Network Exam Practice Skill

Create and grade computer networking practice that matches the user's materials and exam goal. Favor original questions aligned to concepts instead of copying real exams.

When To Use

Use this skill for:

• final exam review for computer networks;
• 408/考研网络基础练习;
• chapter quizzes and mixed practice;
• subnetting/CIDR calculation, routing table lookup, TCP sequence/ACK, sliding window, congestion control, DNS/HTTP/TLS/DHCP analysis;
• grading user answers and diagnosing weak points.

Question Types

Use a mix based on the user's goal:

• single choice / multiple choice;
• fill in the blank;
• short explanation;
• calculation: subnet, throughput, delay, window size, RTT, sequence number;
• table analysis: routing table, switching MAC table, firewall rule order;
• protocol sequence: TCP, DHCP, TLS, DNS;
• capture interpretation from packet summaries.

Difficulty Bands

• Foundation: definitions, layer mapping, simple packet flow.
• Standard: compare protocols, calculate subnet/routing/window, explain fields.
• Advanced: multi-step integrated problems, error diagnosis, protocol tradeoffs.

Rules

• If the user provides slides, syllabus, notes, assignments, or past questions, use them as the primary scope.
• Do not claim generated questions are real past exam questions unless the user provided them and asks for extraction.
• For current exam formats or official syllabus details, use web search when available and mark assumptions clearly.
• Hide answers first when the user wants simulation or self-test.

Coordination

• Use computer-network-learning before practice if the user lacks prerequisites.
• Use network-protocol-viz after a protocol question if a visual explanation would resolve confusion.
• Use network-packet-lab for capture-based or lab-report questions.
