Question

You have been given an entry point for a load balancer and valid credentials, but during service mapping discovery, the target CI is not discovered. Which one of the following is the most likely cause of the problem?

a) Incorrect entry point
b) Invalid credentials
c) Firewall blocking discovery
d) Target CI is offline

Answer 1

The most likely cause of the problem is a firewall blocking discovery.

Step-by-step explanation:

The most likely cause of the problem is c) Firewall blocking discovery. When the firewall blocks the discovery process, it prevents the load balancer from accessing the target CI and therefore it cannot be discovered. This can happen if the firewall is configured to block certain ports or protocols that are necessary for the service mapping discovery to take place. The most likely cause of the problem is c) Firewall blocking discovery. When attempting service mapping discovery with a valid entry point (such as a load balancer) and credentials, the absence of the target Configuration Item (CI) suggests a communication issue. Firewalls can impede the discovery process by blocking the necessary data transmission between the discovery tool and the target CI. Ensuring that the firewall permits the required communication protocols is crucial. Incorrect entry points, invalid credentials, or the target CI being offline are plausible but less probable explanations, as they don't directly hinder the discovery process involving a valid entry point and credentials.
