220-1202 Practice Test 40 — 15 Questions

Question 1

A technician is troubleshooting a server that repeatedly trips the circuit breaker in the data center. The server is plugged into a power strip that is also serving two other high-power devices. What is the most appropriate safety and troubleshooting step?

Accepted Answer

Move one of the other high-power devices to a different circuit and plug the server directly into a wall outlet on its own circuit.. The repeated tripping indicates the circuit is overloaded. The safest and most effective step is to redistribute the load by moving one high-power device to a different circuit and plugging the server directly into a dedicated wall outlet. This isolates the server's power draw and prevents overloading the shared circuit, addressing the root cause without bypassing safety limits.

Answer

Replace the power strip with a higher-rated one and reset the breaker.

Answer

Reset the breaker and use a UPS with a higher wattage rating.

Answer

Install a larger circuit breaker in the panel to handle the load.

Question 2

During a network upgrade, a technician needs to dispose of several old CRT monitors. Which disposal method complies with environmental regulations?

Accepted Answer

Take them to an e-waste recycling center.. CRT monitors contain hazardous materials like lead, phosphorus, and other heavy metals that require specialized handling. Taking them to an e-waste recycling center ensures compliance with environmental regulations such as the Resource Conservation and Recovery Act (RCRA) and local e-waste laws, as these facilities are equipped to safely dismantle and recycle the toxic components.

Answer

Place them in the regular dumpster for pickup.

Answer

Sell them to a scrap metal dealer.

Answer

Remove the glass and dispose of the plastic casing separately.

Question 3

A technician is troubleshooting an iPhone that repeatedly prompts for the Apple ID password even after entering it correctly. The device is not connected to any corporate MDM. What is the most likely cause?

Accepted Answer

iCloud Keychain is out of sync and needs to be reset by signing out of iCloud and back in.. Option C is correct because repeated Apple ID password prompts, even after correct entry, are typically caused by an iCloud Keychain sync conflict. When iCloud Keychain becomes out of sync—often after a password change or device restore—the authentication token chain breaks, forcing the device to re-request the password. Signing out of iCloud and back in resets the local Keychain state and re-establishes a trusted sync relationship with Apple's servers.

Answer

The device is jailbroken and has a tweak interfering with authentication.

Answer

The Apple ID password was changed recently and not synced to all services.

Answer

The device has a hardware fault in the secure enclave.

Question 4

A technician is documenting a configuration change to a firewall rule that allows remote access for a new employee. The technician must ensure the documentation is clear for future audits. Which of the following is the most critical piece of information to include?

Accepted Answer

The business justification for the rule.. Option C is correct because change management documentation must include the business justification to demonstrate that the change was authorized and necessary. Without a clear reason, auditors cannot verify that the firewall rule complies with organizational security policy or regulatory requirements. The business justification provides the context needed to distinguish legitimate changes from unauthorized or malicious modifications.

Answer

The exact date and time the rule was added.

Answer

The IP address of the new employee's remote location.

Answer

The name of the technician who made the change.

Question 5

A technician is setting up a new workstation in a cubicle. The cubicle has multiple power strips daisy-chained together to provide enough outlets. What is the correct safety action the technician should take?

Accepted Answer

Remove the daisy chain and plug each device directly into a wall outlet using a single power strip with surge protection.. Daisy-chaining power strips is a fire hazard because it can exceed the ampacity of the circuit, leading to overheating and potential electrical fires. The correct safety action is to remove the daisy chain and plug each device directly into a wall outlet, using a single power strip with surge protection to safely distribute power without overloading the circuit.

Answer

Continue using the daisy-chained setup since it is convenient and all strips are rated for 15 amps.

Answer

Replace all power strips with heavy-duty extension cords rated for the total load.

Answer

Install a UPS at the end of the daisy chain to regulate power.

Question 6

A technician is working in a server room and notices a small fire starting in a power strip. What type of fire extinguisher should be used?

Accepted Answer

Class C fire extinguisher (dry chemical).. A small fire in a power strip involves energized electrical equipment. Class C fire extinguishers (dry chemical) are specifically designed for electrical fires because the dry chemical agent is non-conductive, preventing the risk of electric shock. Using a water-based extinguisher (Class A) or CO2 (Class B) on live electrical equipment can cause electrocution or damage, while Class D is for combustible metals.

Answer

Class A fire extinguisher (water).

Answer

Class B fire extinguisher (CO2).

Answer

Class D fire extinguisher (metal).

Question 7

Reset the printer to factory defaults.

Question 9

A technician is troubleshooting a network switch that has stopped working. Upon arrival, the technician notices a strong smell of burnt plastic and sees that the power cable is melted near the connector. What is the most appropriate safety action?

Accepted Answer

Turn off the circuit breaker supplying the outlet.. The strong smell of burnt plastic and melted power cable indicate an electrical fault that could cause a fire or electric shock. Turning off the circuit breaker (Option B) is the most appropriate safety action because it disconnects power at the source, eliminating the risk of arcing or electrocution before any physical contact is made with the damaged equipment.

Answer

Unplug the power cable from the switch.

Answer

Replace the power cable with a new one.

Answer

Spray the cable with a Class C fire extinguisher.

Question 10

A company is upgrading its network switches and has 10 old switches that still work. The local school district has requested donations of working equipment. What should the technician do?

Accepted Answer

Donate the switches to the school district.. Donating the switches to the school district aligns with the principle of reuse, which is the most environmentally responsible option before recycling or disposal. The switches are still functional, so extending their lifecycle reduces e-waste and benefits the community. This practice supports the waste hierarchy: reduce, reuse, recycle.

Answer

Throw the switches in the company dumpster.

Answer

Send the switches to a recycler even though they work.

Answer

Keep the switches in storage indefinitely.

Question 11

During a network upgrade, a technician finds a box of old NICs, cables, and small electronic components that are no longer needed. The company has no formal e-waste policy. What should the technician do?

Accepted Answer

Research local e-waste recycling facilities and present a disposal plan to the manager for approval.. Option C is correct because, in the absence of a formal e-waste policy, the technician must act responsibly by researching local e-waste recycling facilities and presenting a disposal plan to the manager for approval. This aligns with environmental best practices and regulatory compliance, as improper disposal of electronic components can violate local laws and harm the environment. The technician should not unilaterally dispose of or sell the items without management authorization.

Answer

Throw the items in the dumpster since they are small and the company has no policy.

Answer

Store the items indefinitely in a closet until a policy is created.

Answer

Sell the items online as a lot to a recycler.

Question 12

A customer reports that their office printer is emitting a strong, acrid smell and producing distorted prints. The printer uses a fuser unit that has been in service for five years. What should you recommend as the most environmentally responsible action?

Accepted Answer

Replace only the fuser unit and recycle the old one through a certified e-waste recycler.. Option B is correct because the fuser unit is a consumable component that degrades over time, and replacing only the faulty fuser while recycling the old one through a certified e-waste recycler minimizes electronic waste. This approach addresses the root cause (a worn-out fuser) without discarding the entire printer, which would generate unnecessary e-waste and violate environmental best practices.

Answer

Replace the entire printer with a new Energy Star model.

Answer

Continue using the printer until it fails completely.

Answer

Disassemble the printer and dispose of all parts in the general trash.

Question 13

A small office wants to dispose of 20 old CRT monitors. The local landfill does not accept e-waste. Which disposal method is both legal and environmentally responsible?
