Question #1
An employee has repeatedly contacted a technician about malware infecting a work computer. The technician has removed the malware several times, but the user's PC keeps getting infected. Which of the following should the technician do to reduce the risk of future infections?
Correct answer: C
Explanation
Malware is software that infects computer systems to damage, disable or exploit the computer or network for various malicious purposes5. Malware is typically distributed via email attachments, fake internet ads, infected applications or websites, and often relies on user interaction to execute6. Therefore, one of the most effective ways to prevent malware infections is to educate the end user about the common signs and sources of malware, and how to avoid them7. Configuring the firewall, restoring the system from backups, and updating the antivirus program are also important security measures, but they do not address the root cause of the user’s repeated infections, which is likely due to a lack of awareness or caution.

Question #2
A user is no longer able to start the OS on a computer and receives an error message indicating there is no OS found. A technician reviews the audit logs and notes that the user's system posted a S.M.A.R.T. error just days before this issue. Which of the following is the MOST likely cause of this issue?
Correct answer: C
Explanation
A S.M.A.R.T. error is a warning that a hard drive is about to fail or has failed. This means that the OS cannot be loaded from the drive and the user will see an error message indicating there is no OS found. The most likely cause of this issue is drive failure.
Question #6
A user reports that the pages flash on the screen two or three times before finally staying open when attempting to access banking web pages. Which of the following troubleshooting steps should the technician perform NEXT to resolve the issue?
Correct answer: B
Explanation
The next troubleshooting step that the technician should perform to resolve the issue of pages flashing on the screen before staying open when accessing banking web pages is to verify the address bar URL. The address bar URL is the web address that appears in the browser’s address bar and indicates the location of the web page being accessed. Verifying the address bar URL can help determine if the user is accessing a legitimate or malicious website, as some phishing websites may try to impersonate banking websites by using similar-looking URLs or domains.
Question #8
A hotel's Wi-Fi was used to steal information on a corporate laptop. A technician notes the following security log: SRC: 192.168.1.1/secrets.zip Protocol SMB >> DST: 192.168.1.50/capture The technician analyses the following Windows firewall information: Which of the following protocols most likely allowed the data theft to occur?
Correct answer: D
Explanation
The protocol that most likely allowed the data theft to occur is SMB over TCP port 445. SMB is a network file sharing protocol that enables access to files, printers, and other resources on a network. Port 445 is used by SMB to communicate directly over TCP without the need for NetBIOS, which is an older and less secure protocol. The security log shows that the source IP address 192.168.1.1 sent a file named secrets.zip using SMB protocol to the destination IP address 192.168.1.50, which captured the file. The Windows firewall information shows that port 445 is enabled for inbound and outbound traffic, which means that it is not blocked by the firewall. Therefore, port 445 is the most likely port that was exploited by the attacker to steal the data from the corporate laptop.

By adding the update site to the exceptions list, the client will be able to access the site and download the software update.
