When configuring VLAN trunking between a Cisco switch and a third-party switch, use IEEE 802.1Q. It is the open standard for VLAN tagging on Ethernet trunks. Cisco ISL was Cisco-proprietary and is obsolete on modern platforms. IEEE 802.1p relates to Class of Service marking inside the Ethernet header, not trunk encapsulation for interswitch VLAN transport. DSCP is an IP-layer QoS marking, not a Layer 2 VLAN trunking method. Cisco CCNA 200-301 v1.1 Network Access expects candidates to know that 802.1Q inserts a VLAN tag so multiple VLANs can traverse one physical trunk link. The native VLAN is carried untagged by default, while other VLANs are tagged. In multivendor networks, standards-based encapsulation is mandatory. Therefore, the action is to configure IEEE 802.1Q. The correct answer is B.

The correct response is D. The listed choice that matches FHRP operation is the exchange of multicast hello messages between routers. Those hello messages let routers negotiate active, standby, master, or backup roles for a shared default-gateway function. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. The better conceptual purpose is gateway redundancy, but among these options the multicast hello behaviour is the FHRP-specific answer. 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.

The verified answer is A and D. Automation improves network management by collecting data for baselines and onboarding new devices with less manual work. In SDN and controller-based environments, telemetry and automated workflows reduce repetitive CLI work and improve consistency. Cisco CCNA 200-301 v1.1 places this skill in Automation and Programmability, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. The answer set overstates AI prevention and proprietary APIs; useful automation is mainly repeatable provisioning, validation, telemetry, and analysis. 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.

To enable OSPFv2 on an active interface, the router needs an OSPF process and the interface must be placed into an OSPF area. The process ID is locally significant on the router; it starts the OSPF routing process but does not have to match the neighbor. The area ID is different: routers that form an adjacency on the same link must agree on the area, because the area defines the link-state database scope. Authentication keys, stub flags, and IPv6 addressing are not minimum requirements for OSPFv2. MD5 authentication can be added as a security control, but OSPFv2 can run without it. IPv6 belongs to OSPFv3, not OSPFv2. Cisco CCNA 200-301 v1.1 tests OSPFv2 under IP Connectivity, and the basic operational checklist is simple: active interface, matching network type/timers/area where required, and an enabled OSPF process. For this question, the two minimum configured parameters are the OSPF area and the OSPF process ID.

The root bridge election is based on the lowest bridge ID. The bridge ID includes priority and MAC address, with priority compared first. If priority values are not provided or are equal, the lowest MAC address becomes the tie-breaker. In the HQ LAN exhibit, Switch 3 has the lowest bridge ID value after the election criteria are applied, so Switch 3 becomes the root bridge. Cisco CCNA 200-301 v1.1 Network Access tests this because STP root placement determines which switch becomes the logical center of the Layer 2 topology. Once the root is selected, all nonroot switches calculate their root ports and designated ports based on path cost and tie-breakers. The physical drawing position of a switch is irrelevant. The root is chosen by numerical bridge ID comparison. The correct answer is C.

The correct response is A. The data plane forwards transit traffic by comparing the destination IP address to forwarding information. A router uses the routing table or FIB result to decide the outgoing interface and next hop for a packet. For Cisco CCNA 200-301 v1.1, the important point is the mechanism, not a generic description of the technology. Routing protocols, NETCONF configuration changes, and locally generated ICMP replies are control or management-plane activities. 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.

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.

To make a switch always win the STP root election for VLAN 750, configure the lowest possible bridge priority for that VLAN. Cisco STP priorities are configured in increments of 4096, and priority 0 is the lowest configurable value. The command spanning-tree vlan 750 root primary is convenient, but it calculates a priority intended to beat the current root at the time the command is entered. It is not as absolute as setting priority 0. Several listed numeric values are invalid or too high to guarantee root status. Cisco CCNA 200-301 v1.1 Network Access tests this because root bridge placement is a core switching design control. A switch becomes root by having the lowest bridge ID, and priority is compared before MAC address. Setting the VLAN priority to 0 gives the switch the strongest possible election position for VLAN 750. The command that best guarantees root status is spanning-tree vlan 750 priority 0.

The verified answer is A. WPA2 with AES is the strongest encryption combination in the listed options. AES/CCMP replaced older WEP, RC4, and TKIP-based approaches and is the expected secure WPA2 cipher choice. Cisco CCNA 200-301 v1.1 places this skill in Security Fundamentals, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. WEP and TKIP are deprecated, and WPA with AES is not the preferred WPA2 security combination. 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.

The verified answer is A. Traffic shaping smooths traffic by buffering excess packets and sending them later at a configured rate. That behaviour is used to reduce bursts and delay problems on slower links or provider handoffs, especially where sending faster than the downstream rate causes drops. Cisco CCNA 200-301 v1.1 places this skill in IP Services, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. Fair queuing is a congestion management method, policing drops or remarks excess traffic, and marking only identifies traffic classes. 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.

The verified answer is C. A Layer 2 switch floods an unknown unicast frame when the destination MAC address is missing from its MAC address table. The flood is limited to ports in the same VLAN and excludes the ingress port where the frame arrived. 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. The switch does not drop the frame immediately, send it back out the receiving port, or wait for the aging timer to expire. 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.

Routers choose the route with the longest matching prefix before comparing protocol preference for equally specific routes. If the RIP entry contains the longest prefix that includes destination 192.168.12.16, that route is selected even though RIP has a worse administrative distance than OSPF or EIGRP. Administrative distance only becomes the deciding factor when competing routes describe the same prefix length. Cisco CCNA 200-301 v1.1 IP Connectivity repeatedly tests this rule because it is fundamental to forwarding decisions. The router does not load-balance among routes simply because multiple protocols know related networks. It also does not choose EIGRP solely because EIGRP has a lower administrative distance when another route is more specific. The forwarding lookup starts with the destination IP address and finds the most specific matching prefix in the routing table. In this exhibit, the RIP route is the longest prefix inclusive of 192.168.12.16, so A describes the router behavior correctly.

The correct answer is C: AES-128. Cisco’s WPA2 documentation describes WPA2 as using AES with CCMP; AES Counter Mode encrypts 128-bit blocks with a 128-bit encryption key. The existing answer of AES-256 confuses PSK material or hexadecimal key-entry length with the actual WPA2 CCMP encryption cipher. WPA2-Personal uses a pre-shared key for authentication/key derivation, but the data-protection mechanism is AES-CCMP, not RC4, TKIP with RC4, or plain RC4. TKIP was associated with WPA and is considered legacy; WEP and RC4-based approaches are not acceptable modern wireless protection. CCNA 200-301 v1.1 Network Access expects the basic security pairing: WPA2 uses AES/CCMP, and WPA3 improves authentication with SAE. Because the option set forces a key-size distinction, Cisco’s WPA2 configuration reference supports AES-128. Reference: Cisco WPA2 configuration example describing AES Counter Mode and a 128-bit encryption key.

JSON is commonly used to describe structured data and it supports arrays. A JSON object is written as name-value pairs enclosed in braces, while an array is an ordered list enclosed in brackets. This makes JSON compact and easy for REST APIs, scripts, controllers, and network automation tools to exchange data. Cisco CCNA 200-301 v1.1 includes JSON because network programmability often requires reading API responses from systems such as Cisco DNA Center or device controllers. Option A describes markup-style languages such as XML or HTML, which use angle brackets and tags. Option D is backwards because XML is usually more verbose than JSON. Option C is too vague; JSON can be stored, but the defining exam feature here is its structured representation, including arrays. A fast way to recognize JSON is to look for curly braces, quoted keys, colons between keys and values, and square brackets when multiple values are grouped.

A notice-level syslog message is severity level 5. It reports normal but significant conditions, such as operational state changes that an engineer should know about even when the device is not in a critical failure state. An interface line changing status is a standard example of a significant network event: it can affect reachability, routing adjacencies, and user traffic, but it is not necessarily a severity 0 emergency or severity 1 alert. Cisco CCNA 200-301 v1.1 includes syslog under IP Services because engineers must understand logging destinations and severity levels. A TCP connection teardown or ICMP connection being built is not the typical Cisco device notice-level management event tested here. A certificate expiration may be security-related and can be logged at various severities depending on platform and feature. The simple exam mapping is that notice means noteworthy state change. An interface line status change fits that definition, so C is the best answer.

When two routing protocols advertise a route to the same destination, the router first compares administrative distance. Administrative distance is Cisco IOS’s trust value for the source of routing information. A lower AD is preferred over a higher AD, so an EIGRP internal route with AD 90 is preferred over an OSPF route with AD 110, and both are preferred over a RIP route with AD 120. Metrics are compared only among routes learned from the same routing protocol, not across different protocols. Hop count is a specific metric used by RIP, and DUAL is the algorithm used by EIGRP, not the cross-protocol decision mechanism. This is a core CCNA 200-301 v1.1 IP Connectivity rule: longest prefix match chooses the most specific route first, and administrative distance decides between different routing information sources for the same prefix. Therefore the verified answer is C. Reference: Cisco IOS route selection and administrative distance behavior.

JSON represents data as structured name/value pairs, arrays, objects, strings, numbers, Booleans, and null values. In the exhibit, Option C is the output that follows JSON syntax: field names are enclosed in double quotes, values appear after colons, and objects or arrays are delimited with braces or brackets. XML would use opening and closing tags. YAML normally relies on indentation and key-value formatting without the same heavy brace structure. Plain text or CLI output does not follow a strict object model. Cisco CCNA v1.1 Automation and Programmability includes recognizing data formats used with APIs and automation tools. That is the practical reason JSON appears so often in controller-based networking and REST APIs: it is compact, structured, and easy for software to parse. The key exam check is visual. If you see quoted keys, colons, braces, brackets, and comma-separated values arranged as objects or arrays, you are looking at JSON.

OpenFlow and NETCONF are southbound interfaces because they are used between a controller or automation system and network devices. Southbound APIs carry instructions toward the infrastructure: switches, routers, and other forwarding devices. OpenFlow is the classic SDN example because it lets a controller influence forwarding behavior in network devices. NETCONF is also a southbound management protocol; it uses structured XML-based remote procedure calls to retrieve or modify device configuration and operational data. Thrift and CORBA are general distributed-computing technologies, not the CCNA-standard southbound networking answers here, and DSC is not a normal Cisco SDN southbound API in this context. Cisco CCNA v1.1 automation objectives expect the candidate to separate northbound and southbound communication. Northbound APIs face applications and orchestration systems. Southbound APIs face the managed network devices. Because both OpenFlow and NETCONF operate on the controller-to-device side, A and B are the correct selections.

Cisco DNA Center is more extensible than traditional device-by-device campus management because it exposes APIs and integration points. REST APIs allow external applications and automation systems to interact with Cisco DNA Center programmatically instead of relying only on manual GUI or CLI workflows. SDKs extend the platform model by helping integrate third-party network devices and applications where supported. This is fundamentally different from logging into each switch with SSH and pasting commands. Adapters that support every IOS family are not the central extensibility answer, and customized product versions by enterprise size are not what the question asks. Modular design may describe software architecture generally, but the explicit extensibility capabilities tested by Cisco are APIs, adapters, and SDKs. Cisco CCNA v1.1 Automation and Programmability includes controller-based networking, REST APIs, and Cisco DNA Center. The exam logic is direct: extensibility means outside systems can interact with and build on the controller platform. REST APIs and third-party SDK support provide that ability.

Use A for this item. IPv6 compression removes leading zeros in each hextet and compresses one longest contiguous run of zero hextets with double colon. The address 2001:0db8:0000:0000:0700:0003:400F:572B becomes 2001:db8::700:3:400F:572B. 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. The double colon cannot be used twice, and nonzero hextets such as 400F cannot be shortened to 4F. 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.
