NEW QUESTION 24
Refer to the exhibit.
An enterprise has three sites over a Layer 2 Metro Ethernet ELAN service. 100Mb/s and 10 Mb/s links have been provisioned to provide redundancy for the head office. When OSPF routing enabled to provide connectivity and the correct bandwidth statement has been applied to each interface, the branch sites observe two equal-cost routes to the head office. The enterprise wants to send all traffic through the 100 Mb/s link and use the 10Mb/S link strictly as a backup. Which OSPF network type must be set to ensure that the head office
100 Mb/s circuit is preferred over the 10 Mb/s circuit, at the same time minimize the amount of configuration required on all of the routers throughout the network?
- A. Point-to-point
- B. Broadcast
- C. Point-to-multipoint
- D. NBMA
Answer: A
NEW QUESTION 25

NEW QUESTION 26
You are the lead IP network designer for a new service provider called XYZ, and you are working closely with the CTO to finalize design requirements. The CTO informs you that they want to transport IPv6 prefixes of customers through the XYZ network at this time; however, they need your advice on whether to deploy dual stack or MPLS 6PE/6VPE. Which two options do you recommend? (Choose two.)
- A. Use MPLS 6VPE to simplify the operation and keep a BGP-free core. When the LDPv6 becomes available, change to 4PE or keep the core using both IPv4 and IPv6. The main goal is to keep the core BGP-free and ensure that IPv4, IPv6, VPNv4, and VPNv6 are all label-switched.
- B. Use MPLS 6PE to simplify the operation and keep a BGP-free core. When the LDPv6 becomes available, change to 4PE or keep the core using both IPv4 and IPv6. The main goal is to keep the core BGP-free and ensure that IPv4, IPv6, VPNv4, and VPNv6 are all label-switched.
- C. Build a dual-stack network. Enable BGP in the core. Redistribute EBGP routes into IGP.
- D. Prepare the dual-stack infrastructure from the beginning, even if BGP prefixes would have to be announced via IPv4 in case you decide to maintain the BGP-free core.
Answer: B,D
NEW QUESTION 27
A service provider sets up LSP among all the edge routers in its network by using LDP. A user would like to maintain its DSCP marking across the service provider backbone. Mark the MPLS packets with the appropriate EXP values according to QoS policies.
Which step should be taken to classify and queue packets on egress nodes on the basis of EXP marking?
- A. copy MPLS EXP at penultimate hop into DSCP
- B. copy IP DSCP at the ingress into MPLS EXP
- C. use MPLS network-wide QoS propagation
- D. disable penultimate hop popping
