More questions
Correct Answer: sh version
Explanation:
The best answer is
show version, which shows you the IOS file running currently on your router. The
show flash command shows you the contents of flash memory, not which file is running.
Correct Answer: /30
Explanation:
A point-to-point link uses only two hosts. A /30, or 255.255.255.252, mask provides two hosts per subnet.
Correct Answer: 172.16.64.0
Explanation:
A /21 is 255.255.248.0, which means we have a block size of 8 in the third octet, so we just count by 8 until we reach 66. The subnet in this question is 64.0. The next subnet is 72.0, so the broadcast address of the 64 subnet is 71.255.
Correct Answer: 2 and 4
Explanation:
The wildcard 0.0.0.0 tells the router to match all four octets. This wildcard format alone can be replaced with the
host command.
Correct Answer: Transport
Explanation:
The Transport layer receives large data streams from the upper layers and breaks these up into smaller pieces called segments.
Correct Answer: No IP traffic will be allowed out E0.
Explanation:
If you add an access list to an interface and you do not have at least one
permit statement, then you will effectively shut down the interface because of the implicit
deny any at the end of every list.
Correct Answer: About 300 feet
Explanation:
The IEEE 802.11g standard's lowest data rate is 6Mbps, but it can run from a distance of about 300 feet.
Correct Answer: STP
Explanation:
The Spanning Tree Protocol is used to stop switching loops in a switched network with redundant paths.
Correct Answer: 54Mbps
Explanation:
The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps.
Correct Answer: show interfaces
Explanation:
The command
show ip protocols will actually show you the broadcast address for each interface - too bad it isn't a possible answer. Your best answer is
show interfaces, which will provide the IP address and mask for each interface.
