The correct answers are Connection Troubleshoot and IP flow verify. Connection Troubleshoot performs end-to-end connectivity checks from a source VM to a target address, measuring latency, packet loss, and hop-by-hop routing while also identifying whether NSG or firewall rules are blocking the path, making it ideal for diagnosing reachability and flow permission issues. IP flow verify, on the other hand, is a targeted diagnostic that tests a specific 5-tuple flow (source, destination, port, protocol, direction) against applied NSG rules to confirm whether traffic is allowed or denied at the network security level. On the AZ-104 exam, this question tests your ability to distinguish between a broad connectivity test and a granular flow rule check—a common trap is confusing IP flow verify with NSG diagnostics logs. Remember the memory tip: “Connectivity checks the whole road trip; IP flow verify checks the specific tollbooth.”
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which two Network Watcher tools can help you diagnose whether a VM can reach another address and whether a specific flow is allowed or denied? Select two.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Connection troubleshoot
Connection Troubleshoot (A) is correct because it performs end-to-end connectivity checks between a source VM and a target (IP/FQDN/URL), testing latency, packet loss, and hop-by-hop routing. It also identifies whether the connection is blocked by NSG or firewall rules, making it ideal for diagnosing reachability and flow permission issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Connection troubleshoot
Why this is correct
Correct because Connection troubleshoot checks reachability from a source VM to a destination and reports blocking issues.

✓
IP flow verify
Why this is correct
Correct because IP flow verify shows whether a particular five-tuple flow is allowed or denied by NSGs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Packet capture
Why it's wrong here
False because packet capture records traffic for later inspection, but it does not directly answer allow or deny decisions.
✗
Effective routes
Why it's wrong here
False because effective routes shows routing paths, not whether a specific security flow is allowed or denied.
✗
Network topology
Why it's wrong here
False because that is not the specific Network Watcher tool used for end-to-end connectivity testing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Packet capture' with flow analysis, but Packet Capture only records traffic without evaluating Azure's NSG or routing policies, whereas IP Flow Verify explicitly checks rule evaluation.
Trap categories for this question
Command / output trap
False because effective routes shows routing paths, not whether a specific security flow is allowed or denied.
Detailed technical explanation
How to think about this question
Connection Troubleshoot uses the Azure Network Watcher agent to send ICMP, TCP, or HTTP probes from the source VM to the destination, evaluating both routing (via effective routes) and security rules (via NSG flow logs and effective security rules). IP Flow Verify works by querying the Azure fabric controller to simulate a packet's traversal through NSGs and returns whether the flow is allowed or denied based on the 5-tuple (source IP, destination IP, protocol, source port, destination port). Both tools leverage Azure's control plane data rather than relying on in-guest agents, ensuring accuracy even if the VM is unresponsive.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
