Traffic from a spoke VNet must reach the internet through a firewall in the hub VNet. What routing configuration is required on the spoke subnets?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
A route to Internet with next hop Internet
This does not meet the stated requirement as directly as the correct option.
B
Best answer
A default route to the Azure Firewall private IP or virtual appliance next hop
Correct for the stated requirement.
C
Distractor review
An NSG deny rule for 0.0.0.0/0
This does not meet the stated requirement as directly as the correct option.
D
Distractor review
A service endpoint policy
This does not meet the stated requirement as directly as the correct option.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
