Collision prevention on a LAN segment.
The sequence number in the TCP header
The Start Frame Delimiter in the 802.3 Preamble
The TTL in the IP header
The acknowledgement number in the segment header
The frame check sequence in the Ethernet frame trailer
Change from one transport layer protocol to another transport layer protocol.
Change to a better link for better connection.
Decrease the window size.
Receiver will flush the buffer to accommodate more data received.
Decrease the sequence number.
All the devices in both networks will receive a broadcast to 255.255.255.255 sent by host CompA.
Only the devices in network 192.168.1.0 will receive a broadcast to 255.255.255.255 sent by host CompA.
All the devices on both networks are members of the same collision domain.
The hosts on the 192.168.1.0 network form one collision domain, and the hosts on the 192.168.2.0 network from a second collision domain.
Each host is in a separate collision domain
Subnet mask error; 255.255.255.192 should be used instead.
Subnet mask error; 255.255.255.224 should be used instead.
Wrong cable type; a roll-over cable should be used instead.
Missing default gateway.
Should use private IP address instead.
Collision is cleared, hence the “jam” signal.
Request for retransmission is sent from the receiver.
Another electrical signal would be generated to inform that it is clear.
Both hosts would ignore the “jam” signal.
A time delay would be initiated by both hosts and will resume sending after.
Make copy of the frame and send the frame back through the receiving port.
Drop the frame.
Forwards the frame to all active ports except the receiving port.
Remove the MAC address recorded.
Forwards the frame to the specific port.
Two end hosts send the same data to a third host in the same physical switch.
Two end hosts connected physically on two ports but on the same VLAN in the same switch.
The port connecting to a host just replaced the NIC.
Two hosts connect physically to a hub that connects to the Fast Ethernet port of the switch.
It is not possible for this to occur.
VTP allows creation of redundant physical links while preventing loops.
VTP allows easier management through automatic updates on VLAN information.
VTP allows passing of multiple VLAN traffic through one single physical interface.
VTP allows the possibility of inter-VLAN routing.
None of the above.
The switch that will share the VLAN information must be the root bridge.
The new switch must be in the same VTP domain.
The new switch must have the same STP version.
The new switch must have the same VTP version.
The new switch must be connected over VLAN trunks.
VLANs allows packet filtering and thus enhancing security.
VLANs establish segmented broadcast domains in switched networks.
VLANs allow hosts to communicate using IP addresses in a large network.
VLAN allows grouping based on network service requirement.
VLANs is very scalable in any organization.
Configure switch to do packet filtering to permit only packets from the file server.
Configure a static file server’s MAC address entry on the selected port.
Use a unique connector to allow only that host to connect.
Configure on selected port to reject all frames except frames matching MAC address of file server.
Bind IP address of the server to the port to prevent spoofing of packets.
Host P and Host Q
Host P and Host R
Host Q and Host R
Host Q and Host S
Host P and Host S
Allowing only recognized hosts using recorded MAC to access the LAN.
Reduce broadcast traffic from being sent out from the configured port.
Preventing unauthorized telnet and/or SSH sessions coming in/going out the port.
Allowing only recognized packets using recorded IP addresses to access the LAN.
To ensure the host is connecting to the correct VLAN based on the recorded MAC.
The broadcast address of the subnet is 172.30.31.255 255.255.252.0.
This network is not subnetted.
The last valid host address in the subnet is 172.30.30.254 255.255.252.0
The network address is 172.30.30.0 255.255.252.0.
The last host address in the subnet is 172.30.31.254 255.255.252.0.
RouterA will route via Serial0/0/0 interface.
RouterA will flood to all other interfaces except the receiving interface.
RouterA will drop the packet because it is clearly not in the routing table.
RouterA will route via FastEthernet0/0 interface.
RotuerA will route via Serial0/0/1 interface.
