  In this paper, we derive an exact black hole spacetime metric in the
Einstein-Hilbert-Bumblebee (EHB) gravity around global monopole field. We study
the horizon, temperature, and the photon sphere of the black hole. Using the
null geodesics equation, we obtain the shadow cast by the Schwarzschild-like
black hole with a topological defect in bumblebee gravity. Interestingly, the
radius of shadow of the black hole increases with increase in the global
monopole parameter. We also visualize the shadows and energy emission rates for
different values of parameters. Moreover, using the Gauss-Bonnet theorem, we
calculate the deflection angle in weak field limits and we discuss the
possibility of testing the effect of global monopole field and bumblebee field,
on a weak deflection angle. We find that the global monopole parameter and also
Lorentz symmetry breaking parameter has an increasing effect on the deflection
angle.
