The correct command is ipv6 address 2001:DB8:5:112::/64 eui-64. The wording says the address is generated from a specified IPv6 prefix and the interface MAC address. That is exactly what the eui-64 keyword does: it derives the 64-bit interface identifier from the MAC address and combines it with the configured /64 prefix. The ipv6 address autoconfig command also can create an address, but it learns the prefix from Router Advertisement messages through SLAAC; the prefix is not explicitly specified in the command. DHCPv6 would request addressing information from a DHCPv6 server, and the link-local option shown is not a global unicast address built from the stated prefix. Cisco CCNA v1.1 Network Fundamentals includes IPv6 address types and address configuration methods, and this question tests precise IOS syntax. When the prefix is typed in the command and the MAC-derived interface ID is required, choose the static EUI-64 form, not autoconfig.

Cisco REST APIs commonly encode request and response payloads using JSON or XML. JSON is lightweight, easy for applications to parse, and widely used in modern network automation. XML is also common in Cisco controller and device APIs, especially in platforms that historically exposed XML documents or models. EBCDIC is a character encoding, not a REST API payload method. SGML is a markup-language ancestor and is not the normal format for Cisco REST API payloads. YAML is popular in automation tools such as Ansible, but this question asks which encoding methods are supported by REST APIs in the Cisco context shown by the references. Under CCNA 200-301 v1.1 Automation and Programmability, candidates must recognize JSON and XML as structured data formats used by APIs. Therefore the verified answers are B and E. Reference: Cisco APIC and Cisco REST API documentation describing JSON and XML payload support.

Answer D is the technically correct selection. REST uses HTTP messages to transfer data between clients and applications on different hosts. RESTful APIs commonly use HTTP methods such as GET, POST, PUT, PATCH, and DELETE with JSON or XML payloads. 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. OpenFlow is a southbound SDN protocol, while OpenStack and OpFlex solve different infrastructure and policy problems. 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.

This drag-and-drop item maps common Layer 2 and access-layer threats to their mitigation controls. Dynamic ARP Inspection protects against ARP spoofing or poisoning by validating ARP packets against trusted binding information. DHCP snooping blocks rogue DHCP behavior and builds the binding table used by other protections. BPDU Guard protects PortFast edge ports by err-disabling a port that receives an unexpected spanning-tree BPDU, which helps prevent rogue switch insertion. A nondefault or unused native VLAN, combined with disabling DTP and manually configuring trunks, reduces VLAN hopping exposure. Cisco CCNA 200-301 v1.1 Security Fundamentals and Network Access both touch these controls because many campus attacks happen before traffic ever reaches a firewall. The dependable way to solve the matching is to identify the abused protocol: ARP attacks map to DAI, DHCP attacks map to DHCP snooping, unexpected switch/STP participation maps to BPDU Guard, and trunk/native-VLAN abuse maps to VLAN-hopping mitigation.

SNMP is the protocol associated with IOS MIB access and centralized network management. The Management Information Base is the structured set of managed objects that an SNMP manager can query or, where permitted, modify on an SNMP agent. In the context of backing up many router configurations globally, SNMP can be used by management software to interact with Cisco IOS MIB objects and trigger configuration-copy operations. CDP discovers directly connected Cisco neighbors; it is not a configuration backup protocol. SMTP is for mail transfer. ARP resolves IPv4 addresses to MAC addresses on a local segment. Cisco CCNA v1.1 IP Services includes device management protocols such as SNMP, syslog, and NTP. The important distinction is scope: SNMP gives a management station structured visibility and control through MIB objects across many devices. That is why the Cisco IOS MIB clue points directly to SNMP.

The working routing table already shows a primary default route over the primary circuit. To establish failover, the backup path must be installed as a floating static route: a static route with the same destination but a higher administrative distance than the primary static route. Option B adds default routes through the secondary-circuit next hops and sets the administrative distance to 2. Because a normal static route has an administrative distance of 1, the router keeps the primary route in the routing table while it is reachable. If the primary next hop or exit path becomes unavailable, the route with AD 2 is then selected and traffic moves to the secondary circuit. The host-specific route options do not provide general default-route failover for all traffic, and a second default route without a higher administrative distance could create unwanted equal-cost forwarding. CCNA 200-301 v1.1 expects this distinction under static routing and IP Connectivity. Reference: Cisco static route and floating static route behavior.

Answer D is the technically correct selection. Virtual machines are operating system instances decoupled from the physical server hardware. The hypervisor presents virtual CPU, memory, disk, and NIC resources so multiple VMs can run on one host. 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. The VM does not manage host resources itself, and the physical server can run multiple OS instances concurrently through virtualization. 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.

DNS lets applications use names instead of forcing users and software to work directly with IP addresses. A client can ask for the address associated with a hostname, and DNS returns the resource records needed to reach that service. DNS can also map one name to multiple IP addresses, which supports simple distribution, redundancy, or service design depending on the record type and client behavior. It does not encrypt WAN traffic by default, and it does not secure IP addresses merely by hiding them behind fully qualified domain names. DNS is hierarchical, not flat, which is why the root, top-level domains, authoritative zones, and host records can scale globally. Cisco CCNA 200-301 v1.1 covers DNS under IP Services because name resolution is required for many network operations, including management access, web services, and application connectivity. The two valid roles here are enabling applications to identify resources by name and allowing a hostname to be associated with more than one IP address.

TCP and UDP both include checksums, but TCP adds reliability mechanisms that UDP does not provide. TCP uses acknowledgments so the sender knows what data arrived, retransmissions when data is lost, sequencing to put data back in order, and windowing to control the amount of outstanding data. UDP is deliberately simpler. It uses a checksum for error detection, but it does not establish a reliable session, acknowledge every segment, or retransmit lost data at the transport layer. Applications that use UDP can build their own recovery if they need it, but UDP itself does not guarantee delivery. Cisco CCNA 200-301 v1.1 Network Fundamentals expects this distinction to be automatic: TCP is connection-oriented and reliable; UDP is connectionless and best-effort. The other answer choices introduce parity checks or CRC as transport reliability methods, which is not the TCP/UDP comparison being tested. The correct statement is that TCP uses checksum, acknowledgments, and retransmissions, while UDP uses checksums only.

The data plane is responsible for forwarding traffic. In traditional devices, the data plane is distributed across the network devices themselves, even when the control and management functions are centralized or influenced by a controller. The control plane decides paths and builds tables; the data plane uses those tables to switch or route packets. The management plane handles configuration, monitoring, and administrative access. A policy plane may describe intent or business policy in some architectures, but it is not the forwarding plane. Cisco CCNA 200-301 v1.1 Automation and Programmability tests software-defined architecture at a conceptual level. The most important separation is that controller-based networking can centralize control while forwarding still occurs on the devices. The plane that is distributed and responsible for traffic forwarding is the data plane. Therefore, D is correct.

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.

The correct response is the displayed drag-and-drop mapping. Network architecture characteristics distinguish two-tier, three-tier, spine-leaf, WAN, SOHO, and cloud designs. The correct mapping depends on where devices attach, where aggregation occurs, how redundancy is built, and whether the design optimizes campus access, data-center east-west traffic, or remote connectivity. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. The distractors normally mix access, distribution, core, and data-center terms, so matching function to layer is the safest method. 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.

HSRP gives hosts a resilient default gateway by using a virtual IP address shared by a group of routers. One router is elected active and forwards traffic sent to the virtual gateway; another router waits as standby and takes over if the active router fails. The hosts do not need to know which physical router is active. They continue to use the same default gateway address. That is the central first-hop redundancy model Cisco expects CCNA candidates to understand. HSRP does not synchronize full router configurations, and it does not make every router use the same physical interface address. It also does not inherently load-balance all gateway traffic; classic HSRP is active/standby per group, although designs can use multiple groups for load sharing. The predictable HSRP behaviors are election of active and standby routers, plus use of a shared virtual IP address as the LAN default gateway. Therefore, B and D are the valid choices.

A Wireless LAN Controller manages lightweight access points by exchanging control traffic with them. Older Cisco controller deployments used LWAPP, while modern deployments use CAPWAP, but the intent of the answer is the controller-to-lightweight-AP communication function. The WLC is not an AP itself and does not register with a single AP that controls the network. SSIDs identify WLANs for clients, but simply using SSIDs is not the defining WLC function. Monitoring wired LAN activity is not the best description either. Cisco CCNA 200-301 v1.1 Network Access expects candidates to understand the controller-based wireless model: lightweight APs depend on the controller for centralized management, configuration, and policy. The controller sends and receives control-plane messages with APs so wireless services can be coordinated at scale. Within the available choices, sending LWAPP packets to access points is the function that identifies a WLC.

Internet-bound traffic normally uses the default route when no more specific route matches the destination. In an IPv4 routing table, the default route is 0.0.0.0/0. The /0 prefix means it matches every IPv4 destination, but only after the router fails to find a more specific match. That matters: routers do not simply use the default route first. They perform longest-prefix matching, so connected, static, OSPF, EIGRP, or other learned specific routes win before 0.0.0.0/0 is considered. Cisco CCNA 200-301 v1.1 IP Connectivity expects engineers to distinguish host routes, network routes, floating static routes, and default routes. Here, the wording asks which path is used for Internet traffic, not traffic to a listed internal subnet. The available answer that represents a catch-all Internet path is 0.0.0.0/0. The other prefixes are specific networks and cannot represent all unknown destinations. Therefore, C is the correct choice.

The correct response is B. For 2.4-GHz Wi-Fi, the standard nonoverlapping channel plan uses channels 1, 6, and 11. Adjacent APs should be placed on nonoverlapping channels to reduce co-channel and adjacent-channel interference. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. Grouping nearby APs on the same channel or physically adjacent overlapping channels increases contention and lowers performance. 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.

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.

Spanning Tree elects the root bridge by comparing bridge IDs. The bridge ID is made from the bridge priority, the extended system ID, and the switch MAC address. The lowest bridge ID wins. If one switch has a lower priority than the others, it becomes root regardless of MAC address. If priorities are equal, the lowest MAC address breaks the tie. In this exhibit, SW3 has the best root-bridge election value, so it becomes the root bridge. Cisco CCNA 200-301 v1.1 Network Access expects engineers to be comfortable reading STP election data because the root placement affects forwarding paths and blocked ports. The decision is not based on physical position in the diagram, interface speed alone, or switch name. It is a deterministic comparison of STP identifiers. Once the root bridge is elected, every nonroot switch selects its root port based on lowest path cost toward that root. The elected root for this configuration is SW3.

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.

Use B for this item. A SOHO network commonly lets multiple users share one broadband Internet connection. Small office/home office designs emphasize low cost, simple management, wireless and wired access, and Internet edge services in a compact topology. In Cisco CCNA 200-301 v1.1, Network Fundamentals 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. Full-mesh switching, thousand-user capacity, and three-tier redundancy describe larger enterprise designs. 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.
