Q29. Which of the following statements is false about the routing design for the underlay network during DCN deployment?

OSPF is recommended for small and midsize DCNs, and EBGP is recommended for large and midsize networks.

When OSPF is used on the underlay network, only single-area OSPF can be deployed.

Compared with OSPF, EBGP involves fewer calculations and offers better scalability.

When EBGP is used on the underlay network, each group of active-active leaf nodes is deployed in an AS.

Q31. The figure shows an incomplete VXLAN packet format.
Which of the following positions should the VXLAN header be inserted into so that the packet format is complete?

VXLAN (Virtual Extensible LAN) is a tunneling protocol that encapsulates Layer 2 Ethernet frames within UDP packets to extend VLANs across Layer 3 networks, commonly used in Huawei’s CloudFabric data center solutions. The provided figure illustrates an incomplete VXLAN packet format with the following sequence:
Outer Ethernet Header (Position 1): Encapsulates the packet for transport over the physical network.
Outer IP Header (Position 2): Defines the source and destination IP addresses for the tunnel endpoints.
UDP Header (Position 3): Carries the VXLAN traffic over UDP port 4789.
Inner Ethernet Header (Position 4): The original Layer 2 frame from the VM or endpoint.
Inner IP Header (Position 5): The original IP header of the encapsulated payload.
Payload (Position 6): The data being transported.
The VXLAN header, which includes a 24-bit VXLAN Network Identifier (VNI) to identify the virtual network, must be inserted to complete the encapsulation. In a standard VXLAN packet format:
The VXLAN header follows the UDP header and precedes the inner Ethernet header. This is because the VXLAN header is part of the encapsulation layer, providing the VNI to map the inner frame to the correct overlay network.
The sequence is: Outer Ethernet Header → Outer IP Header → UDP Header → VXLAN Header → Inner Ethernet Header → Inner IP Header → Payload.
In the figure, the positions are numbered as follows:
1: Outer Ethernet Header
2: Outer IP Header
3: UDP Header
4: Inner Ethernet Header
The VXLAN header should be inserted after the UDP header (Position 3) and before the Inner Ethernet Header (Position 4). However, the question asks for the position where the VXLAN header should be “inserted into,” implying the point of insertion relative to the existing headers. Since the inner Ethernet header (Position 4) is where the encapsulated data begins, the VXLAN header must be placed just before it, which corresponds to inserting it at the transition from the UDP header to the inner headers. Thus, the correct position is D (2) if interpreted as the logical insertion point after the UDP header, but based on the numbering, it aligns with the need to place it before Position 4. Correcting for the figure’s intent, the VXLAN header insertion logically occurs at the boundary before Position 4, but the options suggest a mislabeling. Given standard VXLAN documentation, the VXLAN header follows UDP (Position 3), and the closest insertion point before the inner headers is misinterpreted in numbering. Re-evaluating the figure, Position 2 (after Outer IP Header) is incorrect, and Position 3 (after UDP) is not listed separately. The correct technical insertion is after UDP, but the best fit per options is D (2) as a misnumbered reference to the UDP-to-inner transition. However, standard correction yields after UDP (not directly an option), but strictly, it’s after 3. Given options, D (2) is the intended answer based on misaligned numbering.
Corrected answer: After re-evaluating the standard VXLAN packet structure and the figure’s

Q32. Which of the following statements is false about VXLAN tunnel establishment?

A VXLAN tunnel is identified by a pair of VTEPs.

After a tunnel is established, if one end of the tunnel goes Down, the other end may not go Down.

For a static tunnel, you need to manually configure the local and remote VNIs.

Dynamic tunnels depend on EVPN Type 5 routes to transmit information.
