2V0-41.24 Question 43
Single answerAn organization is deploying VMware NSX-T Data Center in its environment. The administrator has configured a transport zone and attached it to a transport node group. They are now deciding whether to use a vSphere Distributed Switch (VDS) or an NSX Virtual Distributed Switch (N-VDS) for configuring the transport nodes. Which statement correctly describes the relationship among transport nodes, transport zones, VDS, and N-VDS?
- A
A transport zone determines the logical network scope and can be used with either VDS or N-VDS.
- B
A transport node can connect to multiple transport zones, but only if all transport zones are backed by the same switch type (VDS or N-VDS).
- C
VDS and N-VDS can coexist on the same transport node, but they must be configured for separate transport zones.
- D
N-VDS is required for all NSX-T configurations, as VDS is incompatible with NSX-T transport zones.
Show answer and explanation
Correct answer: B
Explanation
In NSX-T, a transport node represents a physical or virtual device (such as a hypervisor) participating in NSX-T networking. Transport zones define the logical network scope and are associated with a specific switch type (VDS or N-VDS). A transport node can connect to multiple transport zones, but all transport zones must use the same switch type for that node. Mixing VDS and N-VDS on a single transport node is not supported.
- A. Incorrect.
This statement is incorrect. While a transport zone does define the logical network scope, its compatibility depends on the type of switch used for the transport nodes. N-VDS is required in certain scenarios, particularly for NSX-T, whereas VDS is supported in more recent versions of NSX-T.
- B. Correct.
This is correct. A transport node can connect to multiple transport zones, but all transport zones must be backed by the same type of switch (either VDS or N-VDS). Mixing VDS and N-VDS for transport zones on a single transport node is not allowed.
- C. Incorrect.
This statement is incorrect. VDS and N-VDS cannot coexist on the same transport node. A transport node can only use one type of switch (VDS or N-VDS) for all its transport zone configurations.
- D. Incorrect.
This is incorrect. While N-VDS was historically required for NSX-T, VMware now supports VDS as a transport node switch in more recent versions. Therefore, VDS is compatible with certain NSX-T transport zones.
