A. B. C. D. E.

Correct Answer: B

First 31 addresses from the Public VIP Network are reserved by the Azure Stack infrastructure.

The small set of Azure Stack services use 8 public IP addresses while the rest are used by tenant VMs.

Here the subnet mask can vary from smallest /26 (64 hosts) to largest /22 (1022 hosts).

Option A is incorrect.

The largest subnet mask that can be used for the Public VIP Pool is /22 with 1022 hosts, not /20.

Option B is correct.

The largest subnet mask that can be used for the Public VIP Pool is /22 with 1022 hosts.

Option C is incorrect.

/24 is the recommended subnet mask, not the largest one.

Option D is incorrect.

/26 is the smallest subnet mask with 64 hosts.

Option E is incorrect.

The subnet mask can vary from /22 to /26

Therefore, /28 is not the right answer.

When deploying Azure Stack Hub integrated system that will be connected to the internet, it is important to define the public VIP pool. The public VIP pool is a range of IP addresses assigned to the virtual IPs of the Azure Stack Hub. These VIPs are public-facing and allow external users to access the resources hosted on the Azure Stack Hub.

When selecting the subnet mask for the public VIP pool, it is important to consider the number of VIPs required and the available IP addresses in the subnet. The larger the subnet mask, the smaller the number of available IP addresses.

In general, a larger subnet mask provides greater security by reducing the number of available IP addresses that can be accessed from the internet. However, it also limits the number of available VIPs that can be used.

For the public VIP pool, a subnet mask of /24 is the smallest recommended subnet mask. This provides 256 IP addresses and allows for a reasonable number of VIPs to be configured.

The largest subnet mask that should be used for the public VIP pool depends on the number of VIPs required and the available IP addresses in the subnet.

Based on the available options, the largest subnet mask that should be used is /20. This provides 4096 IP addresses and allows for a larger number of VIPs to be configured, while still providing a reasonable level of security.

In summary, the largest subnet mask that should be used for the public VIP pool depends on the number of VIPs required and the available IP addresses in the subnet, but a /20 subnet mask is the largest recommended option from the given choices.
