300-415 · Question #436
Refer to the exhibit. Which command is needed to prevent end users from sending data traffic through CSR101?
The correct answer is A. omp no address-family ipv4. Removing the IPv4 address family from OMP stops the device from advertising and receiving IPv4 prefixes via OMP, effectively preventing data traffic forwarding for end users through CSR101.

Why each option
Removing the IPv4 address family from OMP stops the device from advertising and receiving IPv4 prefixes via OMP, effectively preventing data traffic forwarding for end users through CSR101.
The 'omp no address-family ipv4' command removes IPv4 prefix exchange from OMP on CSR101, meaning no IPv4 routes are advertised to or learned from the SD-WAN fabric, which prevents end-user data traffic from being steered through this device while leaving OMP sessions intact.
'omp no overlay-as' removes the overlay autonomous system number, which disrupts OMP session establishment entirely rather than selectively blocking data-plane route advertisements.
'omp no graceful-restart' only disables the graceful restart capability during OMP session failures and has no effect on normal data traffic forwarding.
'omp shutdown' tears down all OMP sessions completely, affecting both control and data plane operations rather than selectively preventing user traffic forwarding.
