A server contains a 3 disk RAID 5 array. The red LED is illuminated on one of the drives. Which of the following should the server administrator perform?()
Which three form part of correct array declarations?()
A new storage array must be configured for a database server. This array will store transaction logs that are always being written. Which of the following RAID solutions would provide fault tolerance and fast write operations without the use of parity?()
RAID(Redundant Array of Inexpensive Disks),是指将多个磁盘连成一个阵列,然后以某种方式写磁盘,Raid6这种方式可以在()磁盘失效的情况下防止数据丢失。
Which of the following is the correct configuration for a RAID 5 array?()
已知Var a:array[1..10] of integer;
执行后输出的是()
A new storage array must be configured for a database server. This array will store transaction logs that are always being written. Which of the following RAID solutions would provide fault tolerance and fast write operations without the use of parity?()
设有定义“doublearray[10];”,则表达式sizeof(array)/sizeof(array[0])的结果为array数组的()。
若有a=Array(1,2,3,4),a(2)的值是()。
有矩阵:VAR A:ARRAY[1‥100,1‥100] OF integer;元素按行存储。在一虚存系统中,采用LRU淘汰算法,一个进程有3页内存空间,每页可以存放200个整数。其中第1页存放程序,且假定程序已在内存。 程序A: FOR i:=1 TO 100 DO FOR j:=1 TO 100 DO A[i,j]:=0; 程序B: FOR j:=1 TO 100 DO FOR i:=1 TO 100 DO A[i,j]:=0; 分别就程序A和B的执行进程计算缺页次数。
