QOS - Implementing Cisco Quality of Service v2.3

Cisco Course v2.3

GK# 5643

Course Overview


In this course, you will gain in-depth knowledge of Quality of Service (QoS) requirements, conceptual models such as Best-Effort, Integrated Services (IntServ), and Differentiated Services (DiffServ), and implementing QoS on Cisco IOS platforms. You will learn about the theory of QoS, design issues, and configuring various QoS mechanisms to facilitate the creation of effective QoS administrative policies.

Case studies and lab activities included in the course will help you apply the concepts you'll master to real-life scenarios.

In this course, you will learn design and usage rules for various advanced QoS features and for integrating QoS with underlying Layer 2 QoS mechanisms, enabling you to optimize multiservice networks.

For self-paced learning, you will have access to this course for 12 months from the purchase date.

Supplemental Assets:

Mentoring: Mentors are available to help you with your studies for the certification exams. You can reach them by entering a Mentored Chat Room or by using the Email My Mentor service.

Lab Simulations: Task-based multipath scenarios provide realistic practice of technology subjects or applications.

Class Notes/Study Guides: Printable study guide and class notes are intended to support your transfer of knowledge and skills from courses to the workplace. Use these to follow along with instruction, review prior to certification exams, or to reference on the job.

Pre- and Post-Courseware Assessments: Section-based assessments offer a range of practice and testing options within the section, including feedback and tracking.

Test Prep Exams: Practice tests will help you prepare for a certification exam. You can take a test prep exam in Study Mode (where you receive feedback after each question) or in Certification Mode (designed to mimic a certification exam) as many times as you want.
