  In this paper, the Dvali-Gabadadze-Porrati (DGP) brane model is confronted by
current cosmic observational data sets from geometrical and dynamical
perspectives. On the geometrical side, the recent released Union2 $557$ of type
Ia supernovae (SN Ia), the baryon acoustic oscillation (BAO) from Sloan Digital
Sky Survey and the Two Degree Galaxy Redshift Survey (transverse and radial to
line-of-sight data points), the cosmic microwave background (CMB) measurement
given by the seven-year Wilkinson Microwave Anisotropy Probe observations
(shift parameters $R$, $l_a(z_\ast)$ and redshift at the last scatter surface
$z_\ast$), ages of high redshifts galaxies, i.e. the lookback time (LT) and the
high redshift Gamma Ray Bursts (GRBs) are used. On the dynamical side, data
points about the growth function (GF) of matter linear perturbations are used.
Using the same data sets combination, we also constrain the flat $\Lambda$CDM
model as a comparison. The results show that current geometrical and dynamical
observational data sets much favor flat $\Lambda$CDM model and the departure
from it is above $4\sigma$($6\sigma$) for spatially flat DGP model
with(without) SN systematic errors. The consistence of growth function data
points is checked in terms of relative departure of redshift-distance relation.
