HYBRID / OUTSIDE OF CLASS

Your independent work

Due Sunday, January 31, 2027 at midnight, end of day.
The submission window ends Monday, February 1 at 12:00 AM America/Chicago. Monday class → following Sunday deadline.

1. Foundation practice — every week

Complete at least 45 foundation-level questions across assigned licensed lesson checks and an instructor-approved practice set. Identify the source, question count, result and corrections for three weak concepts. Clearly label remediation reattempts; these do not represent 45 unseen vendor questions. A dedicated MeasureUp product for this foundation course has not been verified; Network+ or Security+ practice is not automatically required.

2. Approved remote labs — graded assignments

Your weekly remote-lab portfolio is graded within the 20% lab category. The instructor assesses the work and evidence for each assigned lab; completion alone is not full credit.

Complete every approved remote-lab title assigned to this week. More than one lab may be required when several titles match the chapter material. Plan the assigned NETLAB work for the weekend after class. Reserve lab time early and allow time to troubleshoot, repeat steps and document results. Submit a remote-lab portfolio with a separate section and completion evidence for each assigned title.

Chapter/topic matching keywords: campus network OSI topology segmentation access. Only instructor-approved title matches below are assigned. If none are listed, the catalog match is pending; do not assume that an unrelated lab satisfies the requirement.

Beginner lab candidates — approval pending

OSI Model and Encapsulation Concepts (campus network roles and boundaries)

These are instructor-scoped supplements from the available NDG networking/security libraries, not a verified dedicated a+ Network or a+ Cyber lab package. The instructor must approve installed access, difficulty and exact topic match. Licensed course labs may be assigned instead; submit each exact title in the graded remote-lab portfolio.

3. Reinforcement and reflection

Complete a minimum of 45 foundation-level review questions across instructor-assigned lesson checks and an approved practice set. Record count, source/lesson, results and corrections for three weak concepts. Reattempts are allowed only after explaining the correction and must be identified; 45 questions does not imply 45 unseen vendor questions. No dedicated MeasureUp product for CompTIA a+ Cyber has been verified. A Network+ or Security+ practice test is not automatically assigned to this beginner course. Complete each approved basic NETLAB+ or licensed course-lab title and submit a separate evidence section for each, including steps, interpreted results, troubleshooting and validation. Candidates: OSI Model and Encapsulation Concepts (campus network roles and boundaries). Instructor must confirm installed access, level and topic scope. Submit a reflection and professional handoff by Sunday at end-of-day midnight. Reading/handouts are due before class; quizzes and classroom labs are supervised. Week 8 also requires the separately scheduled instructor final, not a certification exam.

Time and dedication

CompTIA a+ Cyber is one eight-week beginner foundation block. Plan 6–9 hours of independent reading, lesson review, handouts, practice questions, lab evidence and remediation weekly, plus the three-hour meeting (9–12 total). This college-style example expands the vendor's core topics with supervised practice and professional documentation; the estimate is not a vendor duration or a college credit-hour determination. No prior networking or cybersecurity job experience is assumed, but basic computer use and reliable access to the authorized lab environment are needed. Read before class, spread practice across the week and reserve weekend lab time. Taking both foundation examples at once would mean 18–24 total hours weekly and requires a conflict-free schedule arranged by the instructor.

IN CLASS ONLY / 5:45–8:45 PM

Prepare → Quiz → Chapter labs → Closeout

5:45–6:00 · Start-of-class quiz

Take the reading quiz at the beginning of class. Answer each prompt with a technical explanation; prompts are equally weighted.

Identify a campus network component; explain a trust boundary; distinguish connectivity from authorization.

Use your preparation to explain the answer and the reason for it. Review missed concepts during closeout and add corrections to your study notes.

6:00–8:10 · Foundation lab workshop

This module currently has 2 lab activities, approximately 60 minutes each, excluding the 7:00–7:10 break. The instructor may scope the tasks and demonstrations to fit the session. Weeks may use one extended lab, two standard labs, or three to four short chapter activities.

Lab 1

Annotate a fictional campus diagram with clients, switches, routers, wireless and shared services. Identify data paths and an appropriate trust boundary.

Identify the support request, required outcome, authorized environment and safety or rollback precautions.
Record the starting configuration and symptoms. Predict the expected result before changing anything.
Perform the assigned procedure, capture relevant commands or settings, and troubleshoot unexpected results.
Verify the outcome with a repeatable test. Submit your observations, evidence, explanation and a concise service handoff.

Lab 2

Compare allowed and denied client paths in an isolated topology or supplied evidence. Explain why an access boundary exists and document a misconfiguration for escalation.

Identify the support request, required outcome, authorized environment and safety or rollback precautions.
Record the starting configuration and symptoms. Predict the expected result before changing anything.
Perform the assigned procedure, capture relevant commands or settings, and troubleshoot unexpected results.
Verify the outcome with a repeatable test. Submit your observations, evidence, explanation and a concise service handoff.

This is an original provisional sequence. Confirm chapter alignment and lab scope against the licensed text; the exact textbook lab sequence has not been extracted. In-class lab work and its evidence are completed in the supervised class period, not assigned as weekend hybrid work.

8:10–8:45 · Closeout lecture, Q&A and announcements

Debrief campus networks and security boundaries: explain one result, correct missed concepts, connect the activity to CompTIA Security+ readiness, answer questions and confirm next reading and Sunday deadline.

Connect lab results to certification concepts, resolve questions, review common errors, and confirm announcements, next week's reading and the hybrid deadline. Any make-up arrangements require instructor approval.
