A certificate is a digital document that verifies the identity and authenticity of a website. A certificate is issued by a trusted authority called a certificate authority (CA). A certificate contains information such as the website's domain name, the CA's name, the expiration date, and a digital signature. If a website's certificate is expired, invalid, or untrusted, the browser will warn the user that the site may not be secure and prompt them to click a link to continue. The user can check the certificate validity by clicking on the padlock icon next to the address bar and viewing the certificate details.Reference: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 6, Section 6.2, Page 260.

A UPS (uninterruptible power supply) provides protection against power outages by providing backup power to connected devices in case of a power failure. A UPS typically consists of a battery, an inverter, and a surge protector. A UPS can prevent data loss, hardware damage, or downtime caused by sudden loss of electricity. A UPS can also protect against power surges, spikes, or fluctuations that can harm electronic devices.

A denial of service (DoS) is a cyberattack that attempts to disrupt the normal functioning of a network or system by overwhelming it with traffic or requests. A UPS does not provide protection against DoS attacks, as they target the network layer, not the physical layer. A replay attack is a cyberattack that involves intercepting and retransmitting data to impersonate or deceive another party. A UPS does not provide protection against replay attacks, as they target the application layer, not the physical layer. Wiretapping is the act of secretly monitoring or recording the communication or data transmission of another party. A UPS does not provide protection against wiretapping, as it does not encrypt or secure the data.
