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

Question 1

If a MID Server is behind a load balancer, what configuration might be required?

Accepted Answer

Configure the MID Server to trust the Load Balancer's certificate. The load balancer may terminate SSL or require specific headers, which must be accounted for in the MID Server configuration.

Answer

Reduce the polling time

Answer

Disable the MID Server firewall

Answer

Set the MID Server to 'Internal' mode

Question 2

Which platform can a MID Server be installed on?

Accepted Answer

Windows, Linux, and macOS. ServiceNow supports running MID Servers on Windows, Linux, and other Java-supported OS environments.

Answer

Android

Answer

Only Windows

Answer

Only Linux

Question 3

What module allows you to monitor the status of all MID Servers at a glance?

Accepted Answer

MID Servers > Servers (List view). The MID Server dashboard or list view provides a quick overview of status.

Answer

System Logs

Answer

ECC Queue

Answer

Discovery Dashboard

Question 4

Which TWO file types are typically located in the MID Server 'agent' directory?

Accepted Answer

Configuration files (e.g., agent.config). The agent directory contains configuration files and the binary scripts for starting the service.

Answer

User session tokens

Answer

Discovery results

Answer

Database files

Question 5

Which THREE logs should you investigate when troubleshooting a failing discovery task?

Accepted Answer

Discovery log. The Discovery log (B) is the primary record of the discovery process itself, capturing scan scheduling, probe execution, classification, and errors specific to the failing discovery task. The Agent log (C) is relevant because discovery in many platforms is performed by an agent or mid-server process, and its log records agent-side failures such as connection issues, credential problems, or probe execution errors that would cause discovery to fail. The Wrapper log (E) records the startup, shutdown, and execution of the underlying service/process wrapper that launches discovery and related components, so it reveals crashes, JVM or process-level failures, and restart loops affecting the discovery task. The System log (A) and Event log (D) are general OS-level logs that may show unrelated system activity and are not the targeted logs used to diagnose a failing discovery task, so they are not among the three to investigate.

Answer

System log

Answer

Event log

Question 6

Which THREE parameters are commonly found in the agent.config file?

Accepted Answer

mid.proxy.host. In the agent.config file, mid.proxy.host (C) is correct because it specifies the proxy host used when the agent must route outbound communication through an HTTP proxy. mid.thread.max (D) is correct because it defines the maximum number of worker threads the agent can use for processing tasks. mid.instance.uri (E) is correct because it identifies the URI of the instance the agent connects to. The unmarked options mid.db.connection (A) and mid.user.password (B) do not belong because database connection strings and user passwords are not standard agent.config parameters in this context.

Answer

mid.db.connection

Answer

mid.user.password

Question 7

Which THREE statuses can a MID Server be in?

Accepted Answer

Up. In ServiceNow, a MID Server's status field reflects its operational state as seen by the instance, and the three valid statuses are Up, Down, and Validation Required. Option A (Up) is correct because it indicates the MID Server is running, connected, and actively able to execute probes and jobs for the instance. Option D (Validation Required) is correct because it appears when the MID Server's configuration or credentials must be validated before it can be trusted to run work, such as after installation or a configuration change. Option E (Down) is correct because it indicates the MID Server is not currently connected or reachable by the instance, so it cannot process any jobs. Option B (Restarting) is not a status value — restarting is an action performed on a MID Server, not a reported state. Option C (Pending Upgrade) is not a MID Server status; upgrades are handled through the MID Server upgrade process and do not appear as a status in this list.

Answer

Restarting

Answer

Pending Upgrade

Question 8

Which THREE things occur during the MID Server startup process?

Accepted Answer

Checking for version updates. The startup process involves loading configurations, checking for updates, and establishing an initial heartbeat.

Answer

Scanning the entire network

Answer

Creating new user accounts

Question 9

You are configuring a MID Server Cluster for high availability. What determines which MID Server in the cluster processes a specific task?

Accepted Answer

The 'Load Balancing' policy selected on the Cluster record. When a MID Server Cluster is configured, the Load Balancing policy on the Cluster record determines how tasks are distributed among member MID Servers. The policy options (such as Round Robin, Least Busy, or Failover) dictate which MID Server picks up a given ECC queue task, providing both distribution and high availability.

Answer

The 'ECC Queue' record priority

Answer

The 'Performance Metric' score calculated by the instance

Answer

The 'Cluster Priority' field on the MID Server record

Question 10

A MID Server is configured to use an encrypted proxy for internet access. Where must this configuration be defined?

Accepted Answer

The config.xml file on the host machine. Proxy settings for a MID Server — including encrypted proxy authentication — are defined in the config.xml file on the MID Server host itself, not in the ServiceNow instance. The MID Server reads config.xml at startup to know how to reach the instance through the proxy. This is why the correct answer is the host-side file rather than any ServiceNow table or module.

Answer

The 'MID Server Proxy' table in ServiceNow

Answer

The 'Discovery Credential' record

Answer

The 'MID Server Properties' module

Question 11

You are decommissioning a MID Server. What is the best practice to ensure no data is lost during the transition?

Accepted Answer

Set the status to 'Down' and wait for active tasks to finish. Setting the status to 'Down' prevents new tasks from being assigned while allowing existing tasks to complete.

Answer

Delete the MID Server record from the ServiceNow instance

Answer

Stop the MID Server service on the host only

Answer

Clear the 'Capabilities' field

Question 12

Which THREE pieces of information are displayed in the MID Server Dashboard?

Accepted Answer

ECC Queue processing time. The MID Server Dashboard in ServiceNow displays operational health and performance metrics for MID Servers. Option A (ECC Queue processing time) is correct because the dashboard shows how long the MID Server takes to process ECC queue entries, which is a key performance indicator. Option B (Disk space usage) is correct because the dashboard includes disk space metrics to help monitor MID Server host resource availability. Option D (MID Server status (Up/Down)) is correct because the dashboard prominently shows whether each MID Server is up or down, which is essential for monitoring connectivity. Option C is not correct because the dashboard never displays the MID Server User password, as credentials are stored securely and not exposed in dashboards. Option E is not correct because the OS version of target devices being scanned is discovery data stored on CI records, not a MID Server Dashboard metric.

Answer

The password used for the MID Server User

Answer

The OS version of the target devices being scanned

Question 13

Which TWO criteria must be met for a MID Server to be eligible to join a MID Server Cluster?

Accepted Answer

The MID Server must be in the 'Validated' status. Option A is correct because a MID Server must have a status of 'Validated' before it can be added to a cluster; only validated MID Servers are considered eligible to participate in cluster operations. Option B is correct because all members of a MID Server Cluster must be connected to the same ServiceNow instance, since the cluster coordinates work distribution through that instance. Option C is incorrect because cluster members must have unique names, not identical names, to be individually identified. Option D is incorrect because sharing the same MID Server User is not a cluster eligibility requirement, though the user must have appropriate roles. Option E is incorrect because cluster members can run on different physical hosts; they are not required to be co-located.

Answer

The MID Server must have the exact same 'Name' as the other cluster members

Answer

The MID Server must share the same 'MID Server User'

Answer

The MID Server must be installed on the same physical host

Question 14

Which THREE of the following are valid methods for upgrading MID Servers?

Accepted Answer

Running the MID Server installer locally on the host. Option A is correct because running the MID Server installer locally on the host is a supported manual upgrade method: you download the new MID Server package from the instance and execute the installer, which replaces the binaries and restarts the service. Option B is correct because MID Server Auto-Upgrade properties (such as mid.auto_upgrade.enabled and the associated version/upgrade settings) let the instance automatically push and apply the new MID Server build to eligible MID Servers. Option E is correct because the 'Upgrade' related link on the MID Server record triggers the instance to send the upgrade command/package to that MID Server, initiating the supported upgrade workflow. Option C is not valid because manually running a PowerShell script to force a version change is not a supported upgrade mechanism and can corrupt the MID Server installation. Option D is not valid because deleting and recreating the MID Server record does not upgrade the installed MID Server software; it only affects the instance-side record and configuration.

Answer

Running a PowerShell script on the host to force a version change

Answer

Deleting and recreating the MID Server record

Question 15

You are implementing Discovery for a large enterprise with multiple network segments. To optimize performance, you want to deploy several MID Servers, each dedicated to a specific IP range. Which MID Server configuration property should you use to restrict which IP addresses a MID Server can discover?

Accepted Answer

mid.network.ip_ranges. The MID Server property 'mid.network.ip_ranges' allows administrators to specify which IP ranges a MID Server can discover. By setting this property, you ensure that each MID Server only scans its assigned network segments, which is essential for load distribution and avoiding duplicate discovery. This property is commonly used in large, segmented environments.

Answer

mid.network.scope

Answer

mid.network.ip_range

Answer

mid.discovery.ip_scope
