You deploy an Amazon EC2 instance that runs a web server into a subnet in a VPC. An Internet gateway is attached, and the main route table has a default route (0.0.0.0/0) configured with a target of the Internet gateway.
The instance has a security group configured to allow as follows:
Protocol: TCP
Port: 80 inbound, nothing outbound
The Network ACL for the subnet is configured to allow as follows:
Protocol: TCP
Port: 80 inbound, nothing outbound
When you try to browse to the web server, you receive no response.
Which additional step should you take to receive a successful response?
An organization runs a consumer-facing website on AWS. The Amazon EC2-based web fleet is load balanced using the AWS Application Load Balancer, Amazon Route 53 is used to provide the public DNS services.
The following URLs need to server content to end users:
test.example.com
web.example.com
example.com
Based on this information, what combination of services must be used to meet the requirement? (Select two.)
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 uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS
account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct
Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for
each connection.
What is the MOST scalable way to add VPCs with on-premises connectivity?
A company has an application running on Amazon EC2 instances in a VPC The application must publish custom metrics to Amazon CloudWatch in the same AWS Region The metrics include proprietary information All connectivity must be over private IP addresses.
