Answer: C Explanation: Amazon S3 sends event notifications about S3 buckets (for example, object created, object removed, or object restored) to an SNS topic in the same Region. The SNS topic publishes the event to an SQS queue in the central Region. The SQS queue is configured as the event source for your Lambda function and buffers the 9 Amazon Web Services SAA-C03 : Practice Test event messages for the Lambda function. The Lambda function polls the SQS queue for messages and processes the Amazon S3 event notifications according to your application’s requirements. https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/subscribe-a-lambda- function-to-event-notifications-from-s3-buckets-in-different-aws-regions.html Question No : 14 A company runs its ecommerce application on AWS. Every new order is published as a message in a RabbitMQ queue that runs on an Amazon EC2 instance in a single Availability Zone. These messages are processed by a different application that runs on a separate EC2 instance. This application stores the details in a PostgreSQL database on another EC2 instance. All the EC2 instances are in the same Availability Zone. The company needs to redesign its architecture to provide the highest availability with the least operational overhead. What should a solutions architect do to meet these requirements? A. Migrate the queue to a redundant pair (active/standby) of RabbitMQ instances on Amazon MQ.

The media files must be resilient to the loss of an Availability Zone Some files are accessed frequently while other files are rarely accessed in an 11 Amazon Web Services SAA-C03 : Practice Test unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files. Which storage option meets these requirements? A. S3 Standard B. S3 Intelligent-Tiering C. S3 Standard-Infrequent Access {S3 Standard-IA) D. S3 One Zone-Infrequent Access (S3 One Zone-IA) Answer: B Explanation: S3 Intelligent-Tiering - Perfect use case when you don't know the frequency of access or irregular patterns of usage. Amazon S3 offers a range of storage classes designed for different use cases. These include S3 Standard for general-purpose storage of frequently accessed data; S3 Intelligent-Tiering for data with unknown or changing access patterns; S3 Standard- Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone- IA) for long-lived, but less frequently accessed data; and Amazon S3 Glacier (S3 Glacier) and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation. If you have data residency requirements that can’t be met by an existing AWS Region, you can use the S3 Outposts storage class to store your S3 data on- premises. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application.

Configure Amazon DynamoDB Streams to invoke an AWS Lambda function when a new item is created in the table Configure the Lambda function to delete items in the table that are older than 30 days D. Extend the application to add an attribute that has a value of the current timestamp plus 30 days to each new item that is created in the (able Configure DynamoDB to use the attribute as (he TTL attribute Answer: D Explanation: Amazon DynamoDB Time to Live (TTL) allows you to define a per-item timestamp to determine when an item is no longer needed. Shortly after the date and time of the specified timestamp, DynamoDB deletes the item from your table without consuming any write throughput. TTL is provided at no extra cost as a means to reduce stored data volumes by retaining only the items that remain current for your workload’s needs. TTL is useful if you store items that lose relevance after a specific time. The following are example TTL use cases: Remove user or sensor data after one year of inactivity in an application. Archive expired items to an Amazon S3 data lake via Amazon DynamoDB Streams and AWS Lambda. Retain sensitive data for a certain amount of time according to contractual or regulatory obligations. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html Question No : 24 A company recently migrated to AWS and wants to implement a solution to protect the traffic that flows in and out of the production VPC.

Configure an Application Loa d Balancer with an AWS Lambda target that uses the Express js framework. Answer: B Explanation: In Static Websites, Web pages are returned by the server which are prebuilt. They use simple languages such as HTML, CSS, or JavaScript. There is no processing of content on the server (according to the user) in Static Websites. Web pages are returned by the server with no change therefore, static Websites are fast. There is no interaction with databases. Also, they are less costly as the host does not need to support server-side processing with different languages. ============ In Dynamic Websites, Web pages are returned by the server which are processed during runtime means they are not prebuilt web pages but they are built during runtime according to the user’s demand. These use server-side scripting languages such as PHP, Node.js, ASP.NET and many more supported by the server. So, they are slower than static websites but updates and interaction with databases are possible. Question No : 43 A company is building an ecommerce web application on AWS.

(Select TWO ) A. Configure the security group for the web tier to allow inbound traffic on port 443 from 0.0.0.0/0. B. Configure the security group for the web tier to allow outbound traffic on port 443 from 0.0.0.0/0. C. Configure the security group for the database tier to allow inbound traffic on port 1433 from the security group for the web tier. D. Configure the security group for the database tier to allow outbound traffic on ports 443 and 1433 to the security group for the web tier. E. Configure the security group for the database tier to allow inbound traffic on ports 443 and 1433 from the security group for the web tier. Answer: A,C Explanation: "Security groups create an outbound rule for every inbound rule." Not completely right. Statefull does NOT mean that if you create an inbound (or outbound) rule, it will create an outbound (or inbound) rule. What it does mean is: suppose you create an inbound rule on port 443 for the X ip. When a request enters on port 443 from X ip, it will allow traffic out for that request in the port 443. However, if you look at the outbound rules, there will not be any outbound rule on port 443 unless explicitly create it. In ACLs, which are stateless, you would have to create an inbound rule to allow incoming requests and an outbound rule to allow your application responds to those incoming requests. https://docs.aws.amazon.com/vpc/latest/userguide/VPC_SecurityGroups.html#SecurityGro 46 Amazon Web Services SAA-C03 : Practice Test upRules Question No : 74 A solutions architect needs to securely store a database user name and password that an application uses to access an Amazon RDS DB instance.

Container-based applications: ECS "Amazon ECS enables you to launch and stop your container-based applications by using simple API calls. You can also retrieve the state of your cluster from a centralized service and have access to many familiar Amazon EC2 features." 3. Little manual intervention: Fargate You can run your tasks and services on a serverless infrastructure that is managed by AWS Fargate. Alternatively, for more control over your infrastructure, you can run your tasks and services on a cluster of Amazon EC2 instances that you manage. Question No : 77 A medical records company is hosting an application on Amazon EC2 instances. The application processes customer data files that are stored on Amazon S3. The EC2 instances are hosted in public subnets. The EC2 instances access Amazon S3 over the internet, but they do not require any other network access. A new requirement mandates that the network traffic for file transfers take a private route and not be sent over the internet. 49 Amazon Web Services SAA-C03 : Practice Test Which change to the network architecture should a solutions architect recommend to meet this requirement? A. Create a NAT gateway. Configure the route table for the public subnets to send traffic to Amazon S3 through the NAT gateway. B.
