The given Answer is wrong. 

The correct answer should be LDP uses SSO to recover from disruption in control plane service.

"Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) uses SSO, NSF, and graceful restart to allow a Route Processor (RP) to recover from disruption in control plane service (specifically, the LDP component) without losing its MPLS forwarding state."

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 ?

Believe you would "Resolve metric differences between the peers to calculate the valid K-value" They have already been configured and do not match as the log message shows K-value mismatch.

Question: Which action implements physical access control as part of the security program of a Organization?

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 !
