NEW QUESTION # 511
A company is creating a prototype of an ecommerce website on AWS. The website consists of an Application Load Balancer, an Auto Scaling group of Amazon EC2 instances for web servers, and an Amazon RDS for MySQL DB instance that runs with the Single-AZ configuration.
The website is slow to respond during searches of the product catalog. The product catalog is a group of tables in the MySQL database that the company does not ate frequently. A solutions architect has determined that the CPU utilization on the DB instance is high when product catalog searches occur.
What should the solutions architect recommend to improve the performance of the website during searches of the product catalog?

  • A. Migrate the product catalog to an Amazon Redshift database. Use the COPY command to load the product catalog tables.
  • B. Implement an Amazon ElastiCache for Redis cluster to cache the product catalog. Use lazy loading to populate the cache.
  • C. Turn on the Multi-AZ configuration for the DB instance. Configure the EC2 instances to throttle the product catalog queries that are sent to the database.
  • D. Add an additional scaling policy to the Auto Scaling group to launch additional EC2 instances when database response is slow.

Answer: B

Explanation:
* Requirement Analysis: The product catalog search is causing high CPU utilization on the MySQL DB instance, slowing down the website.
* ElastiCache Overview: Amazon ElastiCache for Redis can be used to cache frequently accessed data, reducing load on the database.
* Lazy Loading: This caching strategy loads data into the cache only when it is requested, improving response times for repeated queries.
* Implementation:
* Set up an ElastiCache for Redis cluster.
* Modify the application to check the cache before querying the database.
* Use lazy loading to populate the cache on cache misses.
* Conclusion: This approach reduces database load and improves website performance during product catalog searches.

NEW QUESTION # 512
A company uses AWS Organizations with all features enabled and runs multiple Amazon EC2 workloads in the ap-southeast-2 Region. The company has a service control policy (SCP) that prevents any resources from being created in any other Region. A security policy requires the company to encrypt all data at rest.
An audit discovers that employees have created Amazon Elastic Block Store (Amazon EBS) volumes for EC2 instances without encrypting the volumes. The company wants any new EC2 instances that any 1AM user or root user launches in ap-southeast-2 to use encrypted EBS volumes. The company wants a solution that will have minimal effect on employees who create EBS volumes.
Which combination of steps will meet these requirements? (Select TWO.)

  • A. Update the 1AM policies for each account to deny the ec2:CreateVolume action when the ec2:
    Encrypted condition equals false.
  • B. In the Organizations management account, specify the Default EBS volume encryption setting.
  • C. Create an 1AM permission boundary. Attach the permission boundary to the root organizational unit (OU). Define the boundary to deny the ec2:CreateVolume action when the ec2:Encrypted condition equals false.
  • D. In the Amazon EC2 console, select the EBS encryption account attribute and define a default encryption key.
  • E. Create an SCR Attach the SCP to the root organizational unit (OU). Define the SCP to deny the ec2:
    CreateVolume action when the ec2:Encrypted condition equals false.

Answer: E

Explanation:
A service control policy (SCP) is a type of policy that you can use to manage permissions in your organization. SCPs offer central control over the maximum available permissions for all accounts in your organization, allowing you to ensure your accounts stay within your organization's access control guidelines.
You can use an SCP to deny the ec2:CreateVolume action when the ec2:Encrypted condition equals false, which means that any user or role in the accounts under the root OU will not be able to create unencrypted EBS volumes. This solution will have minimal effect on employees who create EBS volumes, as they can still create encrypted volumes as needed.

NEW QUESTION # 513
A company's website hosted on Amazon EC2 instances processes classified data stored in Amazon S3 Due to security concerns, the company requires a pnvate and secure connection between its EC2 resources and Amazon S3.
Which solution meets these requirements?

  • A. Set up S3 bucket policies to allow access from a VPC endpomt.
  • B. Set up an access key ID and a secret access key to access the S3 bucket.
  • C. Set up an 1AM policy to grant read-write access to the S3 bucket.
  • D. Set up a NAT gateway to access resources outside the private subnet.

Answer: A

Explanation:
This solution meets the following requirements:
* It is private and secure, as it allows the EC2 instances to access the S3 bucket without using the public internet. A VPC endpoint is a gateway that enables you to create a private connection between your VPC and another AWS service, such as S3, within the same Region. A VPC endpoint for S3 provides secure and direct access to S3 buckets and objects using private IP addresses from your VPC. You can also use VPC endpoint policies and S3 bucket policies to control the access to the S3 resources based on the endpoint, the IAM user, the IAM role, or the source IP address.
* It is simple and scalable, as it does not require any additional AWS services, gateways, or NAT devices.
A VPC endpoint for S3 is a fully managed service that scales automatically with the network traffic.
You can create a VPC endpoint for S3 with a few clicks in the VPC console or with a simple API call.
You can also use the same VPC endpoint to access multiple S3 buckets in the same Region.

NEW QUESTION # 514
A company is planning to launch a High Performance Computing (HPC) cluster in AWS that does Computational Fluid Dynamics (CFD) simulations. The solution should scale-out their simulation jobs to experiment with more tunable parameters for faster and more accurate results. The cluster is composed of Windows servers hosted on t3a.medium EC2 instances. As the Solutions Architect, you should ensure that the architecture provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies.
Which is the MOST suitable and cost-effective solution that the Architect should implement to achieve the above requirements?

  • A. Enable Enhanced Networking with Elastic Fabric Adapter (EFA) on the Windows EC2 Instances.
  • B. Enable Enhanced Networking with Intel 82599 Virtual Function (VF) interface on the Windows EC2 Instances.
  • C. Enable Enhanced Networking with Elastic Network Adapter (ENA) on the Windows EC2 Instances.
  • D. Use AWS ParallelCluster to deploy and manage the HPC cluster to provide higher bandwidth, higher packet per second (PPS) performance, and lower inter-instance latencies.

Answer: C

Explanation:
Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types. SR-IOV is a method of device virtualization that provides higher I/O performance and lower CPU utilization when compared to traditional virtualized network interfaces. Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies. There is no additional charge for using enhanced networking.


Amazon EC2 provides enhanced networking capabilities through the Elastic Network Adapter (ENA). It supports network speeds of up to 100 Gbps for supported instance types. Elastic Network Adapters (ENAs) provide traditional IP networking features that are required to support VPC networking.
An Elastic Fabric Adapter (EFA) is simply an Elastic Network Adapter (ENA) with added capabilities. It provides all of the functionality of an ENA, with additional OS-bypass functionality. OS-bypass is an access model that allows HPC and machine learning applications to communicate directly with the network interface hardware to provide low-latency, reliable transport functionality.
The OS-bypass capabilities of EFAs are not supported on Windows instances. If you attach an EFA to a Windows instance, the instance functions as an Elastic Network Adapter, without the added EFA capabilities.
Hence, the correct answer is to enable Enhanced Networking with Elastic Network Adapter (ENA) on the Windows EC2 Instances.
Enabling Enhanced Networking with Elastic Fabric Adapter (EFA) on the Windows EC2 Instances is incorrect because the OS-bypass capabilities of the Elastic Fabric Adapter (EFA) are not supported on Windows instances. Although you can attach EFA to your Windows instances, this will just act as a regular Elastic Network Adapter, without the added EFA capabilities. Moreover, it doesn't support the t3a.medium instance type that is being used in the HPC cluster.
Enabling Enhanced Networking with Intel 82599 Virtual Function (VF) interface on the Windows EC2 Instances is incorrect because although you can attach an Intel 82599 Virtual Function (VF) interface on your Windows EC2 Instances to improve its networking capabilities, it doesn't support the t3a.medium instance type that is being used in the HPC cluster.
Using AWS ParallelCluster to deploy and manage the HPC cluster to provide higher bandwidth, higher packet per second (PPS) performance, and lower inter-instance latencies is incorrect because an AWS ParallelCluster is just an AWS-supported open-source cluster management tool that makes it easy for you to deploy and manage High Performance Computing (HPC) clusters on AWS. It does not provide higher bandwidth, higher packet per second (PPS) performance, and lower inter-instance latencies, unlike ENA or EFA.
