TheDo Not Disturbsetting in Windows Notification settings allows users to suppress all notification banners and sounds during presentations or video calls.

FromTravis Everett – All-in-One Exam Guide:

“Use Windows ‘Do Not Disturb’ to prevent notifications from interrupting full-screen apps like video conferencing.”

When a technician exhausts all troubleshooting steps within their knowledge and the issue remains unresolved, the best practice is to escalate the issue to a higher-level technician or team. Additionally, the technician should clearly communicate the next steps to the customer to maintain transparency and reduce frustration. This ensures continuity of support and upholds customer satisfaction.

B. Dismissing the customer is unprofessional and violates proper customer service protocols.

C. Interrupting the customer and providing excuses escalates the tension and is inappropriate.

D. Continuing to ask questions without new troubleshooting steps wastes time and increases frustration.

The correct answer is B. The SATA HDD power cable is disconnected, because RAM upgrades require opening the case, which can easily result in accidentally loosening or disconnecting internal cables. If the system cannot detect the boot drive, it will display a “No boot device found” error.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, one of the first troubleshooting steps after hardware changes is to verify that all internal cables—especially SATA data and power cables—are securely connected. A disconnected drive will not be detected by the BIOS or UEFI firmware.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that boot order changes are less likely unless the technician explicitly modified BIOS settings. Similarly, reformatting a drive would not occur during a RAM upgrade.

The Mike Meyers / Mark Soper Lab Manual reinforces that physical connection issues are among the most common causes of boot failures following hardware maintenance. A disconnected power cable prevents the hard drive from spinning up, making it invisible to the system.

Because the issue appeared immediately after opening the case for a RAM upgrade, the most likely cause is a disconnected SATA power cable, making B the correct answer.

The correct answer is C. SAML. Security Assertion Markup Language is commonly used for single sign-on between an identity provider and a service provider, especially when an organization wants a third-party application to trust its existing identity service. The CompTIA A+ objectives include SSO, meaning single sign-on, and the objectives’ acronym list identifies SSO as a relevant exam term. In this scenario, the organization wants users to authenticate through its existing identity system rather than maintaining separate credentials for the third-party application. SAML is the best match because it passes authentication assertions between trusted parties. OTP means one-time password and is an authentication factor, not an SSO federation standard. ACL means access control list and controls permissions to resources. UAC is Windows User Account Control, which prompts for administrative approval on a local system. Therefore, SAML is the correct technology for third-party SSO integration.
