CCNAv2 Chapter 7 Quiz 7 and 7.1 Full Answers (100%)

Greetings, and welcome to Seeseenayy.
Here are the quizzes from chapter 7    (CCNA2), chapter 7 and 7.1 quizzes to be more exact.


This quiz covers the content in CCNA R&S Routing & Switching Essentials Chapter 7. It is designed to provide an additional opportunity to practice the skills and knowledge presented in the chapter and to prepare for the Chapter Exam. You will be allowed multiple  attempts and the grade does not appear in the gradebook.    
There are multiple task types that may be available in this quiz. Rather than having static graphics to view, some items may require you to open a PT activity and perform some investigation and configuration of devices before answering the question.
NOTE: There are some small differences in how the questions score and operate in the Quiz and how they score and operate in the Chapter Exam. Quizzes allow for partial credit scoring on all item types to foster learning. Points on quizzes can also be deducted for answering incorrectly. This does not occur with the Chapter Exam.
Chapter 7 Quiz - Part II - 7.0
