A technician is upgrading a desktop computer's memory from 16GB (2x8GB) to 32GB (2x16GB). The technician purchases two 16GB DDR4-3200 modules from the same manufacturer and installs them in the recommended dual-channel slots (A2, B2). The system boots normally and reports 32GB. However, after running a memory-intensive application, the system crashes with a "MEMORY_MANAGEMENT" error. A memory diagnostic tool reports multiple errors at address ranges. The technician checks the BIOS and sees the memory is running at 3200MHz. The CPU is an Intel Core i7-10700K, which officially supports DDR4-2933. What is the most likely cause of the errors?
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 RAM modules are not compatible with the motherboard.
The system boots and reports 32GB, so the modules are recognized and compatible. Incompatibility would typically prevent booting or cause immediate issues.
B
Best answer
The CPU's memory controller is not rated for DDR4-3200, causing instability when XMP is enabled.
The i7-10700K's official memory support is DDR4-2933. The RAM is running at 3200MHz via XMP, overclocking the memory controller and leading to errors under load.
C
Distractor review
The RAM is installed in the wrong slots for dual-channel operation.
Slots A2 and B2 are commonly the recommended slots for dual-channel, so this is likely correct.
D
Distractor review
The power supply unit is providing insufficient voltage to the RAM.
RAM voltage is regulated by the motherboard, not the PSU directly. Insufficient PSU power would more likely cause system crashes under load, but the specific symptom of memory errors points to memory controller or module issues.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: The CPU's memory controller is not rated for DDR4-3200, causing instability when XMP is enabled. — The Intel Core i7-10700K officially supports DDR4-2933 memory speed. Running the RAM at 3200MHz (likely via XMP) overclocks the memory controller beyond its rated specification, which can cause instability and memory errors. The modules are compatible with the motherboard, but the CPU's memory controller may not reliably handle the higher frequency. Other options: A is not likely if the system boots; C is false because A2/B2 is typical for dual-channel; D is unlikely as voltage for RAM is regulated by the motherboard.
