We study resonance behavior of a two-dimensional fully frustrated Josephson-junction array driven by high alternating currents. The signal-to-noise ratio (SNR) is examined as the frequency of the driving current is varied; revealed is a certain frequency range where the SNR is enhanced. Such resonance behavior is explained by considering the dynamic order parameter at zero temperature. We also compute the work, which corresponds to the Ohmic dissipation of the energy due to external currents, and discuss its possibility as a measure of stochastic resonance.
