Network operations
⏱ ~3-min readAceMark GuideWhat this topic is really about
In active-passive failover, the standby device takes over when the active one fails, providing redundancy. Load balancing distributes traffic across multiple active devices, port aggregation bonds links for bandwidth, and round-robin DNS rotates IPs for crude distribution.
A network diagram (physical and/or logical) maps devices, links, IP schemes, and connections, aiding troubleshooting and planning. An AUP defines acceptable behavior, an SLA defines service guarantees, and a change log records modifications.

VLANs partition one physical switch into multiple Layer 2 broadcast domains. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.
An exam-style question, fully explained
A network admin needs to segment broadcast domains without adding physical hardware. What feature accomplishes this on a managed switch?
- Identify what the question tests: A network admin needs to segment broadcast domains without adding physical hardware..
- VLANs partition one physical switch into multiple Layer 2 broadcast domains.
- Trunking carries multiple VLANs over a single link.
- STP prevents Layer 2 loops.
- Port mirroring copies traffic for analysis.
Traps the examiner sets
- Read each option carefully — distractors on Network operations are designed to look plausible.
- Re-check the exact wording of the question stem before committing to an answer.
- Watch the qualifiers ("always", "only", "except") that flip a correct-looking option.
