* In firewall hot standby (HRP - Hot Standby Routing Protocol) mode, certain data can be synchronized between the active and standby firewalls to ensure uninterrupted service.
* The following data is backed up:
* # Server mapping table: Contains information about NAT mappings and other session mappings.
* # AAA user table (excluding the default user admin): Ensures that authenticated users do not need to re-authenticate in case of failover.
* # Session table: Ensures that existing connections remain active when switching to the standby firewall.
* # Dynamic MAC address table is NOT backed up because it is dynamically learned and not relevant to firewall session synchronization.

Comprehensive and Detailed Explanation:
# Huawei OPS (Open Programmability System) is a YANG-based network management system that uses RESTful APIs for configuring and managing devices.
# /ifm/interfaces/interface is the RESTful URI (Uniform Resource Identifier) that:
* Represents an interface object in the network device.
* Allows querying, configuring, and modifying network interfaces via API requests.
Since the statement is correct, the answer is TRUE.

InOSPFv3, each LSA type has adefined flooding scope:
Link-LSA (Type 8)
Advertisedonly on the local link
Contains router's link-local address and prefixes
Scope:Within the local link scope#
AS-External-LSA (Type 5)
Used to advertiseexternal routes from outside the AS
Flooded across theentire autonomous system, except stub/NSSA areas
Scope:Within an AS#
Network-LSA (Type 2)
Generated by theDesignated Router (DR)
Describes all routers on a broadcast or NBMA segment
Floodedwithin the originating area
Scope:Within an area#
Correct Mappings:
Link LSA#Within the local link scope
AS-External-LSA#Within an AS
Network-LSA#Within an area
