Full question →hardmultiple choiceObjective-mapped
A security administrator needs to securely erase data from an SSD before repurposing it in another department. The company policy requires that data be completely unrecoverable. Which method should the administrator use?
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
Perform a standard format using Windows File Explorer
A standard format only marks the file system as empty; data remains and can be recovered with forensic tools. It is not secure for SSDs.
B
Distractor review
Run the Diskpart clean command from a command prompt
Diskpart clean removes partition information but does not overwrite data. It is not sufficient for secure erasure.
C
Best answer
Use the ATA Secure Erase command via the drive's firmware or a trusted tool
ATA Secure Erase is specifically designed for SSDs. It triggers the drive's internal mechanism to erase all user data, including cells in spare areas, making recovery infeasible.
D
Distractor review
Degauss the drive with a strong magnetic field
Degaussing can destroy the electronics of an SSD, making it unusable. It is not a recommended method for SSDs and may not completely erase all data due to the way SSDs store information.
Common exam trap
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Technical deep dive
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.

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?
OSPF neighbours must agree on key parameters.
What is the correct answer to this question?
The correct answer is: Use the ATA Secure Erase command via the drive's firmware or a trusted tool — For SSDs, the ATA Secure Erase command is the recommended method because it issues a built-in command to the drive controller to clear all data cells. Degaussing can damage SSDs, and standard formatting or Diskpart clean commands do not guarantee complete data removal due to wear leveling and spare area.
What should I do if I get this 220-1101 question wrong?
