Which of the following is the best way to distribute custom images to 800 devices that include four device vendor classes with two types of user groups?
Answer(s): D
A network-based remote installation tool (such as Windows Deployment Services, MDT, or a similar solution) scales efficiently across hundreds of devices with varying hardware and user configurations. It allows you to segment deployments by vendor classes and user groups, automate imaging processes, and manage version control centrally - far more effectively than one-to-one cloning or file-copy methods.
Which of the following types of social engineering attacks sends an unsolicited text message to a user's mobile device?

A user reports some single sign-on errors to a help desk technician. Currently, the user is able to sign in to the company's application portal but cannot access a specific SaaS-based tool. Which of the following would the technician most likely suggest as a next step?
Answer(s): B
Single sign-on issues that affect only a specific application often stem from stale or conflicting session data in the user’s browser. Launching a private (incognito) window ensures a fresh session without cached cookies or tokens, which can resolve access to the SaaS tool without affecting other configurations.
