When designing location-based CAC, how much overprovisioning is calculated for video bandwidth?
The correct answer is C. 20%. When designing location-based Call Admission Control in Cisco UCM, it is recommended to calculate 20% overprovisioning for video bandwidth to ensure robust performance and account for variability.

Why each option
When designing location-based Call Admission Control in Cisco UCM, it is recommended to calculate 20% overprovisioning for video bandwidth to ensure robust performance and account for variability.
10% overprovisioning is generally insufficient for video traffic due to its inherent variability and sensitivity to bandwidth fluctuations.
15% overprovisioning is below the recommended 20% for video bandwidth in CAC designs, which could lead to quality issues during peak video usage.
While more is generally better, 25% overprovisioning is not the standard design recommendation for video bandwidth in Cisco's location-based CAC and might be an unnecessary allocation of resources.
