Which task would be the responsibility of a level 2 technician?

When a company has a Tier hierarchy [ie. Tier 1, Tier 2, Tier3], a second level tier or "level 2 technician" would be responsible for specialization. For instance, if we were to compare and contrast your question to the responsibility of a Computer Technician the following scenario would be true: A primary response or first level technician would gather the information and try to solve the incident. If the incident cannot be solved because it requires a level 2 technician (ie. special network access), one would need to move the incident to a level 2 technician. In this case, the responsibility of the level 2 technician would be to complete the work assessed and assist the client or customer with the incident using their specialization.
