Which of the following should a network engineer check to verify that updates are still being released for a device? The correct answer is B. EOL documentation. If a network engineer wants to confirm whether a device is still receiving updates, patches, or vendor support, the first thing to review is the vendor's End-of-Life (EOL) and often related End-of-Support (EOS) documentation. These documents show whether the device is still actively supported, whether firmware and security updates are still being issued, and when that support is scheduled to stop. This is important in network operations because devices that are no longer supported can become security risks and operational liabilities. Once a vendor declares a product end-of-life or end-of-support, future bug fixes, feature releases, and security updates may no longer be available. That directly affects patch management, lifecycle planning, and risk assessment. The other choices do not answer the question as directly. A baseline configuration shows the intended device settings, not the support status. Asset inventory licensing helps track ownership, software entitlements, or subscriptions, but it does not prove that updates are still being released. Software development life cycle refers to the process of building software, not the support state of a deployed network device. For Network+ exam purposes, when the question asks whether updates are still being released, the best source is the vendor's EOL documentation.
