CCNA Switch Q 1 – Flashcards

Refer to the exhibit: Switch-1#show mac address-table Dynamic Address Count: 3 Secure Addresses (User-defined) Count: 0 Static Addresses (User-defined) Count: 0 System Self Addresses Count: 41 Total Mac Addresses: 50 Non-static Address Table: Destination Address Address Type VLAN Dest Port 0010.0de0.e289 Dynamic 1 Fa0/1 0010.7b00.1540 Dynamic 2 Fa0/3 0010.7b00.1545 Dynamic 2 Fa0/2 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? A. Switch-1 will drop the data because it does not have an entry for that MAC address. B. Switch-1 will forward the data to its default gateway. C. Switch-1 will flood the data out all of its ports except the port from which the data originated. D. Switch-1 will send an ARP request out all its ports except the port from which the data originated.

A technician has installed SwitchB and needs to configure it for remote access from the management workstation connected SwitchA. Which set of commands is required to accomplish this task? A. SwitchB(config)#interface FastEthernet 0/1 SwitchB(config)#ip address 192.168.8.252 255.255.255.0 SwitchB(config)#no shutdown B. SwitchB(config)#ip default-gateway 192.168.8.254 SwitchB(config)#interface vlan 1 SwitchB(config)#ip address 192.168.8.252 255.255.255.0 SwitchB(config)#no shutdown C. SwitchB(config)#interface vlan 1 SwitchB(config)#ip address 192.168.8.252 255.255.255.0 SwitchB(config)#ip default-gateway 192.168.8.254 255.255.255.0 SwitchB(config)#no shutdown D. SwitchB(config)#ip default-network 192.168.8.254 SwitchB(config)#interface vlan 1 SwitchB(config)#ip address 192.168.8.252 255.255.255.0 SwitchB(config)#no shutdown

A switch is configured with all ports assigned to vlan 2 with full duplex FastEthernet to segment existing departmental traffic. What is the effect of adding switch ports to a new VLAN on the switch? A. More collision domains will be created. B. IP address utilization will be more efficient. C. More bandwidth will be required than was needed previously. D. An additional broadcast domain will be created.

Which three statements accurately describe layer 2 Ethernet switches? (choose three) A. Microsegmentation decreases the number of collisions on the network. B. If a switch receives a frame for an unknown destination.it uses ARP to resolve the address. C. Spanning Tree Protocol allows switches to automatically share vlan information. D. In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port. E. Establishing vlans increases the number of broadcast domains. F. Switches that are configured with vlans make forwarding decisions based on both layer 2 and layer 3 address information.

Why will a switch never learn a broadcast address? A. Broadcast frames are never sent to switches. B. Broadcast addresses use an incorrect format for the switching table. C. A broadcast address will never be the source address of a frame. D. Broadcasts only use network layer addressing. E. A broadcast frame is never forwarded by a switch.
