Refer to the exhibit. A packet is received on the FastEthernet 0/1 physical interface from VLAN 1. The packet destination address is 192.168.1.85. What will the router do with this packet?
The router will ignore the packet because the source and destination are on the same broadcast domain.
The router will forward the packet out interface FastEthernet 0/1.1.
The router will forward the packet out interface FastEthernet 0/1.2.
The router will forward the packet out interface FastEthernet 0/1.3.
The router will drop the packet since no network that includes the source address is attached to the router.
Refer to the exhibit. All the VLANs configured on S2 are present on S1 but not S3. All switches are set to VTP server mode and have identical VTP domain names configured. What is the likely problem?
The connection from S1 to S3 is not trunking.
S3 does not have a management VLAN configured.
The VLAN 99 interface on S3 is in a different subnet than S1 and S2.
S3 was joined to the network with a lower revision number than S1.
Refer to the exhibit. Switches C1, D1, D2, and S2 have all been configured with RSTP. S1 and S3 are not capable of rapid PVST+ and are in the default configuration. What three implications does this have for the Layer 2 network? (Choose three.)
Because S1 and S3 are not trunking, they have no spanning-tree instance.
A topology change BPDU from C1 forces the uplinks on S1 and S3 to stop forwarding traffic for twice the forward delay time.
Port Gi0/1 on D1 and port Gi0/1 on D2 become designated ports.
Loss of the root port link on S2 causes a rapid transition to non-designated port on S2.
PortFast can be enabled on all ports on S1 and S3.
Gi0/1 on S1 and Gi0/1 on S3 become designated ports.
Refer to the exhibit. The network administrator enters the configuration shown to allow both SSH and Telnet connections to the switch. The Telnet connections fail. What is the most likely cause of this problem?

Telnet and SSH cannot be configured simultaneously.
Refer to the exhibit. Spanning-tree port priorities are listed beneath each interface. The network administrator enters the spanning-tree vlan 1 root primary command on S4. Which three port results are correct? (Choose three.)
Refer to the exhibit. Three new VLANs have been configured to improve the performance of the network. Host A would like to send a frame destined to Host B. Which statement is true about the process of sending the frame?
Host A sends an ARP request to the default gateway configured for VLAN10 to resolve destination MAC to IP address mapping. Then the frame is sent to switch SW1 only to switch the traffic to Host B.
Host A sends an ARP request to the default gateway for VLAN10 to resolve destination MAC to IP address mapping. Then the frame is sent to router R1 to route the traffic to the appropriate VLAN.
Host A broadcasts an ARP request to the members of all VLANs. If none of the hosts replies with a corresponding IP address, the frame is dropped.
Because Host A and Host B are connected to the same switch SW1, Host A forwards the frame to Host B directly.
Refer to the exhibit. Switch SW2 was tested in a lab environment and then inserted into a production network without reloading its configuration. After the trunk link between SW1 and SW2 was brought up, all users lost connectivity to the network. What could be the source of the problem?
The newly inserted switch has a higher VTP server revision number, which caused the VLAN information in the VTP domain to be deleted.
The newly inserted switch has pruning enabled, which causes pruning of all VLANs from the trunk port.
The newly inserted switch received more VLANs from a connected switch than the switch can support.
Switches can exchange VTP information only through an access link.
Refer to the exhibit. Hosts PC_A and PC_B send traffic simultaneously, and the frames from the transmitting stations collide. How far is the collision propagated?

If the link between D1 and C1 fails, port Gi0/2 on S2 rapidly transitions to the forwarding state.
PortFast is enabled on Gi0/2 on S2.
Port Gi0/2 on S2 becomes a designated port.
Broadcast packets are restricted on the link between S2 and D1.

S1 port fa0/11 is in the wrong VLAN.
Pc1 IP address is incorrect.
R1 does not have an active routing protocol.
Router interface fa0/0 has the wrong trunk encapsulation type configured.
Refer to the exhibit. After the listed commands are entered into router R1 and switch S1, the administrator enters the show interface fa0/1 trunk and gets the results shown. What is the likely problem?
The trunk is established, but no VLANs have been configured to use it.
The trunk has not been established because the router does not support dynamic trunking protocol.
The router, the switch, or both must be configured with the dynamic desirable option for dynamic trunking protocol to establish a trunk.
The router is missing the dynamic trunking protocol statements necessary to form a trunk.
Refer to the exhibit. Two switches, SW1 and SW2, are interconnected via a trunk link. Host A is on the native VLAN. How does untagged traffic coming from Host A traverse the trunk link?
SW1 tags the traffic with the lowest VLAN ID value and forwards it over the trunk link.
SW1 tags the traffic with the highest VLAN ID value and forwards it over the trunk link.
The untagged traffic is forwarded as part of the native VLAN.
The untagged traffic is dropped because the trunk forwards only tagged frames.
SW1 encapsulates the traffic with 802.1p encapsulation and forwards it over the trunk link.
SW1 encapsulates the traffic with 802.1Q encapsulation and forwards it over the trunk link.
Refer to the exhibit. The Fast Ethernet port Fa0/1 on the switch is configured for auto-negotiate speed/duplex settings, and the NIC on the machine is set to 100 Mbps, full-duplex. The log error message shown has been received. What two solutions could fix the problem? (Choose two.)

Refer to the exhibit. On the basis of the configuration shown, how will an Ethernet frame on port GigabitEthernet0/1 be modified?
802.1Q encapsulation prepends a 4-byte tag field in front of the original Ethernet frame and recomputes the frame check sequence (FCS) on the modified frame.
802.1Q encapsulation inserts a 4-byte tag field into the original Ethernet frame between the source address and type or length fields.
802.1Q encapsulation prepends an 802.1p field in front of the original Ethernet frame and recomputes the frame check sequence (FCS) on the modified frame.
802.1Q encapsulation inserts an 802.1p field into the original Ethernet frame between the source address and type or length fields.
Refer to the exhibit. A host attached to port Fa0/3 of the switch can communicate with the host connected to port Fa0/16, but cannot communicate with the host connected to port Fa0/2. What could account for this failure?
Fa0/3 is down.
The trunk link to the router is down.
The VLAN0010 network address is missing from the routing table.
Fa0/2 has been assigned to the administrative VLAN.
The router does not have a functional routing protocol installed.
A network administrator wants to add a new switch to the existing VTP domain. The new switch will have a VLAN that the administrator does not want visible to any other switches. All other VLANs should be visible on all switches, and all VLANs should be visible to the new switch. Which solution meets the requirements with the least administrative effort?
Add the switch in server mode. After all VLANs have propagated to the new switch, change the trunked link to access mode. Add the private VLAN to the new switch.
Add the switch in server mode. Add an extended range VLAN to the new switch as the private VLAN.
Add the switch in server mode. Add the private VLAN to the new switch. Enable VTP pruning and ensure that no ports are placed in the private VLAN on any other switches.
Add the switch in client mode. After the existing VLANs have propagated, change the switch to transparent mode. Add the private VLAN.
Add the switch in VTP transparent mode. Manually add all VLANs to the switch.
Refer to the exhibit. Each switch is shown with its MAC address. Which switch will be elected as the spanning-tree root bridge if the switches are configured with their default priority values?
Refer to the exhibit. All hosts are in listen mode. Host 1 and Host 4 both transmit data at the same time. How do the hosts respond on the network? (Choose two.)
Hosts 1 and 4 may be operating full duplex so no collision will exist.
The hub will block the port connected to Host 4 to prevent a collision.
After the end of the jam signal, a backoff algorithm is invoked.
Hosts 1 and 4 are assigned shorter backoff values to provide them priority to access the media.
If a host has data to transmit after the backoff period of that host, the host checks to determine if the line is idle, before transmitting.

An access point supports both the 802.11g and 802.11b standards. A device that supports only 802.11b attempts to connect to the access point. What happens to the connection?
The network does not connect unless the user is within line of sight of the access point.
The access point and all other connected users defer to the 802.11b standard.
The access point always maintains the higher standard and automatically upgrades the 802.11b device to the 802.11g speed.
Each user gets the speed supported by the wireless NIC on their mobile device.
