Mixed Deck — All CCT Topics Flashcards

A Casper system's circuit breaker trips repeatedly under normal load. Which condition most likely explains this behavior?

Answer: The breaker is faulty, there is a partial ground fault, or the load exceeds the breaker rating

Repeated tripping under normal load indicates either a defective breaker, a partial ground fault drawing extra current, or an actual load that exceeds the breaker's rating.

Which inspection method involves examining a Casper system's connections and mounts visually without energizing the system?

Answer: Pre-energization visual inspection

Pre-energization visual inspection checks physical integrity—connections, mounts, and wiring—before power is applied to prevent damage from assembly errors.

During a routine maintenance window, a technician must verify that all Casper management binaries are current. Which command confirms the installed Jamf binary version?

Answer: jamf -version

Running 'jamf -version' in Terminal outputs the current version of the installed Jamf management binary.

How can hardware failures be detected in a Casper system?

Answer: By running system diagnostics and checking error messages.

Hardware failures often manifest through specific error messages displayed by the operating system or hardware itself, or through unusual system behavior. Running dedicated system diagnostics tools can thoroughly test hardware components like memory, CPU, and storage drives, pinpointing faults. These diagnostic reports and error codes are essential for accurately identifying the failing component and guiding repair efforts.

What does the term 'voltage drop' refer to in a Casper system's supply wiring?

Answer: The reduction in voltage along a conductor due to its resistance and the current flowing through it

Voltage drop is the decrease in electrical potential along a wire caused by the wire's resistance and the current it carries, and excessive drop can impair equipment performance.

Which wire termination method provides the most reliable, vibration-resistant connection in a Casper system subject to mechanical vibration?

Answer: Crimped ring or fork terminal with the correct crimp tool

Properly crimped ring or fork terminals create a gas-tight mechanical connection that resists loosening from vibration far better than other field-termination methods.

After a macOS upgrade, a Casper extension attribute script stops returning data. What is the most likely reason?

Answer: The script's interpreter path changed after the OS upgrade

macOS upgrades can change or relocate interpreter paths (e.g., Python 2 removal), causing scripts that reference old paths to silently fail.

What does a red-tag hold on a Casper component indicate in a quality-control workflow?

Answer: The component is quarantined due to a defect or non-conformance

A red-tag (quarantine tag) signals that the component has failed inspection or is suspected defective and must not be used until disposition is determined.

How can system performance be improved through monitoring?

Answer: By detecting and addressing performance bottlenecks, improving resource allocation.

System monitoring provides crucial data on resource usage, response times, and throughput, which helps pinpoint areas of inefficiency. By analyzing this data, administrators can identify performance bottlenecks, such as overworked CPUs or insufficient memory. This targeted approach allows for optimization of resource allocation or system configurations, ensuring the system runs more efficiently and delivers better performance.

How should Certified Casper Technician professionals handle updated procedures?

Answer: Review updates, complete training, implement revisions

Staying current with procedural updates is a professional obligation.

How does installation at high altitude affect Casper pneumatic tube system performance?

Answer: Reduced air density at altitude requires increased blower capacity to maintain performance

At higher altitudes, lower air density reduces the pressure differential a given blower can generate, requiring larger or faster blowers to compensate.

A technician notices that smart card authentication is failing after a Casper enrollment. Which component should be checked first?

Answer: The device's certificate trust store

Smart card authentication relies on certificate trust chains, so a missing or expired certificate in the trust store is the most common failure point.

What is the CORRECT sequence when performing a Certified Casper Technician technical procedure?

Answer: Plan, prepare, execute, verify, and document

This systematic sequence ensures quality and accountability.

A Casper system's software control system logs a 'watchdog timeout' fault. What does this indicate?

Answer: A critical software process failed to respond within the expected time window

A watchdog timeout means a monitored software process stopped responding, indicating a software hang or hardware communication failure requiring system restart and investigation.

Why is it important to verify polarity when connecting DC power to a Casper system control board?

Answer: Connecting DC with reversed polarity can immediately damage or destroy polarity-sensitive components such as ICs, diodes, and capacitors

Many DC components including ICs, electrolytic capacitors, and diodes are polarity-sensitive and will be instantly damaged or destroyed if connected with reversed DC polarity.

What is the first step in setting up the Casper system?

Answer: Ensure hardware installation and connections are correct.

The first step in setting up any hardware-dependent system like Casper is to ensure that all physical components are correctly installed and connected. This foundational step verifies that the system has the necessary hardware in place and that it can communicate effectively. Without correct hardware, subsequent software configuration steps would be impossible or lead to errors.

Which Casper setting controls whether computers are allowed to submit duplicate inventory records to the JSS?

Answer: Recurring Check-In > Enable Recon

The Recurring Check-In settings control whether clients run Recon at each check-in, which determines how frequently inventory is updated and whether duplicates can form.

In a Casper monitoring system, OES (Optical Emission Spectroscopy) data shows a sudden increase in the Si emission line intensity mid-process. This MOST likely indicates:

Answer: A process endpoint has been reached and silicon is being exposed

A rising Si emission signal during etch typically signals that the underlying silicon layer is being exposed, often used as an end-point detection signal.

A Casper device is cycling power unexpectedly every few minutes. What is the most likely root cause?

Answer: Corrupted firmware causing a watchdog timer reset

A watchdog timer reset triggered by corrupted firmware is the most common cause of unexpected repetitive power cycling in Casper devices.

What is the key difference between refrigerant 'recovery,' 'recycling,' and 'reclaiming' as defined by EPA Section 608?

Answer: Recovery removes refrigerant from equipment; recycling cleans it on-site for reuse; reclaiming restores it to ARI 700 purity standards at a certified facility

EPA distinguishes the three: recovery (removing from equipment), recycling (cleaning for on-site reuse), and reclaiming (restoring to ARI 700 virgin purity at a certified reclaimer).
