Which three statements describe a characteristic of profiles. (Choose three.)
The correct answer is A. Default profiles cannot be created or deleted. B. Custom profiles are always based on a parent profile. C. A profile can be a child of one profile and a parent of another.. Profiles on the BIG-IP system exhibit a hierarchical structure where default profiles are fixed, custom profiles inherit from parents, and profiles can act as both child and parent in the hierarchy.
Question

- ADefault profiles cannot be created or deleted.
- BCustom profiles are always based on a parent profile.
- CA profile can be a child of one profile and a parent of another.
- DAll changes to parent profiles are propagated to their child profiles.
- EWhile most virtual servers have at least one profile associated with them, it is not required.

Why each option
Profiles on the BIG-IP system exhibit a hierarchical structure where default profiles are fixed, custom profiles inherit from parents, and profiles can act as both child and parent in the hierarchy.
Default profiles (e.g., tcp, http) are system-defined and serve as templates; they cannot be created or deleted by users.
Custom profiles are always based on a parent profile, inheriting its settings and allowing for specific modifications.
A profile can be a child of a higher-level profile (inheriting its settings) and simultaneously act as a parent for other custom profiles created from it.
While child profiles inherit settings from their parents, changes to a parent profile are not automatically propagated or forced onto existing child profiles if those specific settings have been explicitly overridden in the child.
Virtual servers always require at least a TCP profile, as it defines the fundamental connection behavior; it is a mandatory association.
