WITH VERIFIED ANSWERS 2026 EDITION.
Where would you look for the option to view and configure wireless adapter status in macOS?
n the Status menu on the Menu bar, in the top-right of the screen, or in the Network prefpane.
A DHCP server has been reconfigured to use a new network address scheme following a network
problem. What command would you use to refresh the IP configuration on Windows client
workstations?
ipconfig /renew
Early in the day, a user called the help desk saying that his computer is running slowly and freezing up.
Shortly after this user called, other help desk technicians who overheard your call also received calls
from users who report similar symptoms. Is this likely to be a malware infection?
It is certainly possible. Software updates are often applied when a computer is started in the morning,
so that is another potential cause, but you should investigate and log a warning so that all support staff
are alerted. It is very difficult to categorize malware when the only symptom is performance issues.
However, performance issues could be a result of a badly written Trojan, or a Trojan/backdoor
application might be using resources maliciously (for DDoS, Bitcoin mining, spam, and so on).
You are documenting workstation backup and recovery methods and want to include the 3-2-1
backup rule. What is this rule?
It states that you should have three copies of your data across two media types, with one copy held
offline and offsite. The production data counts as one copy.
Another user calls to say he is trying to sign-on to his online banking service, but the browser reports
that the certificate is invalid. Should the bank update its certificate, or do you suspect another cause?
It would be highly unlikely for a commercial bank to allow its website certificates to run out of date or
otherwise be misconfigured. You should strongly suspect redirection by malware or a
phishing/pharming scam.
What feature of modern file systems assists recovery after power outages or OS crash events?
Journaling means that the file system keeps a log of updates that it can use to recover damaged data.
The OS might also make use of snapshot capability to maintain a file-version history or perform
continuous backups.
Advanced malware can operate covertly with no easily detectable symptoms that can be obtained by
scanning the device itself. What other type of symptom could provide evidence of compromise in this
scenario?
Leaked data files or personal information such as passwords.
Which Linux command will display detailed information about all files and directories in the current
directory, including system files?
, ls -la
Angel brought in the new tablet he just purchased and tried to connect to the corporate network. He
knows the SSID of the wireless network and the password used to access the wireless network. He
was denied access, and a warning message was displayed that he must contact the IT Department
immediately. What happened, and why did he receive the message?
Mobile device management (MDM) is being used to mediate network access. The device must be
enrolled with the MDM software before it can join the network.
What command could you use to move a file names.doc from your current directory to the USB stick
linked to folder /mnt/usb?
mv names.doc /mnt/usb
A security consultant has recommended blocking end-user access to the chrome://flags browser page.
Does this prevent a user from changing any browser settings?
No. The chrome://flags page is for advanced configuration settings. General user, security, and privacy
settings are configured via chrome://settings.
You are pinging a host at 192.168.0.99 from a host at 192.168.0.200. The response is "Reply from
192.168.0.200: Destination host unreachable." The hosts use the subnet mask 255.255.255.0. Does
the ping output indicate a problem with the default gateway?
No. The hosts are on the same IP network (192.168.0.0/24). This means that 192.168.0.200 does not try
to use a router (the gateway) to send the probes. 192.168.0.200 uses address resolution protocol (ARP)
to find the host with the IP 192.168.0.99. The host unreachable message indicates that there was no
response, but the problem will be an issue such as the host being disconnected from the network or
configured to block discovery rather than a gateway issue.
An employee has a private license for a graphics editing application that was bundled with the
purchase of a digital camera. The employee needs to use this temporarily for a project and installs it
on her computer at work. Is this a valid use of the license?
No. The license is likely to permit installation to only one computer at a time. It might or might not
prohibit commercial use, but regardless of the license terms, any installation of software must be
managed by the IT department.
You are supporting a home user with upgrading a computer from Windows 10 to Windows 11. You
have run Microsoft's PC Health Check tool, and it verifies that the computer meets the hardware
requirements. Should you now proceed with the in-place upgrade?
No. You must backup user data and settings first. A backup is essential as a security precaution.
You are monitoring system performance and notice that a substantial number of page faults are
occurring. Does this indicate that a memory module is faulty?
No—it shows the system is using the pagefile intensively and could benefit from more system RAM
being installed.
