A cloud engineer recently used a deployment script template to implement changes on a cloud-hosted web application. The web application communicates with a managed database on the back end. The engineer later notices the web application is no longer receiving data from the managed database. Which of the following is the most likely cause of the issue?

Show Suggested Answer Hide Answer
Suggested Answer: D

A misconfiguration in the firewall is the most likely cause of the issue. A firewall is a security device or service that controls the incoming and outgoing network traffic based on predefined rules. A firewall can help protect the cloud-hosted web application and the managed database from unauthorized or malicious access. However, if the firewall rules are not configured properly, they can also block the legitimate communication between the web application and the database. For example, if the firewall rules deny the port or protocol that the web application uses to connect to the database, the web application will not be able to receive data from the database. To fix this issue, the cloud engineer should review and update the firewall rules to allow the necessary traffic between the web application and the database.

Ah, good point. But wouldn't a misconfiguration in the routing traffic also cause a communication issue between the two components? It's a tough call, but I'm leaning towards that one.

You know, I was reading about these types of issues the other day, and I remember the instructor mentioning that user permissions can sometimes be the culprit. Maybe the web app doesn't have the right permissions to access the database.

I was thinking the same thing, but then I also considered the possibility of a misconfiguration in the firewall. That could be preventing the necessary traffic from reaching the database.

Hmm, this is a tricky one. I'm not entirely sure, but I think the most likely cause is a misconfiguration in the network ACL. That could be blocking the communication between the web app and the managed database.
