Cisco 200-301 Online Access

The verified answer is A. The default-router command in a Cisco DHCP pool supplies the default gateway option to DHCP clients. Clients receive that address as the router to use for destinations outside their local subnet. Cisco CCNA 200-301 v1.1 places this skill in IP Services, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. default-gateway is used differently on some switches, ip helper-address relays DHCP, and dns-server supplies name-resolution servers. 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.

This matching item tests the basic roles of common network components. A router forwards packets between IP networks and makes Layer 3 path decisions. A Layer 2 switch forwards Ethernet frames within a VLAN using MAC addresses. A Layer 3 switch can perform switching and inter-VLAN routing in hardware. A firewall controls traffic between security zones and may use stateful inspection, policy, and address translation. A wireless access point bridges wireless clients into the wired network, while a wireless LAN controller centrally manages many lightweight APs. Cisco CCNA v1.1 Network Fundamentals begins with exactly this skill: explain the role and function of routers, switches, APs, controllers, servers, endpoints, and security appliances. The reliable way to solve the drag-and-drop is to identify the forwarding layer and administrative role. MAC-frame movement belongs to Layer 2 switching, subnet-to-subnet forwarding belongs to routing, and centralized WLAN control belongs to the WLC.

The root bridge election is based on the lowest bridge ID. The bridge ID includes priority and MAC address, with priority compared first. If priority values are not provided or are equal, the lowest MAC address becomes the tie-breaker. In the HQ LAN exhibit, Switch 3 has the lowest bridge ID value after the election criteria are applied, so Switch 3 becomes the root bridge. Cisco CCNA 200-301 v1.1 Network Access tests this because STP root placement determines which switch becomes the logical center of the Layer 2 topology. Once the root is selected, all nonroot switches calculate their root ports and designated ports based on path cost and tie-breakers. The physical drawing position of a switch is irrelevant. The root is chosen by numerical bridge ID comparison. The correct answer is C.

In a NAT translation table, the source address seen after inside-to-outside translation is the inside global address. The inside local address is the private address assigned to the internal host. The inside global address is the translated address that represents that internal host to the outside network. In the exhibit-based answer set, 172.23.104.4 is the address used as the translated source, so D is correct. This question is easy to miss if NAT terms are treated as labels instead of traffic direction. For outbound traffic, NAT changes the source from the inside local value to the inside global value. For return traffic, NAT reverses the operation and maps the destination back to the inside local host. Cisco CCNA v1.1 IP Services includes NAT concepts and configuration, so candidates must know inside local, inside global, outside local, and outside global. The tested idea is not merely public versus private; it is which translated field is used as the packet source.
