SERVICENOW-CIS-DISCOVERY Mid Server Management Practice Test 2 — 15 Questions

Question 1

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 2

You have two MID Servers in a cluster. You want to ensure one takes over if the other fails. What setting must be configured?

Accepted Answer

Add both to a MID Server Cluster with 'Failover' behavior. Load balancing and failover are managed through the MID Server Cluster record.

Answer

Set the 'Cluster' property in the MID Server system properties

Answer

Configure the 'Primary' flag on the MID Server record

Answer

Set the 'Load Balance' flag on the MID Server record

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

An administrator needs to deploy a MID Server on a Windows host using a specific service account. Where should the credentials be stored to allow the MID Server to perform discovery?

Accepted Answer

In the ServiceNow Instance Credentials table. Credentials used by the MID Server for scanning are stored in the ServiceNow instance, not locally on the MID Server host.

Answer

In the agent.config file

Answer

In the wrapper.conf file

Answer

In the local Windows Credential Manager

Question 5

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. The MID Server Auto-Upgrade feature allows the instance to push updates to the agents automatically.

Answer

MID Server Update Sets

Answer

MID Server Cluster Overrides

Answer

Scheduled Jobs to restart services

Question 6

Which parameter in the 'agent.config' file specifies the interval the MID Server uses to check the ECC Queue?

Accepted Answer

mid.poll.time. The mid.poll.time parameter dictates how frequently the MID Server polls the instance for new tasks.

Answer

mid.heartbeat.frequency

Answer

mid.task.interval

Answer

mid.ecc.timeout

Question 7

Which user role is required to manage MID Server records?

Accepted Answer

mid_server_admin. The mid_server_admin role provides the necessary permissions to configure and manage MID Servers.

Answer

discovery_admin

Answer

admin

Answer

itil

Question 8

How do you verify if a MID Server is using the correct Java version?

Accepted Answer

Check the 'Java version' field on the MID Server record. The MID Server record provides a 'Java version' field or the wrapper log shows the environment details.

Answer

Check the Discovery Schedule

Answer

Check the MID Server System Properties

Answer

Check the ECC Queue Input

Question 9

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 10

A MID Server is configured to scan a network segment but the scan fails with an 'Access Denied' error. Where should you look to ensure the MID Server is using the correct credentials?

Accepted Answer

Discovery Logs. The Discovery Logs provide the specific execution details, including which credentials were tried and rejected.

Answer

Service Mapping Logs

Answer

MID Server Logs

Answer

Credential Store

Question 11

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 12

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 13

Where do you go to see a list of all available MID Servers in your instance?

Accepted Answer

MID Servers > Servers. The MID Server list view is available under the MID Server module.

Answer

ECC Queue

Answer

System Properties

Answer

Discovery Dashboard

Question 14

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 15

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

Accepted Answer

The MID Server will fail to register correctly. Naming collisions in MID Servers cause registration failures or erratic behavior as they attempt to update the same record.

Answer

They load balance automatically

Answer

The instance will merge them

Answer

Nothing, it is supported
