Answer C,D is correct: C. no service password-encryption; D. no ip name-server 198.51.100.210. IP services questions are about the supporting protocols that make a network manageable and usable: DHCP supplies addressing information, DNS resolves names, NAT translates address spaces, NTP synchronizes time, syslog records events, SNMP monitors devices, and QoS classifies or prioritizes traffic. Cisco IOS commands are precise; a similar-looking command can configure a client, a relay, a pool, or a server role depending on context. The incorrect options typically name real services but solve a different operational problem. Cisco CCNA 200-301 v1.1 includes these topics because production networks fail just as often from broken services as from broken routing. The chosen answer is the one that performs the exact function in the scenario, whether that is file transfer, address assignment, logging level selection, monitoring security, or traffic treatment.

Administrative distance is the feature that routers use to select the best path when there are two or more different routes to the same destination from two different routing protocols. A lower numerical value is preferred.
Note on EIGRP: While the letter "R" typically stands for RIP (AD 120), in this specific Cisco output, the brackets show [90/1]. Since the AD is 90, this indicates EIGRP (internal). If it were RIP, the first number in the brackets would be 120.
Note on "Connected": While "Connected" (AD 0) is technically the "best" or most trusted, it is generally categorized as a route type rather than a dynamic routing protocol. In the context of
"Which routing protocol," we look at EIGRP, OSPF, and RIP.

A cloud-based architecture enables centralized management of APs across multiple branch locations. This approach allows administrators to push firmware updates, configuration changes, and security policies from a cloud-based dashboard to all connected APs, ensuring consistency and reducing manual effort. Unlike autonomous APs, which require individual configuration, cloud-based solutions streamline network management, making them ideal for enterprises with distributed sites.
