                                                  NEW QUESTION # 265
                                                  A European government passport agency considers upgrading its IT systems to increase performance and workload flexibility in response to constantly changing requirements.

                                                  Answer: B


                                                  NEW QUESTION # 266
                                                  Which undesired effect of increasing the jitter compensation buffer is true?

                                                  Answer: B

                                                  Explanation:
                                                  * Increasing jitter buffer size smoothens jitter but at the cost of introducing additional delay.
                                                  * Excessive jitter buffering can lead to perceptible audio or video lag, impacting user experience.
                                                  * C: Therefore, the undesired effect is increased transport delay, potentially leading to quality issues if the buffer size is too large.
                                                  Why other options are incorrect:
                                                  * A & D: Jitter buffering does not improve jitter itself; it masks it at the expense of delay.
                                                  * B: Jitter compensation doesn't increase jitter, but delay.
