A technician installs a new high-performance graphics card into a desktop workstation. The card requires two 6-pin PCIe power connectors. The technician connects the appropriate cables from the power supply, but the system fails to POST; the monitor remains black, although all fans spin including the graphics card fans. The technician verifies that the monitor works with another computer and that the card is fully seated in the PCIe x16 slot. Which of the following is the MOST likely cause of the issue?
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.
Best answer
The power supply unit does not have sufficient wattage to support the new graphics card
Correct. Even if the fans spin, the PSU may not supply enough stable power for the card to complete POST, causing a black screen.
Distractor review
The monitor is not compatible with the graphics card's output resolution
Incorrect. The monitor works with another computer, and the default POST resolution is standard. Incompatibility would not prevent POST entirely.
Distractor review
The PCIe slot is damaged or incompatible
Incorrect. PCIe slots are backward compatible, and the card fans spinning indicates it is seated and receiving power from the slot.
Distractor review
The BIOS settings need to be changed to enable the new graphics card
Incorrect. While some BIOS settings may affect boot order, a new graphics card should be detected by default. BIOS changes are not required for POST.
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 power supply unit does not have sufficient wattage to support the new graphics card — If the system has power (fans spin) but doesn't POST after installing a high-end graphics card, the most common cause is that the power supply does not provide enough wattage to support the new card under load. The card may receive enough power to spin fans but not to initialize fully during POST. A faulty monitor or poor seating would cause different symptoms. The PCIe slot is usually compatible if the card fits and is seated, and BIOS settings would not prevent POST at this stage.
