Answer the displayed drag-and-drop mapping is the technically correct selection. DHCP snooping builds a trusted binding table from legitimate DHCP exchanges. Trusted ports face valid DHCP servers, untrusted ports face clients, and the binding database becomes the source of truth for features such as Dynamic ARP Inspection and IP Source Guard. This aligns with Cisco CCNA 200-301 v1.1 because the exam blueprint requires engineers to recognize operational behaviour from configuration symptoms and topology requirements. Ordinary MAC learning does not validate DHCP messages, and trunking or STP alone cannot prevent a rogue DHCP server from handing out false gateways. Treat the distractors carefully: most are real Cisco terms, but they solve a different problem or operate at a different layer. The selected answer is the one that would be used by an engineer on the device or in the design to produce the outcome stated in the question.

The verified answer is D. Server virtualization allows multiple operating systems to run independently on one physical host. A hypervisor abstracts CPU, memory, storage, and network resources so each VM behaves like a separate machine. Cisco CCNA 200-301 v1.1 places this skill in Network Fundamentals, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. VRF and virtual device contexts virtualize network functions, not general-purpose operating systems on a host computer. In production, this distinction matters because a misapplied command or design choice usually creates an outage, a security gap, or unnecessary troubleshooting noise. The correct choice matches the control-plane, data-plane, wireless, security, or services behaviour described in the scenario and should be preferred over options that merely sound related.

The drag-and-drop mapping is based on each tool’s normal configuration-management model. Ansible is agentless, built around playbooks, and commonly uses SSH over TCP port 22 to communicate with managed nodes. Puppet uses a declarative model and stores configuration logic in manifests, typically written with Puppet’s Ruby-influenced language and saved as .pp files. Chef uses recipes and cookbooks and is associated with a client/server automation model; Chef Push Jobs also uses a command channel for remote execution. The important CCNA 200-301 v1.1 Automation and Programmability lesson is not to memorize marketing language but to separate the operating models: Ansible focuses on simple agentless execution, Puppet emphasizes declarative manifests, and Chef organizes configuration into recipes and cookbooks. The existing mapping follows those technology roles. Reference: Cisco CCNA automation objectives covering configuration management tools and common network automation characteristics.

This drag-and-drop item maps common Layer 2 and access-layer threats to their mitigation controls. Dynamic ARP Inspection protects against ARP spoofing or poisoning by validating ARP packets against trusted binding information. DHCP snooping blocks rogue DHCP behavior and builds the binding table used by other protections. BPDU Guard protects PortFast edge ports by err-disabling a port that receives an unexpected spanning-tree BPDU, which helps prevent rogue switch insertion. A nondefault or unused native VLAN, combined with disabling DTP and manually configuring trunks, reduces VLAN hopping exposure. Cisco CCNA 200-301 v1.1 Security Fundamentals and Network Access both touch these controls because many campus attacks happen before traffic ever reaches a firewall. The dependable way to solve the matching is to identify the abused protocol: ARP attacks map to DAI, DHCP attacks map to DHCP snooping, unexpected switch/STP participation maps to BPDU Guard, and trunk/native-VLAN abuse maps to VLAN-hopping mitigation.
