Private Network Size

Correct Answer: C

Private network is /20 (4096 IPs) network that is private to the Azure Stack region and does not route beyond the border switch devices of the Azure system.

This network is divided into many subnets like storage network, Internal virtual IP network and Container Network, etc.

Option A is incorrect.

Switch Infrastructure Network is /26 network.

Option B is incorrect.

Azure stack infrastructure Network is /24 network that is dedicated to internal Azure Stack components and allows them to communicate and transfer data among themselves.

Option C is correct.

A private network is a /20 (4096 IPs) network.

Option D is incorrect.

A switch management network is a /29 (six host IPs) network that is dedicated to connecting the management ports of the switches.

In an Azure Stack Hub Integrated System, the private network is used for communication between the infrastructure roles, such as the host, storage, and networking roles. This network is private to the Azure Stack region and does not route beyond the border switch devices of the Azure system.

The size of the private network is determined by the number of nodes in the Azure Stack region. The private network should provide enough IP addresses for all the infrastructure roles and leave room for future growth.

Option A, /26, provides 64 IP addresses, which may not be sufficient for a larger Azure Stack region.

Option B, /24, provides 256 IP addresses, which is usually enough for smaller Azure Stack regions.

Option C, /20, provides 4,096 IP addresses, which is suitable for larger Azure Stack regions.

Option D, /29, provides only 8 IP addresses, which is not enough for any Azure Stack region.

Therefore, the correct answer is option C, /20, as it provides enough IP addresses for larger Azure Stack regions.
