Full question →mediummultiple choiceObjective-mapped
A user reports that during phone calls on their Android smartphone, the caller's voice sounds very low and muffled through the earpiece speaker. The technician has cleaned the speaker grille with a soft brush and the issue persists. The phone otherwise functions normally with media sounds playing at adequate volume. Which of the following should the technician check 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
Best answer
Check the call volume setting and adjust it during a test call
Call volume is often set independently from media volume. Adjusting it during a call is a quick and logical troubleshooting step to rule out a simple software-level issue.
B
Distractor review
Replace the earpiece speaker module
Replacing the speaker should be done only after confirming that the issue is hardware-related. The speaker works but is muffled; software settings or debris could be the cause. The technician has already cleaned the grille but has not checked software settings.
C
Distractor review
Disable Bluetooth to rule out audio redirection
While Bluetooth could redirect audio to a headset, the symptom of muffled sound from the earpiece suggests the phone's own speaker is still being used. Disabling Bluetooth is a lower priority than checking the call volume.
D
Distractor review
Reset the audio codec settings in developer options
Audio codec settings are typically not user-accessible and are not a common cause of a single speaker sounding muffled. Changing these settings could cause other audio problems and is not the recommended next step.
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: Check the call volume setting and adjust it during a test call — After cleaning the physical speaker grille, the next step is to verify software settings. Call volume is a separate setting from media volume and may be set too low. Checking and adjusting the in-call volume using the volume buttons during a call is a simple and effective troubleshooting step before considering hardware replacement or more complex software issues. Bluetooth settings could redirect audio if a paired device is nearby, but the symptom description (muffled, not absent) is less indicative of Bluetooth redirection than a low volume setting. Audio codec settings are not user-facing and unlikely to cause a muffled sound without other symptoms.
