Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A user's Android smartphone charges normally when powered off and connected to a wall charger. However, when the phone is powered on and connected to the same charger, the battery percentage decreases over time despite showing the charging icon, eventually causing the phone to shut down. The user has tried multiple charging cables and adapters, performed a factory reset, and the issue persists. 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
The charging port is loose or damaged
A damaged charging port can cause intermittent charging, but the phone charges normally when powered off, indicating the port and cable are functional. The issue is related to power consumption vs. charging rate.
B
Best answer
The battery has reached end-of-life and cannot hold a charge
An aged or defective battery can exhibit increased internal resistance, limiting the charging current it can accept. When the phone is on, the discharge rate exceeds the charge rate, leading to net depletion. This is a classic symptom of a failing battery, especially if the phone is a few years old.
C
Distractor review
The operating system has a bug causing high power drain
A factory reset eliminates software-related issues, including OS bugs. If the problem persisted after a factory reset, it is not a software problem.
D
Distractor review
The mainboard's charging IC is malfunctioning
A faulty charging IC could cause charging problems, but if the phone charges normally when powered off, the IC is likely functional. A defective IC would typically prevent charging or cause no charge indication. The scenario suggests the charging circuitry works, but the battery cannot hold a charge under load.
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 battery has reached end-of-life and cannot hold a charge — The behavior indicates that the device consumes more power while running than the charging circuit can provide. When powered off, minimal power is drawn, so the battery charges normally. When powered on, especially under load, the charge rate may be insufficient, leading to net discharge. This is often due to a faulty battery that cannot accept a charge efficiently, or a degraded battery with high internal resistance. The charging port and cable have been ruled out by testing different accessories. A factory reset eliminates software issues. The mainboard/charging IC is possible but the battery is a more common point of failure and is likely the root cause.
