A company has introduced a new policy that allows employees to work remotely from their homes if they connect by using a VPN The company Is hosting Internal applications with VPCs in multiple AWS accounts Currently the applications are accessible from the company's on-premises office network through an AWS Site-to-Site VPN connection The VPC in the company's main AWS account has peering connections established with VPCs in other AWS accounts.
A solutions architect must design a scalable AWS Client VPN solution for employees to use while they work from home
What is the MOST cost-effective solution that meets these requirements?

A utility company collects usage data from smart meters every 5 minutes. Data is sent to API Gateway, processed by Lambda, and stored in DynamoDB. As usage increased, Lambda durations increased and DynamoDB PUTs failed with ProvisionedThroughputExceededException. Lambda also experiences TooManyRequestsException errors.
Which combination of changes will resolve these issues? (Select TWO.)
Comprehensive and Detailed in Depth
A is correct because write throttling on DynamoDB means WCU (write capacity units) are insufficient. Increasing them will reduce the error rate.
D is correct because introducing Kinesis allows for efficient, high-throughput ingestion and batch processing, reducing the number of Lambda invocations and overall load.
DynamoDB Throttling
Using Kinesis with Lambda
A company hosts a metadata API on Amazon EC2 instances behind an internet-facing Application Load Balancer (ALB). Only internal applications that run on EC2 instances in separate AWS accounts need to access the metadata API. All the internal EC2 instances use NAT gateways. A new policy requires that traffic between internal applications must not travel across the public internet. Which solution will meet this requirement?
An EC2-based ticketing service pulls a frequently updated pricing file (stored in S3) on startup. Sometimes EC2s have stale pricing, causing charge issues.
Mountpoint for Amazon S3allows EC2 instances to directly access files in S3 as aPOSIX-compliant mount point, ensuring they always get the latest data without copying or syncing.
It's simple and cost-effective for read-heavy patterns.
Mountpoint for Amazon S3
A company is running a web application in a VPC. The web application runs on a group of Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB is using AWS WAF.
An external customer needs to connect to the web application. The company must provide IP addresses to all external customers.
Which solution will meet these requirements with the LEAST operational overhead?
https://docs.aws.amazon.com/global-accelerator/latest/dg/about-accelerators.alb-accelerator.html Option A is wrong. AWS WAF does not support associating with NLB. https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html Option B is wrong. An ALB does not support an Elastic IP address.https://aws.amazon.com/elasticloadbalancing/features/
