ENWLSI 300-430 study plan

ENWLSI 300-430 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Monitoring and Troubleshooting Cisco Wireless Networks & Implementing a Wireless Network

  • Map the exam blueprint against your current job tasks and write a gap list of at least 10 specific skills you cannot yet perform without documentation

  • Build a lab topology in Cisco DNA Center or a controller-based lab with one WLC, two APs, and a management VLAN, and bring it to a working registered state

  • Practice navigating the controller GUI and CLI to locate client detail, AP detail, and alarm views without searching

  • Capture a baseline of normal AP join, client association, and roaming events in the event log so you can recognize anomalies later

Your checkpoint

A dated gap list plus a working lab topology diagram with screenshots of the registered APs and one associated client

Week 2

Monitoring and Troubleshooting Cisco Wireless Networks

  • Configure and interpret syslog, SNMP traps, and NTP on the controller, then generate a test alarm and confirm it reaches your collector

  • Use controller troubleshooting tools (ping, traceroute, debug client, packet capture) to diagnose a deliberately broken client DHCP flow

  • Read a client detail page and explain each field that would change between a healthy and failing association

  • Diagnose an AP that fails to join by checking licensing, time, certificate, and CAPWAP reachability in order

  • Document a triage checklist that moves from physical/RF to CAPWAP to authentication to policy

Your checkpoint

A written troubleshooting runbook with the commands and GUI paths for five failure scenarios you reproduced

Week 3

Implementing Cisco Wireless Security

  • Configure WPA2-Enterprise with 802.1X against a local RADIUS server and verify a successful and a failed authentication in logs

  • Configure and test a web policy (web authentication) WLAN and explain how it differs from guest portal flows

  • Configure an ACL and a client exclusion policy, then prove exclusion triggers after repeated failed authentications

  • Compare PSK, 802.1X, web policy, and FlexConnect local switching security behavior and note where each breaks

  • Enable and read controller security alarms and attack signatures for management frame protection

Your checkpoint

A security configuration sheet with WLAN-to-policy mappings and captured log evidence for one success and one failure per method

Week 4

Implementing Cisco Wireless Security & Implementing Cisco Wireless Guest Access

  • Deploy a guest WLAN with an anchor controller and verify tunneling of guest client traffic from foreign to anchor

  • Configure a guest portal with guest user accounts, sponsor approval, and a time-limited access policy, then test expiry

  • Apply guest traffic isolation and a guest-specific ACL restricting access to internal subnets

  • Explain and test the difference between centrally switched guest access and FlexConnect local switching guest access

  • Verify guest client VLAN, DHCP, and DNS behavior end to end with packet capture or client detail inspection

Your checkpoint

An end-to-end guest access demo write-up including anchor configuration, portal screenshots, and a capture showing guest traffic exiting the anchor

Week 5

Implementing Cisco Wireless Quality of Service (QoS)

  • Configure QoS profiles and map them to WLANs, then verify the mapping appears on the AP and client

  • Configure AVC or application visibility for a chosen application and confirm classification in the controller

  • Configure and test EDCA/WMM parameters and explain how they affect voice and video clients

  • Configure bandwidth contracts or rate limiting on a WLAN and measure the effect with a throughput test

  • Trace a packet through the QoS pipeline from wireless client to wired uplink and identify each marking point

Your checkpoint

A QoS design table mapping application class to QoS profile, DSCP, and WLAN, with measured before/after throughput results

Week 6

Implementing Cisco Wireless High Availability and Mobility & Implementing and Configuring Cisco Wireless Multicast and mDNS

  • Configure an HA pair (or N+1 with a backup controller) and verify AP and client failover by disabling the primary

  • Configure mobility groups between two controllers and test client roaming with a documented roam event

  • Configure multicast on the controller for a video stream and verify IGMP snooping and multicast-direct behavior

  • Enable mDNS snooping and a service policy so a Bonjour printer or AirPlay service is discoverable across VLANs

  • Test and document a FlexConnect local switching setup with local auth and central DHCP

Your checkpoint

A failover and roaming test report with timestamps, roam counts, and mDNS service discovery evidence across subnets

Week 7

Implementing a Wireless Network & Monitoring and Troubleshooting Cisco Wireless Networks

  • Design and implement a full WLAN from a written scenario covering SSIDs, VLANs, security, QoS, and guest access without referring to notes

  • Use Prime Infrastructure or DNA Center to run a report and interpret client health and AP performance metrics

  • Perform RF validation with a site survey tool and identify at least three coverage or interference issues in your lab or a simulated dataset

  • Tune RRM, channel width, and transmit power and measure the change in client experience

  • Re-run your week 2 runbook against a new injected fault and record whether the checklist held

Your checkpoint

A complete design-and-build document for the scenario plus an RF validation report with three findings and remediations

Week 8

Implementing a Wireless Network & Implementing Cisco Wireless Guest Access & Implementing Cisco Wireless Security & Implementing Cisco Wireless Quality of Service (QoS) & Implementing and Configuring Cisco Wireless Multicast and mDNS & Implementing Cisco Wireless High Availability and Mobility & Monitoring and Troubleshooting Cisco Wireless Networks

  • Take a timed 60-question practice set weighted by domain percentage and score each domain separately

  • Re-study only the two lowest-scoring domains and rewrite your notes into one-page summaries

  • Re-lab the three configurations you were slowest to build during the practice set

  • Review every missed question and write the underlying fact or procedure it tested

  • Confirm exam-day logistics and finalize a one-page command and GUI-path cheat sheet

Your checkpoint

A scored practice exam report by domain plus a one-page cheat sheet and a list of residual weak areas with a review plan

Milestones

Week 2: You can diagnose an AP join failure and a client DHCP failure from logs alone, without guessing, and your runbook covers both

Week 4: Guest client traffic demonstrably tunnels to the anchor controller and the guest portal enforces account expiry

Week 6: A controller failover and a client roam both complete with documented timestamps, and an mDNS service is discovered across VLANs

Week 8: Practice exam score is at or above your target passing margin, with no domain below 70 percent and a written remediation plan for any that is
