The correct answer is EOL discontinues the product but may offer support. According to CompTIA Network+ (N10-009) objectives related to lifecycle management and vendor support policies, End of Life (EOL) indicates that a product is no longer being manufactured or sold by the vendor. However, after EOL is declared, the vendor may continue to provide limited support, updates, or warranty services for a defined period.

In contrast, End of Support (EOS) means the vendor has stopped providing technical assistance, patches, firmware updates, and security fixes for the product. Once a product reaches EOS, organizations are responsible for maintaining it without vendor assistance, which can introduce operational and security risks.

Option B is incorrect because EOS does not typically convert support into a subscription model—it signifies the termination of support. Option C is incorrect because EOS applies to both hardware and software products. Option D is incorrect because warranty terms depend on vendor policy and are not guaranteed after EOL status.

Therefore, the key distinction is that EOL ends product sales, while EOS ends vendor support.
