Q1 multiple-choice · default-network What’s the default deployment pattern recommended for a small PhotoRobot studio (1 Control Unit, 1 camera, 1 lighting kit)?
Source: N01 textbook §1 (The default network).
Explanation: The single flat /24 subnet works for ~80 % of studios and is the recommended starting point. Multi-subnet is overhead when no specific pressure justifies it; default to simple. Source manual:
Network Setup .
Q2 multiple-choice · multi-subnet-trigger Which of these signals most strongly indicates a studio has outgrown its single-subnet design?
Source: N01 textbook §1, §2.
Explanation: Single signals alone are often inconclusive. The decision to split subnets needs multiple pressures present — office cross-talk PLUS expanded lighting load is the unambiguous trigger. Single signals deserve monitoring; combined signals deserve action.
Q3 multiple-choice · lighting-isolation Why is lighting most commonly the FIRST subnet to be split off in a multi-subnet studio?
Source: N01 textbook §3 (Lighting subnet isolation).
Explanation: Lighting kits emit continuous low-bandwidth broadcast traffic + burst spikes during strobe sequences. On a flat network, every device CPUs through this broadcast. Isolation contains it. The other answers are inventions.
Q4 multiple-choice · bandwidth-cameras A studio uses 3 RAW-tethered DSLRs. What’s the rough peak burst bandwidth across all three?
Source: N01 textbook §4 (Bandwidth budgeting).
Explanation: RAW tethered DSLRs run ~60 Mbps peak each; 3 × 60 = 180 Mbps. Industrial GigE Vision cameras would change the math drastically (each ~900 Mbps continuous), but DSLRs are bursty + low-average.
Q5 multiple-choice · switch-capacity A studio’s peak LAN traffic estimate is 240 Mbps. Is a 1 Gbps switch sufficient?
Source: N01 textbook §4.
Explanation: 240 Mbps is well under 1 Gbps switch backplane capacity. A 1 Gbps switch handles the workload without special configuration. The studios that need 10 Gbps are GigE Vision industrial setups.
Q6 multiple-choice · warning-signs Locator scan time on a studio has grown from 3 seconds to 12 seconds over six months. What’s the most likely architectural cause?
Source: N01 textbook §5 (Signs the network is at its limit).
Explanation: Locator discovery uses UDP broadcast. Slow scans indicate broadcast packet loss (congestion) or DHCP exhaustion (many “I’m here” packets per scan). Architecture-level signal: device count + lighting kits sharing the subnet has reached its limit. Time to split subnets or expand DHCP scope.
Q7 true-false · locator-cross-subnet Locator discovery on the main subnet automatically discovers Control Units on a separate lighting subnet.
Source: N01 textbook §3.
Explanation: Locator uses broadcast which doesn’t cross subnet boundaries. Multi-subnet studios either run a Locator instance per subnet OR configure CAPP with static IPs for cross-subnet Control Units.
Q8 multiple-choice · documentation What’s the minimum documentation a successor Network Specialist needs to operate a studio’s network?
Source: N01 textbook §6 (Documenting the studio’s network).
Explanation: The three deliverables are the minimum: diagram (visual), IP table (lookup), change log (history). Without any one of these, the next Network Specialist can’t operate effectively. The other answers are necessary for the business but don’t replace the network docs.
Q9 multiple-choice · escalation Which symptom most clearly indicates PhotoRobot Support escalation rather than in-house resolution?
Source: N01 textbook §7 (When to call PhotoRobot).
Explanation: “MAC never appears anywhere” indicates hardware or firmware failure — beyond network. The other symptoms have clear in-house recoveries (scope expansion, WiFi tuning, firewall rule addition).
Q10 multiple-choice · bandwidth-cloud A studio shoots 60 images per session (JPEG, ~10 MB each) and uploads to cloud over a 100 Mbps fiber link. How long does the cloud upload take after the session?
Source: N01 textbook §4 (Cloud bandwidth math).
Explanation: 60 × 10 MB = 600 MB = 4.8 Gb. On 100 Mbps that’s 48 seconds + overhead ≈ 50 seconds. Most studios don’t bottleneck on cloud upload after a session — they only have a problem when uploads compete with active captures, which is solved by deferring uploads.
Q11 multiple-choice · lighting-isolation-rules A studio splits lighting onto its own subnet. What’s the correct firewall rule between main and lighting subnets?
Source: N01 textbook §3.
Explanation: “Allow all” defeats the isolation purpose. “Block all” prevents CAPP from triggering lighting (it can’t reach the lighting subnet). The correct rule allows the SPECIFIC trigger protocols only — preserves isolation, enables trigger workflow.
Q12 multiple-choice · design-defaults The cleanest summary of N01’s architectural philosophy:
Source: N01 closing message + §2.
Explanation: The Network Specialist’s value is knowing when to leave the default alone . Multi-subnet, custom firewall rules, VLANs are real tools — they’re also operational overhead. Add only when pressure justifies; document why. The over-engineered studios suffer more than the under-engineered ones.
