Cisco Updated 200-301 Exam Questions and Answers by naia

Cisco DNA Center gathers operational information from network devices through multiple management and telemetry mechanisms, including SNMP, syslog, streaming telemetry, and other device communication methods depending on platform and configuration. It does not require every device to build an IPsec tunnel to exchange normal management data. The answer also is not a separate CU Analyzer tool; the point of DNA Center is centralized assurance, inventory, automation, and analytics. Cisco CCNA 200-301 v1.1 Automation and Programmability expects candidates to understand that controller-based platforms collect data continuously so they can build inventory, report health, detect issues, and drive policy-based changes. Traditional management often depends on manual checks across individual devices. DNA Center centralizes that work and consumes structured operational data from the network. The answer choice that correctly captures that model is A: network devices use services such as SNMP, syslog, and streaming telemetry to send data to the controller.

Use D for this item. HSRP provides first-hop redundancy by giving a group of routers a shared virtual IP address and virtual MAC address. Hosts use the virtual IP as their default gateway; the active router forwards traffic and the standby router takes over if the active fails. In Cisco CCNA 200-301 v1.1, IP Connectivity questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. HSRP is not route load balancing, Layer 2 flooding, or per-packet distribution across routed links. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.

Answer C is the technically correct selection. VLAN hopping is reduced by moving the native VLAN away from VLAN 1 and using an unused VLAN ID for untagged trunk traffic. A double-tagging attack depends on the attacker reaching a trunk that uses the same native VLAN, so making the native VLAN unused removes that easy path. 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. Dynamic ARP Inspection protects ARP, not VLAN tags; ACLs do not stop trunk negotiation; port security alone does not fix native VLAN exposure. 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 C. 802.1X provides identity-based access control at the access layer. A supplicant authenticates through the switch or AP to an authentication server before receiving network access. Cisco CCNA 200-301 v1.1 places this skill in Security Fundamentals, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. DAI, DHCP snooping, and native VLAN changes protect Layer 2 infrastructure but do not authenticate user or device identity in the same way. 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.
