1.

A service provider is implementing Ethernet solutions for clients that are not being provisioned within the MPLS core network. Which solution allows the Service Provider to complete Ethernet circuit provisioning in this scenario?

L2TPv3 VPLS AToM PPPoE

2.

Which is the main characteristic of LTE architecture comparing to other mobile architectures?

Provides supports to deploy Layer 3 MPLS VPN model, where other mobile architectures do not support. Offers node redundancy with the static route configured on the IP NodeB using the HSRP/VRRP virtual ip address. Provides a simpler, less hierarchical model with the capability of simplistically distributing the core gateways. Introduces a hierarchical model with connection-oriented service requirements and one-to-one relationships.

3.

A Service Provider is offering VoIP services and a service level agreement to customers. Which configuration provides validation to customers that the service level agreement has been honored?

ip sla 999 udp-jitter 209.165.200.225 1000 codec g729a tos 160
ip sla schedule 999 life forever start-time now ip sla 999 icmp-jitter 209.165.200.225 tos 160ip sla schedule 999 life forever start-time now ip sla 999 icmp-jitter 209.165.200.225 tag VoIP-SLAip sla schedule 999 life forever start-time now ip sla 999 udp-jitter 209.165.200.225 1000 codec g729a tag VoIP-SLAip sla schedule 999 life forever start-time now

4.

A telecom company offers ISPs the ability to resell dynamic IP broadband services over its local loops, but it does not allow the resellers to install broadband network gateways. If an ISP wants to become a reseller but is unable to use NHRP, which tunneling protocol should be implemented?

IP in IP IPsec L2TP GRE

5.

A Service Provider provides a Layer 2 connection that is based on IEEE 802.1ad. When the customer tries to access a switch at the other side of the link by using SSH, the connection fails.
What is the cause of this failure?

The Service Provider omitted the command l2protocol-tunnel stp. The Service Provider omitted the command l2protocol-tunnel vtp. The Service Provider omitted the command vlan dot1q tag native. The Service Provider omitted the command spanning-tree bpdufilter enable.

6.

In an MPLS VPN environment, the QoS marking over the MPLS backbone must be different from the one that is received from the customer. The forwarding on the egress PE is based on the marking that is set by the ingress PE. Which null label and QoS mode can achieve this?

MPLS explicit null with pipe mode MPLS implicit null with short pipe mode MPLS implicit null with uniform mode MPLS explicit null with uniform mode MPLS explicit null with short pipe mode

7.

An engineer is deploying RTBH. What is necessary routing constraint required for successful implementation?

The trigger device must have an iBGP session with all the clusters/route reflectors in the autonomous system. The trigger device must redistribute the static route pointing to a null interface into the IGP process. The no ip reachables command must be issued on the PE router interface under attack. The attacker's destination IP address must be routed to a null interface. The eBGP sessions need to set the next-hop attribute value to the trigger device loopback interface.

8.

Which Cisco IOS XR Virtualization technology provides full isolation between virtualized routing instances for extra control plane resources?

HVR SVR SDR DRP

9.

An engineer wants to configure MPLS TE Fast Reroute with link protection on five routers. Which methodology can reduce configuration on the point of the local repair router and successfully complete the task?

Configure a backup tunnel on the PLR. Enable the autotunnel backup feature. Configure a backup tunnel on the tunnel head end router. Enable the autotunnel primary feature.

10.

What is NETCONF?

It is a standard for installing, manipulating and deleting configuration of network devices. It is a Cisco proprietary solution to help remove the time, cost and manual steps involved in network element configuration. It is data modeling language, to help remove the time, cost and manual steps involved in network element configuration. It is a new recommendation which writes device specific CLI scripts while keeping flexibility in a vendor dependence environment.
