Understanding the scope of this certification helps candidates align their preparation strategies with the practical challenges that network engineers face in real-world Azure deployments. It also allows them to focus their learning efforts on troubleshooting and diagnostic techniques rather than basic configuration or deployment processes.

Mastering Network Connectivity Troubleshooting in Azure

Network troubleshooting is one of the most demanding skills assessed in the AZ-720 certification. Azure’s networking architecture consists of multiple interconnected services such as virtual networks, subnets, route tables, network security groups, load balancers, and application gateways. Each of these components can introduce issues if not configured correctly. Therefore, mastering network troubleshooting begins with understanding how these services interact and depend on each other.

When troubleshooting connectivity problems, professionals should start by confirming basic communication paths. This involves verifying IP configurations, testing connectivity with ping or trace tools, and examining network security group rules. Network security groups control inbound and outbound traffic through defined rules that may allow or deny communication between resources. Misconfigured rules often lead to connectivity failures that can be difficult to identify without systematic testing.

Routing is another crucial aspect. Azure uses system routes and user-defined routes to manage how traffic flows between subnets and across networks. An incorrect route can cause packets to be sent to unintended destinations or dropped altogether. Understanding how to interpret route tables and modify them appropriately is essential to restoring connectivity.

Virtual private network gateways and peering connections are commonly used to link separate networks or connect on-premises systems to Azure. Troubleshooting these connections involves validating that the gateways are operational, shared keys are synchronized, and that the correct routing configurations exist on both ends. If the issue persists, examining logs and connection statistics can reveal latency, packet loss, or encryption mismatches that may be disrupting communication.

Another layer of troubleshooting involves network performance optimization. Even if connectivity exists, issues such as high latency or inconsistent throughput can affect user experience. Performance monitoring tools can identify whether the problem lies in the network infrastructure or within the applications themselves. Understanding these diagnostic results helps professionals take corrective actions efficiently.

Managing Security and Access in Troubleshooting Scenarios

Security configuration plays a major role in Azure connectivity. Many issues arise not because of network misconfigurations but because of improperly defined access or security policies. In the AZ-720 exam, candidates are tested on their ability to diagnose and resolve access problems that stem from Azure security mechanisms such as network security groups, application security groups, Azure Firewall, and private endpoints.

One of the common causes of connectivity failure is a restrictive network security rule that blocks legitimate traffic. Troubleshooting such issues involves analyzing inbound and outbound rule priorities and determining which rule is being applied to a specific flow. Azure provides diagnostic tools that show the effective security rules applied to network interfaces, making it easier to pinpoint where traffic is being denied.

Private endpoints are another area where connectivity issues often occur. When resources are configured with private endpoints, they are accessible only within specific virtual networks. If other networks or users cannot connect, it may be due to incorrect DNS configurations or missing network permissions. Checking private endpoint connections and verifying DNS resolution paths helps ensure that services can communicate securely.

Identity-based access control also influences network connectivity. Azure uses role-based access control to manage who can configure and access resources. Misconfigured roles can prevent administrators or applications from performing essential actions. Troubleshooting these issues involves reviewing assigned roles, access scopes, and inherited permissions to ensure that the correct access level is granted.

Firewalls and security appliances can also block or restrict network flows unintentionally. When traffic between applications or services is unexpectedly interrupted, reviewing firewall configurations, checking for outdated policies, and ensuring that logging is enabled for diagnostic analysis can help uncover the cause.

Packet capture helps identify issues such as packet loss, retransmissions, or incorrect port usage. The topology view provides a visual representation of the network, which makes it easier to detect misconfigurations or disconnected components.

Azure Monitor plays a broader role in performance management. It collects metrics, alerts, and logs from all Azure resources, providing a centralized view of system health. By setting up alerts for specific metrics such as latency, dropped connections, or CPU utilization, professionals can detect and address problems before they escalate.

Log Analytics complements these tools by enabling deep analysis through query-based investigation. It aggregates logs from different services, allowing users to identify trends and correlations. For instance, if a web application intermittently loses connectivity, Log Analytics can be used to correlate the timing of these failures with network or resource performance metrics to determine the cause.

A strong understanding of how to use these diagnostic tools not only aids in troubleshooting but also helps in preventive monitoring. By continuously tracking system behavior, professionals can anticipate potential issues and take corrective measures before they impact operations.

Optimizing Application Connectivity and Reliability

Application connectivity forms another critical domain in the AZ-720 certification. Applications often rely on multiple interconnected components such as databases, APIs, storage accounts, and front-end services. A connectivity issue in any of these layers can lead to application downtime.

To troubleshoot application connectivity, start by verifying that all dependent services are reachable and configured correctly. Connection strings should contain accurate parameters such as endpoint URLs, ports, and credentials. Misconfigured connection strings are a common cause of application failures. Checking for typos, outdated configurations, and incorrect authentication methods helps eliminate basic errors before moving to more complex analysis.

Security mechanisms such as virtual network service endpoints and private link connections can restrict application access if configured incorrectly. When troubleshooting, confirm that the necessary permissions are applied to both the source and target services. DNS resolution also plays an essential role. Applications must be able to resolve the hostnames of their target services. Misconfigured DNS records or caching problems can lead to failures even when network connectivity is otherwise healthy.

Load balancers and application gateways are commonly used to distribute traffic and enhance application reliability. Troubleshooting these components requires understanding how rules, probes, and backend pool configurations work together. For example, a misconfigured health probe might mark a healthy backend as unavailable, causing connection failures. Reviewing logs and metrics for backend health, response times, and rule processing provides valuable insights into where adjustments are needed.

Latency and performance degradation are also part of application connectivity challenges. Monitoring response times, analyzing performance counters, and reviewing application logs help identify bottlenecks. Solutions may involve optimizing queries, scaling resources, or revising architecture to reduce dependency on underperforming components.
