A technician upgrades a workstation's memory. The motherboard has four DIMM slots and supports dual-channel DDR4 memory. Two 8 GB DDR4-3200 modules are installed in slots A1 and B1. The system boots, detects 16 GB of RAM, but reports the memory speed at 2133 MHz. Which step should the technician take to achieve the rated speed of 3200 MHz?
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.
Distractor review
Install the modules in slots A1 and A2 instead
Moving the modules to A1 and A2 would put them in a single-channel configuration, which may slightly reduce performance but will not increase speed.
Best answer
Enable XMP/DOCP in the BIOS
XMP (Intel) or DOCP (AMD) profiles allow the memory to run at its rated speed and timings. Enabling this in BIOS will set the memory to 3200 MHz.
Distractor review
Replace the modules with DDR4-2666
Lower-speed modules would not improve performance; the goal is to reach 3200 MHz, not reduce speed.
Distractor review
Update the motherboard chipset drivers
Chipset drivers do not control memory speed; memory frequency is set in BIOS/UEFI firmware.
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: Enable XMP/DOCP in the BIOS — DDR4 memory defaults to a standard JEDEC speed (often 2133 MHz) for compatibility. To run at the rated higher speed (3200 MHz), the technician must enable the memory's XMP (Extreme Memory Profile) or DOCP (Direct Overclock Profile) in the BIOS. This configures the correct timings and voltage. Installing modules in different slots (A1 and A2) would still be single-channel and not affect speed. Replacing with lower-speed modules would not help. Updating chipset drivers does not change memory speed settings, which are controlled by the BIOS.
