2V0-41.24 Question 61
Select 3A network administrator is implementing a VMware NSX-T Data Center environment and needs to understand how Geneve encapsulation operates within the environment. Which of the following are true about Geneve encapsulation and its role in tunneling within NSX-T?
- A
Geneve encapsulation supports extensibility by allowing metadata to be included in the encapsulated packets.
- B
Geneve is a proprietary protocol developed exclusively for VMware NSX-T environments.
- C
Geneve encapsulates Layer 2 and Layer 3 traffic over an IP transport network.
- D
Geneve has a fixed header size, which ensures predictable overhead in all scenarios.
- E
Geneve's flexible header design allows for the inclusion of NSX-specific fields required for advanced network virtualization features.
Show answer and explanation
Correct answers: A, C, E
Explanation
Geneve is a modern tunneling protocol used in VMware NSX-T to encapsulate network traffic and enable advanced network virtualization features. It is an open standard that supports extensibility through its flexible header design, allowing for the integration of metadata and NSX-specific fields. Unlike protocols with fixed headers, Geneve's variable header size provides flexibility but can lead to variable overhead. It is not proprietary to VMware, making it a widely adopted standard in the industry.
- A. Correct.
Correct: Geneve supports extensibility as it allows custom metadata to be included in the packet headers, which is crucial for network virtualization use cases.
- B. Incorrect.
Incorrect: Geneve is an open standard protocol, not proprietary to VMware, and is designed to work across various platforms.
- C. Correct.
Correct: Geneve encapsulates Layer 2 and Layer 3 traffic, enabling it to transport diverse types of network data over an IP network.
- D. Incorrect.
Incorrect: Geneve does not have a fixed header size; its variable header size allows flexibility but can introduce variable overhead.
- E. Correct.
Correct: Geneve's flexible header design is key for supporting NSX-specific features, such as advanced security policies and network segmentation.
