The reason for the failure is that detections for MD5 signatures must be configured in the advanced custom detection policies, not in the simple detection policy section. The simple detection policy section allows users to create a list of SHA-256 hashes of files that they want to block or quarantine on the endpoints. The SHA-256 hash is a more secure and unique identifier of a file than the MD5 hash, which can have collisions or duplicates. The advanced custom detection policy section allows users to create more complex and flexible rules to detect and block files based on various criteria, such as file name, size, type, signature, or MD5 hash. The advanced custom detection policy section also supports wildcards and regular expressions to match multiple files or patterns. Therefore, if the administrator wants to add specific MD5 signatures to the custom detection policy, they should use the advanced custom detection policy section instead of the simple detection policy section.

A destination list is a list of internet destinations: domains, URLs, and CIDRs. To control identity access to specific destinations, you can add destination lists to Umbrella and then select them when configuring your Web and DNS policies12. When you add or edit a destination list, the changes are applied immediately if the destination list is part of a policy3. This means that any identities that are associated with the policy will be affected by the changes in the destination list. You do not need to save the configuration or remove the destination list from the policy to apply the changes. However, you do need to have the appropriate user role to manage destination lists. The user role of Block Page Bypass or higher is needed to perform these changes4. References :=

Microsegmentation is a network security strategy that breaks a network into smaller network “segments” to boost security and control over data traffic1. Unlike traditional network security, which primarily defends the network’s outer boundaries, microsegmentation focuses on securing individual workloads and devices within the network2. Microsegmentation uses an allow-list model to significantly reduce the attack surface across different workload types and environments3. Microsegmentation is also referred to as application segmentation or east-west segmentation in a multicloud data center4.

Option B is the correct description of microsegmentation, as it captures the essence of applying a zero-trust model and specifying how applications on different servers or containers can communicate. Option A is incorrect, as deploying a container orchestration platform is not a sufficient condition for microsegmentation. Option C is incorrect, as deploying host-based firewall rules is not a necessary condition for microsegmentation. Option D is incorrect, as implementing private VLAN segmentation is a different technique from microsegmentation. References: An Introduction to Microsegmentation in Network Security. What Is Micro-Segmentation? - Cisco. What Is Microsegmentation? - Palo Alto Networks. What Is Microsegmentation in Networking?
