2V0-41.24 Question 63
Single answerAn organization is deploying VMware NSX-T Data Center in their environment. The network administrator is tasked with configuring the transport layer to support overlay networking using Geneve encapsulation. Which statement correctly describes the function of Geneve in this scenario?
- A
Geneve encapsulates Layer 2 and Layer 3 traffic into a UDP packet to enable tunneling over an IP network.
- B
Geneve uses TCP as its transport protocol to provide reliable delivery of overlay packets.
- C
Geneve is a proprietary VMware protocol designed specifically for NSX-T environments.
- D
Geneve supports the addition of metadata fields, allowing for extensibility beyond VLAN-based networks.
Show answer and explanation
Correct answer: A
Explanation
Geneve is an industry-standard tunneling protocol that encapsulates Layer 2 and Layer 3 traffic into UDP packets for transport across an IP network. This enables overlay networking in environments like VMware NSX-T. Geneve's primary goal is to provide a flexible, scalable mechanism for network virtualization, with optional extensibility features such as metadata fields.
- A. Correct.
Correct: Geneve encapsulates Layer 2 and Layer 3 traffic into a UDP packet, enabling tunneling over an IP network as part of overlay networking. This is a core function of Geneve in VMware NSX-T environments.
- B. Incorrect.
Incorrect: Geneve uses UDP as its transport protocol, not TCP, because UDP is more suited for low-latency and high-performance scenarios typical of virtualization environments.
- C. Incorrect.
Incorrect: Geneve is not a proprietary VMware protocol. It is an industry-standard tunneling protocol co-developed by VMware, Microsoft, Red Hat, and others.
- D. Incorrect.
Incorrect: While Geneve does support metadata fields for extensibility, this is not its primary function as described in the scenario.
