Auto summarization determines which routes are advertised.  R1 and R3 are both advertising 172.16.0.0/16.  

Changing auto summarization on R2 will have no impact.

adding a static route to 172.16.2.0 with a more specific mask will resolve the issue

EIGRP Summarization should  be configured at R1's neighbor to correct this problem.  Changing the summary-address at R1 would determine what summary addresses R1 advertises.

i used other sims and have noticed that i could learn and remember them way better when the order of the answers was everytime randomly changed.
pretty sure everyone else would love this feature too!

the answer with the "action 1.0 cli command "end"" should be right.
i belive its "ena" and not "end" but yeah..

Hello How2Pass - when were the questions updated last - are all current questions thought to be on the current exam?

Also - is there a reason you do not have an option to change the ordering of the multiple choice answers, are they in this order by design?

And for anyone else, I am wondering if anyone passed recently who has taken 350-401 ENCOR, and what was your experience.

right answer is:

Apply a filter list inbound on R3 and R7.

EC574: there is missing a passive-interface command on the right answer

Correct answer should be:

Set max-bundle to 2 ...


please check and change right answer if it is really wrong

I started to see ospf issues on only one of the tunnels. It was happening before I configured crypto isakmp policy.  I think it was r1 to r3.  The only task was to configure IPSEC over the tunnel.   The PC off of R1 could never ping the pc off of R3.  It made sense because the tunnel was bouncing.  Show dmvpn looked fine on both spokes.   The IPSEC configs were exactly the same on 3 devices.  The tunnel configs were exactly the same on all nodes.   I spent way too much time on this sim and failed the exam.  Anyone else see this issue.
