Your trainer wants you to use your skills to prove that you are ready to face the many dangers that exist in the world.
'Ah, I am glad to see you, friend! I chose the path of the Warden long ago, and perhaps -- if you are willing to listen -- I can help a young one like yourself.
'A Warden is a master of sword, spear, shield, and javelin. He is also an excellent study of his enemies and will learn how an enemy can be toppled with the right combination of blows or how to strengthen his own heart for the battles to come. And battles will be plentiful, for a Warden seeks to defend those who cannot defend themselves by drawing the enemy's eye.
'Use the skill Defensive Strike on the training-dummy nearby.'
HINT:
Wardens use combinations of their basic skills such as Quick Thrust and Shield-bash to build more powerful Gambit attacks. To use your Defensive Strike skill, attack a Training-Dummy with your Shield-bash ability twice. This should cause your Gambit Default skill to change into your Defensive Strike skill. Use your Defensive Strike ability to strike a Training-Dummy.

The Warden Trainer is in Archet, in the training grounds.
Now that you have successfully used Defensive Strike, you should return to your trainer and tell him of your success.
