Use A for this item. The global spanning-tree portfast default command makes access ports transition to forwarding immediately when endpoints connect. PortFast is intended for host-facing access ports so DHCP and initial connectivity are not delayed by STP listening and learning behaviour. In Cisco CCNA 200-301 v1.1, Network Access 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. The trunk PortFast command is for special trunk edge cases, and disabling PortFast would not meet the requirement. 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.

R1 uses a network route, not a host route, floating static route, or default route. The destination host is 10.10.13.10/32, but the routing-table entry that matches it is the OSPF-learned network prefix 10.10.13.0/25. That prefix covers host addresses from 10.10.13.1 through 10.10.13.126, so the host address is included. A host route would be a /32 entry specifically for 10.10.13.10. A default route would be 0.0.0.0/0 and would be used only if no more specific route matched. A floating static route is a backup static route with a higher administrative distance; the exhibit shows an OSPF route being selected. Cisco CCNA v1.1 IP Connectivity emphasizes longest-prefix match and route-code interpretation. The router does not care that the destination is a single host; it forwards by the most specific matching route in the table. Here, that route is a network route.

Answer D and E is the technically correct selection. Cisco WLC service-port management supports Telnet and SSH access. The service port is an out-of-band management interface and can be used for direct management connectivity depending on platform configuration. 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. RADIUS and TACACS+ are AAA protocols, and SCP is file transfer, not the pair of management access protocols asked here. 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.

Weighted Random Early Detection is a congestion-avoidance mechanism. It starts dropping selected packets before an output queue becomes completely full, which helps avoid tail drop and TCP global synchronization. WRED can weight the drop behavior by IP precedence or DSCP so lower-priority traffic is more likely to be dropped before higher-priority traffic. That makes options A and D correct. WRED does not guarantee delivery of high-priority packets; it only changes drop probabilities. It also does not perform deep flow identification with high granularity, and it is not a protocol-discovery feature. In QoS design, classification and marking identify traffic, congestion management schedules traffic, and congestion avoidance drops early to prevent queue collapse. CCNA 200-301 v1.1 IP Services includes QoS behavior at a conceptual level, and WRED is best remembered as selective early drop based on traffic marking.
