Full question →easymultiple choiceObjective-mapped
A user reports that their Android smartphone can see the corporate Wi-Fi network (SSID: CorpNet) but fails to connect, displaying 'Authentication error'. Other devices on the same network connect successfully. The technician has confirmed the Wi-Fi password is correct and the device is not using a static IP. Which of the following is the BEST first troubleshooting step?
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
Reset the network settings on the phone.
Resetting network settings is a more invasive step that clears all saved networks, paired Bluetooth devices, and VPN configurations. It should be tried only after simpler steps like forgetting the specific network fail.
B
Distractor review
Modify the Wi-Fi security type on the phone to match the router.
While a mismatch could cause an authentication error, the phone likely detected the correct security type automatically. Most modern devices auto-detect the security protocol, so manual change is rarely needed and not the first step.
C
Best answer
'Forget' the network and reconnect by entering the password again.
Forgetting the network removes the saved profile, clearing any corrupt credentials or incorrect security settings. Re-entering the correct password allows the phone to re-authenticate with fresh credentials, often resolving the error immediately.
D
Distractor review
Update the smartphone's firmware.
Firmware updates are not a first-line troubleshooting step for a common authentication issue. They are time-consuming and unlikely to fix a problem that is isolated to a single network and where other devices work.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: 'Forget' the network and reconnect by entering the password again. — When a device sees the SSID but fails authentication despite a correct password, the most common cause is a stale or incorrectly saved credential. The easiest and quickest first step is to 'forget' the network and reconnect from scratch. This clears any corrupted cache or incorrect security settings stored for that network. More drastic steps like resetting network settings or updating firmware should be attempted only if this simple step fails.
What should I do if I get this 220-1101 question wrong?
