Edge computing places resources and content closer to the geographic location of users, reducing latency and enabling faster access compared to centralized cloud resources.

The best way to grant full access to a specific cloud resource to a branch in Spain, while other branches have only read access, is to create a network security group with the required permissions.
This group can be configured to allow full access to users within the branch's IP range while restricting others to read-only access.

A non-relational (NoSQL) database is the best choice for storing unstructured and frequently changing data. Unlike relational databases, which require fixed schemas and structured data, NoSQL databases offer flexibility and scalability, making them ideal for handling varied data formats such as JSON, XML, videos, and logs.

A contractual agreement is a mutually binding obligation between parties that can mandate specific security requirements such as encrypting exchanged data.

After a WAF deployment fails to prevent an exploit, adding an Access Control List (ACL) to the Virtual Machine (VM) subnet can be an effective control. ACLs provide an additional layer of security by explicitly defining which traffic can or cannot enter a network segment. By setting granular rules based on IP addresses, protocols, and ports, ACLs help to restrict access to resources, thereby mitigating potential exploits and enhancing the security of the IaaS network.
