The given Answer is wrong. It deny the route with tag 200 but this is the route R1 have to redistribute. The correct answer should be: 

R1(config)#route-map CCNP permit 10
R1(config-route-map)#match tag 200
R1(config-route-map)#exit
R1(config)#router ospf 10
R1(config-router)#redistribute eigrp 100 subnets route-map CCNP

Here the route with the tag 200 is the only one which will be redistributed. This will advertise the correct subnet.

EC302 has a bug in the question. The answer is marked incorrect. Even the answer that How2pass gives is barked incorrect.

I had done a searching in this link "https://www.cisco.com/c/en/us/td/docs/routers/ios/config/17-x/sec-vpn/b-security-vpn/m_ipv6-src-guard-xe.html" and it stands that Ipv6 source guard and Ipv6 Prefix list are Layer 2 snooping feaures and validate the source of the traffic.

But Ipv6 prefix list are not in the correct answers. Can you explain me why please ?

In the question with QID AR429, in my opinion, and others that i saw on internet, AS-OVERRIDE at the PE HUB is the best answer, once It is The PE HUB which will announce to the CE a prefix which contains the oher CE AS, which is the same. Can you verify this for me please ?

Thank you !
