Practice Questions 2026–2027
110 Multiple-Choice Questions • Answers • Detailed Rationales
High-Yield Study Notes
Addressing and segmentation: Plan nonoverlapping CIDR blocks, subnets, private endpoints, peering,
hub-and-spoke topology, and private DNS.
Routing and protection: Understand NSGs, ASGs, user-defined routes, Azure Firewall, WAF, DDoS
mitigation, and Bastion.
Hybrid networks: Contrast VPN Gateway, ExpressRoute, Virtual WAN, BGP, and DNS forwarding.
Traffic distribution: Choose between Load Balancer (L4), Application Gateway (regional L7), Front Door
(global HTTP/S), and Traffic Manager (DNS).
Reliability and observability: Design zone/region redundancy, outbound NAT, monitoring, and network
troubleshooting.

Practice Questions
Scenario Set A — Virtual networking
Question 1. An Azure architect must isolate two application tiers inside one VNet using separate IP
ranges. Which design or service best meets this requirement?
A. Management groups
B. Subnets
C. Availability zones
D. Resource groups
Correct Answer: B. Subnets
Detailed Rationale: Subnets partition VNet address space into separate network segments.
Why the Other Options Are Incorrect: A. Management groups addresses a different networking
function and does not directly meet the stated requirement. C. Availability zones addresses a
different networking function and does not directly meet the stated requirement. D. Resource
groups addresses a different networking function and does not directly meet the stated
requirement.
Question 2. An Azure architect must connect two Azure VNets privately using Microsoft backbone
routing. Which design or service best meets this requirement?
A. Azure DNS public zone
B. Azure Front Door
C. VNet peering
D. Public IP prefix
Correct Answer: C. VNet peering
Detailed Rationale: VNet peering routes private traffic between VNets across Azure backbone.
Why the Other Options Are Incorrect: A. Azure DNS public zone supplies public name resolution,
not the private connectivity or network enforcement required here. B. Azure Front Door is designed

,WGU E033 | AZURE NETWORKING ARCHITECTURE | 2026–2027
for global application/DNS traffic distribution rather than the requested private networking or
regional control. D. Public IP prefix addresses a different networking function and does not directly
meet the stated requirement.
Question 3. An Azure architect must link many branch-connected VNets with centrally managed
routing. Which design or service best meets this requirement?
A. Azure CDN
B. Azure Bastion
C. Azure Policy
D. Azure Virtual WAN
Correct Answer: D. Azure Virtual WAN
Detailed Rationale: Virtual WAN provides managed hub-and-spoke connectivity at scale.
Why the Other Options Are Incorrect: A. Azure CDN addresses a different networking function and
does not directly meet the stated requirement. B. Azure Bastion provides secure VM
administration, not the requested application connectivity or routing function. C. Azure Policy
addresses a different networking function and does not directly meet the stated requirement.
Question 4. An Azure architect must build a central VNet hosting shared firewalls and gateways for
spoke VNets. Which design or service best meets this requirement?
A. Hub-and-spoke topology
B. Flat single-subnet topology
C. Public endpoint-only design
D. Per-VM public IP design
Correct Answer: A. Hub-and-spoke topology
Detailed Rationale: The hub centralizes shared networking services while spokes isolate
workloads.
Why the Other Options Are Incorrect: B. Flat single-subnet topology addresses a different
networking function and does not directly meet the stated requirement. C. Public endpoint-only
design addresses a different networking function and does not directly meet the stated
requirement. D. Per-VM public IP design addresses a different networking function and does not
directly meet the stated requirement.
Question 5. An Azure architect must provide private address resolution for internal virtual
machines. Which design or service best meets this requirement?
A. Azure Front Door

B. Azure DNS Private Resolver with private DNS zones
C. Azure DNS public zone only
D. Azure CDN
Correct Answer: B. Azure DNS Private Resolver with private DNS zones
Detailed Rationale: Private DNS zones resolve private records; Resolver supports hybrid
forwarding.
Why the Other Options Are Incorrect: A. Azure Front Door is designed for global application/DNS
traffic distribution rather than the requested private networking or regional control. C. Azure DNS
public zone only addresses a different networking function and does not directly meet the stated
requirement. D. Azure CDN addresses a different networking function and does not directly meet
the stated requirement.
Question 6. An Azure architect must prevent overlapping private IP ranges when connecting VNets.
Which design or service best meets this requirement?
A. Using only public DNS
B. Disabling route tables
C. Nonoverlapping CIDR address planning
D. Duplicating every subnet range
Correct Answer: C. Nonoverlapping CIDR address planning
Detailed Rationale: Overlapping prefixes create ambiguous routing and complicate peering and
VPNs.
Why the Other Options Are Incorrect: A. Using only public DNS addresses a different networking
function and does not directly meet the stated requirement. B. Disabling route tables addresses a
different networking function and does not directly meet the stated requirement. D. Duplicating
every subnet range addresses a different networking function and does not directly meet the
stated requirement.
Question 7. An Azure architect must allocate a /24 network from a larger /16 address block. Which
design or service best meets this requirement?
A. Application Gateway
B. Azure DDoS Protection
C. Network Watcher
D. CIDR subnetting
Correct Answer: D. CIDR subnetting
