A technician is assembling a new gaming PC with an AMD Ryzen 5 5600X CPU and a B550 motherboard. After installing the CPU, two DDR4-3600 RAM sticks in slots A2 and B2 (as per manual), and a dedicated GPU, the system powers on but there is no display. The motherboard's CPU debug LED remains lit. The technician has reseated the CPU and checked for bent pins (none found). The PSU is a known-good 650W unit and all fans spin. Which of the following is the MOST likely cause?
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
A. The RAM is not on the motherboard's Qualified Vendor List (QVL).
While using RAM not on the QVL can cause instability, it would typically result in a DRAM debug LED, not a CPU debug LED. The system would still likely attempt to POST.
B
Best answer
B. The motherboard's BIOS needs to be updated to support the Ryzen 5 5600X.
Many B550 boards require a BIOS update to be compatible with Ryzen 5000 series CPUs. A CPU debug LED often indicates this issue.
C
Distractor review
C. The CPU cooler is mounted too tightly, causing pressure on the socket.
Excessive pressure could cause damage, but it is less likely than a BIOS incompatibility. Also, the CPU debug LED would not necessarily be the primary indicator.
D
Distractor review
D. The PCIe power cable for the graphics card is not connected.
If the GPU lacked power, a VGA debug LED would typically illuminate, not a CPU LED. The system might still power on fans but produce no display.
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: B. The motherboard's BIOS needs to be updated to support the Ryzen 5 5600X. — B550 motherboards were released before Ryzen 5000 series CPUs. Many require a BIOS update to support the newer processors. The CPU debug LED indicates a problem with the CPU detection or initialization. RAM compatibility issues would typically light the DRAM debug LED, not the CPU LED. An overtightened CPU cooler could cause socket damage but is less common than a BIOS incompatibility. Missing PCIe power for the GPU would light the VGA debug LED. Therefore, updating the BIOS is the most likely solution.
