CCNA 2 Exam 1 1 What is one advantage of using the cut-through switching method instead of the store-and-forward switching method? has a positive impact on bandwidth by dropping most of the invalid frames makes a fast forwarding decision based on the source MAC address of the frame has a lower latency appropriate for high-performance computing applications* provides the flexibility to support any mix of Ethernet speeds 2 A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.) reduced cost for equipment and user training less required equipment to provide the same performance levels simpler deployment for additional switch equipment* easier to provide redundant links to ensure higher availability* lower bandwidth requirements 3 What are two advantages of modular switches over fixed-configuration switches? (Choose two.) availability of multiple ports for bandwidth aggregation lower forwarding rates need for fewer power outlets* lower cost per switch increased scalability* 4 What is one function of a Layer 2 switch? forwards data based on logical addressing

learns the port assigned to a host by examining the destination MAC address duplicates the electrical signal of each frame to every port determines which interface is used to forward a frame based on the destination MAC address* 5 What is a collapsed core in a network design? a combination of the functionality of the access, distribution, and core layers a combination of the functionality of the access and core layers a combination of the functionality of the distribution and core layers* a combination of the functionality of the access and distribution layers 6 What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.) to enhance user bandwidth* to eliminate virtual circuits to create more broadcast domains to isolate traffic between segments* to isolate ARP request messages from the rest of the network to create fewer collision domains 7 What is a basic function of the Cisco Borderless Architecture distribution layer? aggregating Layer 3 routing boundaries* aggregating all the campus blocks acting as a backbone providing access to the user

8 ABC, Inc. has about fifty hosts in one LAN. The administrator would like to increase the throughput of that LAN. Which device will increase the number of collision domains and thereby increase the throughput of the LAN? hub host NIC switch* 9 What information is added to the switch table from incoming frames? source MAC address and incoming port number* destination MAC address and incoming port number destination IP address and incoming port number source IP address and incoming port number 10 Fill in the blank.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
