This AZ-500 practice question tests your understanding of secure networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Azure Bastion to provide secure RDP and SSH access to Azure VMs without public IPs. Recently, a security audit recommended logging all connections to Bastion. What should you enable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Diagnostic settings on the Bastion resource to stream Bastion logs to a Log Analytics workspace
Azure Bastion integrates with Azure Diagnostic Logs to capture connection logs. Enabling diagnostic settings on the Bastion resource sends logs to a Log Analytics workspace, Storage account, or Event Hub.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Monitor alerts for Bastion resource health
Why it's wrong here
Alerts notify on health issues, not logging connections.
✗
Azure Activity Logs for the Bastion resource
Why it's wrong here
Activity Logs record control plane operations, not data plane connections like RDP/SSH sessions.
✗
Network Security Group flow logs on the subnet containing Bastion
Why it's wrong here
NSG flow logs capture IP traffic, not Bastion-specific connection events.
✓
Diagnostic settings on the Bastion resource to stream Bastion logs to a Log Analytics workspace
Why this is correct
Diagnostic settings enable collection of Bastion diagnostic logs, including connection events.
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.
Detailed technical explanation
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.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
