Common mistakes.
- B. This option includes both primary and backup preferred colors with an SLA class, which is a complete configuration, but choice A is more specific if the question implicitly focuses only on the backup scenario.
- C. This option incorrectly uses
SLA Class Managementinstead ofData_SLAfor data traffic, which is critical for meeting the 'data SLA' requirement, and also includesStrictenforcement not specified in the requirements. - D. This option includes
Strictenforcement for the SLA class, which was not explicitly stated in the requirements and implies a more aggressive traffic handling if SLA is violated.
