You are designing the QoS features for a large enterprise network that includes DMVPN. In which situation should you use the QoS pre-classify feature?

• A.When you are marking packets with the ToS bits
• B.When your service provider requires the DSCP bits be set
• C.When you are marking packets with the DSCP bits
• D.When the QoS policy cannot be based on DSCP bits

Drag and drop the optical technology design characteristics on the left to the correct optical technologies on the right. Not all options are used.

Correct Answer:

Which two design aspects should a metro service provider consider when planning to deploy REP for his backbone? (Choose two.)

• A.VLAN load balancing for optimal bandwidth usage is supported in any REP segment.
• B.A REP segment is limited to a maximum of seven devices.
• C.UDLD can be enabled on REP interfaces to detect unidirectional failures.
• D.Two REP segments can be connected redundantly at two points, one connection will be blocked as per the STP defined in IEEE 802.1d.
• E.The guaranteed convergence recovery time is less than 50 ms for the local segment.

What are two possible drawbacks of ending Loop-Free Alternate to support fast convergence for most destination IGP prefixes? (Choose two)

• A.Loop-free alternate's are supported only for prefixes that are considered external tot the IGP
• B.Loop-free alternate's convergence in less than 100 milliseconds is not possible
• C.Additional path computations are needed
• D.The IGP topology might need to be adjust
• E.Loop-free alternates are not supported in global VPN VRF OSPF instances

A DMVPN network is being deployed for 10 branch sites to connect to the central headquarters over the Internet. Each branch site connects to the internet via a 1.5 Mb/s ADSL line, and the headquarters connects to the Internet over a 100Mb/s circuit limited to 20 Mb/s by the service provider. Which QoS mechanism if any, do you recommend at the headquarters location?

• A.QoS is not required in this instance due to maximum traffic being received by the branches being 15 Mb/s
• B.Applying hierarchical QoS with parent policy for the overall circuit and child policy for the spokes
• C.Traffic shaping the 100 Mb/s circuit to 20 Mb/s
• D.Rate-limiting the 100 Mb/s circuit to 20 Mb/s
