QUESTION NO: 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?

A. L2TPv3

B. VPLS

C. AToM

D. PPPoE

Answer: A

Explanation:

L2TPv3 defines the L2TP protocol fortunnelingLayer 2 payloads over an IP core network using

Layer 2 virtual private networks (VPNs). Benefits of this feature include the following:

•

Simplifies deployment of VPNs.

•

Does not require Multiprotocol Label Switching (MPLS) virtual private network (VPN).

•

Supports Layer 2tunnelingover IP for any payload.

•

Supports data encapsulation directly over IP (IP protocol number 115), not using User Datagram

Protocol (UDP)

•

Supports point-to-point sessions, not point-to-multipoint or multipoint-to-point sessions

•

Supports sessions between the same Layer 2 protocols, for example Frame Relay-to-Frame Relay

or ATM-to-ATM.

QUESTION NO: 2

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

A. Provides supports to deploy Layer 3 MPLS VPN model, where other mobile architectures do

not support.

B. Offers node redundancy with the static route configured on the IP NodeB using the

HSRP/VRRP virtual ip address . 2

C. Provides a simpler, less hierarchical model with the capability of simplistically distributing theAnswer: C

become a reseller but is unable to use NHRP, which tunneling protocol should be implemented?

A. IP in IP

B. IPsec

C. L2TP

D. GRE

Answer: CExplanation:

However, while OpenVPN can not be used with VoIP, L2TP can be used for VoIP. Only use this if

OpenVPN is not available and you are in need of very high security/encryption.
