Show Suggested Answer

Suggested Answer: A

Here are the steps and explanations for ensuring that requests for wwwjelecloud.com from any of your Azure virtual networks resolve to frontdoor1.azurefd.net:

To use a custom domain with your Azure Front Door, you need to create a CNAME record with your domain provider that points to the Front Door default frontend host.A CNAME record is a type of DNS record that maps a source domain name to a destination domain name1.

To create a CNAME record, you need to sign in to your domain registrar's website and go to the page for managing DNS settings1.

Create a CNAME record with the following information1:

Source domain name: wwwjelecloud.com

Destination domain name: frontdoor1.azurefd.net

Save your changes and wait for the DNS propagation to take effect1.

To verify the custom domain, you need to go to the Azure portal and select your Front Door profile.Then select Domains under Settings and select Add2.

On the Add a domain page, select Non-Azure validated domain as the Domain type and enter wwwjelecloud.com as the Domain name.Then select Add2.

On the Domains page, select wwwjelecloud.com and select Verify.This will check if the CNAME record is correctly configured2.

Once the domain is verified, you can associate it with your Front Door endpoint. On the Domains page, select wwwjelecloud.com and select Associate endpoint.Then select your Front Door endpoint from the drop-down list and select Associate2.

C seems overkill for just blocking IMDS access.

Wait, can you really block IMDS like that? Sounds tricky.

I’m a bit confused about whether I should focus on inbound or outbound rules here. I thought inbound rules were more about preventing access from outside, but this seems different.

I feel like we practiced a similar question where we had to block access to a specific service. I think an outbound rule is what we used then.

I'm not entirely sure, but I think using a service tag could simplify things. It might be a good option to minimize admin effort.

I remember we discussed how the Azure Instance Metadata Service has a specific IP address, so blocking outbound traffic to that IP might be the way to go.

I'm a little confused here. Wouldn't blocking traffic to an IP address or application security group be more specific and targeted than using a service tag? I'm not sure if that would be considered "minimizing administrative effort" compared to the other options.

Okay, let me think this through. We need to prevent access to the IMDS REST API, and the question says the solution should minimize administrative effort. I'm thinking option B, the outbound rule blocking a service tag, might be the way to go. It seems like the most straightforward approach.

Hmm, I'm a bit unsure about this one. Blocking traffic to an IP address or application security group seems like it might require more manual configuration. I'm wondering if the service tag approach in option B could be the simplest solution.

I think the key here is to block access to the IMDS REST API on VM1. Based on the question, the solution should minimize administrative effort, so I'm leaning towards option B - adding an outbound rule that blocks traffic to a service tag.
