Amazon PAS-C01 Exam - Topic 1 Question 10 Discussion

Actual exam question for Amazon's PAS-C01 exam

Question #: 10
Topic #: 1

A company is planning to move all its SAP applications to Amazon EC2 instances in a VPC Recently the company signed a multiyear contract with a payroll software-as-a-service (SaaS) provider integration with the payroll SaaS solution is available only through public web APIs.

Corporate security guidelines state that all outbound traffic must be validated against an allow list. The payroll SaaS provider provides only fully qualified domain name (FQDN) addresses and no IP addresses or IP address ranges Currently, an on-premises firewall appliance filters FQDNs. The company needs to connect an SAP Process Orchestration (SAP PO) system to the payroll SaaS provider.

What must the company do on AWS to meet these requirements?

AAdd an outbound rule to the security group of the SAP PO system to allow the FODN of the payroll SaaS provider and deny all other outbound traffic

BAdd an outbound rule to the network ACL of the subnet that contains the SAP PO system to allow the FQDN of the payroll SaaS provider and deny all other outbound traffic

CAdd an AWS WAF web ACL to the VPC Add an outbound rule to allow the SAP PO system to connect to the FQDN of the payroll SaaS provider

DAdd an AWS Network Firewall firewall to the VPC Add an outbound rule to allow the SAP PO system to connect to the FQDN of the payroll SaaS provider

Definitely need to use D for better security.

Wait, can we really filter FQDNs like that?

I think B might be better for subnet control.

Sounds like option A is the way to go!

I think option D sounds promising since AWS Network Firewall can handle more complex rules, but I’m unsure if it’s necessary for just allowing an FQDN.

I feel like AWS WAF is more for web applications, so I'm hesitant about option C. It seems like it wouldn't fit the requirement for validating outbound traffic.

This question seems similar to one we practiced about managing outbound rules. I think using a network ACL might be the right approach, but I can't recall the specifics.

I remember we discussed the importance of security groups for controlling outbound traffic, but I'm not sure if they can filter by FQDN directly.

Okay, I've got a good feeling about this one. The time range selected must be the key factor in how the data is bucketed, right? I'll mark that as my answer.

This question seems pretty straightforward. I'm pretty confident that the correct answer is C - an EMR is electronically stored information about an individual's health status and health care.

This reminds me of a practice question about denial-of-service attacks where the computer had similar symptoms. I wonder if that's the right answer here too?

I'm just wondering if the payroll SaaS provider has a sense of humor and accepts 'payroll@juggernaut.com' as an FQDN. Worth a shot, right?

Yeah, that way we can ensure that only the necessary outbound traffic is allowed.

Adding an outbound rule to the security group of the SAP PO system seems like the best option.

That's a creative idea, but I don't think it will work. We need to follow the guidelines.

Option A is simple, but I don't know if I'd trust a security group to handle this critical requirement. Better to use a dedicated firewall solution.

Hmm, Option C with the AWS WAF web ACL sounds interesting, but I'm not sure if that's the best fit for this scenario. Seems a bit overkill.

I think Option D is the way to go. Adding an AWS Network Firewall and configuring the outbound rule seems like a more robust solution than just using a security group.

I'm leaning towards option C, adding an AWS WAF web ACL for extra protection.

Option B seems the most straightforward way to meet the requirements. Allowing only the FQDN of the payroll SaaS provider through the network ACL is a good approach.
