Which Milestone XProtect component is responsible for storing video streams and
providing playback of recorded footage?
A) Management Server
B) Event Server
C) Recording Server
D) Mobile Server
Correct Answer: C
Explanation: The Recording Server handles video ingestion, storage, and serves recorded
footage to clients. The Management Server stores the system configuration, the Event
Server processes alarms, and the Mobile Server enables remote access.
SAMPLE QUESTION 2
In a surveillance camera, a larger sensor size primarily improves what aspect of image
quality?
A) Lens focal length
B) Low-light performance and dynamic range
C) Network bandwidth usage
D) Frame rate capability
Correct Answer: B
Explanation: Larger sensors collect more light, enhancing low-light sensitivity and dynamic
range. Focal length, bandwidth, and frame rate are not directly determined by sensor size.
,SAMPLE QUESTION 3
When calculating required storage for a 30-day retention period of 16 cameras
recording at 1080p, 15 fps, with H.264 compression at 4 Mbps each, what is the correct
total bitrate?
A) 480 Mbps
B) 64 Mbps
C) 960 Mbps
D) 32 Mbps
Correct Answer: B
Explanation: 16 cameras multiplied by 4 Mbps equals a total bitrate of 64 Mbps. Over 30
days, this requires approximately 165 TB of storage. The calculation is: 64 Mbps × 86,400
seconds per day × 30 days, converted to terabytes.
SAMPLE QUESTION 4
Which RAID level offers both striping for performance and dual parity for fault
tolerance?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 6
Correct Answer: D
Explanation: RAID 6 provides striping for performance and dual parity, allowing the
system to survive two simultaneous disk failures. RAID 0 offers no redundancy, RAID 1 is
mirroring, and RAID 5 offers single parity.
SAMPLE QUESTION 5
Which network protocol is most appropriate for real-time, low-latency video streaming
in a VMS environment?
A) TCP
B) FTP
C) RTP over UDP
D) HTTP
,Correct Answer: C
Explanation: RTP (Real-time Transport Protocol) over UDP provides time-synchronized
delivery with minimal overhead, ideal for live video. TCP guarantees delivery but
introduces latency, making it less suitable for real-time streaming.
SAMPLE QUESTION 6
In a GDPR-compliant surveillance design, what is the most important consideration?
A) Using only analog cameras
B) Storing video footage for the shortest period necessary for the purpose
C) Encrypting network cables with fiber optics
D) Providing 4K resolution for all cameras
Correct Answer: B
Explanation: GDPR mandates data minimization, meaning footage should be retained
only as long as needed for its legitimate purpose. This is a core principle of privacy-
compliant video system design.
SAMPLE QUESTION 7
For a VMS deployment requiring 24/7 operation with zero downtime, what is the
recommended Milestone architecture?
A) A single Recording Server with RAID 0
B) Dual Recording Servers in a failover configuration
C) Only the Management Server with cloud storage
D) A Mobile Server as primary storage
Correct Answer: B
Explanation: A failover configuration ensures that a secondary Recording Server
automatically takes over if the primary fails, providing high availability. RAID 0 offers no
redundancy, and the Mobile Server is not for primary storage.
SAMPLE QUESTION 8
Which of the following is a recommended practice for hardening a Milestone VMS
, against cyber threats?
A) Disabling all user authentication
B) Using default admin passwords
C) Enabling TLS encryption for client-server communication
D) Allowing unrestricted internet access to all cameras
Correct Answer: C
Explanation: TLS encryption protects credentials and video streams from interception.
Disabling authentication and using default passwords are major security vulnerabilities.
Cameras should not be exposed directly to the internet.
SAMPLE QUESTION 9
In XProtect, the Failover Server is primarily used for what purpose?
A) Store backup licenses
B) Provide a standby Recording Server that automatically takes over if the primary fails
C) Host the mobile client application
D) Generate synthetic video streams for testing
Correct Answer: B
Explanation: The Failover Server mirrors the primary Recording Server's configuration and
can assume its role during outages. This is critical for maintaining system uptime and
continuous recording.
SAMPLE QUESTION 10
Which compression technique is most efficient for reducing bandwidth while preserving
image quality in modern IP cameras?
A) MJPEG
B) H.264
C) MPEG-2
D) Motion JPEG
Correct Answer: B
Explanation: H.264 (AVC) provides significantly better compression efficiency than MJPEG
or MPEG-2, making it the standard for modern surveillance systems. H.265 offers even
better efficiency but may require more processing power.
