Domain overview
Mid Server Management covers installing, validating, and troubleshooting the Java MID Server that executes Discovery, Service Mapping, and Orchestration probes on your network. Questions test where capabilities are configured, how to read MID Server status and logs, and how to diagnose a connected-but-not-working MID Server.
Exam objectives
Configuring MID Server capabilities in the MID Server record or capabilities list to enable Discovery, Orchestration, and other tasks
Diagnosing a MID Server that shows Connected but fails Discovery, checking capability assignment, user roles, and ECC queue
Reading MID Server status, version, and logs via the MID Server record, ECC Queue, and agent logs
Verifying MID Server service state, config.xml parameters, and connectivity to the instance over the MID Web Server
Assuming a Connected MID Server is fully functional; Discovery also requires the correct capabilities, valid credentials, and a supported MID Server user role.
Editing capabilities in the wrong place, such as the instance properties, instead of the MID Server record or its capability definitions.
Ignoring the agent log and ECC queue when the service runs but the instance reports the MID Server as Down, missing network or certificate errors.

24What does the 'Heartbeat' indicate in the MID Server record?
25You want to force a MID Server to restart its service. Where can you do this?
26You need to troubleshoot why a specific WMI probe is failing. Which log should you check on the MID Server host?
27A MID Server is failing to upgrade. What should you check first?
28A MID Server is connected to the instance but 'Discovery' is not working. What is the most likely cause related to the MID Server configuration?
29What is the purpose of the 'MID Server Properties' module?
30What should you check to see if a MID Server has successfully completed a job?

32If a MID Server's memory usage is consistently high, what parameter should you tune?
33Where can you view the 'Version' of the MID Server?
34What is the primary benefit of using a MID Server?
35When using a MID Server with a custom Java version, which file must be updated to point to the new Java installation?
36When a MID Server is 'Validated', what actually happens?
37What happens to the MID Server service if the host machine reboots?
38What is the purpose of the 'mid.snmp.port' parameter?
39Which TWO pieces of information can be found in the MID Server record?

41Which TWO actions should you perform if a MID Server is not showing 'Up' in the instance?
42Which TWO settings can be managed via the MID Server 'Capabilities' feature?
43Which THREE pieces of information are required for a MID Server to communicate with the ServiceNow instance?
44Which TWO actions can be triggered from the MID Server record's related links?
45Which TWO types of discovery probes can a MID Server execute?
46Which THREE factors should be considered when planning a MID Server installation?
47Which TWO ways can you view MID Server logs?
48Which TWO files or folders are most critical for backing up a MID Server configuration?
49Which TWO categories are commonly found in the 'Capabilities' list for a MID Server?
50Which THREE conditions must be met for a MID Server to be considered 'Up'?
51A MID Server has been installed on a Windows host, but it is not appearing in the 'MID Servers' list in the ServiceNow instance. What is the first place you should check to identify the cause?
52You need to ensure that a specific MID Server only performs WMI discovery and ignores SSH tasks. How do you configure this?
53You are troubleshooting a MID Server that is stuck in the 'Validated' state but not picking up jobs. You notice the 'MID Server Issues' list reports a 'Clock drift' error. What is the recommended resolution?
54What is the purpose of the 'MID Server User' assigned to a MID Server record?
55A MID Server is configured with the IP range 10.0.0.0/24 in its MID Server IP range record. During a Discovery run, the MID Server attempts to scan a device with IP 10.0.1.5, which is outside that range. What is the outcome?

59A MID Server named MID-LON-01 must be dedicated exclusively to Discovery for the London data center, and it must not receive any other type of MID Server job. Where do you configure this restriction?
60A MID Server is configured to use a specific user account for SSH discovery of Linux servers. The discovery runs successfully for most servers, but fails for a few servers with the error 'Authentication failed'. The MID Server logs show that the SSH connection is established but the credentials are rejected. What is the most likely cause?
61Your organization uses a MID Server cluster to distribute discovery tasks. You need to ensure that a specific MID Server in the cluster is used exclusively for discovering a sensitive network segment, while other MID Servers handle general discovery. Which MID Server capability should you assign to the dedicated MID Server to achieve this?
62After installing the MID Server files on a Linux host and configuring config.xml, an administrator starts the MID Server service. The MID Server record in the instance shows a status of Up but Validated is false. What does this indicate?
63An administrator must install a MID Server on a Linux host in a data center with no direct internet access. The host can reach the instance only through an HTTP proxy. Which TWO configuration elements must be set for the MID Server to communicate through the proxy? (Choose two.)
