CiscoM2C1 Chapitre 1 module 2, test pour s'entrainer... Il manque une question par rapport au test de fin de chapitre, celle dans laquelle il faut associer des bulles entre elles... Douglas published on October 06, 2016 Stacked 1/19 Which switch form factor should be used when large port density, fault tolerance, and low price are important factors? fixed-configuration switch modular switch rackable 1U switch stackable switch 2/19 An administrator purchases new Cisco switches that have a feature called StackPower. What is the purpose of this feature? It enables many switches to be physically stacked in an equipment rack. It enables many switches to be connected with a special fiber-optic power cable to provide higher bandwidth. It enables many switches to be connected to increase port density. It enables the sharing of power among multiple stackable switches. It enables AC power for a switch to be provided from a powered patch panel. 3/19 Refer to the exhibit. Fill in the blank.There are *** collision domains in the topology. Type answer. Hint: 2 characters 4/19 Refer to the exhibit. Fill in the blank.There are *** broadcast domains in the topology. Type answer. Hint: 1 character 5/19 Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty? SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch. SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch. SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch. SW1 drops the frame because it does not know the destination MAC address. 6/19 Refer to the exhibit. Consider that the main power has just been restored. PC1 asks the DHCP server for IPv4 addressing. The DHCP server sends it an IPv4 address. While PC2 is still booting up, PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request? to Fa0/1 only to Fa0/1 and Fa0/2 only to Fa0/1, Fa0/2, and Fa0/3 only to Fa0/1, Fa0/2, Fa0/3, and Fa0/4 to Fa0/1, Fa0/2, and Fa0/4 only 7/19 Which type of transmission does a switch use when the destination MAC address is not contained in the MAC address table? anycast broadcast multicast unicast 8/19 What is a collapsed core in a network design? a combination of the functionality of the access and distribution layers a combination of the functionality of the distribution and core layers a combination of the functionality of the access and core layers a combination of the functionality of the access, distribution, and core layers 9/19 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 source IP address and incoming port number destination IP address and incoming port number 10/19 What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.) Hint: 2 choices to create fewer collision domains to enhance user bandwidth to create more broadcast domains to eliminate virtual circuits to isolate traffic between segments to isolate ARP request messages from the rest of the network 11/19 Fill in the blank : A *** network is one that uses the same infrastructure to carry voice, data, and video signals. Type answer. Hint: 9 characters 12/19 What does the term “port density” represent for an Ethernet switch? the memory space that is allocated to each switch port the number of available ports the numbers of hosts that are connected to each switch port the speed of each port 13/19 What are two advantages of modular switches over fixed-configuration switches? (Choose two.) Hint: 2 choices lower cost per switch increased scalability lower forwarding rates need for fewer power outlets availability of multiple ports for bandwidth aggregation 14/19 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 15/19 What is one function of a Layer 2 switch? forwards data based on logical addressing duplicates the electrical signal of each frame to every port learns the port assigned to a host by examining the destination MAC address determines which interface is used to forward a frame based on the destination MAC address 16/19 What is a basic function of the Cisco Borderless Architecture access layer? aggregates Layer 2 broadcast domains aggregates Layer 3 routing boundaries provides access to the user provides high availability 17/19 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.) Hint: 2 choices lower bandwidth requirements reduced cost for equipment and user training easier to provide redundant links to ensure higher availability less required equipment to provide the same performance levels simpler deployment for additional switch equipment 18/19 What is a basic function of the Cisco Borderless Architecture distribution layer? aggregating all the campus blocks acting as a backbone aggregating Layer 3 routing boundaries providing access to the user 19/19 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? host hub switch NIC
