NETW204 Week 1 Quiz – DeVry University

NETW204 Week 1 Quiz – DeVry University | (TCO 1) What is the key function of the Cisco Borderless Architecture core layer? Acts as a bride between access and distribution layers You Answered Establishes layer 3 routing boundaries Aggregates layer 2 data to access layer Correct Answer Facilitates fault isolation and high-speed backbone connectivity Provides access to a secure data channel See Chapter 1. Question 2 1 / 1 pts (TCO 1) You are required to justify the need to implement a collapsed core network. Which justification below makes sense for a collapsed core network? Other options are too expensive Correct! Cost-effective solution for a smaller environment Ability to embed the functionalities of access and distribution into a single layer Makes sense to implement in large-scale enterprise networks to be more adaptable Ability to effectively implement security policies to meet business needs This study source was downloaded by from CourseH on :00:50 GMT -05:00 See Chapter 1. Question 3 1 / 1 pts (TCO 1) Name one advantage of modular switches over fixed-configuration switches. Correct! Easier management of switched network Increased throughput Fewer data drops Easier to remove port aggregation Increased delay See Chapter 1. Question 4 1 / 1 pts (TCO 1) Name one advantage of fixed-configuration switches over modular switches. Need fewer power outlets Increased security on backplane Better scalability Increased overall layer 2 performance Correct! None of the above See Chapter 1.

Minimize delay Always increased overall network throughput None of the above See Chapter 1. Question 6 1 / 1 pts (TCO 1) A switch receives a frame from Server-1 with destination to Host-A. Both devices’ Physical addresses are registered in the Switch MAC Address Table. Where does the switch send the frame? Forward the frame as a broadcast to all egress ports except for the ingress port Avoid a layer two loop by sending the frame to the main backplane of the switch Correct! Directly from Server-1 to Host-A A and C None of the above See Chapter 1.
