We hold these truths to be self-evident, that all men are created equal, that they are endowed by the Creator with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness. That to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed.
第1题:
假设有String a = "A"; char b ='A'; int c=65,下面选项中正确的是( )。
A.if(a == b) {System. out. print("Equal") }
B.if(c == b) {System. out. print("Equal") }
C.if(a == c) {System. out. print ("Equal") }
D.if(c = b) {System. out. print("Equal") }
第2题:
A.全局配置优先,所以最终结果是peer 1.1.1.2的timer值取keep alive 30 hold 90
B.Peer配置优先,所以最终结果是peer 1.1.1.2的timer值取keep alive 10 hold 30
C.Timer取最小值,所以最终结果是peer 1.1.1.2的timer值取keep alive 10 hold 30
D.缺省配置为timer keep alive 60 hold 180,故peer 1.1.1.2具有比缺省值更快的检测peer连接故障的速度
