The electronic configuration that corresponds to an inert gas is

The element contain $1{\text{s}}^{2}2{\text{s}}^{2}2{\text{p}}^6$  electronic configuration (Ne) is completely filled with eight electrons in its outer most shell. Generally inert gas elements have 8 electrons in its outer most shell.  So,  $1{\text{s}}^{2}2{\text{s}}^{2}2{\text{p}}^6$ is a inert gas element electronic configuration.
