The correct answer is to configure a network file share as an internal update source for Microsoft Defender Antivirus. This works because Microsoft Defender for Endpoint supports using a UNC path as a fallback location for definition updates, allowing servers to pull the latest antivirus signatures from a shared folder on the local network rather than requiring internet connectivity. On the MD-102 exam, this scenario tests your understanding of how to maintain endpoint protection in air-gapped or disconnected environments, a common challenge for enterprise server management. A frequent trap is choosing the Microsoft Update Catalog, which only provides manual downloads and no automatic update mechanism, or Intune, which is designed for client management rather than server definition distribution. Remember the tip: “Share the load, not the internet”—a file share keeps definitions current when the cloud is out of reach.

Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
