172.28.0.0/16 is the only private IPv4 network in the list. RFC 1918 reserves three private address blocks for internal use: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The 172.16.0.0/12 block covers 172.16.0.0 through 172.31.255.255, so 172.28.0.0/16 falls cleanly inside the private range. Private addresses are not globally routed on the public Internet and are commonly used for internal LANs, labs, branch networks, and enterprise addressing plans. The other listed choices are either invalidly written or outside the RFC 1918 private ranges. In real networks, private addressing is normally paired with NAT or routed only inside the organization. CCNA 200-301 v1.1 Network Fundamentals requires candidates to identify private IPv4 ranges and understand why they allow internal communication without Internet-routable addressing. Reference: Cisco CCNA IPv4 addressing fundamentals and RFC 1918 private address allocation.

The root bridge is the switch with the lowest bridge ID in the spanning-tree instance. The bridge ID comparison starts with priority. If priorities tie, the lower MAC address wins. In many exam exhibits, the correct root is not the switch drawn at the top or center of the topology; it is the switch with the numerically lowest STP identifier. For this exhibit, S2 has the lowest resulting bridge ID, so it becomes the root bridge. Cisco CCNA 200-301 v1.1 Network Access expects engineers to calculate this cleanly because root selection determines which links forward and which links block. Once S2 is elected, all other switches calculate their lowest-cost path back to S2 and choose root ports accordingly. Design practice is to place the root bridge deliberately, normally near the distribution layer, rather than leaving the outcome to MAC address tie-breakers. In this question, the election result is S2, which maps to answer B.

When Link Aggregation is enabled on a Cisco Wireless LAN Controller, the controller ' s distribution ports operate as a single logical bundle toward the switch. A key operational point is that client traffic can pass as long as at least one physical member link in the bundle is functional. The design improves redundancy and aggregate capacity without requiring each WLAN or AP manager function to be tied to a separate physical port. The switch side must be configured consistently for the supported aggregation mode, but the exam statement being tested here is the resiliency behavior: one working physical port can keep traffic moving. The incorrect choices either imply that two or more active ports are mandatory just to pass client traffic, or describe bandwidth loss in a way that is not the defining LAG behavior. Cisco CCNA 200-301 v1.1 Network Access includes WLC connectivity concepts because AP and client traffic depend on controller uplink design. The correct statement is that one functional physical port is enough to pass client traffic.

By default, EIGRP calculates its composite metric using bandwidth and delay. The classic Cisco explanation is that the default K values make bandwidth and delay active, while reliability, load, and MTU are not used in the default metric calculation. Bandwidth is based on the slowest link along the path, and delay is cumulative across the path. Cisco CCNA 200-301 v1.1 includes EIGRP route-selection fundamentals even though advanced EIGRP tuning is beyond the basic exam depth. The wrong answers describe other protocols or incorrect defaults. OSPF uses cost, often derived from reference bandwidth divided by interface bandwidth. RIP uses hop count. EIGRP does not assign a universal default metric of 10 to learned routes. In practical troubleshooting, engineers compare feasible distance and successor routes, but the metric itself still comes from bandwidth and delay unless the K values are changed. For this question, the direct and tested answer is A.
