Q31. You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network. If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?
A. map DSCP bits into the Exp field
B. map IP precedence bits into the DSCP field
C. map flow-label bits into the Exp field
D. map IP CoS bits into the IP Precedence field
E. map IP ToS bits into the Exp field
Answer: A
Q32. A multicast network is using bidirectional PIM. Which two actions, when combined, can achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two.)
A. Use Anycast RP based on MSDP peering between the two RPs.
B. Use a phantom RP address.
C. Advertise routes for the two RPs with the same subnet mask through the unicast routing protocol.
D. Advertise routes for the two RPs with different subnet mask lengths through the unicast routing protocol.
E. Manipulate the administrative distance of the unicast routes to the two RPs.
F. Manipulate the multicast routing table by creating static mroutes to the two RPs.
Answer: BD
Q33. In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?
A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.
B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.
C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.
D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.
Answer: C
Q34. Which mechanism provides a Layer 2 fault isolation between data centers?
A. TRILL
B. LISP
C. advanced VPLS
D. OTV
E. fabric path
Answer: D
Q35. Refer to the exhibit.
How would you redesign the network to improve availability of the routers 1A and 1B at the core site?
A. Enable Graceful Restart Helper for OSPF
B. Use link bundles over multiple slots
C. Use APS Ethernet circuits and redundant interfaces
D. Create a multichassis system with the two routers
Answer: D

Q36. You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.)
A. native IPv6, only for multicast services
B. MPLS 6PE/6VPE, because it provides IPv6 multicast support by default
C. an overlay model using Layer 2 MPLS tunnels
D. PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE
E. MVPN for IPv6 multicast service
Answer: ACE
Q37. Your company plans to implement an Internet gateway router that is performing NAT. This same gateway will be terminating various IPsec tunnels to other remote sites. Which
address type isappropriate for the ACL that will govern the sources of traffic entering the tunnel in the inside interface?
A. inside local
B. inside global
C. outside local
D. outside global
Answer: B
Q38. Refer to the exhibit.
The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable, and the core devices are OSPF graceful restart-aware. The WAN advertisements received from BGP are redistributed into OSPF. A forwarding supervisor failure event takes place on CE A. During this event, how will the routes learned from the WAN be seen on the core devices?
A. via CE A and CE B
B. via CE A
C. via CE B
D. no WAN routes will be accessible
Answer: C
Q39. You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.)
A. EtherChannel
B. MST
C. Multichassis EtherChannel
D. PVST+
Answer: AC
Q40. You are working on a network design plan for a company with approximately 2000 sites. The sites will be connected using the public Internet. You plan to use private IP addressing in the network design, which will be routed without NAT through an encrypted WAN network. Some sites will be connected to the Internet with dynamic public IP addresses, and these addresses may change occasionally. Which VPN solution will support these design requirements?
A. GET VPN must be used, because DMVPN does not scale to 2000 sites.
B. DMVPN must be used, because GET VPN does not scale to 2000 sites.
C. GET VPN must be used, because private IP addresses cannot be transferred with DMVPN through the public Internet.
D. DMVPN must be used, because private IP addresses cannot be transferred with GET VPN through the public Internet.
E. GET VPN must be used, because DMVPN does not support dynamic IP addresses for some sites.
F. DMVPN must be used, because GET VPN does not support dynamic IP addresses for some sites.
Answer: D
