thanks! mine says 760 is the passing score

Passed exam - very low score - 800. 195+42 questions - still valid, I am pretty sure some answers are not correct.

yeah, this is very tricky, but I take a closer look at some of the requirements like "without any routing changes in the network" and "without incurring any IP address change " and " extend their existing IP CCTV network" . In the question, I assume the added branch has connectivity already with the HQ, so all routing is sorted out. I think if you add GRE , it really does not help extend the network. You are just creating a point to point tunnel between the HQ and Branch. If you do L2TPV3, you can actually extend the L2 network over the existing IP network. Below is from networklessons which for me help illustrate the requirement above, [Hidden Content] Let me know what you think?

A legacy enterprise is using a Service Provider MPLS network to connect its head office and branches. Recently, they added a new branch to their network. Due to physical security concerns, they want to extend their existing IP CCTV network of the head office to the new branch, without any routing changes in the network. They are also under some time constraints. What is the best approach to extend the existing IP CCTV network to the new branch, without incurring any IP address changes? A. GRE B. L2TPv3 C. VXLAN D. EoMPLS I believe the best answer here is L2TPv3. Reason being is we only want to extend the IP CCTV network of the head office to the new site. If EoMPLS - the service provider needs to configure this on their PE (which is the demarcation point) for the MPLs network. If they go via EoMPLS route , the whole interface to the CE will be affected. If they go via L2TPv3, all they need to do is configure xconnects on their existing routers at both HO and the new site and tunnel them through the MPLS network.

Hey guys...regarding this question Refer to the exhibit. Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10.1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain. Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue? A. The LA administrator should use route dampening for the 10.1.5.0/24 network so that it does not get propagated when it flaps up and down. B. The Chicago administrator should use route filtering to block the 10.1.5.0/24 network from coming in from the LA router. C. The LA administrator should use route aggregation to summarize the 10.1.4.0/24, 10.1.5 0/24, 10.1.6.0/24, and 10.1.7.0/24 networks toward Chicago. D. The LA administrator should use route filtering to block the 10.1.5.0/24 network from getting propagated toward Chicago and New York. Isn't it option A is also a possible answer?
