Explanation
In R81.10, dbedit scripts are being replaced by the mgmt_cli utility for managing and configuring security policies and objects. Here's an explanation of each option:
A: dbedit is not supported in R81.10: This is not entirely accurate. While dbedit is still available and functional in R81.10, it is being phased out in favor of mgmt_cli for policy and object management.
B: dbedit is fully supported in R81.10: This statement is not accurate because although dbedit can still be used, it is not the primary recommended tool for policy management in R81.10.
C: You can use dbedit to modify threat prevention or access policies, but not create or modify layers: This statement is partially true, but it does not provide the complete picture. You can use dbedit for some policy-related tasks, but it's not the primary tool for policy management in R81.10.
D: dbedit scripts are being replaced by mgmt_cli in R81.10: This is the correct and recommended approach.
mgmt_cli is the primary tool for managing security policies and objects in R81.10, and it is gradually replacing dbedit for these tasks.
Therefore, option D is the most accurate and recommended answer.
