The verified answer is D. service password-encryption encrypts supported plaintext passwords in the running configuration. It provides basic obfuscation for line passwords and other password fields so casual viewers do not see clear text. 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. enable secret protects only the enable secret value, while the other listed commands are not the correct IOS global command. 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 matching is based on identifying the attack layer and then choosing the control that blocks that behavior. Dynamic ARP Inspection validates ARP messages against trusted bindings and is used against ARP spoofing or poisoning, a common man-in-the-middle technique on Layer 2 segments. DHCP snooping builds the trusted binding table and blocks unauthorized DHCP server behavior. Port security limits which MAC addresses can use a switchport, reducing exposure to MAC flooding or unauthorized endpoint attachment. Changing the native VLAN or using proper trunk controls helps mitigate VLAN hopping and double-tagging attacks, because the attacker relies on trunk/native VLAN behavior to cross VLAN boundaries. Cisco CCNA v1.1 Network Access includes switch security features such as DHCP snooping, DAI, and port security. The practical approach is not to memorize coordinates in a drag-and-drop map. Identify the malicious mechanism first, then map it to the feature that checks or constrains that exact mechanism.

In this attack, the attacking computer generates frames with two 802.1Q tags. The first tag matches the native VLAN of the trunk port (VLAN 10 in this case), and the second matches the VLAN of a host it wants to attack (VLAN 20).

The verified answer is C. When identical prefixes are learned from different routing sources, the router compares administrative distance. eBGP has an administrative distance of 20, which is lower than EIGRP internal 90, OSPF 110, and iBGP 200. Cisco CCNA 200-301 v1.1 places this skill in IP Connectivity, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. The router installs the route with the lowest administrative distance unless more specific prefix matching changes the comparison. 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.

Answer B,C is correct: B. R2(config)# interface gi0/0R2(config-if)# ip helper-address 198.51.100.100; C. R1(config)# interface fa0/0R1(config-if)# ip address dhcpR1(config-if)# no shutdown. IP services questions test the exact function of infrastructure services such as addressing, name resolution, time synchronization, logging, monitoring, and secure management. Cisco CCNA 200-301 v1.1 includes this topic under IP Services, so the answer must be validated against normal Cisco device behavior and the operational wording of the scenario. The key is not simply recognizing a familiar acronym; it is identifying what the feature does, where it is configured, and what result it produces. The distractors name valid services, but they provide a different service function from the one required in the prompt. In a real network, selecting the wrong option would either leave the feature nonfunctional, create a forwarding or security gap, or send troubleshooting in the wrong direction. The selected answer is the only one that matches the stated requirement and the way Cisco switching, routing, services, security, wireless, or automation functions are expected to operate. This is why the verified answer remains the best technical choice for the question.
