SERVICENOW-CIS-DISCOVERY Mid Server Management Practice Test 4 — 15 Questions

Question 1

A MID Server reports 'Up' but is not processing any jobs. What is the most likely cause?

Accepted Answer

The MID Server is paused. If a MID Server is paused, it will remain up but will not poll for work from the ECC Queue.

Answer

The MID Server is in a cluster

Answer

The MID Server is not validated

Answer

The MID Server is missing the 'Discovery' capability

Question 2

You need to ensure a specific MID Server only performs WMI scanning. How do you configure this?

Accepted Answer

Update the Capabilities list on the MID Server record. Capabilities are used to restrict or assign specific types of work to a MID Server. Removing other capabilities ensures it only handles WMI tasks.

Answer

Change the MID Server status to 'Validated'

Answer

Modify the Application settings on the MID Server record

Answer

Assign it to a MID Server Cluster

Question 3

What is the purpose of the 'MID Server Validation' process?

Accepted Answer

To provide a security handshake between the instance and the MID Server. Validation ensures that the MID Server is trusted by the instance and authorized to execute commands.

Answer

To check for the latest software version

Answer

To verify the network speed to the instance

Answer

To confirm the MID Server has enough RAM

Question 4

You need to upgrade a large number of MID Servers. Which feature should you use to avoid manual updates?

Accepted Answer

MID Server Auto-Upgrade. MID Server Auto-Upgrade is the built-in feature that automatically upgrades MID Servers to match the instance version, eliminating manual patching across a large fleet. When enabled, the instance pushes the upgrade package to each MID Server, which then updates itself and restarts. This is the standard approach for managing many MID Servers at scale.

Answer

MID Server Update Sets

Answer

MID Server Cluster Overrides

Answer

Scheduled Jobs to restart services

Question 5

What is the primary function of the 'MID Server' application in ServiceNow?

Accepted Answer

To act as a gateway for communication between the instance and the local network. The MID Server acts as a bridge between the instance and the internal network for data collection.

Answer

To handle user authentication

Answer

To replace the need for firewalls

Answer

To store all network data

Question 6

When a MID Server is part of a cluster, what happens to the ECC queue items if one MID Server goes down?

Accepted Answer

The ECC queue items are re-assigned to other MID Servers in the cluster. If load balancing is configured, the other nodes in the cluster take over the work.

Answer

The ECC queue items are deleted

Answer

The jobs are marked as 'Failed'

Answer

The jobs stay in the queue until the failed server returns

Question 7

You need to set up a MID Server on Linux. What is the standard process for installing it?

Accepted Answer

Download, extract, and run the shell script. The standard method involves downloading the MID Server zip file, extracting it, and running the installer script.

Answer

Install via Update Set

Answer

Push an installer via the Discovery tool

Answer

Install via the ServiceNow GUI

Question 8

If a MID Server's 'Service' is running but the MID Server is 'Down' in the instance, what should you inspect?

Accepted Answer

The network connectivity and agent.config settings. If the service is up but the record is down, there is likely a network communication block or a configuration mismatch in agent.config.

Answer

The user's password in the instance

Answer

The MID Server's local disk space

Answer

The number of Discovery Schedules

Question 9

What happens if you have two MID Servers with the same name?

Accepted Answer

The MID Server will fail to register correctly. If two MID Servers are configured with the same name, the MID Server will fail to register correctly because the MID Server name is the unique identifier used by the instance to distinguish and manage MID Servers. Duplicate names cause registration conflicts and the MID Server cannot establish a valid identity with the instance.

Answer

They load balance automatically

Answer

The instance will merge them

Answer

Nothing, it is supported

Question 10

What is the purpose of the 'MID Server' log?

Accepted Answer

To store logs for troubleshooting the MID Server process. The MID Server log is specifically used to record events and errors related to the MID Server process itself. It is essential for troubleshooting issues such as connectivity, authentication, and job execution problems. The log is stored on the MID Server host and can be accessed for diagnostics.

Answer

To keep track of discovered CI data

Answer

To store credentials

Answer

To store user activity

Question 11

What is the effect of setting 'mid.log.level' to 'debug' in the agent.config file?

Accepted Answer

It provides more detailed troubleshooting information in the agent logs. Setting the log level to debug increases the granularity of the logs, useful for troubleshooting, but generates large files.

Answer

It increases the polling speed

Answer

It enables automatic error reporting

Answer

It forces the MID Server to re-validate

Question 12

Where are MID Server 'Capabilities' defined?

Accepted Answer

On the MID Server record. Capabilities are defined on the MID Server record under the Capabilities related list.

Answer

In the agent.config file

Answer

In the Discovery Schedule

Answer

In the System Properties

Question 13

If a MID Server is configured to use an encrypted credential but it is failing, what is the most likely cause?

Accepted Answer

The credential alias is not associated with the MID Server or its policy. Encrypted credentials in ServiceNow Discovery rely on credential aliases that must be explicitly associated with the MID Server or its MID Server policy. If the alias is not linked, the MID Server cannot decrypt or use the credential, causing authentication failures. This is the most common configuration oversight when encrypted credentials fail.

Answer

The MID Server is running on Windows

Answer

The MID Server is not in a cluster

Answer

The MID Server needs to be restarted

Question 14

What is the status of a newly installed MID Server that has not yet been validated?

Accepted Answer

Validation Required. New MID servers require validation by an admin before they are trusted to perform work.

Answer

Validated

Answer

Down

Answer

Up

Question 15

What does the 'Heartbeat' indicate in the MID Server record?

Accepted Answer

That the MID server is communicating with the instance. The heartbeat indicates that the instance and the MID server are actively talking to each other.

Answer

That the server is currently scanning

Answer

That the MID server is upgraded

Answer

That the MID server is in a cluster
