220-1202 시험 - CompTIA실제시험문제와 답 - 75문항

Question No : 1

Users are reporting that an unsecured network is broadcasting with the same name as the normal wireless network. They are able to access the internet but cannot connect to the file share servers.
Which of the following best describes this issue?

A.Unreachable DNS server
B.Virtual local area network misconfiguration
C.Incorrect IP address
D.Rogue wireless access point

정답:
Explanation:
A rogue access point mimics the legitimate SSID, allowing clients to connect (often with internet access via its own uplink) but isolating them from internal resources like file shares. This behavior matches the symptoms - users join what appears to be the corporate WLAN but can’t reach internal servers.

Question No : 2

After a recent mobile OS upgrade to a smartphone, a user attempts to access their corporate email, but the application does not open. A technician restarts the smartphone, but the issue persists.
Which of the following is the most likely way to resolve the issue?

A.Updating the failed software
B.Registering the smartphone with an MDM solution
C.Installing a third-party client
D.Clearing the cache partition

정답:
Explanation:
After a major OS upgrade, existing applications often require updates to maintain compatibility with new APIs and system libraries. Updating the corporate email app to its latest version ensures it’s built against the updated OS and can launch properly.

Question No : 3

Which of the following methods would make data unrecoverable but allow the drive to be repurposed?

A.Deleting the partitions
B.Implementing EFS
C.Performing a low-level format
D.Degaussing the device

정답:
Explanation:
A low-level format (more accurately, a secure erase that overwrites all sectors with zeroes or random data) effectively wipes all data on the drive, making previous content unrecoverable while leaving the drive’s structure intact for reuse. Unlike degaussing - which destroys the drive’s magnetic media and renders it unusable - overwriting allows the drive to be repurposed safely.

Question No : 4

Which of the following filesystem types does the Linux OS use?

A.exFAT
B.APFS
C.ext4
D.NTFS

정답:
Explanation:
ext4 (Fourth Extended Filesystem) is the default filesystem for most Linux distributions. It offers improved performance, reliability, and support for large volumes and files compared to its predecessors (ext2/ext3).

Question No : 5

An application's performance is degrading over time. The application is slowing, but it never gives an error and does not crash.
Which of the following tools should a technician use to start troubleshooting?

A.Reliability history
B.Computer management
C.Resource monitor
D.Disk

정답:
Explanation:
Resource Monitor provides real-time insights into CPU, memory, disk, and network usage by process. By observing which resources steadily increase or become bottlenecks over time, a technician can pinpoint leaks (e.g., memory), I/O contention, or other performance issues driving the slowdown.

Question No : 6

Technicians are failing to document user contact information, device asset tags, and a clear description of each issue in the ticketing system.
Which of the following should a help desk management team implement for technicians to use on every call?

A.Service-level agreements
B.Call categories
C.Standard operating procedures
D.Knowledge base articles

정답:
Explanation:
Standard operating procedures (SOPs) define consistent, step-by-step guidelines that technicians must follow - such as capturing user contact details, asset tags, and detailed issue descriptions on every ticket. Implementing SOPs ensures thorough and uniform documentation across all calls.

Question No : 7

Which of the following is the quickest way to move from Windows 10 to Windows 11 without losing data?

A.Using gpupdate
B.Image deployment
C.Clean install
D.In-place upgrade

정답:
Explanation:
An in-place upgrade directly installs Windows 11 over the existing Windows 10 installation, preserving user files, applications, and settings. It’s much faster than capturing and redeploying an image, and it avoids the data loss risk of a clean install.

Question No : 8

A technician is deploying mobile devices and needs to prevent access to sensitive data if the devices are lost.
Which of the following is the best way to prevent unauthorized access if the user is unaware that the phone is lost?

A.Encryption
B.Remote wipe
C.Geofencing
D.Facial recognition

정답:
Explanation:
Full-disk (or device) encryption ensures that, even if a lost mobile device is physically accessed by an unauthorized party, its stored data remains inaccessible without the correct decryption credentials. This protection is automatic and continuous, safeguarding data at rest regardless of whether the user realizes the device is missing or not. Remote wipe can remove data if triggered, but it requires the device to be online and the user (or admin) to initiate the wipe―whereas encryption is always in effect.

Question No : 9

An employee is using a photo editing program. Certain features are disabled and require a log-in, which the employee does not have.
Which of the following is a way to resolve this issue?

A.License assignment
B.VPN connection
C.Application repair
D.Program reinstallation

정답:
Explanation:
When features in an application are disabled pending a login, it typically indicates those capabilities are controlled by the software’s licensing system. Assigning (or activating) the proper license entitles the user to those premium features, restoring full functionality without unnecessary repair or reinstall steps.

Question No : 10

A user receives a new personal computer but is unable to run an application. An error displays saying that .NET Framework 3.5 is required and not found.
Which of the following actions is the best way to resolve this issue?

A.Resolve the dependency through the 'Turn Windows features on or off' menu.
B.Download the dependency via a third-party repository.
C.Ignore the dependency and install the latest version 4 instead.
D.Forward the trouble ticket to the SOC team because the issue poses a great security risk.

정답:
Explanation:
Windows includes .NET Framework 3.5 as an optional feature. Enabling it via Control Panel → Programs and Features → Turn Windows features on or off ensures the OS installs the correct version directly from Microsoft without relying on untrusted sources or skipping needed dependencies.

Question No : 11

A help desk technician is setting up speech recognition on a Windows system.
Which of the following settings should the technician use?

A.Time and Language
B.Personalization
C.System
D.Ease of Access

정답:
Explanation:
Windows places speech recognition and other accessibility features under the Ease of Access settings. From there, you can configure Speech options - including enabling Windows Speech Recognition and adjusting its settings - so that users relying on voice input can operate the system effectively.

Question No : 13

Which of the following describes a vulnerability that has been exploited before a patch or remediation is available?

A.Spoofing
B.Brute-force
C.DoS
D.zero-day

정답:
Explanation:
A zero-day vulnerability refers to a security flaw that is actively exploited by attackers before the software vendor has released a patch or remediation - meaning defenders have “zero days” to prepare once the exploit becomes known.

A small office reported a phishing attack that resulted in a malware infection.
A technician is investigating the incident and has verified the following:
● All endpoints are updated and have the newest EDR signatures.
● Logs confirm that the malware was quarantined by EDR on one system.
● The potentially infected machine was reimaged.
Which of the following actions should the technician take next?

A.Install network security tools to prevent downloading infected files from the internet.
B.Discuss the cause of the issue and educate the end user about security hygiene.
C.Flash the firmware of the router to ensure the integrity of network traffic.
D.Suggest alternate preventative controls that would include more advanced security software.

정답:
Explanation:
With technical controls updated, EDR signatures current, and the infected system reimaged, the next step is to address the human factor. Educating the user on how to recognize phishing attempts and follow safe practices helps prevent recurrence and strengthens the organization’s overall security posture.

Question No : 15

A user recently installed an application that accesses a database from a local server. When launching the application, it does not populate any information.
Which of the following command-line tools is the best to troubleshoot the issue?

A.ipconfig
B.nslookup
C.netstat
D.curl

정답:
Explanation:
netstat reveals active network connections and listening ports on the local machine. By using it, you can confirm that the application has successfully opened (or attempted) a connection to the database server’s port, verify the remote server’s address and port, and detect any failed or hanging TCP sessions that would prevent data retrieval.
