QUESTION: 27

A BGP route reflector in the network is taking longer than expected to converge during large network changes. Troubleshooting shows that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune the device performance?

Decrease the size of the small buffers.
Increase the size of the large buffers.
Increase the keepalive timers for each BGP neighbor.
Increase the size of the hold queue.

Answer(s): D

Explanation:

The hold queue is a buffer that holds packets temporarily when the device's processing capacity is overwhelmed. In the given situation, the route reflector is experiencing delays during large network changes, indicating that it is struggling to handle the TCP acknowledgments during route updates. This suggests that the hold queue may be filling up quickly, causing congestion and delays in processing the acknowledgments.

By increasing the size of the hold queue, the router can accommodate a larger number of packets in the queue, reducing the likelihood of congestion and improving performance during route updates. This allows the router to handle a higher volume of TCP acknowledgments and facilitates faster convergence.

QUESTION: 28

Which two conditions must be met for EIGRP to maintain an alternate loop-free path to a remote network? (Choose two.)

The Reported Distance from a successor is higher than the local Feasible Distance.
A feasible successor must be present.
The Reported Distance from a successor is lower than the local Feasible Distance.
The Feasible Distance from a successor is lower than the local Reported Distance.
The feasibility condition does not need to be met.

Answer(s): B,C

Explanation:

A feasible successor must be present: A feasible successor is a neighboring router that satisfies the feasibility condition, which states that the advertised distance (Reported Distance) to a remote network from the neighboring router is less than the local router's feasible distance. The feasible successor provides an alternate path to reach the remote network without introducing loops.

The Reported Distance from a successor is lower than the local Feasible Distance: When a router receives advertisements from its neighbors, it compares the Reported Distance (advertised distance from the neighbor) to the local Feasible Distance (best path metric known so far). If the Reported Distance from a successor is lower than the local Feasible Distance, the router considers it as a feasible successor and maintains it as an alternate path.

QUESTION: 30

Which undesired effect of increasing the jitter compensation buffer is true?

The overall transport delay decreases and quality improves.
The overall transport jitter increases and quality issues can occur.
The overall transport delay increases and quality issues can occur.
The overall transport jitter decreases and quality improves.

Answer(s): C

Explanation:

Jitter compensation buffers are used to mitigate the effects of network jitter, which is the variation in packet arrival times. By increasing the size of the jitter compensation buffer, the system is able to store and hold incoming packets for a longer period, allowing for greater flexibility in handling variations in packet arrival times.

However, increasing the buffer size introduces additional delay in the system. Packets are held in the buffer for a longer duration before being forwarded, resulting in increased overall transport delay. This increased delay can lead to quality issues, especially in real-time applications such as voice or video, where timely delivery of packets is crucial.

Therefore, increasing the jitter compensation buffer may help in smoothing out variations in packet arrival times, but it can also introduce increased delay and potentially impact the quality of the transmitted data.

What the 400-007 Exam Covers

The 400-007 exam covers a comprehensive range of domains that are essential for any expert-level network designer, starting with Business Strategy Design, which requires candidates to understand how to align technical network requirements with the broader financial and operational goals of a business. This is followed by the Control, Data, Management Plane, and Operational Design domain, where candidates must demonstrate their ability to architect the underlying mechanisms that keep a network stable, manageable, and efficient. The Network Design domain serves as the core of the exam, testing the candidate's proficiency in creating scalable, resilient, and high-performance topologies that meet diverse organizational needs. Furthermore, the Service Design domain focuses on the delivery of specific network services, ensuring that the architecture supports the applications and user experiences required by the business. Finally, the Security Design domain integrates critical protection measures into the overall architecture, ensuring that the network remains resilient against threats while maintaining performance. Our practice questions are structured to reflect these domains, providing a balanced approach to your exam preparation by covering the theoretical and practical aspects of each area.

Among these domains, Business Strategy Design often presents the most significant challenge for candidates because it requires a shift in mindset from purely technical implementation to strategic decision-making. While many engineers are comfortable with the technical specifics of routing protocols or security features, they may struggle with the requirement to justify design choices based on business constraints, such as budget, time-to-market, and total cost of ownership. To succeed in this area, candidates must demonstrate a deep understanding of how different design choices impact the business's bottom line and operational agility. This requires the ability to analyze complex scenarios and determine which trade-offs are acceptable in a given context, a skill that is heavily tested through our practice questions. Mastering this domain is essential, as it separates those who can simply build a network from those who can design a network that truly serves the organization's strategic vision.
