Cisco Tetration is a Cisco security solution that provides patch management in the cloud. Patch management is the process of identifying, acquiring, installing, and verifying patches for products and systems to correct security and functionality problems in software and firmware1. Cisco Tetration is a cloud-native platform that delivers comprehensive workload protection for multicloud data centers by enabling a zero-trust model using segmentation2. One of the features of Cisco Tetration is software vulnerability detection and patch management, which allows users to identify software vulnerabilities on workloads, prioritize patching based on risk scores, and automate patch deployment using orchestration tools3. Cisco Tetration leverages the National Vulnerability Database (NVD) and Cisco Talos Intelligence Group to provide up-to-date information on software vulnerabilities and their severity levels3. Cisco Tetration also supports patch management for both Windows and Linux operating systems, as well as third-party applications such as Apache, Java, MySQL, and Oracle4. Therefore, the correct answer is D. Cisco Tetration. References: 1: RFC 9232: Network Telemetry Framework - Internet Engineering Task Force 2: Cisco Tetration - Workload Protection - Cisco 3: Cisco Tetration Software Vulnerability Detection and Patch Management - Cisco 4: Cisco Tetration Platform Data Sheet - Cisco
