                                          NEW QUESTION # 337
                                          Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

                                          Answer: D,E


                                          NEW QUESTION # 338
                                          Refer to the exhibit. An architect is designing a BGP solution to connect a remote branch to a service provider. There are several prefixes within the branch that the company does not want to be advertised to the internet. Which solution should the architect use to accomplish this?

                                          Answer: B


                                          NEW QUESTION # 339
                                          Which two statements describe source trees in a multicast environment? (Choose two.)

                                          Answer: D,E

                                          Explanation:
                                          In multicast routing, a source tree is also called a shortest-path tree because it is rooted at the multicast source and follows the best unicast path from receivers back toward that source. Cisco PIM documentation describes source trees as shortest-path trees and contrasts them with shared trees, which are rooted at a rendezvous point. Because the tree is built directly toward the source, it provides an optimal forwarding path between source and receivers and generally gives the lowest latency path for multicast delivery. This is why statements A and B are correct. A shared tree, not a source tree, uses a single common root at a selected point in the network, normally the RP in PIM sparse mode. Shared trees can create suboptimal forwarding because traffic may travel through the RP before switching to the shortest-path tree. Source trees require per-source multicast state, so they may consume more control-plane resources, but they are the correct choice when optimal forwarding and minimum latency are the design priorities.

The engineer plans to use an Internet connection but company policy requires the connection to be encrypted. Additionally, there are several applications that utilize multicast to deliver video streams between the sites. Which technology should the design include?

                                          Answer: D

                                          Explanation:
