If you wanted to deny FTP access from network 200.200.10.0 to network 200.199.11.0 but allow everything else, which of the following command strings is valid?

	A.	access-list 110 deny 200.200.10.0 to network 200.199.11.0 eq ftp access-list 111 permit ip any 0.0.0.0 255.255.255.255
	B.	access-list 1 deny ftp 200.200.10.0 200.199.11.0 any any
	C.	access-list 100 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp
	D.	access-list 198 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp access-list 198 permit ip any 0.0.0.0 255.255.255.255

Your Answer: Option

Correct Answer: Option D

Explanation:

Extended IP access lists use numbers 100-199 and 2000-2699 and filter based on source and destination IP address, protocol number, and port number. The last option is correct because of the second line that specifies permit ip any any. (I used 0.0.0.0 255.255.255.255, which is the same as the any option.) The third option does not have this, so it would deny access but not allow everything else.

Which one of these lists contains only Java programming language keywords?

	A.	class, if, void, long, Int, continue
	B.	goto, instanceof, native, finally, default, throws
	C.	try, virtual, throw, final, volatile, transient
	D.	strictfp, constant, super, implements, do
	E.	byte, break, assert, switch, include

Your Answer: Option

Correct Answer: Option B

Explanation:

All the words in option B are among the 49 Java keywords. Although goto reserved as a keyword in Java, goto is not used and has no function.

Option A is wrong because the keyword for the primitive int starts with a lowercase i.

Option C is wrong because "virtual" is a keyword in C++, but not Java.

Option D is wrong because "constant" is not a keyword. Constants in Java are marked static and final.

Option E is wrong because "include" is a keyword in C, but not in Java.

Which of the following is true when describing a unicast address?
