Full question →hardmultiple choiceObjective-mapped
A technician is building a custom workstation for 3D rendering. The components include an AMD Ryzen 7 5800X CPU, a B550 motherboard (box states 'AMD Ryzen 3000 desktop ready'), two 16GB DDR4-3600 modules (on the QVL), and a dedicated GPU. The system powers on, case fans spin, and the CPU fan spins, but the motherboard’s CPU debug LED remains lit and there is no display. The technician has reseated the CPU and found no bent pins. The RAM and GPU have been verified working in another system. The PSU is a known-good 750W unit. Which of the following should the technician do NEXT?
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
Replace the power supply with a higher-wattage unit
The system powers on and fans spin, indicating the PSU is delivering enough power. A higher wattage PSU would not resolve a CPU recognition issue indicated by the CPU debug LED.
B
Best answer
Upgrade the motherboard BIOS using the BIOS flashback feature
The motherboard likely has an older BIOS that does not support the Ryzen 5000 series CPU. Updating the BIOS to the latest version may enable compatibility and allow the system to POST. Many B550 boards can be updated without a CPU using a USB flash drive and a dedicated button.
C
Distractor review
Test the system with a known-working Ryzen 3000 CPU
While this would confirm whether the CPU is incompatible, it is often not the most practical first step because a technician may not have a spare CPU. A BIOS update is usually easier and faster to perform.
D
Distractor review
Replace the motherboard with a newer model that officially supports Ryzen 5000
Replacing the motherboard is expensive and unnecessary if a BIOS update can resolve the compatibility issue. It should be considered only after updating the BIOS proves unsuccessful.
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: Upgrade the motherboard BIOS using the BIOS flashback feature — The B550 motherboard box indicates it is 'AMD Ryzen 3000 desktop ready,' meaning it was likely manufactured before the Ryzen 5000 series launch and may have an older BIOS that does not support the Ryzen 7 5800X (a Ryzen 5000 series CPU). The CPU debug LED is lit, suggesting the motherboard is not recognizing the CPU. Updating the BIOS to a version that supports Ryzen 5000 is the appropriate next step. Many B550 boards support BIOS flashback, allowing updates without a compatible CPU. Replacing the PSU is unlikely to help since fans spin and other components work. Testing with a different CPU would confirm the issue but may not be practical. Replacing the motherboard is premature before attempting a BIOS update.
