Cisco CCNA 200-125 Certification Exam Answers 70 questions last 2018 Part 2

1. How do you maintain security in multiple websites?


2. Refer to the exhibit.

Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data?

Switch-1 will drop the data because it does not have an entry for that MAC address.
Switch-1 will flood the data out all of its ports except the port from which the data originated.*
Switch-1 will send an ARP request out all its ports except the port from which the data originated.
Switch-1 will forward the data to its default gateway.

3. What routing protocol use first-hand information from peers?



The reason is that unlike the routing-by-rumor approach of distance vector, link state routers have firsthand information from all their peer routers. Each router originates information about itself, its directly connected links, and the state of those links (hence the name). This information is passed around from router to router, each router making a copy of it, but never changing it. The ultimate objective is that every router has identical information about the internetwork, and each router will independently calculate its own best paths.
