A.Implement a firewall filter on the VLAN v50, blocking traffic to/from 2001:db8:0000:50::10.

B.Implement persistent MAC learning to ensure that 2001:db8:0000:50::10 is allocated properly.

C.Implement DHCP snooping on VLAN v50 to ensure that 2001:db8:0000:50::10 is allocated properly.

D.Implement a firewall filter on the IRB interface for VLAN v50, blocking traffic to/from 2001:db8:0000:50::10.

A.MACsec

B.dynamic ARP inspection

C.IP source guard

D.persistent MAC learning

A.Keepalives must be used on stateless tunneling protocols.

B.BGP must be used on intermediate devices.

C.Tunnel endpoints must have a route that directs traffic into the tunnel.

D.Tunnel endpoints must have a valid route to the remote endpoint.

E.All intermediary devices must have a route to the tunnel endpoints.

A.An aggregate route always shows as active in the routing table.

B.An aggregate route has a default next hop of an IP address.

C.An active route can contribute only to a single aggregate route.

D.Only one aggregate route can be configured for each destination prefix.

A.You need to modify the martian table with a 191.255.0.0/16 accept statement

B.The default OSPF export policies advertise nothing, so you need to apply export policy

C.The default OSPF import policy rejects all OSPF routes, so you need to apply import policy

D.You need to enable OSPF on the lo0 interface to provide a route to the RID of each router in the network
