Correct Answer: debug ip rip
Explanation:
The
debug ip rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router.
Correct Answer: 200.10.5.64
Explanation:
This is a pretty simple question. A /28 is 255.255.255.240, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
Correct Answer: Floods the network with the frame looking for the device
Explanation:
Switches flood all frames that have an unknown destination address. If a device answers the frame, the switch will update the MAC address table to reflect the location of the device.
Correct Answer: 2, 3 and 5
Explanation:
Hubs cannot run full-duplex Ethernet. Full duplex must be used on a point-to-point connection between two devices capable of running full duplex. Switches and hosts can run full duplex between each other, but a hub can never run full duplex.
Correct Answer: About 65-75 feet
Explanation:
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 65 to 75 feet.
Correct Answer: ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
Explanation:
The command
ip nat pool <name> creates the pool that hosts can use to get onto the global Internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224. Option C is wrong because the pool name has a lower case "T" in the pool name. Pool name's are case sensitive.
Correct Answer: 3, 4 and 5
Explanation:
Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the
no shutdown command.
Correct Answer: One access list may be configured, per direction, for each layer 3 protocol configured on an interface.
Explanation:
A Cisco router has rules regarding the placement of access lists on a router interface. You can place one access list per direction for each layer 3 protocol configured on an interface.
Correct Answer: Decrease the window size.
Explanation:
A receiving host can control the transmitter by using flow control (TCP uses Windowing by default). By decreasing the window size, the receiving host can slow down the transmitting host so the receiving host does not overflow its buffers.
Correct Answer: 3 and 4
Explanation:
Cisco has a proprietary trunking protocol called ISL. The IEEE version is 802.1Q.
