Narrative:
We were level at 11000 ft and given known VFR traffic at 10500. TCASII was showing the traffic and at 3 mi gave us an RA to climb and monitor vertical speed. We tried to visually pick up the traffic but couldn't so a climb was initiated and ATC was advised. We climbed to 11500 and after clear of traffic returned to 11000. ATC later questioned our action, however, without visual contact, a climb must be initiated.

Title: FLC OF AN MLG ACR ACFT CLBED ABOVE ASSIGNED ALT IN RESPONSE TO A TCASII RA.
Narrative: WE WERE LEVEL AT 11000 FT AND GIVEN KNOWN VFR TFC AT 10500. TCASII WAS SHOWING THE TFC AND AT 3 MI GAVE US AN RA TO CLB AND MONITOR VERT SPD. WE TRIED TO VISUALLY PICK UP THE TFC BUT COULDN'T SO A CLB WAS INITIATED AND ATC WAS ADVISED. WE CLBED TO 11500 AND AFTER CLR OF TFC RETURNED TO 11000. ATC LATER QUESTIONED OUR ACTION, HOWEVER, WITHOUT VISUAL CONTACT, A CLB MUST BE INITIATED.
