A hub-and-spoke Azure network must centralize outbound inspection and still allow spokes to resolve private endpoint DNS names. Which two components are commonly required? (Choose 2.)
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
Best answer
User-defined routes from spoke subnets to the firewall or NVA.
UDRs steer traffic through the inspection point.
B
Best answer
Private DNS zones linked to the VNets or resolved through a central DNS design.
Private endpoints require correct private DNS resolution.
C
Distractor review
A public IP address on every private endpoint.
Private endpoints use private IP addresses.
D
Distractor review
Basic SKU load balancers in each spoke.
Load balancers are not required for DNS resolution or centralized egress inspection.
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.

FAQ
Questions learners often ask
What does this AZ-305 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: User-defined routes from spoke subnets to the firewall or NVA. — Centralized inspection normally uses UDRs to a firewall/NVA. Private endpoint name resolution requires private DNS zones linked to the relevant VNets or central DNS forwarding.
