NEW QUESTION # 264
An SRv6 Policy can be either statically configured on a device, or be delivered to a device after being dynamically generated by the controller.
Answer: A
Explanation:
SRv6 Policies can be:
Statically configured via CLI on routers.
Dynamically generated and delivered from a controller such as Huawei iMaster NCE for centralized path computation.
This dual approach allows flexibility in deployments.
Exact Extract - Huawei SRv6 Deployment Guide:
"SRv6 Policies can be locally configured or dynamically delivered via PCEP from the controller, enabling both static and SDN-based implementations." Reference:

NEW QUESTION # 265
The BGP ORF function can be used to control the maximum number of routes that can be sent by a BGP peer. To achieve this, which of the following tools is used to send such a route list to BGP peers?
Answer: B
Explanation:
Comprehensive and Detailed In-Depth
The Outbound Route Filtering (ORF) function in BGP allows a BGP speaker to inform its peer about the prefixes that it wants to receive, thereby reducing unnecessary route advertisements.
IP Prefix-List (D) is the correct answer because it is used to define the list of prefixes that are sent to the BGP peer during the ORF capability negotiation.
Filter-policy (A) and Route-policy (B) are used for controlling routing information locally or filtering incoming/outgoing routes but do not directly control the number of routes sent using ORF.
ACL (C) is primarily used for packet filtering and is not related to BGP route filtering.

NEW QUESTION # 266
SR-MPLS uses the MPLS forwarding plane, and therefore requires MPLS to be enabled. Which of the following conditions must be met for MPLS to be automatically enabled on an interface? (Select all that apply)
Answer: A,D
Explanation:
To automatically enable MPLS on an interface in SR-MPLS:
Segment routing must be enabled globally in the system view → ✅
Segment routing must also be enabled under the IGP process, and IGP (OSPF or IS-IS) must be enabled on the interface → ✅ Clarifications:
SRGB (Segment Routing Global Block) configuration defines SID ranges but does not trigger MPLS enablement → ❌ Static adjacency labels are advanced options and do not auto-enable MPLS → ❌ Correct answers: B, D
NEW QUESTION # 267
What are the three ways to send IPv4 messages?
Answer: A,C,D
NEW QUESTION # 268
A 32-bit MPLS header consists of a 20-bit label used for packet forwarding, a 3-bit EXP field that identifies the IP packet priority, a 1-bit bottom-of-stack flag that identifies the last label, and an 8-bit TTL field. Which statement regarding the TTL field is correct?
Answer: B
Explanation:
TheMPLS headerconsists of:
Label (20 bits)- Label value used for forwarding.
EXP (3 bits)- QoS field (Class of Service).
S bit (1 bit)- Bottom-of-Stack indicator.
TTL (8 bits)-Time-to-Live, similar to the TTL field in the IP header.
Function of TTL in MPLS:
It is used toprevent infinite loops.
Every LSRdecrementsthe TTL by 1.
When TTL reaches0, the packet isdiscarded.
This mirrors the behavior of IP TTL and ensures loop prevention in MPLS networks.
Correct answer: D. This field is used to prevent packet forwarding loops, similar to the TTL field in an IP header.
