Your company has offices in Montreal. Seattle, and Paris. The outbound traffic from each office originates from a specific public IP address.
You create an Azure Front Door instance named FD1 that has Azure Web Application Firewall (WAF) enabled. You configure a WAF policy named Policy! that has a rule named Rule1. Rule1 applies a rate limit of 100 requests for traffic that originates from the office in Montreal.
You need to apply a rate limit of 100 requests for traffic that originates from each office.

I thought you could just adjust the conditions instead.

Modifying Rule1 won't cover all offices, so B makes sense.

Wait, can you really apply the same rate limit to different IPs like that?

Totally agree, option B is the way to go!

Just need to create two more rules for the other offices.

I thought we had to change the rule type for it to apply to different sources, but now I'm questioning if that's necessary.

I feel like modifying the conditions of Rule1 could work, but I can't recall if that would apply to all offices or just Montreal.

This seems similar to a practice question where we had to create multiple rules for different IPs. I think creating additional associations might be the way to go.

I remember we discussed how to apply rate limits in WAF policies, but I'm not sure if modifying Rule1 is enough for all offices.

Hmm, this one has me a bit stumped. I know we covered custom metadata types in class, but I'm having trouble remembering the specific data types involved. I'll need to think this through carefully.

Okay, let me see here. The question mentions the customer is redirected to a page to download the app, so that rules out SMTP which is for email. I'm leaning towards HTTP or HTTPS, but I'll have to double-check the differences between those two protocols.

Okay, I've got this. The solution is to ensure the users have the server certificate installed on their devices. That should resolve the trust issue.

I'm leaning towards "All of the above," but I can't quite recall if understanding by the person being arrested is actually necessary.

On the conditions rule, we can set more than one IP

You decide to create a rate-limit rule that restricts each source IP address to a maximum of 1,000 requests per minute

Requests from the same client often arrive at the same Azure Front Door server. In that case, you see requests are blocked as soon as the rate limit is reached for each of the client IP addresses
