A network administrator deployed IKEv2 Cisco AnyConnect on a Cisco ASA. The current configuration tunnels all traffic through the VPN. Users report poor performance with cloud-based applications, but no issues have been reported about connections to on-premises servers. Packet analysis on Cisco Webex traffic shows very few duplicate ACKs, high RTT, and no IP fragments. Which action improves Webex performance for VPN users?

  • A. Configure QoS on the outside interface of the ASA.
  • B. Configure Cisco AnyConnect to use DTLS.
  • C. Configure a dynamic split tunnel exclusion.
  • D. Reduce the Cisco AnyConnect tunnel MTU.

Selected Answer: B
RTT is a clue that latency is not a problem. Split tunnel does not improve traffic in cases where ISP issue may provide lesser quality performance. So reconfiguration is not warranted. B is none to deal with time-sensitive traffic, which the cloud solution are mostly.

It says High RTT, which indicates that latency is THE problem. Dynamic Split Tunnel Exclusion is the solution here. I go with C.

Selected Answer: B
C is incorrect as no one told us we can exclude cloud traffic from traversing ASA (maybe they do some filtering etc.?) B is logical as cisco itself mention that DTLS improves latency and also voice quality which is webex

C...dynamic split tunnel uses DNS info to determine what traffic to be tunneled works to improve webex traffic
