Q1. You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire). Service Provider XYZ has these design requirements: 

The network supports four service queues with equal treatment for delay, jitter, and packet loss. 

Queues are numbered 0-3, where 0 is the default queue. 

Three queues have one treatment. 

One queue has either one or two treatments. 

If your design includes eight CoS queues on the Service Provider XYZ MPLS PE router ingress (CE facing) interface, how will customer traffic be classified as it enters the MLS P routers? 

A. The eight CoS queues in the MPLS P router are remapped to the eight CoS queues. 

B. Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers. 

C. Discard the traffic from the eight CoS queues that does not match the four CoS queues of the MPLS P routers. 

D. The 8 CoS queues in the MPLS P router are remapped to four 4 flow-label queues.

Q3. Refer to the exhibit. 

Service Provider A and Service Provider B have agreed to a strategic interconnect relationship that will allow them access into each other's geographies by using an inter-AS eBGP VPNv4 multihop between route reflectors. Which two options will accomplish this scenario? (Choose two.) 

A. RR 1 and RR 2 peer using multihop eBGP VPNv4 to exchange prefixes. 

B. ASBR 1 and ASBR 2 act as inline route reflectors that set themselves as the next-hop. 

C. An LSP is formed between ASBR 1 and ASBR 2 using eBGP IPv4. 

D. An LSP is formed between ASBR 1 and ASBR 2 using eBGP VPNv4. 

E. RR 1 and RR 2 peer using multihop eBGP IPv4 to exchange prefixes.

Q4. A company wants to connect two data center sites using a hub-and-spoke design with 2000 remote sites. One design consideration is the requirement to transfer MPLS packets over the public Internet. In addition, one router at each site should be used, and the MPLS packets must be encapsulated inside IP packets because the public Internet cannot transfer native MPLS packets. Which feature can be used to simplify the network design? 

A. GET VPN can be used to encrypt the MPLS packets with IPsec. 

B. DMVPN can be used to build up GRE tunnels dynamically with MPLS encapsulation inside. 

C. L2TPv3 can be used to encapsulate the MPLS packets. 

D. Site-to-site IPsec without GRE can be used to encapsulate the MPLS packets. 

E. PPPoE can be used to encapsulate the MPLS packets.

C. traffic black-holing 

D. packet reordering

A. Incremental Shortest Path First 

B. Cisco Multiprotocol Label Switching Traffic Engineering Fast Reroute 

C. Loop-Free Alternate Fast Reroute 

D. partial route calculation 

E. Fast-Flooding

Q7. 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

Q8. What is the definition of the ITIL framework? 

A. an ISO framework that establishes a model for network management and contains guidelines for managing objects, the management database, and the application entity 

B. a five-volume framework for service management that covers design, transition, and delivery of service, and from which the ISO 20000 was developed 

C. a series of tools for process improvement that uses statistical methods to reduce defects in processes and manufacturing 

D. a framework for enterprise architecture that provides a comprehensive approach for designing, planning, implementing, and governing an enterprise information architecture 

E. a framework for enterprise IP Address Management (IPAM) based on the IANA trusted IP lease allocation scheme

Q9. Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario? 

A. ISATAP 

B. 6to4 

C. DMVPN 

D. 6vPE 

E. 6PE

Q10. 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. Build a dual-stack network. Enable BGP in the core. Redistribute EBGP routes into IGP. 

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. 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. 

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.
