Question: 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 for tunneling Layer 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.

Label Switching (MPLS) virtual private network (VPN).
•Supports Layer 2 tunneling over IP
for any payload.

Question: 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?
A.
IP in IP
B.
IPsec
C.
L2TP
D.
GRE
Answer:
C
Explanation:
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.
