Question 1

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

Answer

The user's password in the instance

Answer

The MID Server's local disk space

Answer

The number of Discovery Schedules

Question 2

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 3

Which TWO factors are used to configure a MID Server Cluster?

Accepted Answer

Member MID Servers. Clusters require a defined behavior (e.g., failover) and at least one member MID server.

Answer

Proxy settings

Answer

Network firewall ports

Answer

Discovery Schedule

Question 4

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 5

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

Question 6

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 7

How can you prevent a specific MID Server from being used for Discovery?

Accepted Answer

Remove the 'Discovery' capability from the MID Server record. Removing the 'Discovery' capability effectively prevents the MID Server from being assigned discovery jobs.

Answer

Delete the discovery schedule

Answer

Pause the MID Server

Answer

Change the MID Server status to 'Down'

Question 8

A MID Server is installed behind a proxy. Which file must be modified to ensure the MID Server can reach the instance?

Accepted Answer

agent.config. The agent/conf/agent.config file contains the network proxy settings required for the MID Server to tunnel traffic to the instance.

Answer

proxy.xml

Answer

mid_server.properties

Answer

wrapper.conf

Question 9

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 10

When configuring a connection in a pattern, which attribute is used to define the entry point, such as an IP address or URL?

Accepted Answer

Connection Definition. The 'Connection' section of a pattern is where you define the entry points (host, port, URL) that the pattern will connect to.

Answer

Identification Rule

Answer

Discovery Schedule

Answer

Target Identification

Question 11

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.
