Mutually exclusive jobs
-
Positive dependency
-
Conditional requirement
A,B
Correct answer
Explanation
Jobs that cannot run simultaneously are related through negative dependency (mutual exclusion). Both terms describe this constraint - negative dependency is the technical CA7 term, while mutually exclusive describes the logical relationship where one job running prevents the other from starting.
-
By using some user defined(Custom) Data Queue
-
By using Microsoft Messaging Queue (MSMQ)
-
Both of the above
-
None of the above
B
Correct answer
Explanation
Microsoft Message Queue (MSMQ) is specifically designed to handle message loss and ensure reliable delivery of packets/requests. It provides queuing, guaranteed delivery, and recovery mechanisms. Custom data queues (option A) would need to implement these features from scratch.

A
Correct answer
Explanation
Win32_NetworkAdapterConfiguration WMI class contains MACAddress and IPAddress properties for network adapters. The filter IpEnabled=TRUE selects only adapters with active IP configurations. Option B and D incorrectly use Win32_NetworkAdapterDetails which is not a valid WMI class. Option C uses IpEnabled=FALSE which would return adapters without IP configuration.

SSH 22
-
TCS 8080

Correct answer
Explanation
SCOM monitors non-Windows devices (like Unix/Linux) through SSH on port 22. The agentless monitoring uses SSH to communicate with the target system. The other options are incorrect protocols/ports for this purpose.

500 bytes per sec
-
600 bytes per sec
-
700 bytes per sec
-
800 bytes per sec
A
Correct answer
Explanation
The Management Server communicates with SCOM agents primarily for health heartbeat and data collection. Typical agent communication is lightweight, involving small heartbeat signals and performance data at regular intervals. 500 bytes per second is the standard documented average bandwidth utilization for normal SCOM agent operations.
