I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This depends a lot on the company landscape.
Basically I would say that on L1 there won't be any DBA. It's a first line of support so they only follow a script with questions to get more information and depending on the answer they can try to solve the issue or escalate to L2.
L2 in some companies also don't have DBA's but in some there are.
L3 is where the DBA's fits. If in L2 there are also DBA's then in L3 should be only for Senior DBA's / Specialists.

So, I would say these are the more common tasks for each level:

1.

Collecting information / Start, Cancel and Restart jobs / Start stopped services / Execute backups

2.

Collecting information / Start, Cancel and Restart jobs / Start stopped services / Execute backups and restores / Patch management / Kill processes

3.

Collecting information / Start, Cancel and Restart jobs / Start stopped services / Execute backups and restores / Patch management / Kill processes / Performance & Tuning / SQL Server install & uninstall / SQL Server configuration / Database upgrades & migration / Solve other incidents
And much more for L3 for sure but can't remember all now.

Here is a full list for an Oracle DBA which will be more or less in line with what any DBA will do for any DB. Just tweak the Oracle word with the type of DB that is required to support...
