The correct get-config reply is the one that shows OSPF process ID 200 and the network 172.16.10.128/26 assigned to Area 0 in the same YANG model hierarchy that was used for configuration. In model-driven configuration, verification is not based on visual similarity to CLI output; it is based on whether the operational or running datastore contains the intended structured objects at the correct schema paths. For IOS XE native OSPF configuration, the process identifier, network statement, wildcard or prefix representation, and area association must be represented exactly as the model requires. A /26 network beginning at 172.16.10.128 covers addresses 172.16.10.128 through 172.16.10.191, so replies showing a different base network, wrong process ID, wrong area, or invalid mask cannot verify the design. Option A is the matching reply. The professional validation workflow is to send the configuration, read back the intended datastore using get-config, and confirm the model fields rather than relying only on CLI screen output.
