  1. Question 1IP Connectivity

    What is the purpose of a default route (0.0.0.0/0) in a routing table?

    ATo block all traffic
    BTo forward packets to a next hop when no more specific route matches the destination — the 'gateway of last resort'
    CTo route traffic to the loopback interface
    DTo enable DHCP

  3. Question 3IP Connectivity

    A router has the following routes in its routing table: - 10.1.0.0/16 via 192.168.1.1 - 10.1.1.0/24 via 192.168.1.2 - 10.1.1.128/25 via 192.168.1.3 A packet arrives destined for 10.1.1.200. Which next-hop will the router use?

    A192.168.1.1
    B192.168.1.2
    C192.168.1.3

  4. Question 4IP Connectivity

    What happens when a router cannot find a matching entry in its routing table for a destination IP address and no default route exists?

    AThe router floods the packet out all interfaces
    BThe router drops the packet and may send an ICMP Destination Unreachable message to the source
    CThe router buffers the packet indefinitely until a route appears
    DThe router sends the packet to the first interface in its configuration

  9. Question 9IP Connectivity

    If a router learns the same destination via OSPF (AD 110) and EIGRP (AD 90), which route is installed?

    AOSPF (lower number always loses)
    BEIGRP — lower administrative distance (90) is preferred over OSPF (110), indicating higher trustworthiness
    CBoth routes are installed for load balancing
    DThe route learned first

CCNA Routing Exam Tips

IP Routing & Protocols questions in CCNA are typically scenario-based. Focus on network fundamentals, IP connectivity, security basics, and automation concepts. Priority concepts: routing, ospf, static route, default route, administrative distance, routing table.

What CCNA Expects

  • Anchor your answer in choose the configuration that correctly applies to the described network topology and requirements.
  • Routing scenarios for CCNA are frequently mapped to Domain 3 (25%), so read the objective carefully before picking controls or architecture.
  • Expect multi-topic scenarios where Routing interacts with routing, switching, security, or automation patterns rather than appearing as an isolated question.
  • When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Associate) and vendor best practices.

High-Value Routing Concepts

  • Know the core Routing building blocks cold: routing, ospf, static route, default route.
  • Review the edge-case features and limits for administrative distance, routing table; these details are commonly used to differentiate answer choices.
  • Practice service-integration reasoning: how Routing pairs with IP Addressing, OSPF, Inter-VLAN Routing in real deployment patterns.
  • For CCNA, explain why the chosen Routing design meets reliability, security, and cost expectations better than the alternatives.

Common CCNA Traps

  • Watch for confusing similar protocols or mixing Layer 2 and Layer 3 behavior.
  • Questions in IP Connectivity often include distractors that look correct for Routing but violate security policy, convergence, or redundancy requirements.
  • Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
  • If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.

Fast Review Checklist

  • Can you compare at least two Routing implementation paths and justify which one best fits the scenario?
  • Can you map the chosen answer back to IP Connectivity (25%) outcomes for CCNA?
  • Can you explain security and access boundaries for Routing without relying on default-open assumptions?
  • Can you describe how Routing integrates with IP Addressing and OSPF during failure, scaling, and monitoring events?
