Engineer Briefing

A real network engineer is not measured by how well they configure devices.

They are measured by how well they respond when things break.

In production environments, problems are rarely simple.

A user may report:

"The Internet is not working."

But the real cause could be:

• A failed interface.
• A routing issue.
• A VLAN problem.
• A DNS failure.
• A security policy.
• A misconfiguration.

Engineers must investigate using evidence.
