Network Monitoring and Diagnostics
Monitoring questions test Network Watcher, Connection Monitor, packet capture, flow logs, Azure Monitor for Networks, DDoS protection, and security recommendations.
How to study for AZ-700
Treat each AZ-700 item as a traffic-path problem: trace source, destination, DNS, route, next hop, load balancing, private access, and filtering before choosing.
Core concepts
Concept 1
Network Monitoring and Diagnostics questions test Azure networking design and troubleshooting choices rather than memorized portal paths.
Exam cue: Identify the traffic path, scope, protocol, name resolution behavior, next hop, inspection point, and security control.
Concept 2
The best answer traces traffic from source to destination through addressing, DNS, routing, security, connectivity, and delivery controls.
Exam cue: Choose the Azure networking service that fits reachability, availability, latency, scale, and security requirements.
Concept 3
Eliminate answers that ignore effective routes, name resolution, subnet constraints, private DNS, health probes, or network security boundaries.
Exam cue: Prefer least exposure, private access, validated routes, monitored health, and explicit security policy.
Risk pitfalls and guardrails
Confusing DNS resolution with routing or security filtering.
Guardrail: Avoid answers that confuse DNS with routing, service endpoints with private endpoints, NSGs with firewalls, or layer 4 and layer 7 load balancing.
Opening public access when Private Link, VPN, ExpressRoute, or service endpoints meet the requirement.
Guardrail: Avoid answers that confuse DNS with routing, service endpoints with private endpoints, NSGs with firewalls, or layer 4 and layer 7 load balancing.
Choosing load balancing without matching layer 4, layer 7, regional, global, or DNS-routing behavior.
Guardrail: Avoid answers that confuse DNS with routing, service endpoints with private endpoints, NSGs with firewalls, or layer 4 and layer 7 load balancing.
Memory anchors
Network Watcher
Network Watcher provides tools to monitor, diagnose, and visualize Azure network behavior.
Connection Monitor
Connection Monitor tests reachability, latency, and topology between endpoints.
IP Flow Verify
IP flow verify checks whether a packet is allowed or denied by security rules.
Next Hop
Next hop identifies the route destination selected for traffic from a network interface.
Packet Capture
Packet capture records traffic for detailed network troubleshooting.
Flow Logs
Virtual network flow logs capture IP traffic metadata for network security analysis.
Topology
Network topology visualization shows resource relationships and connectivity.
Azure Monitor for Networks
Azure Monitor for Networks provides health and diagnostics views for network resources.
DDoS Protection
Azure DDoS Protection helps protect public endpoints from distributed denial-of-service attacks.
Secure Score
Microsoft Defender for Cloud Secure Score highlights security recommendations and risk posture.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A VM cannot connect to 10.4.2.7. The engineer wants Azure to identify the selected next hop from the VM NIC. Which Network Watcher tool should be used?
An inbound TCP connection to a VM is denied. Which tool can evaluate the applicable NSG decision for the source, destination, port, and direction?
