101 Question #490: Real Exam Question with Answer & Explanation
The correct answer is D: Active-standby is less complex to troubleshoot. Active-standby HA configurations are simpler to troubleshoot than active-active because only one device processes traffic at a time, reducing diagnostic complexity.

Question
What advantage does an active-standby configuration have over an active-active configurations?
Options
- AActive-standby configuration allows for the backup of the peer configuration
- BActive-standby utilizes the hardware more efficiently
- CActive standby Uses significantly less power consumption than active-active
- DActive-standby is less complex to troubleshoot
Explanation
Active-standby HA configurations are simpler to troubleshoot than active-active because only one device processes traffic at a time, reducing diagnostic complexity.
Common mistakes.
- A. Both active-standby and active-active configurations support configuration synchronization between peer devices, so this is not a distinguishing advantage unique to active-standby.
- B. Active-active configurations utilize hardware more efficiently because both devices process traffic simultaneously, so active-standby is actually less hardware-efficient.
- C. Power consumption differences between the two models are negligible because both configurations require all devices to remain fully powered on and operational at all times.
