NEW QUESTION # 152
Huawei Open Programmability System (OPS) uses standard HTTP methods to access managed objects to manage network devices. Which of the following HTTP methods is used to configure the value of a network device's managed object?
Answer: D
Explanation:
Huawei Open Programmability System (OPS) is a programmable network architecture that uses RESTful APIs. In RESTful operations:
GET โ Retrieve data
PUT โ Configure/replace the value of a managed object
POST โ Create new resources or perform non-idempotent operations
PATCH โ Partially update a resource
When configuring or updating the value of a managed object (fully replacing it), PUT is the correct method.
Exact Extract - Huawei OPS and RESTful API Guide:
"The PUT method is used to configure the value of a managed object, replacing the entire object if it exists." Reference:

NEW QUESTION # 153
On a CloudCampus virtualized campus network, virtual networks are defined based on services. Each virtual network corresponds to a service, and isolation needs to be manually configured between virtual networks.
Answer: B
Explanation:
* Virtual Networks in Huawei CloudCampus Solution:
* Virtual networks (VNs) are segmented based on services (e.g., IoT, Guest Wi-Fi, Enterprise Wi- Fi).
* Each VN has its own routing and forwarding instance (VRF).
* Isolation Between Virtual Networks:
* By default, different virtual networks are isolated.
* If inter-VN communication is required, it must be manually configured using policy-based routing (PBR), inter-VRF routing, or firewall policies.

NEW QUESTION # 154
As shown in the figure,ARP broadcast suppression is enabled on VTEP1inBD 20 (VNI 200).
VTEP1 learns ARP informationaboutPC2 through BGP EVPN routes.
WhenVTEP1 forwards the ARP request for PC1's MAC address to VTEP2,
What is the destination MAC address of the inner data frame?
Answer: D
Explanation:
Understanding VXLAN and ARP Suppression in BGP EVPN
VXLAN (Virtual Extensible LAN) is used toextend Layer 2 networks over Layer 3 infrastructure.
VXLAN uses VTEPs (VXLAN Tunnel Endpoints) to encapsulate and forward Layer 2 traffic.
BGP EVPN (Ethernet VPN)is used forMAC/IP address learning and distributionacross VXLAN networks.
How ARP Request Forwarding Works in This Scenario?
1##ARP Broadcast Suppression Enabled (VXLAN Optimized Forwarding)
SinceARP broadcast suppressionis enabled onVTEP1, theARP request is not flooded.
Instead, VTEP1checks its EVPN learned databaseto findPC2's MAC address (MAC C).
2##VTEP1 Encapsulates the ARP Request
VTEP1encapsulates the ARP request in a VXLAN packetand sends it toVTEP2.
Theoriginal ARP frame inside the VXLAN tunnel still has:
Source MAC:MAC A(PC1 ' s MAC)
Destination MAC:MAC C(PC2 ' s MAC, learned via EVPN)
3##VXLAN Outer Headers
Theouter VXLAN headeruses:
Source IP:1.1.1.1 (VTEP1)
Destination IP:2.2.2.2 (VTEP2)
VNI (VXLAN Network Identifier):200(BD 20)
4##VTEP2 Receives and Forwards the ARP Request
VTEP2 decapsulates the VXLAN packetand forwards theoriginal ARP requesttoPC2 (MAC C).
This ensures thatonly the intended receiver (PC2) gets the ARP request, preventing unnecessary broadcast flooding.
Why the Answer is MAC C?
#B. MAC C is Correct
Thedestination MAC of the inner data frameisPC2's MAC (MAC C).
This is becauseVTEP1 forwards the ARP request directly to VTEP2, which then forwards it to PC2.
Why Other Answers Are Incorrect?
#A. MAC B (Incorrect)
MAC B is VTEP1's MAC address, which is used in theouter VXLAN header, not in the inner Ethernet frame.
#C. MAC A (Incorrect)
MAC A is the source MACof the ARP request (PC1), not the destination.
#D. MAC D (Incorrect)
MAC D is not mentioned in the topology, so it is irrelevant.

NEW QUESTION # 155
MPLS supports both static and dynamic LSP establishment. Which of the following protocols cannot dynamically establish LSPs in MPLS TE scenarios? (Select all that apply)
Answer: A,C,D
Explanation:
InMPLS Traffic Engineering (TE),Label Switched Paths (LSPs)can be established:
Statically: Manual configuration.
Dynamically: Typically viaRSVP-TE.
Protocol roles:
RSVP-TE:Used to dynamically establish and signal TE LSPs##
OSPF / IS-IS: Act asIGP protocolsand provide TE-related link-state information (like bandwidth) butdo not establish LSPs themselves## BGP: Used forroute advertisement, not forLSP setupin MPLS TE ## Correct answers: A, C, D
