Correct Answer: DHCP
Explanation:
Dynamic Host Configuration Protocol (DHCP) is used to provide IP information to hosts on your network. DHCP can provide a lot of information, but the most common is IP address, subnet mask, default gateway, and DNS information.
Correct Answer: 157, 0x9D
Explanation:
To turn a binary number into decimal, you just have to add the values of each bit that is a 1. The values of 10011101 are 128, 16, 8, 4, and 1. 128 + 16 + 8 + 4 + 1 = 157.
Hexadecimal is a base-16 number system. The values of hexadecimal are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F-16 characters total, from which to create all the numbers you'll ever need. So, if 1001 in binary is 9, then the hexadecimal equivalent is 9. Since we then have 1101, which is 13 in binary, the hexadecimal answer is D and the complete hexadecimal answer is 0x9D.
Correct Answer: Non-broadcast multi-access
Explanation:
Frame Relay, by default, is a non-broadcast multi-access (NBMA) network, which means that broadcasts, such as RIP updates, will not be forwarded across the link by default.
Correct Answer: Physical layer
Explanation:
If you see that a serial interface and the protocol are both down, then you have a Physical layer problem. If you see
serial1 is up,
line protocol is down, then you are not receiving (Data Link) keepalives from the remote end.
Correct Answer: reload
Explanation:
To completely replace the running-config with the startup-config, you must reload the router. Note : You may have picked option C, which isn't a bad answer. Remember, though, it doesn't replace the configuration, it appends it.
Correct Answer: There is more than one show command that starts with the letters ru.
Explanation:
The
% ambiguous command error means that there is more then one possible command that starts with
ru. Use a question mark to find the correct command.
Correct Answer: show mac address-table
Explanation:
The command
show mac address-table displays the forward/filter table on the switch.
Correct Answer: About 150 feet
Explanation:
The IEEE 802.11b standard provides a maximum data rate of up to only 11Mbps, and you can be around 150 feet, maybe farther, depending on conditions.
Correct Answer: Broadcast storms will occur on the switched network.
Explanation:
If spanning tree is disabled on a switch and you have redundant links to another switch, broadcast storms will occur, among other possible problems.
Correct Answer: show ip nat translations
Explanation:
The command
show ip nat translations will show you the translation table containing all the active NAT entries.
