Cisco Updated 200-301 Exam Questions and Answers by hubert

The correct response is A and B. Static IPv6 host routes use a /128 prefix to identify one exact loopback destination. On the New York router, the Atlanta loopback route points toward Atlanta and the Washington loopback route points toward Washington through the appropriate next-hop addresses. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. Routes using the wrong next hop or serial interface do not precisely satisfy both host reachability requirements. When this appears in a network, the symptom normally confirms the answer: the route installed, the state selected, the packet forwarded, the wireless client behaviour, or the management workflow will follow this rule. That is why this answer is the best fit for the scenario and not just a plausible networking term.

During STP root port selection, a nonroot switch first chooses the port with the lowest root path cost. The root path cost is the cumulative cost from that switch to the root bridge. Only if there is a tie does STP move to tie-breakers such as the lowest upstream bridge ID, lowest upstream port ID, and then lowest local port ID. This order matters because many wrong answers jump directly to bridge ID or port ID. Cisco CCNA 200-301 v1.1 Network Access tests STP because root-port and designated-port decisions determine which links forward and which links block in a Layer 2 topology. The root bridge itself has no root port; every nonroot switch selects one best path toward the root. The first and most important criterion is lowest path cost to the root bridge. That makes option B correct.

The verified answer is B. A port security violation can place a switchport into the err-disabled state. In shutdown violation mode, the switch disables the interface to stop unauthorized MAC address use. Cisco CCNA 200-301 v1.1 places this skill in Network Access, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. Latency, an administratively shut interface, or an unplugged cable do not describe the err-disable trigger in the question. 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.

A floating static route must have a higher administrative distance than the primary route. That is what keeps it out of the routing table while the primary route is valid. If the primary route fails, the routing table process removes the better route and installs the backup static route with the higher AD. Option A states that behavior correctly. If the backup route had a lower administrative distance, it would become preferred immediately and would not act as a backup. Raising the primary route’s distance is not the normal design; the route intended to float is the one configured with the higher distance. The default-information originate command is for advertising a default route into a routing protocol, not for installing a floating static backup. This is core CCNA 200-301 v1.1 IP Connectivity: floating statics provide deterministic fallback when a dynamic route or primary static route disappears.
