In a Cisco Router What is the ip domain lookup command used for?
Enables DNS-based host name-to-address translation. This feature is enabled by default. So if you type something that appears to be a hostname the router will try to resolve it. This will happen three times, waiting for the dns request to time out. This can take a lot of time and when your trying to get things done could become annoying...

What are the three basic types of data?
Java has a total of 8 primitive data types
# byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). # short: The short data type is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive) # int: The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). # long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). # float: The float data type is a single-precision 32-bit IEEE 754 floating point. # double: The double data type is a double-precision 64-bit IEEE 754 floating point. # boolean: The boolean data type has only two possible values: true and false. # char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive). In addition to the eight primitive data types listed above, the Java programming language also provides special support for character strings via the java.lang.String class. Enclosing your character string within double quotes will automatically create a new String object;
For ex: String name = "Rocky"; would create a new String object of name "name" and holding an initial value "Rocky"
As of now Cisco is Worth much more than $200b [$600b-$200b]. This is most likely its minimum value due to the fact that they are finally digging into the international market.
A VLAN trunk allows for data to travel across a single link between two devices even if the data is from multiple VLANs. This allows for reduced cabling needed as for you won't have to run multiple cables between switches in order to have up-links for every VLAN.
What kinds problems are caused by excessive broadcasts traffic on a network segment?
Network capacity taken up by broadcasts cannot be used by normal network traffic, and because broadcast domains are not (by default) broken up by switches (only routers) they typically affect large numbers of hosts simultaneously.
Users will complain of slow or unavailable network response if it gets too bad.

This is where administrative distance comes into play. The lowest one gets used in the routing table. A static route always has a lower AD than dynamic routing processes. So the static route will be used.
Does a cisco router has a cmos battery?
Not so much a CMOS battery, but the data in NVRAM (startup-config) is in some models powered by a battery, which is pretty much the equivalent. In other models (among them the 2600 series) NVRAM is implemented with an EEPROM which does not use a battery.
