ANS-C01 Exam Dumps : Amazon AWS Certified Advanced Networking - Specialty

A network engineer needs to deploy an AWS Network Firewall firewall into an existing AWS environment. The environment consists of the following:

A transit gateway with all VPCs attached to it

Several hundred application VPCs

A centralized egress internet VPC with a NAT gateway and an internet gateway

A centralized ingress internet VPC that hosts public Application Load Balancers

On-premises connectivity through an AWS Direct Connect gateway attachment

The application VPCs have workloads deployed across multiple Availability Zones in private subnets with the VPC route table s default route (0.0.0.0/0) pointing to the transit gateway. The Network Firewall firewall needs to inspect east-west (VPC-to-VPC) traffic and north-south (internet-bound and on-premises network) traffic by using Suricata compatible rules.

The network engineer must deploy the firewall by using a solution that requires the least possible architectural changes to the existing production environment.

Which combination of steps should the network engineer take to meet these requirements? (Choose three.)

A real estate company is building an internal application so that real estate agents can upload photos and videos of various properties. The application will store these photos and videos in an Amazon S3 bucket as objects and will use Amazon DynamoDB to store corresponding metadata. The S3 bucket will be configured to publish all PUT events for new object uploads to an Amazon Simple Queue Service (Amazon SQS) queue.

A compute cluster of Amazon EC2 instances will poll the SQS queue to find out about newly uploaded objects. The cluster will retrieve new objects, perform proprietary image and video recognition and classification update metadata in DynamoDB and replace the objects with new watermarked objects. The company does not want public IP addresses on the EC2 instances.

Which networking design solution will meet these requirements MOST cost-effectively as application usage increases?

A company deploys a software solution on Amazon EC2 instances that are in a clusterplacement group. The solution's UI is a single HTML page. The HTML file size is 1,024 bytes. The software processes files that exceed 1,024 MB in size. The software shares files over the network to clients upon request. The files are shared with the Don't Fragment flag set. Elastic network interfaces of the EC2 instances are set up with jumbo frames.

The UI is always accessible from all allowed source IP addresses, regardless of whether the source IP addresses are within a VPC, on the internet, or on premises. However, clients sometimes do not receive files that they request because the files fail to travel successfully from the software to the clients.

Which options provide a possible root cause of these failures? (Choose two.)
