SAA-C03 Exam Questions Tutorials

A gateway endpoint is a gateway that is a target for a specified route in your routetable, used for traffic destined to a supported AWS service1. Amazon S3 does not support gateway endpoints, only interface endpoints2. Therefore, option A is incorrect.

An interface endpoint is an elastic network interface with a private IP address that serves as an entry point for traffic destined to a supported service1. An interface endpoint can provide secure access toAmazon S3 from within the Region, but not from the on-premises location. Therefore, option C is incorrect.

AWS Key Management Service (AWS KMS) is a service that allows you to create and manage encryption keys to protect your data3. AWS KMS does not provide a way to access data on Amazon S3 without traversing the internet. Therefore, option D is incorrect.

AWS Transit Gateway is a service that enables you to connect your Amazon Virtual Private Clouds (VPCs) and your on-premises networks to a single gateway. You can create a gateway in AWS Transit Gateway to access Amazon S3 securely from both the Region and the on-premises location using AWS Direct Connect. Therefore, option B is correct.

Deny the request from the first entry at the public subnet, dont allow it to cross and get to the private subnet.

In this scenario, the security audit reveals that the application is receiving millions of illegitimate requests from a small number of IP addresses. To address this issue, it is recommended to modify the network ACL (Access Control List) for the web tier subnets. By adding an inbound deny rule specifically targeting the IP addresses that are consuming resources, the network ACL can block the illegitimate traffic at the subnet level before it reaches the web servers. This will help alleviate the excessive load on the web tier and improve the application's performance.

An egress-only internet gateway is a VPC component that allows outbound communication over IPv6 from instances in your VPC to the internet, and prevents theinternet from initiating an IPv6 connection with your instances. This meets the company’s security policy and requirements. To use an egress-only internet gateway, you need to add a route in the subnet’s route table that routes IPv6 internet traffic (::/0) to the egress-only internet gateway.

Amazon Macie can also send its findings to Amazon EventBridge, which is a serverless event bus that makes it easy to connect applications using data from a variety of sources. You can create an EventBridge rule that filters the SensitiveData event type from Macie findings and sends an Amazon SNS notification to the security team. Amazon SNS is a fully managed messaging service that enables you to send messages to subscribers or other
