220-1202 Practice Test 41 — 15 Questions

Question 1

A help desk technician receives a complaint that a shared file in /opt/app/data cannot be read by any user except root. The file permissions are -rw-------, and the file's group is already set to developers. Which command will allow the group 'developers' to read the file?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

chmod g+r /opt/app/data. The file currently has permissions `-rw-------`, meaning only the owner (root) has read and write access. To allow the group 'developers' to read the file, you need to add read permission for the group. The command `chmod g+r /opt/app/data` adds read permission for the group, which is the correct approach. This directly addresses the requirement without altering other permissions unnecessarily.

Answer

chmod o+r /opt/app/data

Answer

chmod 644 /opt/app/data

Answer

chown :developers /opt/app/data

Question 2

After deploying a new Windows 11 workstation, a user complains that their screens turn off after 3 minutes of inactivity, even though they are reading documents. They want the display to stay on for at least 15 minutes. Which Settings page should you navigate to in order to change this power setting?

Accepted Answer

Settings > System > Power & battery > Screen and sleep. The modern Windows 11 Settings app consolidates power management under System > Power & battery, where the 'Screen and sleep' section allows you to adjust the 'On battery power, turn off my screen after' and 'When plugged in, turn off my screen after' drop-downs. This directly addresses the user's complaint about the display turning off after 3 minutes of inactivity, enabling a change to 15 minutes.

Answer

Settings > Personalization > Lock screen

Answer

Control Panel > Power Options > Edit Plan Settings

Answer

Settings > Accessibility > Display

Question 3

During a routine security audit, a technician finds that a user's computer has an unknown program running that is sending keystrokes and screenshots to a remote server. The user did not install this program. Which type of malware is this?

Accepted Answer

Keylogger. The described behavior—capturing keystrokes and screenshots and sending them to a remote server—is the defining characteristic of a keylogger. This type of malware specifically records user input and screen activity to steal sensitive data like passwords and personal information, and it often runs without the user's knowledge or consent.

Answer

Rootkit

Answer

Worm

Answer

Ransomware

Question 4

A user reports that they cannot execute a shell script they wrote in their home directory. The script has permissions -rw-r--r--. Which command should be used to allow the owner to execute the script?

Accepted Answer

chmod u+x script.sh. The script currently has permissions -rw-r--r--, meaning the owner has read and write but not execute. The command chmod u+x adds execute permission for the owner (u) without affecting other permissions. This directly addresses the user's inability to execute the script by granting the missing execute bit to the owner.

Answer

chmod 755 script.sh

Answer

chmod +r script.sh

Answer

chmod 644 script.sh

Question 5

A junior admin needs to list all files in /var/log that were modified in the last 24 hours. Which command accomplishes this?

Accepted Answer

find /var/log -mtime 0. The `find` command with `-mtime 0` searches for files whose modification time is within the last 24 hours. The `-mtime` argument uses a 24-hour period, where `0` means modified less than 24 hours ago, making it the precise tool for this task.

Answer

ls -la /var/log | grep '24 hours'

Answer

find /var/log -atime 0

Answer

locate /var/log | sort -m

Question 6

A user reports that a script they run daily now fails with 'Text file busy' error. The script is located on an NFS mount. Which command will show if the script is currently being used by another process?

Accepted Answer

lsof /path/to/script. `lsof /path/to/script` lists all processes that have the file open, including those holding it for execution. The 'Text file busy' error occurs when a process is executing the script (the text segment is mapped), and `lsof` can detect this by showing the file descriptor or memory mapping for the running process.

Answer

fuser /path/to/script

Answer

ps aux | grep script

Answer

strace -p $(pgrep script)

Question 7

A company's security policy mandates that all wireless traffic must be encrypted using a protocol that is resistant to KRACK attacks. The current network uses WPA2-PSK with AES. Which of the following upgrades should be implemented to meet this requirement?

Accepted Answer

Upgrade to WPA3-Personal.. WPA3-Personal replaces the Pre-Shared Key (PSK) handshake with Simultaneous Authentication of Equals (SAE), which is resistant to offline dictionary attacks and the KRACK vulnerability that exploits the 4-way handshake in WPA2. Since the policy requires encryption resistant to KRACK attacks, upgrading to WPA3-Personal directly addresses this requirement.

Answer

Change the encryption from AES to TKIP.

Answer

Enable WPA2-Enterprise with 802.1X.

Answer

Implement MAC address filtering.

Question 8

During a software deployment, you need to configure a Windows 10 workstation to automatically start a legacy application every time a specific user logs on. Which tool should you use to add this startup entry for that user only?

Accepted Answer

Computer Management. Computer Management (compmgmt.msc) contains Local Users and Groups, where you can open the target user's properties and set a logon script on the Profile tab. That script runs only for that user at logon, satisfying the requirement. Services.msc manages system services and is not user-specific. Task Manager's Startup tab only enables or disables existing startup entries; it cannot add new ones. Local Group Policy Editor applies User Configuration policies, including logon scripts, to all users of the computer, so it is not the primary tool for a single specified user.

Answer

Services.msc

Answer

Task Manager

Answer

Local Group Policy Editor

Question 9

A user's Android phone is running extremely slowly after installing a new launcher app. They want to revert to the default launcher without losing data. What is the correct procedure?

Accepted Answer

Go to Settings > Apps > Default apps > Home app and select the default launcher.. Android allows users to change the default home app via Settings > Apps > Default apps > Home app without uninstalling the new launcher or losing any data. This procedure simply reassigns the default launcher to the system's built-in launcher, preserving all installed apps, settings, and user data.

Answer

Uninstall the new launcher app via the Play Store.

Answer

Perform a factory reset from Recovery Mode.

Answer

Clear the cache partition from Recovery Mode.

Question 10

A technician needs to copy a directory tree from /home/user/docs to a backup location /backup/docs, preserving all permissions, ownership, and timestamps. Which command should they use?

Accepted Answer

cp -a /home/user/docs /backup/docs. The `cp -a` (archive) command preserves all file attributes, including permissions, ownership, and timestamps, while recursively copying the entire directory tree. This is the most comprehensive single command for duplicating a directory with full metadata integrity.

Answer

cp -r /home/user/docs /backup/docs

Answer

cp -p /home/user/docs /backup/docs

Answer

rsync -r /home/user/docs /backup/docs

Question 11

A user on iOS 17 complains that their iPhone's battery drains quickly and the phone gets warm during normal use. They have not installed any new apps recently. Which built-in tool should you use first to identify the cause?

Accepted Answer

Settings > Battery. The user reports rapid battery drain and heat during normal use, which usually indicates an app or process consuming excessive power. The first built-in diagnostic step is Settings > Battery, which shows battery usage by app and activity over the last 24 hours or 10 days, allowing you to identify the specific cause. Battery Health only reports maximum capacity and peak performance capability; it can reveal degradation but does not identify which app or process is causing the drain.

Answer

Settings > General > iPhone Storage

Answer

Settings > Privacy > Analytics & Improvements

Answer

Settings > Display & Brightness

Question 12

A technician is tasked with disposing of a failed SSD that contains encrypted financial records. The SSD is non-functional and cannot be powered on. Which method should the technician use to ensure data is destroyed?

Accepted Answer

Physically shred the SSD using an industrial shredder.. The SSD is non-functional and cannot be powered on, so any software-based method (secure erase, overwriting) is impossible. Physical destruction via an industrial shredder is the only reliable way to ensure the encrypted financial records are unrecoverable from a dead SSD, as it physically breaks the NAND chips beyond repair.

Answer

Use a degausser on the SSD.

Answer

Perform a secure erase command via SATA interface.

Answer

Overwrite the SSD with a data wiping tool on another computer.

Question 13

A user reports that their laptop frequently disconnects from the office Wi-Fi and reconnects after a few seconds. The network uses WPA2-Enterprise with PEAP-MSCHAPv2. Other users do not experience this issue. What is the most likely cause?

Accepted Answer

The laptop's wireless driver is outdated.. The most likely cause is an outdated or incompatible wireless driver. This can cause intermittent connectivity issues on a single device. Other users are unaffected, and since the network uses WPA2-Enterprise with PEAP-MSCHAPv2, which relies on username/password authentication, the RADIUS server does not reject client certificates. Channel congestion would affect multiple users, and power saving mode typically turns off the adapter after inactivity, not causing frequent reconnects.

Answer

The RADIUS server is rejecting the laptop's certificate intermittently.

Answer

The office Wi-Fi channel is congested.

Answer

The laptop's power saving mode is turning off the Wi-Fi adapter.

Question 14

A user reports that their iPhone 13 is not receiving text messages from Android users, but iMessage conversations with other iPhone users work fine. After checking that the user is not blocked, which step should you take to resolve this issue?

Accepted Answer

Sign out of iCloud and sign back in.. When an iPhone user cannot receive SMS/MMS from Android users but iMessage works with other iPhones, the issue is typically an iMessage registration conflict. The standard fix is to sign out of iCloud (or Apple ID) and sign back in, which re-registers the phone number with Apple's iMessage servers. Disabling iMessage would stop iMessage functionality entirely and is not the recommended resolution for this specific symptom.

Answer

Disable iMessage in Settings > Messages.

Answer

Reset Network Settings from General > Reset.

Answer

Toggle Airplane Mode on and off.

Question 15

A technician is configuring a shared Android tablet for a retail kiosk. The tablet should only run a single point-of-sale app and prevent users from accessing settings or other apps. Which Android feature should be used?

Accepted Answer

Use Screen Pinning from the Overview (Recent Apps) menu. Screen Pinning is the correct Android feature for kiosk mode because it locks the device to a single app, preventing users from navigating away to settings or other apps. When enabled from the Overview (Recent Apps) menu, it requires a PIN or password to unpin, ensuring the point-of-sale app remains the only accessible interface. This directly meets the requirement of a dedicated retail kiosk without needing third-party software or complex configurations.

Answer

Enable Guest Mode

Answer

Boot the device into Safe Mode

Answer

Install a launcher replacement app
