Refer to the exhibit. Based on the provided Flex-spoke IKEv2 authorization policy configuration, which command is required to configure route set remote ipv4 192.168.100.0 255.255.255.0 on the spoke…

Adding aaa authorization group cert list default default to the spoke IKEv2 profile enables certificate-based group authorization lookup but does not itself inject a route - it only determines which authorization policy is applied.

Adding a route set command for 192.168.200.0/24 to the hub authorization policy would install a route toward the hub prefix on the spoke, which is the opposite of what is required and addresses a different subnet.

Adding the aaa authorization group cert list command to the hub IKEv2 profile controls how the hub itself is authorized, not how routes for the spoke subnet are pushed to the hub.

The route set remote ipv4 command inside an IKEv2 authorization policy instructs the router to install a static route toward the remote peer for the specified prefix upon tunnel establishment. Because 192.168.100.0/24 is the spoke's local subnet that should be reachable via the spoke, this command must reside in the spoke's own authorization policy so the hub installs the route pointing toward that spoke when it authenticates.
