  • IP Addressing (IPv4, IPv6): Understand address structure, allocation methods, and transition mechanisms. You must be able to design addressing schemes for both IPv4 and IPv6 networks and identify compatibility issues in mixed environments.
  • Subnetting: Master subnet calculation, CIDR notation, and variable-length subnet masking (VLSM). Apply subnetting to optimize address space and plan network growth across multiple sites.
  • Routing Protocols (OSPF, BGP, RIP): Analyze how each protocol operates, when to deploy each, and how to configure them for specific network topologies. Understand convergence behavior, metric calculation, and failover scenarios in production networks.
  • Network Address Translation (NAT): Configure and troubleshoot static, dynamic, and PAT (Port Address Translation) scenarios. Recognize NAT limitations and apply it appropriately in hybrid and multi-vendor environments.
  • Network Security and Firewalls: Interpret firewall rules, access control lists (ACLs), and stateful inspection concepts. Apply security best practices to protect network resources without compromising performance.
  • Network Troubleshooting: Use diagnostic tools and methodologies to isolate and resolve connectivity, routing, and performance issues. Interpret logs, packet captures, and system alerts to identify root causes quickly in operational networks.
  • Ericsson IP Networking Products and Solutions: Recognize Ericsson-specific platforms, their roles in network architecture, and how to integrate them with standard IP networking practices. Understand product-specific configuration paradigms and operational workflows.

Question Formats & What They Test

The ECP-206 exam uses a mix of question types to assess both foundational knowledge and applied reasoning in real-world network scenarios.

  • Multiple choice: Test recall of definitions, protocol behaviors, feature capabilities, and best practices. Questions focus on identifying correct terminology and understanding when specific technologies apply.
  • Scenario-based items: Present realistic network situations and ask you to choose the best configuration, troubleshooting step, or design decision. These require you to connect multiple concepts and reason through trade-offs.
  • Configuration analysis: Show partial configurations or command outputs and ask you to identify errors, predict outcomes, or recommend corrections. These test practical understanding of how settings affect network behavior.

Questions progress in difficulty and emphasize practical application over memorization, reflecting the skills needed in operational roles.

Preparation Guidance

Effective preparation requires a structured approach that spreads study across all topics and builds from foundational concepts to scenario-based reasoning. Allocate 4-6 weeks for thorough preparation, with each week focused on specific topic clusters and progressive practice.

  • Map topics to weekly goals: Week 1-2 cover IP Addressing and Subnetting fundamentals; Week 3 focus on Routing Protocols; Week 4 add NAT and Security; Week 5 concentrate on Troubleshooting and Ericsson products; Week 6 integrate all topics through scenario practice.
  • Practice question sets regularly and review explanations for every incorrect answer to identify knowledge gaps and reinforce correct reasoning patterns.
  • Connect features across workflows: understand how addressing decisions affect routing configuration, how NAT impacts security rules, and how troubleshooting tools help validate design choices.
  • Complete a timed mini mock exam in the final week to build pacing confidence, identify remaining weak areas, and reduce test-day anxiety.

Frequently Asked Questions

Which topics carry the most weight on the ECP-206 exam?

Routing Protocols, Network Troubleshooting, and IP Addressing typically account for a larger portion of exam items. However, all topics are important because they interconnect in real networks; weak knowledge in any area can affect your ability to answer scenario-based questions correctly.

How do IP Addressing, Subnetting, and Routing Protocols connect in real project workflows?

Addressing and subnetting decisions define your network topology and determine which routes are needed. Routing protocols then distribute reachability information based on that topology. In practice, you design addresses first, then select and configure routing protocols to match your addressing scheme and redundancy requirements.

How much hands-on experience helps, and which labs should I prioritize?

Hands-on experience is valuable for building intuition about how configurations affect behavior. Prioritize labs that let you configure basic IP addressing, set up OSPF or BGP in a multi-router topology, apply NAT rules, and use troubleshooting tools like ping, traceroute, and packet capture to validate your changes.

What common mistakes lead to lost points on ECP-206?

Candidates often confuse when to use each routing protocol, misunderstand NAT behavior with overlapping address spaces, and overlook security implications of their design choices. Another frequent error is misinterpreting subnet masks or CIDR notation under time pressure. Review these areas carefully and practice converting between different notation formats.

What is the best strategy for the final week before the exam?

In the final week, shift from learning new material to reinforcing weak areas and building test-taking rhythm. Take a full-length practice test under exam conditions, review all incorrect answers, and do brief daily refreshers on topics that gave you trouble. Avoid cramming new content; focus instead on confidence and pacing.

Question No. 1

What is the maximum number of unique VLAN IDs available?

Show Answer Hide Answer
Correct Answer: C

The maximum number of unique VLAN IDs available is 4096. A VLAN ID is a 12-bit identifier that can range from 0 to 4095.However, VLAN ID 0 is reserved for tagging the priority of frames and VLAN ID 4095 is reserved for implementation use, so only VLAN IDs from 1 to 4094 are available for user configuration78. VLAN IDs are used to identify different broadcast domains or subnets on a Layer 2 network. VLAN IDs are carried in the IEEE 802.1Q tag in the Ethernet frame header.


Question No. 2

Which statement is true about LDP?

Show Answer Hide Answer
Correct Answer: C

LDP relies on IGP for all routing-related decisions. LDP is a protocol that distributes labels in an MPLS environment, but it does not perform any routing functions. LDP uses the underlying routing information provided by an IGP, such as OSPF or IS-IS, to forward label packets. LDP and IGP do not exchange their databases at regular intervals, but rather use hello messages to maintain adjacencies and sessions.Reference:Ericsson IP Networking - Routing Protocols,Label Distribution Protocol - Wikipedia


Question No. 3

Which two statements are true about the Ericsson Router 6000 series? (Choose two.)

Correct Answer: A, D

Two statements that are true about the Ericsson Router 6000 series are:

The Router 6000 uses the same building practice and accessories as the Ericsson Radio System. The Ericsson Radio System is a modular and scalable radio access network solution that supports multiple standards, bands, and layers. The Router 6000 series is fully integrated into the Ericsson Radio System, using the same building practice and accessories such as mounting kits, cables, power supplies, etc.This simplifies installation, operation, and maintenance of both radio and transport equipment78.

The Router 6000 products range from all-outdoor small site routers to large aggregation routers. The Router 6000 series consists of three main products: the Router 6672 for access, the Router 6675 for pre-aggregation, and the Router 6274 for metro aggregation. The Router 6672 is an all-outdoor small cell site router with high-capacity and low-power consumption. The Router 6675 is a combined access and E-RAN switch with hardware-accelerated IPSec and high-accuracy internal clock.The Router 6274 is a high-capacity metro aggregation router with SDN functionality and flexible interface options78.


Question No. 4

Which two features does IPsec provide? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, D

IPsec provides two main features: protecting packets from modification and hiding the content of packets from observation. IPsec protects packets from modification by using cryptographic algorithms to generate and verify message authentication codes (MACs) or digital signatures for each packet. These mechanisms ensure that the packets have not been tampered with or altered in transit by unauthorized parties. IPsec hides the content of packets from observation by using encryption algorithms to scramble the payload of each packet.This prevents eavesdroppers or interceptors from reading or analyzing the data carried by the packets12.


Question No. 5

Based on industry standard practice, what is the correct order of DiffServ priority (highest to lowest) for the DiffServ classes: Default Forwarding (DF), Network Control (NC), Assured Forwarding (AF), and Expedited Forwarding (EF)?

Show Answer Hide Answer
Correct Answer: A

The correct order of DiffServ priority (highest to lowest) for the DiffServ classes: Default Forwarding (DF), Network Control (NC), Assured Forwarding (AF), and Expedited Forwarding (EF) is EF, NC, AF, DF. DiffServ is a QoS model that classifies and prioritizes traffic into different service classes based on the DSCP field in the IP header. The DSCP field is a 6-bit field that can encode up to 64 different per-hop behaviors (PHBs). The DiffServ classes are predefined groups of PHBs that have similar characteristics and requirements. The four main DiffServ classes are:

EF: This class provides the highest priority and lowest delay for real-time applications such as voice and video.The DSCP value for EF is 101110 or 46 in decimal12.

NC: This class provides the second highest priority and low delay for network control traffic such as routing protocols and network management.The DSCP value for NC is 110000 or 48 in decimal12.

AF: This class provides four levels of assured forwarding with different drop probabilities for each level. AF is suitable for applications that require guaranteed bandwidth and delivery assurance, such as web browsing and email.The DSCP values for AF range from 001010 to 011110 or 10 to 46 in decimal12.

DF: This class provides the lowest priority and best-effort service for applications that can tolerate packet loss and delay, such as file transfer and backup.The DSCP value for DF is 000000 or 0 in decimal12.
