SAA-C02 문제 16

A company is creating an architecture for a mobile app that requires minimal latency for its users. The company's architecture consists of Amazon EC2 instances behind an Application Load Balancer running in an Auto Seating group The EC2 instances connect to Amazon RDS Application beta testing showed there was a slowdown when reading the data However, the metrics indicate that the EC2 instances do not cross any CPU utilization thresholds
How can this issue be addressed?

A. Add read replicas for the RDS instances and direct read traffic to the replica

B. Add Multi-AZ support to the RDS instances and direct read traffic to the new EC2 instance

C. Replace the Application Load Balancer with a Network Load Balancer.

D. Reduce the threshold for CPU utilization in the Auto Scaling group

A company's near-real-time streaming application is running on AWS. As the data is ingested, a job runs on the data and takes 30 minutes to complete. The workload frequently experiences high latency due to large amounts of incoming data A solutions architect needs to design a scalable and serverless solution to enhance performance.
Which combination of steps should the solutions architect take? (Select TWO.)

A. Use AWS Lambda with AWS Step Functions to process the data.

B. Use AWS Database Migration Service (AWS DMS) to ingest the data.

C. Use AWS Fargate with Amazon Elastic Container Service (Amazon ECS) to process the data.

D. Use Amazon EC2 instances in an Auto Scaling group to process the data

E. Use Amazon Kinesis Data Firehose to ingest the data

A company hosts a training site on a fleet of Amazon EC2 instances. The company anticipates that its new course which consists of dozens of training videos on the site, will be extremely popular when it is released in 1 week
What should a solutions architect do to minimize the anticipated server load?

A. Store the videos in Amazon ElastiCache for Redis Update the web servers to serve the videos using the ElastiCache API

B. Store the videos m an Amazon S3 bucket Create an Amazon CloudFront distribution with an origin access identity (OAl) of that S3 bucket Restrict Amazon S3 access to the OAl

C. Store the videos in an Amazon S3 bucket Create an AWS Storage Gateway file gateway to access the S3 bucket Create a user data script for the web servers to mount the file gateway.

D. Store the videos m Amazon Elastic File System (Amazon EFS) Create a user data script for the web servers to mount the EPS volume

SAA-C02 문제 19

A solutions architect It designing a VPC with public and private subnets. The VPC and subnets use IPv4 CIDR blocks. There is one public subnet and one private subnet in each of three Availability Zones (AZs) for high availability An internet gateways used to provide internet access for the public subnets. The private subnets require access to the internet to allow Amazon BC2 Instances to download software updates.
What should the solutions architect do to enable internet access for the private subnets?

A. Create three NAT instances, one for each private subnet in each AZ Create a private route table for each AZ that forwards non-VPC traffic to the NAT instance in its AZ.

B. Create a second internet gateway on one of the private subnets. Update the route table for the private subnets that forward non-VPC trade to the private Internet gateway.

C. Create an egress-only internet gateway on one of the pubic subnets. Update the route table for the private subnets that forward non-VPC traffic to the egress-only internet gateway.

D. Create three NAT gateways, one for each public subnet in each AZ Create a private route table for each AZ that forwards non-VPC traffic to tie NAT gateway m its AZ.

A company is using Amazon Route 53 latency-based routing to route requests to its UDP-based application for users around the world. The application is hosted on redundant servers in the company's on-premises data centers in the United States. Asia, and Europe. The company's compliance requirements state that the application must be hosted on premises The company wants to improve the performance and availability of the application
What should a solutions architect do to meet these requirements?

A. Configure three Network Load Balancers (NLBs) in the three AWS Regions to address the on-premises endpoints In Route 53. create a latency-based record that points to the three NLBs. and use it as an origin for an Amazon CloudFront distribution Provide access to the application by using a CNAME that points to the CloudFront DNS

B. A Configure three Network Load Balancers (NLBs) in the three AWS Regions to address the on-premises endpoints Create an accelerator by using AWS Global Accelerator, and register the NLBs as its endpoints. Provide access to the application by using a CNAME that points to the accelerator DNS

C. Configure three Application Load Balancers (ALBs) in the three AWS Regions to address the on-premises endpoints In Route 53 create a latency-based record that points to the three ALBs and use it as an origin for an Amazon CloudFront distribution- Provide access to the application by using a CNAME that points to the CloudFront DNS

D. Configure three Application Load Balancers (ALBs) in the three AWS Regions to address the on-premises endpoints. Create an accelerator by using AWS Global Accelerator and register the ALBs as its endpoints Provide access to the application by using a CNAME that points to the accelerator DNS
