We study the implication of the LHC Higgs search results on the Type II TwoHiggs-Doublet Model. In particular, we explore the scenarios in which theobserved 126 GeV Higgs signal is interpreted as either the light CP-even Higgs$h^0$ or the heavy CP-even Higgs $H^0$. Imposing both theoretical andexperimental constraints, we analyze the surviving parameter regions in $m_H$($m_h$), $m_A$, $m_{H^\pm}$, $\tan\beta$ and $\sin(\beta - \alpha)$. We furtheridentify the regions that could accommodate a 126 GeV Higgs with cross sectionsconsistent with the observed Higgs signal. We find that in the $h^0$-126 case,we are restricted to narrow regions of $\sin(\beta-\alpha) \approx \pm 1$ with$\tan\beta$ up to 4, or an extended region with $0.55 < \sin(\beta-\alpha) <0.9$ and $1.5 < \tan\beta < 4$. The values of $m_H$, $m_A$ and $m_{H^\pm}$,however, are relatively unconstrained. In the $H^0$-126 case, we are restrictedto a narrow region of $\sin(\beta-\alpha) \sim 0$ with $\tan\beta$ up to about8, or an extended region of $\sin(\beta-\alpha) $ between $-0.8$ to $-0.05$,with $\tan\beta$ extended to 30 or higher. $m_A$ and $m_{H^\pm}$ are nearlydegenerate due to $\Delta\rho$ constraints. Imposing flavor constraints shrinksthe surviving parameter space significantly for the $H^0$-126 case, limiting$\tan\beta \lesssim 10$, but has little effect in the $h^0$-126 case. We alsoinvestigate the correlation between $\gamma\gamma$, $VV$ and $bb/\tau\tau$channels. $\gamma\gamma$ and $VV$ channels are most likely to be highlycorrelated with $\gamma\gamma:VV \sim 1$ for the normalized cross sections.
