What does the term DYNAMIC indicate in the output that is shown? This entry can only be removed from the MAC address table by a network administrator. SW1 encapsulates the traffic with 802. configure a second switch as a VTP server to take over in case of a primary VTP server failure. 48. SW1 leaves the traffic untagged and forwards it over the trunk. Refer to the exhibit.1Q encapsulation and forwards it over the trunk link. 49. . the switch does not have to perform a lookup to determine the final destination port.47. Refer to the exhibit. How does SW1 manage traffic coming from Host A? SW1 drops the traffic because it is untagged. What should be done in the future to prevent losing all VLAN configurations in a VTP domain? Configure all switches in VTP transparent mode and copy the VLAN configuration into flash. The VTP domain has been configured as shown in the exhibit. SW1 tags the traffic with the lowest VLAN ID value and forwards it over the trunk link. After the technician reloaded the switches. Only the device with MAC address 0060.5c5b.

Refer to the exhibit.

51. No routing protocol is configured on Router1. The PC has a ping success rate to the default gateway of less than half the ping attempts. What is the most likely cause of this problem? Switch port Fa0/1 is not trunking. Other PCs on the switch can consistently ping the default gateway. which causes a duplex mismatch. What will commonly cause this problem? The PC is set to full duplex. A network administrator has segmented the network into two VLANs and configured Router1 for inter-VLAN routing. The default gateway is not on the same switch that the PC is. The result is that frames are being dropped. One of the router subinterfaces is possibly down. A test of the network. 52.50. The switch traffic is exceeding available frame buffers. however. What impact does the use of the mdix auto configuration command have on an Ethernet interface on a switch? automatically detects duplex settings automatically detects interface speed automatically detects copper cable type automatically assigns the first detected MAC address to an interface ————-New questions update 2011—————————– 53 . shows that hosts on each VLAN can only access local resources and not resources on the other VLAN. The switch port is configured for auto duplex and the PC is configured for full duplex. The switch port fails to autonegotiate the duplex setting and defaults to half duplex. Router interface Fa0/0 is possibly down. An administrator is troubleshooting a PC on the network which is suffering from slow and intermittent connectivity. Refer to the exhibit.

How do the hosts respond on the network? (Choose two. All hosts are in listen mode. • Hosts 1 and 4 are operating full duplex so no collision will exist. 56. Refer to the exhibit. What action will the switch take when it receives the frame shown at the bottom of the exhibit? • discard the frame • forward the frame out port 2 . • Hosts 1 and 4 are assigned shorter backoff values to provide them priority to access the media.Refer to the exhibit. • The hub will block the port connected to Host 4 to prevent a collision. An administrator documented the output of a CAM table from an Ethernet switch as shown.) • After the end of the jam signal. • If a host has data to transmit after the backoff period of that host. a backoff algorithm is invoked. Host 1 and Host 4 both transmit data at the same time. the host checks to determine if the line is idle before transmitting.

. but the command history buffer is still available. What are valid considerations for reliability and administration? • Using server mode on a single master switch and client mode on all other switches will provide the most fault tolerance for retaining VLAN information in all switches if power is lost on the network. • The configuration file named tokyo-config will overwrite the startup configuration file on S1. A network administrator is implementing VTP in a large campus LAN that contains one hundred switches. • Configuring several switches in server mode will allow all VLANs to be entered from a single switch and preserve VLAN data if any of the switches or connections are lost. 59. • The Cisco IOS version does not support disabling the command history buffer. What is the problem? • The command contained a syntax error. • forward the frame out port 3 • forward the frame out all ports • forward the frame out all ports except port 3 • add station 00-00-3D-1F-11-05 to port 2 in the forwarding table 57. An administrator enters terminal no history size at the command prompt on a Cisco Catalyst switch and receives no error messages back. • The command history can only be disabled on a router. • The size parameter reset the default buffer size but did not disable access to the buffer. • The contents of NVRAM on S1 will become the startup configuration file on the tokyo switch. not a switch.16.155/tokyo- config? • The IOS will be copied to the TFTP server.2. • Using transparent mode on all switches will allow for efficient administration and prevent VLAN data loss from the loss of any single switch. What will be the effect of the command S1# copy system:running-config tftp://172. 58. • The running configuration file on S1 will be saved via TFTP to a file named tokyo-config. Company policy requires disabling the command history buffer on network devices.

What two pieces of information are indicated from the exhibited output? (Choose two. • Configuring one primary and one backup switch in server mode and all other switches in transparent mode will provide fault tolerance for the VLAN data and allow for efficient distribution of the VLAN configurations to all switches. Switch SW-A is to be used as a temporary replacement for another switch in the VTP Student domain. • VTP will block frame forwarding on at least one redundant trunk port that is configured on this switch. Refer to the exhibit. • There is a risk that the switch may cause incorrect VLAN information to be sent through the domain. 60. • This switch will update its VLAN configuration when VLAN changes are made on a VTP server in the same domain. 61.) • The other switches in the domain can be running either VTP version 1 or 2. What is the purpose of issuing the command switchport mode access on a switch interface? • disable port security • make the port operational • override the default port behavior • force the port to be a part of a single vlan . • VLAN configuration changes made on this switch will be sent to other devices in the VTP domain.

What happens when a frame from a source MAC address different from 00a8. • Client requests for DHCP addresses will be filtered out if the requests are not received on interface Fa0/2. • Only 100 clients are permitted to request DHCP addresses on VLAN 2. 64. • BPDUs may be discarded because of expiring timers. Refer to the exhibit. • An error message is displayed. • The port is shut down. Refer to the exhibit. • FastEthernet port 0/5 will show an err-disabled messag 63.d2e4.62. • DHCP server responses will only be permitted on interface Fa0/2. . Why is it important that the network administrator consider the spanning-tree network diameter when choosing the root bridge? • The network diameter limitation is 9.ba27 reaches switch port 0/5? • The frame is dropped. What will be the result of the commands that are shown in the exhibit? • Only clients on VLAN 2 will be able to use DHCP for addressing.
