A network technician receives a ticket stating that remote users at a new satellite office cannot reach the company's internal intranet application. The technician interviews affected users, duplicates the failure on a test host, and receives a 'Destination Host Unreachable' message. The technician then formulates a hypothesis that an incorrect VLAN tagging policy on the WAN router interface is stripping traffic. To verify this, the technician runs a packet capture on the router interface and confirms that frames are arriving with an unexpected VLAN ID tag, validating the root cause. According to the CompTIA troubleshooting methodology, which of the following steps should the technician execute NEXT?
- Establish a plan of action to resolve the issue and identify potential effects.Answer
- BPerform complete end-to-end connectivity tests across all satellite office workstations.
- CUpdate the network infrastructure ticketing system with the final root cause analysis and resolution steps.
- DQuestion the obvious by verifying physical Layer 1 cable continuity and link status indicators on the switch.
Answer
Establish a plan of action to resolve the issue and identify potential effects.
The scenario describes a technician who has already identified the problem, established a theory of probable cause, and tested the theory to confirm the root cause via packet capture analysis. According to the CompTIA troubleshooting methodology, once the theory is confirmed, the immediate next step is to establish a plan of action to resolve the problem and identify potential effects.
