Course Outline

The CompTIA CloudNetX (CNX-001) Exam covers the following topics -

1. Network Architecture Design (31%)

• Analyze business requirements to apply core networking concepts including OSI layers, IPv4/IPv6, CIDR/VLSM, NAT/PAT, dynamic/static routing, DHCP, DNS (including secure variants like DNSSEC, DoT, DoH), container networking, and more.
• Select and implement network topologies like mesh, star, spine-and-leaf, hub-and-spoke, and point-to-point, along with segmentation techniques (VLAN, VXLAN) and traffic flow considerations (north south, east west).
• Design hybrid connectivity solutions using VPNs, MPLS, SD-WAN, ExpressRoute/Direct Connect, remote access methods, VPC peering, transit gateways, and more.
• Recommend availability solutions: load balancing (global/local, round robin, weighted methods), autoscaling, CDNs, high availability (active-active/passive), link aggregation, and redundancy strategies.
• Evaluate campus installation needs, including power/UPS, environmental controls, fire suppression, physical access controls, and wired/wireless network component selection.

2. Network Security (28%)

• Identifying threats like DDoS, on path attacks, IP spoofing, social engineering, BGP hijacking; addressing vulnerabilities such as zero day exploits, misconfigurations, legacy ACLs, and insecure protocols.
• Implementing mitigations: DLP, IPAM, patch management, CIS benchmarks, and applying frameworks like MITRE ATT&CK and Cloud Controls Matrix (CCM).
• Deploying security technologies including NGFWs, cloud-native firewalls, WAFs, IPS/IDS, encryption and TLS/SSL inspection, application gateways, NAC, and secure web gateways.
• Applying access control measures: firewall rules, NACLs, network security groups, geofencing, URL filtering, and DLP controls.
• Implementing Zero Trust principles: microsegmentation, SASE, CASB, identity-based segmentation, and least privilege.
• IAM techniques: SSO/Federation (SAML, OAuth, OIDC), MFA, PAM, conditional access, PKI, certificates, session tokens, CIEM, and UEBA.
• Securing wireless networks with WPA2/3, TKIP, PSK variants, guest access, captive portals, and MAC filtering.
• • Hardening appliances via patching, disabling unneeded services, credential management, secure configurations, and logging best practices.

3. Network Operations, Monitoring & Performance (16%)

• Managing continuity, risk (acceptance, mitigation, registers), disaster recovery, and service-level agreements (SLAs, SLOs, OLAs, etc.).
• Implementing NFV, reverse/forward proxies, and managing OpEx vs. CapEx models, along with cost optimization and chargeback strategies.
• Using monitoring tools: log collection (SIEM, Syslog), telemetry, SNMP, metrics, dashboards, alerting, QoS, and continuous monitoring for utilization and performance.
• Automating environments using IaC (YAML, JSON), version control, patching, mutable vs. immutable infrastructure, baselines, GitOps, API/CLI usage, SDKs, and generative AI.

4. Network Troubleshooting (25%)

• Applying structured methodologies: identifying problems, forming theories, testing, resolution, validation, and documentation.
• Using tools like Wireshark, Netcat, Nmap, Iperf, OpenSSL, Postman, tcpdump, dig, mtr, ping, traceroute, netstat, curl, and others.
• Troubleshooting connectivity: DNS, asymmetric routing, VLAN misconfigurations, IP/MAC conflicts, NAT table exhaustion, DHCP issues, and BGP faults.
• Addressing performance issues: latency, packet loss, MTU mismatches, fragmentation, broadcast storms, bandwidth constraints, and network scanning delays.
• Investigating Wi-Fi problems: interference, low signal strength, channel overlap, sticky clients, roaming issues.
• Resolving access/security issues: misconfigured rules, DDoS, authentication failures, certificate issues, and traffic drops.
