Refer to the exhibit. An engineer must configure router R1 to allow only NETCONF connections from the management VLAN. Which command completes this configuration?
A.
R1(config-if)# ip access-group netconfacl in
B.
R1(config)# netconf-yang ipv4 access-list name netconfacl
C.
R1(config)#ip http secure-server R1(config)# ip http accounting commands 12 default
It's B see https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/1612/b_1612_programmability_cg/netconf_and_restconf_service_level_acls.pdf
In a typical scenario where the goal is to restrict NETCONF connections from a specific VLAN (such as the management VLAN), using an access control list (ACL) applied outbound on the interface connected to that VLAN is a common approach.

Device(config-std-nacl)# exit
Device(config)# netconf-yang ssh ipv4 access-list name acl1_permit
