220-1201 Practice Test 8 — 10 Questions

Question 1

A technician is deploying a new thin client in a hospital room. The thin client has a DisplayPort output, but the existing monitor only has a DVI-D input. The technician needs a single cable to connect them without adapters. Which cable type should be used?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

DisplayPort to DVI-D cable. DisplayPort and DVI-D are both digital standards. A DisplayPort to DVI-D cable can directly connect the two, as DisplayPort is compatible with DVI-D signals. No active conversion is needed because both are digital.

Answer

DisplayPort to VGA cable

Answer

HDMI to DVI-D cable

Answer

DVI-D to DVI-D cable

Question 2

A technician is upgrading a client's laptop from 8 GB to 16 GB of RAM. After installing the new module, the laptop powers on but the screen remains black, and the system emits a series of short beeps. What is the most likely issue?

Accepted Answer

The RAM module is not fully seated in the slot.. A series of short beeps on a laptop usually indicates a memory failure, such as incompatible or improperly seated RAM. The most common cause is that the new RAM module is not fully inserted into the slot, causing a poor connection. The technician should reseat the module firmly until it clicks into place.

Answer

The new RAM module is incompatible with the laptop's chipset.

Answer

The laptop's battery is dead.

Answer

The RAM is installed in the wrong orientation.

Question 3

A user reports that their PC sometimes fails to boot, and when it does, they see a message saying 'Memory Management Error.' They have two 4 GB sticks of DDR3 RAM installed. A technician runs Windows Memory Diagnostic and finds errors on one stick. What should the technician do next?

Accepted Answer

Replace the faulty RAM stick with a new one of the same specifications.. Once a memory diagnostic confirms errors on a specific module, the correct next step is to replace the faulty stick. Running the system with faulty RAM can lead to data corruption and crashes. The technician should identify the bad module (often by testing one at a time) and replace it with a compatible module.

Answer

Run a full system restore to fix the memory management error.

Answer

Update the motherboard BIOS to improve memory compatibility.

Answer

Remove both sticks and clean the contacts with a pencil eraser.

Question 4

A user reports that they cannot access a cloud-based CRM application from their office, but they can access it from home. The technician checks the office firewall and finds that outbound HTTPS traffic is allowed. What should the technician investigate next?

Accepted Answer

DNS resolution for the CRM's domain. If outbound HTTPS is allowed, the issue may be with DNS resolution, which can be blocked or misconfigured by the office network. The CRM's domain name might not resolve correctly, preventing the connection. The technician should test DNS resolution for the CRM's URL.

Answer

The user's browser cache

Answer

The cloud provider's service status

Answer

The user's account permissions

Question 5

A server administrator needs to upgrade a critical database server from 64 GB to 128 GB of RAM. The server uses registered ECC DDR4 memory. They have purchased 8 x 16 GB registered ECC modules. When they install them, the server fails to POST with a memory error. The original 64 GB (4 x 16 GB) modules work fine. What is the most likely reason?

Accepted Answer

The new modules have a different number of ranks (e.g., dual-rank vs. single-rank) than the original modules, causing a rank mismatch that the memory controller cannot handle.. Registered (buffered) ECC memory is designed for servers and has specific compatibility requirements, especially regarding the number of ranks per channel and the memory controller's capabilities. The most likely issue is that the new modules are of a different rank (e.g., dual-rank vs. single-rank) or the server's memory controller cannot handle the total number of ranks when all slots are populated. Mixing ranks or exceeding the rank limit per channel can cause POST failures.

Answer

The new RAM modules are not compatible because they are not ECC, while the server requires ECC.

Answer

The server's BIOS needs to be updated to support 128 GB.

Answer

The new modules are not seated properly in the slots.

Question 6

A help desk ticket reports that a user's PC fails to boot and emits a series of long beeps. The system has two 8 GB DDR4 modules installed. What is the most likely cause of this issue?

Accepted Answer

One of the RAM modules is faulty or not seated properly.. Long beeps during POST typically indicate a memory failure, such as a faulty or improperly seated RAM module. This is a common hardware troubleshooting scenario where the beep code points directly to RAM issues. The technician should reseat or replace the RAM modules first.

Answer

The power supply is failing.

Answer

The CPU is overheating.

Answer

The hard drive has failed.

Question 7

A technician is building a new gaming PC and installs two 16 GB DDR5-5600 modules in the correct slots. The system boots and shows 32 GB in the BIOS, but the memory speed is reported as 4800 MHz instead of 5600 MHz. What is the most likely reason for this?

Accepted Answer

XMP or EXPO has not been enabled in the BIOS.. DDR5 modules default to a standard JEDEC speed (often 4800 MHz) for stability. To achieve the rated 5600 MHz, the user must enable XMP (Intel) or EXPO (AMD) in the BIOS, which applies the manufacturer's overclocking profile. This tests knowledge of memory speed configuration beyond plug-and-play.

Answer

The RAM modules are defective and cannot run at their rated speed.

Answer

The motherboard does not support DDR5-5600.

Answer

The RAM is installed in the wrong slots.

Question 8

A user complains that their laptop, which has 8 GB of RAM soldered on the motherboard, is running slowly when multitasking. They ask if they can add more RAM. The laptop has one empty SO-DIMM slot. What is the best recommendation?

Accepted Answer

Recommend adding a SO-DIMM module of the same type and speed as the soldered RAM.. The laptop has a single empty slot, so adding a SO-DIMM module will increase total RAM. However, mixing a soldered module with a SO-DIMM may force single-channel operation, but the capacity gain outweighs this. The technician should recommend adding a compatible DDR4 or DDR5 SO-DIMM (depending on laptop) to improve performance.

Answer

Advise the user to replace the laptop because soldered RAM cannot be upgraded.

Answer

Suggest removing the soldered RAM and replacing it with a larger module.

Answer

Tell the user to install two SO-DIMM modules for dual-channel.

Question 9

A small office manager wants to upgrade the RAM in several identical workstations from 8 GB to 16 GB. The current modules are DDR3-1600. The company has a box of unused DDR3-1333 modules from an older system. Can they use these modules to upgrade the workstations?

Accepted Answer

Yes, they can add the DDR3-1333 modules, but all RAM will run at 1333 MHz.. DDR3-1333 and DDR3-1600 are both DDR3, so they are physically compatible. However, mixing speeds forces all modules to run at the slower 1333 MHz, which may slightly reduce performance. The upgrade is possible but not optimal.

Answer

No, because the speeds are different and will cause system instability.

Answer

Yes, but only if they replace the existing modules entirely with the DDR3-1333 modules.

Answer

No, because DDR3-1333 is not compatible with DDR3-1600 slots.

Question 10

A technician is troubleshooting a workstation that randomly crashes and shows memory errors in Windows. The system has four 4 GB DDR4 modules. The technician runs Memtest86 and finds errors in one module. What should the technician do to resolve the issue while maximizing performance?

Accepted Answer

Replace the faulty module with a new module of the same specifications.. The faulty module should be removed, but to maintain dual-channel performance, the remaining modules should be installed in matched pairs. Removing one module leaves three, which may force single-channel operation. The best solution is to replace the faulty module with a matching one, but if not available, removing two modules to keep a matched pair is optimal.

Answer

Remove the faulty module and leave the other three installed.

Answer

Remove all modules and install a single 16 GB module.

Answer

Remove the faulty module and the module in the same channel to keep dual-channel.
