Answer B is the technically correct selection. NETCONF filtering is done by creating an XML filter and passing it to the get_config operation. NETCONF uses XML-encoded RPC messages, so an XML subtree or XPath-style filter reduces the returned configuration to the requested interface section. 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. Parsing with JSON or sending a JSON filter does not match NETCONF data encoding; parsing after retrieval does not reduce server response size. 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.

Cisco DNA Center gathers operational information from network devices through multiple management and telemetry mechanisms, including SNMP, syslog, streaming telemetry, and other device communication methods depending on platform and configuration. It does not require every device to build an IPsec tunnel to exchange normal management data. The answer also is not a separate CU Analyzer tool; the point of DNA Center is centralized assurance, inventory, automation, and analytics. Cisco CCNA 200-301 v1.1 Automation and Programmability expects candidates to understand that controller-based platforms collect data continuously so they can build inventory, report health, detect issues, and drive policy-based changes. Traditional management often depends on manual checks across individual devices. DNA Center centralizes that work and consumes structured operational data from the network. The answer choice that correctly captures that model is A: network devices use services such as SNMP, syslog, and streaming telemetry to send data to the controller.

A DHCP server maintains address pools and leases IP configuration to clients. The most basic information it holds is the list or range of available IP addresses that can be assigned from a pool, along with related options such as default gateway, DNS servers, domain name, and lease duration. It does not store public DNS name mappings; that is a DNS function. It does not normally store domain usernames and passwords; that belongs to directory or AAA systems. Static MAC-to-IP reservations can exist in DHCP, but the broad answer being tested is the available address pool. Cisco CCNA 200-301 v1.1 IP Services requires candidates to understand DHCP server, client, relay, pool, lease, exclusion, and default-router behavior. When a client sends DHCPDISCOVER, the server selects an address from the configured pool and offers it with network parameters. Therefore, the correct answer is A.

PortFast is the spanning-tree enhancement that allows an edge port to transition directly to forwarding instead of waiting through the traditional listening and learning delays. It is intended for ports connected to end hosts, not for switch-to-switch links. If a switch is connected to a PortFast port by mistake, a loop can form unless protections such as BPDU Guard are used. BPDU Guard and BPDU Filter affect BPDU handling; they are not the feature that bypasses listening and learning. BackboneFast is a legacy convergence enhancement for indirect link failures, not an edge-port feature. Cisco CCNA 200-301 v1.1 Network Access tests PortFast because it directly affects host startup, DHCP behavior, and access-layer convergence. The phrase ' immediately places ports in the forwarding state ' points directly to PortFast. The correct answer is B.
