CCNA Routing & Switching 200-301 Practice Exam Questions

Based on the list of topics you've provided, it looks like you're preparing for a comprehensive understanding of networking fundamentals, with a focus on Cisco technologies. Here's a brief explanation and guidance on each topic to help you study and understand these concepts:

1. Basic Operations:

   • Root port, root bridge (primary/secondary), and other port names: In an STP-enabled network, the root port is the port on a switch that has the best path to the root bridge. The root bridge is the device that has the lowest bridge ID and acts as the master in determining the topology of the network.
   • Port states (forwarding/blocking): STP also defines port roles such as Disable, Blocking, Listening, Learning, Forwarding, etc. The Forwarding state means the port is actively forwarding frames.
   • PortFast benefits: PortFast allows a port to transition directly from blocking to forwarding (bypassing listening and learning states) to prevent delays in connecting a host to the network.

2. Wireless LAN Components:

   • Compare Cisco Wireless Architectures and AP modes: There are different wireless architectures like Controller-based (Catalyst 9K access points with a WLAN controller) and Controller-less (Lightweight Access Points). AP modes include Station (client), Ironframe (AP as a controller for local switch access), and Autonomous.
   • Physical infrastructure connections of WLAN components: APs connect to switches via access ports, which can be in a trunk or access mode depending on the network design. WLAN Controllers connect to switches or directly to APs through management ports. LAG (Link Aggregation Group) is used for high availability and increased bandwidth.
   • Management access connections: These include protocols like Telnet, SSH, HTTP, HTTPS, console connections, and authentication protocols like TACACS+/RADIUS for enhanced security.

3. Wireless LAN Access Configuration:

   • Configure the components of a wireless LAN access for client connectivity: This involves setting up the AP with an SSID, security protocols (like WPA2), and proper channel planning.

4. Routing Table Interpretation:

   • Components of a routing table: Understand what each field in the routing table represents: route, prefix, network mask, next hop, administrative distance, metric, gateway of last resort, etc.

5. Static and Dynamic Routing:

   • Configure and verify IPv4 and IPv6 static routing: Static routes are manually configured routes that the router uses to forward traffic.
   • Default route, Network route, Host route, Floating static: These are different types of static routes used in a network for various purposes.

6. OSPFv2 Configuration and Verification:

   • Single area OSPFv2: Configure OSPF in a single area, ensure neighbor adjacencies, and verify the operation.
   • Point-to-point vs. Broadcast (DR/BDR selection): Point-to-point is used for direct links between two routers, while broadcast is used in a multi-access network where a Designated Router (DR) and Backup Designated Router (BDR) are elected.

7. First Hop Redundancy Protocol:

   • Describe the purpose of first hop redundancy protocol: It provides resilience at the first hop by preventing routing adjacency from failing during a switchover or network partition event.

8. IP Services Configuration and Verification:

   • NTP operating in a client and server mode: NTP synchronizes the clock of network devices to ensure accurate timestamps for logs, authentication, etc.
   • DHCP and DNS within the network: DHCP provides automatic configuration of devices on the network, while DNS translates domain names into IP addresses.

9. Campus Device Management:

   • Compare traditional campus device management with Cisco DNA Center enabled device management: Cisco DNA Center provides a centralized platform for managing and automating the entire network lifecycle using APIs, templates, and analytics.

10. APIs and Configuration Management:

    • REST-based APIs (CRUD, HTTP verbs, data encoding): RESTful APIs use the CRUD operations (Create, Read, Update, Delete) and HTTP methods (GET, POST, PUT, DELETE) for network automation.
    • Configuration management mechanisms (Puppet, Chef, Ansible): These tools automate the configuration of devices by using scripts or policies to ensure consistent configurations across a network.

11. JSON Encoded Data Interpretation:

    • Interpret JSON encoded data: JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate.

Remember, while studying these topics, it's crucial to have hands-on experience with Cisco devices and software. Use Cisco Packet Tracer or real equipment to practice configurations and troubleshoot issues. Additionally, always refer to the latest Cisco documentation and official exam objectives for the most accurate and relevant study material.
