Milestone Certified Design Engineer (MCDE) Exam: 170 Questions and Answers
QUESTION 1:
Which of the following best describes the primary role of a Milestone Certified Design Engineer
(MCDE) in a video surveillance project?
A. Operating and maintaining existing CCTV systems
B. Designing network architecture and recommending compatible hardware for Milestone
XProtect
C. Installing cameras and terminating cables
D. Managing video analytics configuration only
CORRECT ANSWER: B
RATIONALE: The MCDE focuses on system design—selecting proper architecture, hardware, and
configurations that support Milestone XProtect performance and scalability.
QUESTION 2:
When calculating storage requirements in a Milestone XProtect system, which parameter is not
typically part of the formula?
A. Frame rate
B. Resolution
C. Bitrate per stream
D. Lens aperture size
CORRECT ANSWER: D
RATIONALE: Frame rate, resolution, and bitrate determine data size. Lens aperture affects image
quality but not storage duration directly.
QUESTION 3:
True or False: Milestone XProtect Expert and XProtect Corporate support multi-server and
distributed site management.
CORRECT ANSWER: True
RATIONALE: Both Expert and Corporate editions are designed for large and distributed systems,
allowing centralized management across multiple servers.
,QUESTION 4:
In a large-scale Milestone system, which network topology offers the best fault tolerance?
A. Bus topology
B. Star topology
C. Ring topology
D. Mesh topology
CORRECT ANSWER: D
RATIONALE: Mesh topology provides multiple data paths, ensuring redundancy and resilience
against link failure, crucial in enterprise video systems.
QUESTION 5:
Which of the following features is exclusive to XProtect Corporate among Milestone editions?
A. Multi-layer maps
B. Federated Architecture
C. Role-based access control
D. Smart Client support
CORRECT ANSWER: B
RATIONALE: Federated Architecture enables centralized control over multiple sites—this is a key
differentiator of the Corporate edition.
QUESTION 6:
The recommended recording server CPU load threshold should generally not exceed which
percentage for stable operation?
A. 30%
B. 50%
C. 70%
D. 90%
CORRECT ANSWER: C
RATIONALE: Staying below 70% CPU load ensures headroom for spikes and sustained stability
during simultaneous encoding and data processing.
,QUESTION 7:
Short Answer:
Explain why separate network segments are often recommended for video traffic and
management traffic in Milestone system design.
CORRECT ANSWER: Segregating traffic prevents management commands from being
delayed by high video throughput and improves both security and performance.
RATIONALE: Dedicated segmentation reduces latency, isolates failures, and maintains bandwidth
for video data without impacting control functions.
QUESTION 8:
When using multi-streaming in XProtect, why might you assign different resolutions to live and
recorded streams?
A. To improve night vision only
B. To reduce power consumption
C. To optimize bandwidth and storage efficiency
D. To avoid lens distortion
CORRECT ANSWER: C
RATIONALE: Lower resolution or frame rate for recording conserves storage, while high-quality
live streams maintain situational awareness.
QUESTION 9:
Which disk configuration provides the best compromise between performance and redundancy
for a recording server?
A. RAID 0
B. RAID 1
C. RAID 5
D. JBOD
CORRECT ANSWER: C
RATIONALE: RAID 5 offers both fault tolerance and good read/write performance, ideal for video
storage scenarios.
QUESTION 10:
, True or False: Using SSD drives for recording is always more cost-effective than HDD drives in
Milestone systems.
CORRECT ANSWER: False
RATIONALE: While SSDs are faster, large video archives require high-capacity disks at lower
cost—HDDs are typically more economical per terabyte.
QUESTION 11:
What is the primary function of the Event Server in XProtect architecture?
A. Recording raw video streams
B. Managing system licensing
C. Handling alarms, metadata, and system events
D. Providing client authentication
CORRECT ANSWER: C
RATIONALE: The Event Server consolidates system events, analytics metadata, and alarm
management functions into a centralized process.
QUESTION 12:
Which version of XProtect allows for encryption of recorded video using secure recording?
A. Essential+
B. Express+
C. Expert
D. Corporate
CORRECT ANSWER: D
RATIONALE: Secure recording is available in XProtect Corporate to ensure encrypted and tamper-
resistant archival storage.
QUESTION 13:
In a redundancy design, which component ensures automatic failover between primary and
secondary recording servers?
A. Windows Cluster Service
B. Milestone Failover Recording Server
