A technician is building a new desktop PC and installs a single 16GB DDR4-3200 memory module into slot A1. The system boots and displays 16GB. The technician then adds a second identical 16GB module into slot B1. The system now only shows 16GB total. What is the most likely reason?

A technician is building a new desktop PC and installs a single 16GB DDR4-3200 memory module into slot A1. The system boots and displays 16GB. The technician then adds a second identical 16GB module into slot B1. The system now only shows 16GB total. What is the most likely reason?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

The motherboard does not support dual-channel memory

Even if dual-channel is not supported, both modules should still be detected, and the total memory would be 32GB. The issue is that only 16GB is detected, so this is not the cause.

B

Best answer

The second module is not fully seated

If the module is not fully inserted into the slot, it may not make contact. The technician should remove and reinstall the module, ensuring it clicks into place.

C

Distractor review

The second module is defective

While a defective module is possible, the most common and first thing to check is the physical installation. A defective module would typically cause POST beeps or system instability, not just a reduction in total memory.

D

Distractor review

The modules are installed in the wrong slots for dual-channel

Installing modules in the wrong slots might disable dual-channel mode, but both modules would still be detected and total memory would be 32GB. The scenario shows only 16GB total, so this is incorrect.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Question 1

A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?

Question 2

A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)

Question 3

A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?

Question 4

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Question 5

A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?

Question 6

A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?

FAQ

Questions learners often ask

What does this 220-1101 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: The second module is not fully seated — When a memory module is not fully seated into the slot, it may not make proper contact with the connector pins, causing the system not to detect it. The fact that the system still shows only 16GB indicates that the second module is not being recognized. Reseating the module firmly until the retention clips click into place is the most appropriate next step.
