Comprehensive and Detailed Explanation From Exact Extract:

The traceroute shows that the traffic successfully passes through the application development network (192.168.2.1), to the server segment gateway (192.168.1.1), and reaches the serversegment firewall (192.168.4.1). However, it times out immediately after hitting 192.168.4.1, indicating that the traffic is being dropped or filtered at that firewall.

Because other users (outside of the application development segment) are able to SSH into the database server (192.168.1.9), the issue is not with the database server itself or the core network. This points to the server segment firewall blocking traffic originating from the application development subnet (192.168.2.0/24), which is a common practice in segmented network designs unless proper access rules are defined.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Network Segmentation and Firewall Rules”:

“Firewalls between network segments may enforce security policies that restrict access based on source/destination IP and port. Lack of proper allow rules can result in blocked traffic even if routing is successful.”

Other options:

A. The core firewall is not in the traceroute path; it is irrelevant to this specific flow.

B. NSGs (Network Security Groups) apply to cloud workloads, but the behavior and hop-by-hop flow suggest it is a firewall-level issue, not NSG misconfiguration.

D. Bandwidth issues would typically show packet loss or high latency, not consistent timeouts at a specific hop.

Comprehensive and Detailed Explanation From Exact Extract:

NetFlow provides flow-level metadata about IP traffic without requiring inline deployment. It summarizes who is talking to whom, for how long, and how much data was exchanged. It’s ideal for behavior monitoring and threat detection when sent to a SIEM for correlation and analysis.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “NetFlow and Network Telemetry”:

“NetFlow provides visibility into traffic patterns, which can be used for anomaly detection and security analysis when integrated with SIEM platforms.”

Other options:

A. Syslog shows event-level data, but not network behavior.

B. SNMP traps monitor device status, not traffic behavior.

C. SSL decryption is complex and requires inline positioning.

Comprehensive and Detailed Explanation From Exact Extract:

A. Least privilege – This Zero Trust principle ensures users can only access the resources necessary for their job roles. Role-based access control (RBAC), as mentioned in the scenario, is a textbook implementation of least privilege.

C. Microsegmentation – Deploying the application in a small subnet (192.168.77.32/30 provides only 2 usable host IPs) limits lateral movement and isolates the host at a network level. This is a key characteristic of microsegmentation, where resources are placed in small, tightly controlled network segments.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Zero Trust Security Architecture”:

“Least privilege enforces access permissions based on job responsibilities.”

“Microsegmentation applies granular isolation policies between resources to reduce the attack surface and lateral movement.”

Other options:

B. Device trust involves assessing device posture and compliance before granting access.

D. CASB (Cloud Access Security Broker) governs cloud access, not access control or subnetting.

E. WAF protects web applications but is not a Zero Trust element directly related to access control.

F. MFA supports identity verification but is not directly evidenced in the scenario.
