200-301 Exam Dumps - Implementing and Administering Cisco Solutions (200-301 CCNA) v1.1

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.

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.

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.

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.

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.

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.

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.

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.
