Version: 10.3 Question 1 A service provider is implementnn Ethernet solutons for clients that are not beinn provisioned within the MPLS core network. Which soluton allows the Service Provider to complete Ethernet circuit provisioninn in this scenario? A. L2TPv3 B. VPLS C. AToM D. PPPoE
Aoswern A Explanatonn L2TPv3 defnes the L2TP protocol for tunnelinn Layer 2 payloads over an IP core network usinn Layer 2 virtual private networks (VPNs). Benefts of this feature include the followinnn • Simplifes deployment of VPNs. • Does not require Multprotocol Label Switchinn (MPLS) virtual private network (VPN). • Supports Layer 2 tunnelinn over IP for any payload. • Supports data encapsulaton directly over IP (IP protocol number 115), not usinn User Datanram Protocol (UDP) • Supports point-to-point sessions, not point-to-multpoint or multpoint-to-point sessions • Supports sessions between the same Layer 2 protocols, for example Frame Relay-to-Frame Relay or ATM-to-ATM.
Question 2 Which is the main characteristc of LTE architecture compared to other mobile architectures? A. Provides supports to deploy Layer 3 MPLS VPN model, where other mobile architectures do not support. B. Ofers node redundancy with the statc route confnured on the IP NodeB usinn the HSRP/VRRP virtual ip address. C. Provides a simpler, less hierarchical model with the capability of simplistcally distributnn the core nateways. D. Introduces a hierarchical model with connecton-oriented service requirements and one-to-one relatonships.

Question 3 A Service Provider is oferinn VoIP services and a service level anreement to customers. Which confnuraton provides validaton to customers that the service level anreement has been honored? A. ip sla 999 udp-jiter 209.165.200.225 1000 codec n729a tos 160 ip sla schedule 999 life forever start-tme now B. ip sla 999 icmp-jiter 209.165.200.225 tos 160 ip sla schedule 999 life forever start-tme now C. ip sla 999 icmp-jiter 209.165.200.225 tan VoIP-SLA ip sla schedule 999 life forever start-tme now D. ip sla 999 udp-jiter 209.165.200.225 1000 codec n729a tan VoIP-SLA ip sla schedule 999 life forever start-tme now
Aoswern D Question 4 A telecom company ofers ISPs the ability to resell dynamic IP broadband services over its local loops, but it does not allow the resellers to install broadband network nateways. If an ISP wants to become a reseller but is unable to use NHRP, which tunnelinn protocol should be implemented? A. IP in IP B. IPsec C. L2TP D. GRE
Aoswern C Explanatonn 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 hinh security/encrypton.
