployed in different AWS Regions. If a user device travels out of its home geographic region, it will always connect to the geographically closest AWS Region to write or read data. The same data is available in all supported AWS Regions using an Amazon DynamoDB global table. What change should be made to avoid causing disruptions in device operations?

While implementing the policy keys in AWS Direct Connect, if you use and the request comes from an Amazon EC2 instance, the instance's public IP address is evaluated to determine if access is allowed.

You are designing an SSL/TLS solution that requires HTTPS clients to be authenticated by the Web server using client certificate authentication. The solution must be resilient. Which of the following options would you consider for configuring the web server infrastructure? (Choose 2)

You want to use Amazon Redshift and you are planning to deploy dw1.8xlarge nodes. What is the minimum amount of nodes that you need to deploy with this kind of configuration?

A solutions architect is designing a disaster recovery strategy for a three-tier application. The application has an RTO of 30 minutes and an RPO of 5 minutes for the data tier. The application and web tiers are stateless and leverage a fleet of Amazon EC2 instances. The data tier consists of a 50 TB Amazon Aurora database. Which combination of steps satisfies the RTO and RPO requirements while optimizing costs? (Choose two.)

You want to define permissions for a role in an IAM policy. Which of the following configuration formats should you use?

An organization is planning to extend their data center by connecting their DC with the AWS VPC using the VPN gateway. The organization is setting up a dynamically routed VPN connection. Which of the below mentioned answers is not required to setup this configuration?

A hybrid network architecture must be used during a company's multi-year data center migration from multiple private data centers to AWS. The current data centers are linked together with private fiber. Due to unique legacy applications, NAT cannot be used. During the migration period, many applications will need access to other applications in both the data centers and AWS. Which option offers a hybrid network architecture that is secure and highly available, that allows for high bandwidth and a multi-region deployment post-migration?

A 3-Ber e-commerce web application is currently deployed on-premises, and will be migrated to AWS for greater scalability and elasticity. The web tier currently shares read-only data using a network distributed file system. The app server tier uses a clustering mechanism for discovery and shared session state that depends on IP multicast. The database tier uses shared-storage clustering to provide database failover capability, and uses several read slaves for scaling. Data on all servers and the distributed file system directory is backed up weekly to off-site tapes. Which AWS storage and database architecture meets the requirements of the application?

A Development team is deploying new APIs as serverless applications within a company. The team is currently using the AWS Management Console to provision Amazon API Gateway, AWS Lambda, and Amazon DynamoDB resources. A Solutions Architect has been tasked with automating the future deployments of these serverless APIs. How can this be accomplished?

A company is using AWS Organizations to manage multiple AWS accounts. For security purposes, the company requires the creation of an Amazon Simple Notification Service (Amazon SNS) topic that enables integration with a third-party alerting system in all the Organizations member accounts. A solutions architect used an AWS CloudFormation template to create the SNS topic and stack sets to automate the deployment of CloudFormation stacks. Trusted access has been enabled in Organizations. What should the solutions architect do to deploy the CloudFormation StackSets in all AWS accounts?

In the context of AWS IAM, identify a true statement about user passwords (login profiles).

In Amazon RDS for PostgreSQL, you can provision up to 3TB storage and 30,000 IOPS per database instance. For a workload with 50% writes and 50% reads running on a cr1.8xlarge instance, you can realize over 25,000 IOPS for PostgreSQL. However, by provisioning more than this limit, you may be able to achieve:

Which of the following cache engines does Amazon ElastiCache support?

By default, temporary security credentials for an IAM user are valid for a maximum of 12 hours, but you can request a duration as long as _________ hours.

What feature of the load balancing service attempts to force subsequent connections to a service to be redirected to the same node as long as it is online?

A North American company with headquarters on the East Coast is deploying a new web application running on Amazon EC2 in the us-east-1 Region. The application should dynamically scale to meet user demand and maintain resiliency. Additionally, the application must have disaster recover capabilities in an active-passive configuration with the us-west-1 Region. Which steps should a solutions architect take after creating a VPC in the us-east-1 Region?

A company is running multiple workloads in the AWS Cloud. The company has separate units for software development. The company uses AWS Organizations and federation with SAML to give permissions to developers to manage resources in their AWS accounts. The development units each deploy their production workloads into a common production account. Recently, an incident occurred in the production account in which members of a development unit terminated an EC2 instance that belonged to a different development unit. A solutions architect must create a solution that prevents a similar incident from happening in the future. The solution also must allow developers the possibility to manage the instances used for their workloads. Which strategy will meet these requirements?
