(MCDE) Exam Questions And Answers
With Verified Study Solutions Rated A+
Question 1
What is the maximum number of Recording Servers that a single Milestone XProtect
Corporate Management Server can manage?
A) 25
B) 100
C) 250
D) Unlimited
Answer: B
Explanation: In XProtect Corporate, the Management Server can handle up to 100
Recording Servers. This limit ensures database and communication performance.
Exceeding it degrades configuration synchronization and event handling.
Question 2
Which Milestone product uses a "Failover Recording Server" as a dedicated hot-
standby?
A) XProtect Essential+
B) XProtect Professional+
C) XProtect Express+
D) XProtect Corporate
Answer: D
Explanation: XProtect Corporate supports a dedicated Failover Recording Server that
,remains idle until a primary fails. Lower-tier products use "failover recording" where any
server can take over, but Corporate offers a dedicated, priority-based model.
Question 3
When designing a system with 500 cameras, each recording at 4 Mbps, what is the
minimum aggregate network switch throughput required?
A) 500 Mbps
B) 1 Gbps
C) 2 Gbps
D) 4 Gbps
Answer: C
Explanation: 500 cameras × 4 Mbps = 2000 Mbps = 2 Gbps. This is the minimum
required for video traffic alone. Milestone recommends adding 20-30% overhead for
management and burst traffic, so a 2.5 Gbps capable switch would be safer.
Question 4
What is the purpose of the "Time Zone" setting in an XProtect Recording Server?
A) Only for display in Smart Client
B) To align database maintenance schedules
C) To timestamp recordings and events consistently across servers
D) To control user login hours
Answer: C
Explanation: The Recording Server’s time zone ensures that all recorded video and
metadata use a consistent time reference. If servers are in different physical time zones,
the Management Server normalizes to UTC, but each server’s local time setting is critical
for alarm correlation.
,Question 5
A customer wants to archive video to a network drive after 30 days. Which Milestone
feature enables this?
A) Archiving via Storage Profile
B) Database trimming
C) Edge storage only
D) Manual export
Answer: A
Explanation: XProtect uses Storage Profiles to define retention times and archiving
paths. You can set a primary storage (fast local) and an archive storage (slower network
drive). After the defined period, the Recording Server moves older recordings to the
archive location.
Question 6
In XProtect, what is the function of a "hardware driver"?
A) To provide network authentication
B) To translate proprietary camera commands into Milestone commands
C) To encrypt video streams
D) To manage failover priorities
Answer: B
Explanation: Hardware drivers are device-specific plugins that allow Milestone to
communicate with cameras, encoders, and I/O modules. They convert generic Milestone
requests (PTZ, zoom, settings) into the manufacturer’s specific API or protocol.
, Question 7
A site has two Recording Servers: RS1 and RS2. RS1 fails. Using failover recording, RS2
takes over RS1’s cameras. What happens when RS1 comes back online?
A) RS2 continues recording RS1’s cameras permanently
B) RS1 automatically reclaims its cameras after 5 minutes
C) Administrator must manually fail back
D) RS2’s recording stops and RS1 resumes
Answer: C
Explanation: In failover recording (Professional+, Expert, Corporate), the failover
Recording Server continues recording until an administrator manually fails back.
Automatic failback is not supported to prevent data loss or conflicts.
Question 8
How many archiving paths can a single Recording Server use simultaneously?
A) 1
B) 4
C) 8
D) 16
Answer: B
Explanation: A Recording Server supports up to 4 archiving paths (destinations). Each
can have different retention rules. This allows tiered storage (e.g., fast SSD → HDD →
NAS → cloud), but only one path is active per recording.
Question 9
What is the maximum number of cameras supported on a single Recording Server in
XProtect Corporate (without failover)?
