When a collision occurs on a shared Ethernet network, what is the first step in recovery for the two computers in question? Resend the last frame tight away. Send a jamming signal. Do nothing until the line clears. Wait for the other computer to finish. Which of the following is the most essential fact that allows the IEEE autonegotiation protocol to function? Cisco switch logic can determine speed and duplex for a connection. Cisco meets the IEEE standard for the protocol. Wiring pinouts are common for 10BASE-T, 100BASE-T, and 1000BASE-T. Any Ethernet device can sense the speed of a connection. What is the name used to identify a virtual NIC type of device that exists on Cisco switches to assign IP information to specific VLANs SVC SVI VRF PVC What Cisco 1OS command is used to create a VLAN and enter into VLAN configuration mode? vlan vlan primary vlan vlan interface vlan vlan vlan name What is the longest copper cable length supported by the IEEE 802.3u FastEthernet standard? 180 feet 1 kilometer 180 meters 100 meters 100 feet If a Cisco Gigabit Ethernet port is connected to a device that does not support iEEE autonegotiabor, and the interface speed cannot be sensed, what speed is the interface defaulted into? 1 Gbos 10 Mises 100 Moos None, the port is theit down What is the difference between the ISO version of HDLC and the Cisco version of HDLC that is used, by default, on all serial interfaces? Protocol field Type field Authentication support Optimized header Encryption support fiefer to the figure. From the output shown from the show interface status command, what can be determined about how ipeed and duplex were assgned to interface Foln? (Select all that apply.) Spoed was not auloriegotialed. Speed was autonegotiated Duplax was not autonogotiated Duplex vas astonegceiated You just unpacked a brand new Cisco 2960 switch. Which portsfinterfaces are ready to connect to and be used to set up the switch? fa0/1 VTY Console AUX Which of the following will disable autonegotiation for an interface on a Cisco switch? Setting both the speed and duplex settings for the interface Setting the duplex setting for the interface Autonegotiation is disabled by default Setting the speed setting for the interface Which are TRUE statements about STP PortFast mode? It starts the generation of STP TCN BPDU in port upidown conditions: If should be used on all swich uplink pots to speed convergence in case of a network fallure. The port bypasses the normal STP startup process and entore forwarding mode immediately. Special BPDUs are generated to notify the other switches that the port is an access port and any swiches connectod to it shoudd cause the port to be disable What is the only way an engineer can alter the value of the bridge ID? Modify the main switch MAC address Configure the STP priority Configure the bridge ID under STP configuration mode Swap out the main switch network interface card How many bits within the IEEE 802.1Q tag are used to identify the VLAN of the frame? 16 48 12 8 Which STP mode is the default on most modern Cisco Catalyst switches? RPVST+ PVST+ MST CST The IEEE 802.1Q standard adds a(n) -byte tag to the original frame to identify the VLAN. 1842
