What are the basic roles of devices in the typical MPLS VPN technical architecture? (Select All that Apply)

  1. PE
  2. Aggregation
  3. P
  4. Core
  5. CE

Answer(s): A,C,E

Explanation:

MPLS VPN Architecture Overview:

MPLS (Multiprotocol Label Switching) VPN is a widely used technology for creating virtual private networks over a shared infrastructure. It involves specific roles for devices in the network.

Explanation of Each Role:

PE (Provider Edge):These devices sit at the edge of the service provider's network and connect to customer sites. They are responsible for assigning labels and managing VPN routes.

P (Provider):These devices are located in the core of the service provider's network.They perform label switching but do not participate in VPN-specific functions.

CE (Customer Edge):These devices belong to the customer and connect to the PE devices. They are unaware of the MPLS network and simply forward traffic to the PE.

Aggregation and Core:These terms are not specific to MPLS VPN architecture. "Aggregation" refers to a general networking concept, and "Core" is too broad to describe a specific role in MPLS VPNs.

Conclusion:The correct roles in MPLS VPN architecture are PE, P, and CE.

Which of the following protocols operate at the network layer? (Select All that Apply)

  1. IPv6
  2. ICMPv6
  3. IPv4
  4. OSPF
  5. ICMP

Answer(s): A,B,C,E

Explanation:

Understanding the Network Layer:

The network layer (Layer 3 of the OSI model) is responsible for end-to-end packet delivery, including routing and addressing. Protocols operating at this layer handle logical addressing and path determination.

Explanation of Each Protocol:

IPv6:The next-generation Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

ICMPv6:Internet Control Message Protocol version 6, used for error reporting and diagnostic functions in IPv6 networks. It operates at the network layer.

IPv4:The current widely-used Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

OSPF:Open Shortest Path First is a dynamic routing protocol that operates at the network layer to exchange routing information between routers.

ICMP:Internet Control Message Protocol, used for error reporting and diagnostic functions in IPv4 networks. It operates at the network layer.

Conclusion:IPv6, ICMPv6, IPv4, and ICMP all operate at the network layer. OSPF is also correct because it is a routing protocol that works at Layer 3.

Huawei CloudCampus 3.0 solution implements a fully-wireless intelligent cloud campus network, inspiring digital innovation.
Which of the following benefits description of Huawei CloudCampus 3.0 solution is not correct?

  1. One global network: 40% lower private line costs
  2. L3 autonomous driving: 90% fewer complaints
  3. Low-carbon intelligence: 60% smaller energy consumption of the entire network
  4. Fully-wireless experience: 40% higher productivity

Answer(s): C

Explanation:

Overview of Huawei CloudCampus 3.0:

Huawei CloudCampus 3.0 is designed to provide a fully-wireless, intelligent, and cloud-based campus network solution. It focuses on improving efficiency, reducing costs, and enabling digital transformation.

Analyzing Each Option:

Option A:"One global network: 40% lower private line costs" is correct. Huawei CloudCampus 3.0

reduces private line costs by leveraging cloud-based technologies and SD-WAN solutions.

Option B:"L3 autonomous driving: 90% fewer complaints" is correct. The solution uses AI-driven automation to minimize network issues and improve user satisfaction.

Option C:"Low-carbon intelligence: 60% smaller energy consumption of the entire network" isnot correct.
While Huawei emphasizes energy efficiency, the claim of a 60% reduction in energy consumption is exaggerated and not supported by official documentation.

Option D:"Fully-wireless experience: 40% higher productivity" is correct. The fully-wireless architecture enhances user experience and productivity.

Conclusion:The incorrect benefit description is Option C.
