300-070 Question #32: Real Exam Question with Answer & Explanation

The correct answer is A: PVDM3-256. Heterogeneous conferencing requires DSPs capable of transcoding (converting between different codecs) and transrating/trans-sizing (converting between different bit rates or frame sizes). Only third-generation PVDM3 modules with sufficient capacity support these advanced DSP feat

Question

Which two of the following DSPs can be used in heterogenous conferencing to achieve the required trans- sizing and transcoding functionality? (Choose two.)

Options

APVDM3-256
BPVDM2-256
CPVDM-192
DPVDM3-32
EPVDM3-192
FPVDM2-128

Explanation

Heterogeneous conferencing requires DSPs capable of transcoding (converting between different codecs) and transrating/trans-sizing (converting between different bit rates or frame sizes). Only third-generation PVDM3 modules with sufficient capacity support these advanced DSP features. Specifically, PVDM3-256 (A) and PVDM3-192 (E) have the processing power and firmware support required for heterogeneous conferencing. Older PVDM2 modules (PVDM2-256, PVDM2-128) lack the necessary DSP architecture to perform the transcoding functions required for heterogeneous video conferencing. The PVDM3-32 (D) is a PVDM3 but has insufficient DSP resources (too few channels) to support the transcoding and trans-sizing workload. Always choose PVDM3 high-density modules for heterogeneous conferencing deployments.
