SERVICENOW-CIS-DISCOVERY Practice Test 21 — 15 Questions

Question 1

If you have a pattern that identifies a CI but fails to update its attribute, which log should you check first?

Accepted Answer

Discovery Pattern Log. The Discovery Pattern Log provides the most detail regarding step execution and attribute assignment failures.

Answer

System Log

Answer

CMDB Health Dashboard

Answer

MID Server Log

Answer

Node Log

Question 2

Which TWO of the following are valid ways to debug a pattern?

Accepted Answer

Review the 'Pattern Log' in the Discovery Status. You can use the debugger with saved status data or preview the output in the step.

Answer

Restart the instance

Answer

Modify the MID Server source code

Answer

Run the pattern from the command line

Question 3

Which TWO of the following steps are required when adding a new CI relationship in a pattern?

Accepted Answer

Add 'Define Relationship' step. You need to identify the related CI and then define the relationship between them.

Answer

Add 'Modify Attribute' step

Answer

Add 'Validate' step

Answer

Add 'Delete CI' step

Question 4

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 5

Which THREE actions occur when a pattern is published?

Accepted Answer

The pattern moves from 'Draft' to 'Active'. Publication makes the pattern active, allows it to be used by discovery, and saves a version.

Answer

The MID server is restarted

Answer

The pattern is deleted

Question 6

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 7

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 8

Which THREE common challenges arise when using Regex to extract data from command outputs in patterns?

Accepted Answer

Potential for catastrophic backtracking on large strings. Regex is sensitive to output changes, can be complex to maintain, and might cause performance issues if not optimized.

Answer

Regex does not support capture groups

Answer

Regex is automatically converted to JSON

Question 9

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 10

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 11

A MID Server is connected to the instance but 'Discovery' is not working. What is the most likely cause related to the MID Server configuration?

Accepted Answer

The MID Server lacks the 'Discovery' capability. The MID Server might not have the 'Discovery' capability assigned to it.

Answer

The MID Server is not validated

Answer

The MID Server is too old

Answer

The proxy is down

Question 12

Which THREE pieces of information are required for a MID Server to communicate with the ServiceNow instance?

Accepted Answer

Instance URL. Connectivity requires a valid URL, authentication (as configured via the MID server record), and the ability to reach the instance via proxy/firewall.

Answer

Admin password for the host

Answer

Database credentials

Question 13

When a pattern step executes an external script (e.g., Python), how can you ensure the pattern waits for the script to finish before proceeding to the next step?

Accepted Answer

The pattern automatically waits for the step process to return. ServiceNow patterns are synchronous by default; the pattern engine waits for each step to return a status (Success/Failure) before moving to the next step.

Answer

Use an asynchronous flag in the script

Answer

Configure the MID Server to process sequentially

Answer

Add a Wait step

Question 14

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 15

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
