SERVICENOW-CIS-DISCOVERY Mid Server Management Practice Test 3 — 15 Questions

Question 1

During a Discovery implementation, you need to ensure that a MID Server can communicate with the ServiceNow instance over HTTPS. The MID Server is installed on a Windows server in a secure subnet that only allows outbound traffic on port 443. Which configuration must be validated on the MID Server to ensure successful outbound communication?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The MID Server's config.xml file must contain the correct instance URL and MID Server user credentials.. The MID Server uses the instance URL and credentials specified in its config.xml file to establish an outbound HTTPS connection. Even with port 443 open, incorrect URL or credentials will prevent communication. Other options are either unnecessary or relate to different aspects of MID Server operation.

Answer

The MID Server must have the 'mid.server.port' property set to 443 in the system properties.

Answer

The MID Server service must be running under a domain account with Kerberos delegation enabled.

Answer

The MID Server must be configured with a static IP address and registered in DNS.

Question 2

A discovery administrator needs to ensure that a new MID Server, installed in a DMZ network segment, can only be used for discovery tasks and not for orchestration or integration activities. The MID Server has been validated and is currently in 'Up' state. Where should the administrator configure this restriction?

Accepted Answer

On the MID Server record, set the 'Capabilities' field to 'Discovery' only.. The Capabilities field on the MID Server record is the authoritative way to control which job types a MID Server can execute. Setting it to only 'Discovery' ensures that the instance will not assign orchestration, integration, or other non-discovery jobs to that MID Server. This is essential for security and network segmentation, especially in DMZ environments where the MID Server should have limited roles.

Answer

Use a MID Server selection rule to filter out non-discovery jobs for this MID Server.

Answer

Create a new MID Server cluster and assign only discovery jobs to that cluster.

Answer

In the MID Server properties, set 'mid.server.capabilities' to 'discovery'.

Question 3

An administrator opens a MID Server record and needs to force the instance to re-evaluate whether the MID Server is still reachable and healthy without waiting for the normal heartbeat interval. Which related link on the MID Server record performs this action?

Accepted Answer

Refresh Status. Refresh Status is the related link that prompts the instance to re-check the MID Server's health and update its status without waiting for the periodic heartbeat. Restart MID Server disrupts the running process, Test MID Server focuses on authentication and connectivity testing, and Validate is used during initial configuration. Only Refresh Status provides the immediate, non-disruptive status re-evaluation the administrator needs.

Answer

Validate

Answer

Test MID Server

Answer

Restart MID Server

Question 4

A MID Server is being configured to connect to a ServiceNow instance that uses a proxy server for all outbound HTTP/HTTPS traffic. The MID Server must be able to reach the instance through the proxy. Which two configuration parameters must be set in the MID Server's config.xml file? (Choose two.)

Accepted Answer

mid.proxy.host. To route MID Server traffic through a proxy, the two essential parameters in config.xml are mid.proxy.use_proxy (set to true) and mid.proxy.host (the proxy's address). These enable the MID Server to direct all outbound connections to the proxy. Additional parameters like username and password are only needed if the proxy requires authentication, which is not specified in the scenario.

Answer

mid.proxy.port

Answer

mid.proxy.password

Answer

mid.proxy.username

Question 5

You are troubleshooting a MID Server that is unable to process discovery tasks. After reviewing the MID Server logs, you suspect that the issue is related to the MID Server's user account permissions. Which two roles must be assigned to the MID Server user to allow it to perform discovery? (Choose two.)

Accepted Answer

discovery. The MID Server user must have the 'mid_server' role to interact with the instance and the 'discovery' role to perform Discovery tasks. These two roles provide the necessary permissions without granting excessive privileges. Other roles like 'admin' or 'discovery_admin' are not required and should be avoided for security reasons.

Answer

admin

Answer

discovery_admin

Answer

itil

Question 6

A MID Server is deployed in a network that uses a firewall that only allows outbound connections on port 443. The MID Server must communicate with the ServiceNow instance. Which configuration ensures that the MID Server uses the correct port and protocol?

Accepted Answer

Set the MID Server's 'URL' property to the instance URL with 'https://' and ensure the port is 443.. The MID Server communicates with the ServiceNow instance using the URL defined in the mid.instance.url property. This URL must include 'https://' to use HTTPS, which by default uses port 443. If the instance is configured to use a non-standard port, it must be specified in the URL (e.g., 'https://instance.service-now.com:8443'). In this scenario, the firewall allows outbound 443, so setting the URL to 'https://' ensures the MID Server uses the correct port and protocol.

Answer

Set the MID Server's 'Port' property to 443 and 'Protocol' to 'http'.

Answer

Configure the MID Server to use a proxy that forwards traffic to port 443.

Answer

Set the MID Server's 'mid.instance.port' property to 443 and 'mid.instance.protocol' to 'https'.

Question 7

You notice a MID Server has the status 'Down' in the ServiceNow instance, but the service is running on the host. What is the first step to troubleshoot?

Accepted Answer

Check the agent log file (agent/logs/agent0.log.0) for connection errors.. Checking the agent log is the standard first step for identifying why the MID Server is failing to heartbeat or authenticate.

Answer

Restart the ServiceNow instance.

Answer

Update the MID Server version in the MID Server record.

Answer

Reinstall the MID Server.

Question 8

A customer needs to restrict a MID Server to only perform discovery on specific IP ranges. Which mechanism should be used to accomplish this?

Accepted Answer

Define 'MID Server IP Ranges' related list on the MID Server record.. MID Server IP Ranges are used to define the boundaries of what a specific MID Server is allowed to scan.

Answer

Set the 'Scan Limitation' property on the MID Server configuration file.

Answer

Use the 'Discovery Schedule' Exclude IP list only.

Answer

Apply a Business Rule to the ECC Queue.

Question 9

Where do you define the MID Server capabilities that allow it to perform specific tasks like Orchestration or Discovery?

Accepted Answer

In the MID Server record's 'Capabilities' related list.. MID Server Capabilities are managed via the 'Capabilities' related list on the MID Server record.

Answer

In the 'Discovery Definition' module.

Answer

In the 'MID Server Properties' module.

Answer

In the config.xml file.

Question 10

You are deploying a MID Server behind a strict firewall. To ensure the MID Server can communicate with the ServiceNow instance without opening unsolicited inbound ports, which configuration is required?

Accepted Answer

Ensure the firewall allows outbound HTTPS traffic from the MID Server to the instance.. MID Servers communicate via outbound HTTPS (443) requests to the instance, meaning no inbound ports need to be opened on the firewall.

Answer

Set the MID Server listener port to 8443 on the local firewall.

Answer

Configure the instance to use an inbound static IP for the MID Server.

Answer

Enable the 'Inbound Proxy' setting in the MID Server configuration file.

Question 11

A MID Server Cluster is configured with two nodes. One node goes down. How does the MID Server Cluster handle the failover?

Accepted Answer

The cluster automatically shifts the workload to the healthy node in the cluster.. MID Server clusters automatically distribute work, and if one node fails, the cluster manager ensures tasks are re-queued or picked up by the remaining node.

Answer

The cluster requires a manual restart of the remaining node to resume work.

Answer

The instance marks the MID Server as 'Down' and stops all processing for the entire cluster.

Answer

All tasks are automatically lost and must be manually re-run.

Question 12

When using multiple MID Servers for load balancing, what is the best way to group them?

Accepted Answer

Create a MID Server Cluster.. MID Server Clusters allow you to group MID Servers for load balancing and failover.

Answer

Use the 'MID Load Balancer' application.

Answer

Update the config.xml on each server to point to the same instance node.

Answer

Assign them the same IP range.

Question 13

Which TWO of the following are true regarding MID Server startup parameters in the config.xml?

Accepted Answer

They contain the instance URL and the MID server user credentials.. Option B is correct because config.xml stores the essential connection parameters the MID Server needs, including the instance URL (e.g., https://<instance>.service-now.com) and the MID Server user credentials used to authenticate to the instance. Option D is correct because these startup parameters are precisely what the MID Server reads on initial startup to establish its connection and register with the instance before any instance-side properties can be applied. Option A is incorrect because config.xml is a local file on the MID Server host and is not editable through the ServiceNow UI. Option C is incorrect because instance-side MID Server record properties take precedence over the local config.xml values once the MID Server is connected, not the other way around. Option E is incorrect because config.xml is not automatically synced with instance properties on an hourly schedule; it is a local bootstrap configuration file.

Answer

The file can be edited via the ServiceNow UI.

Answer

These settings override any properties set in the MID Server record in the instance.

Answer

They are automatically synced with the instance properties every hour.

Question 14

What happens to the ECC Queue if the MID Server is unable to connect to the ServiceNow instance?

Accepted Answer

The records stay in the 'ready' state until the MID Server reconnects.. If the MID is down, the ECC Queue records remain in the 'ready' state on the instance and wait until the MID reconnects to process them.

Answer

The instance marks the records as 'processed'.

Answer

The records are automatically moved to the error state.

Answer

The records are automatically deleted.

Question 15

A MID Server is currently in the 'Down' state. Which module should an administrator check first to identify the specific connectivity error?

Accepted Answer

ECC Queue. The ECC Queue contains status messages and error logs that identify why a MID Server cannot communicate with the instance.

Answer

Discovery Dashboard

Answer

Discovery Logs

Answer

MID Server Properties
