An engineer has integrated a new DMVPN to link remote offices across the internet using Cisco IOS routers. When connecting to remote sites, pings and voice data appear to flow properly and all tunnel stats seem to show that are up. However, when trying to connect to a remote server using RDP, the connection fails. Which action resolves this issue?
A. Change DMVPN timeout values.
B. Adjust the MTU size within the routers.
C. Replace certificate on the RDP server.
D. Add RDP port to the extended ACL.
Correct Answer: B
Explanation/Reference:
Explanation:
Answers A and C do not make sense.
Answer D is valid only for split tunneling…if we want to pass the RDP traffic off tunnel. The ACL configured to establish the DMVPN tunnel only need udp 500/4500 and esp (50).
Answer B should be correct because voice traffic (UDP) and ping use smaller MTU size and will not be fragmented…and thus will work. RDP uses TCP / 3389 and isn’t fault tolerant.
