Dynamic routing is a critical concept in modern networking, especially for IT professionals preparing for certification exams like Cisco CCNA, CompTIA Network+, and other networking-focused credentials. A common style of questioning in these exams is to “match the dynamic routing protocol component to the characteristic. (not all options are used.)” — a format that tests both your conceptual understanding and memory.
This blog from DumpsQueen Official is designed to walk you through each major component of dynamic routing protocols, their unique characteristics, and why this matching-style question format appears so often in networking exams. You'll also get MCQ-style sample questions at the end, along with tips on how to approach such exam formats using quality Exam Prep Dumps and Study Guide material.
Understanding Dynamic Routing Protocols
Dynamic routing protocols enable routers to discover remote networks, determine the best path, and adjust routing tables automatically when changes occur in the topology. Unlike static routing, dynamic routing is more scalable and responsive to network changes.
Why "Match the Component to the Characteristic" Format Matters
This question type forces you to:
- Understand how routing protocols behave
- Know specific components like metrics, algorithms, update methods
- Recognize the difference between protocols (RIP, EIGRP, OSPF, BGP, etc.)
Hence, it's more than memorization — it’s about associative learning, a key focus of most certification tests.
Key Dynamic Routing Protocol Components and Their Characteristics
Let’s walk through the most frequently used components and their matching characteristics:
1. Metric
- What it does: Determines the best path when multiple routes exist.
- Example: RIP uses hop count; OSPF uses cost based on bandwidth.
2. Administrative Distance (AD)
- What it does: Ranks the trustworthiness of routing sources.
- Example: Directly connected = 0, Static = 1, OSPF = 110, RIP = 120.
3. Convergence Time
- What it does: Measures how quickly a network adapts to changes.
- Protocols: EIGRP and OSPF have faster convergence than RIP.
4. Routing Algorithm
- What it does: Determines how routes are calculated.
- Types: Distance-vector (RIP), Link-state (OSPF), Path-vector (BGP).
5. Hello Packets
- What it does: Used to establish and maintain neighbor relationships.
- Protocol Usage: Common in OSPF and EIGRP.
6. Topology Table
- What it does: Holds all possible routes learned from neighbors.
- Protocol Usage: Exclusive to EIGRP.
7. Neighbor Table
- What it does: Tracks all directly connected routers.
- Protocol Usage: Used in EIGRP and OSPF.
8. Routing Table
- What it does: Contains the best routes to each network destination.
- Protocol Usage: Final destination for learned routes in all protocols.
Matching Tips for Certification Exams
When facing the “match the dynamic routing protocol component to the characteristic. (not all options are used.)” question format, follow this structured approach:
- Eliminate what you know is incorrect
- Focus on matching distinctive features first. For instance, “Hello packets” won’t match with BGP or RIP, so eliminate those.
- Look for protocol-specific vocabulary
- Words like “topology table” or “feasible distance” are specific to EIGRP.
- Use acronyms and memory aids
- For example, remember AD values using: "Directly connected (0), Static (1), EIGRP (90), OSPF (110), RIP (120)"
- Practice through quality resources
- Rely on trusted Exam Prep Dumps and Study Guide material like those offered by DumpsQueen to reinforce your understanding.

Components Often Misunderstood in Matching Questions
Let’s take a deeper look at components that often confuse test-takers:
a. Feasible Distance and Reported Distance (EIGRP)
- Feasible Distance: Lowest calculated cost to a destination
- Reported Distance: Cost as advertised by a neighbor
These are common distractors in matching questions. Make sure you're clear on their definitions.
b. DR/BDR Roles (OSPF)
- DR (Designated Router) and BDR (Backup DR) are elected in multi-access networks
- Their function is to reduce network traffic by centralizing LSAs
You might be asked to match “minimizes LSA flooding” to “Designated Router”.
c. Timers
- Hello Timer: Time between hello packets
- Hold Timer: Maximum time to wait before declaring a neighbor down
Often used in matching for RIP and EIGRP questions.
Real-World Use: Why Knowing This Matters
Network professionals must configure and troubleshoot routing protocols in real time. Misunderstanding the role of a component like “Metric” or “Convergence” can lead to inefficient routing decisions and network downtime.
In job interviews, hiring managers may pose real-life scenarios, indirectly referring to components like “administrative distance” to test your routing knowledge.
