1) Compare and contrast the advantages and use cases for when you would use end-to-end VLANs versus local VLANs.Post Requirements: Your posts must use at least two (2) sources of information (properly cited using the American Psychological Association (APA) citation guidelines) in addition to the “hypermedia” already provided to you as part of the course. Your post must consist of a minimum of 250 words and a maximum of 500 words. Technical accuracy, proper in-text citations, and depth of coverage all play a critical role in your overall score.2) A concept that can cause a certain amount of confusion is that of the Native VLAN. By default, Cisco uses VLAN 1 as the Native VLAN. Your goal in this post is to describe why Cisco needs a native VLAN, what are the uses of the native VLAN on Cisco switches, and why Cisco actually recommends that you disable/shut down the native VLAN, VLAN 1.Post Requirements: Your posts must use at least two (2) sources of information (properly cited using the American Psychological Association (APA) citation guidelines) in addition to the “hypermedia” already provided to you as part of the course.

In this post you will have your 2nd opportunity to “Convince Me Otherwise!”Here is the statement you will tackle for this post: It makes no difference which version of VTP you use because there are no advantages of using one version over the other – they all function the same. Cisco only created three (3) versions to force you to upgrade your IOS software.

These bundles of ports can increase the available bandwidth, add redundancy, and make your network environment more resilient to individual port and/or line card failures. However, there are also significant configuration and operational considerations as to which port aggregation method is the most appropriate. Your task for this post is to compare and contrast the features, limitations, functionality, and use cases of each of the three (3) port aggregation approaches.Post Requirements: Your posts must use at least two (2) sources of information (properly cited using the American Psychological Association (APA) citation guidelines) in addition to the “hypermedia” already provided to you as part of the course.
