NEW QUESTION # 16
In 6PE and 6VPE networking, no VPN instance needs to be created on PEs.

A. TRUE
B. FALSE

Answer: A

Explanation:
Understanding 6PE & 6VPE in MPLS Networks
6PE (IPv6 Provider Edge) and 6VPE (IPv6 VPN Provider Edge) are MPLS-based solutions that allow IPv6 traffic to be carried over an MPLS IPv4 core network without requiring the entire backbone to support IPv6.
# 6PE (IPv6 over MPLS - No VPN)
* Used for global IPv6 routing without VPN segmentation.
* No need for VRFs (VPN Routing and Forwarding instances) because IPv6 prefixes are handled natively.
# 6VPE (IPv6 VPN over MPLS - Supports VPNs)
* Extends MPLS L3VPN to support IPv6 routing inside VPN instances.
* Uses MP-BGP VPNv6 to distribute IPv6 prefixes inside MPLS VPNs.
Why is the Answer TRUE?
# No VRFs are required for 6PE:
* 6PE only needs BGP labeled IPv6 routes in the global routing table.
* IPv6 prefixes are carried using MPLS labels without VPN segmentation.
# VRFs are required for 6VPE, NOT for 6PE:
* 6VPE requires VPN instances (VRFs) for IPv6 L3VPNs, but 6PE does not.
# Real-World Application:
* 6PE is used in large ISP networks where IPv6 deployment is needed but without VPN separation.
* 6VPE is used for enterprise MPLS VPNs, allowing customers to have isolated IPv6 routing tables.

NEW QUESTION # 17
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculations. As shown in the figure, at the same time, a certain area has IPV4 and IPV6 and runs IS-IS to achieve network interconnection, of which R2 only supports IPV4 Regarding the topology calculation of the network, which of the following statements is correct?

A. If you want the IPv4 and IPv6 networks to compute the same shortest path tree. The IPv6-enable topology lpv6 command is required to enable the Russian force of IPv6 under the IS-IS process
B. By default, IPv6 is not supported because R2 Therefore, in the shortest path tree formed by the JPv6 network computation, the path where R1 accesses R4 is: R1-R3-R4
C. By default, in the shortest path tree formed by the IPv6 network calculation, R1 accesses R4 as R1-R2-R4, since R2 does not support IPv6 Therefore, R2 will directly drop the IPv6 packet after receiving it, and select the traffic loss
D. By default, IPv4 and IIPV6 networks are computed separately to form different shortest path trees

Answer: C

NEW QUESTION # 18
In Huawei SD-WAN Solution, which of the following tunneling technologies is used to establish data channels?

A. MPLS
B. IPsec
C. WLAN
D. GRE over IPsec

Answer: B,D

Explanation:
Understanding Huawei SD-WAN Tunneling Technologies
Huawei SD-WAN usessecure tunnelingto connect branches, data centers, and cloud services.
#Tunneling Technologies in SD-WAN:
#IPsec (Answer B)# Providessecure encrypted tunnelsover public or private networks.
#GRE over IPsec (Answer D)#Encapsulates traffic inside GRE, then encrypts with IPsec, enabling support for multicast and non-IP traffic.
#A. WLAN (Incorrect Choice)# WLAN is awireless technology, not a tunneling protocol.
#C. MPLS (Incorrect Choice)# MPLS is acore network transporttechnology but is not used to establish SD- WAN data channels directly.
Why are Answers B and D Correct?
#Huawei SD-WAN primarily uses IPsec for data encryption.
#GRE over IPsec is used when supporting multicast or dynamic routing protocols over tunnels.
#Reference:Huawei HCIE-Datacom Guide - SD-WAN Tunneling Mechanisms

NEW QUESTION # 19
What kind of scenario can use AS one path and one filter?

A. The apply clause in Routepolicy
B. Filter routes received from BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peer x.X.x.x as path-filter import
C. Filter routes sent to BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peerx. X.x.x as path-filter export
D. If-natch clause answer in Route-policy.

Answer: B,C,D
