Question 170
A switch team takes firmware backups but no configuration snapshot before a planned major change. Which immediate engineering change most directly addresses this issue?
Explanation
Correct Answer
The underlying issue is that a software image alone does not reconstruct the previous running configuration. This intervention addresses that cause directly. A useful result to confirm is: a staged rollback restores the intended switch configuration and services.
Incorrect Answers
This is suited to a different condition, such as when a monitoring API integration stops receiving data after a credential rotation despite healthy switch and WAN links. The reported fault instead arises because a software image alone does not reconstruct the previous running configuration.
This is suited to a different condition, such as when UXI sensors show failed cloud-application transactions but the WLAN dashboard reports healthy client associations. The reported fault instead arises because a software image alone does not reconstruct the previous running configuration.
This is suited to a different condition, such as when a monitoring dashboard hides real device outages because its poller assumes success on missing SNMP responses. The reported fault instead arises because a software image alone does not reconstruct the previous running configuration.
