第1题:

在网络管理协议SNMP中,可以对MIB数据有多种访问方式,分别针对不同的MIB数据用不同的方式,对于只读的MIB数据可以使用(1)获得MIB对象的值。关于描述mib对象sysDescr 只能使用(2)命令操作。

(1)A. GET和SET

B. GET和TRAP

C. TRAP和SET

D. GET

(2)A. 只读方式(Read-only)

B. 可读可写(Read-write)

C. 禁止访问(Not-accessible)

D. 随机访问(Random -Access)


正确答案:B,A
SNMP协议有如下的MIB数据对象访问方式: 
只读方式(Read-only)、可读可写(Read-write)、禁止访问(Not-accessible)。网络管理系统无法改动只读方式的MIB数据对象,但可以通过Get或Trap命令读取数据对象的值。在一件产品的使用期内,某些MIB的信息从不会改变。例如,MIB数据对象sysDescr,它代表System Description,包含了管理代理软件所需要的厂商信息。确定某些数据对象为只读还有另一个原因,即确保有关性能的信息及其它统计数据正确,不至于因误操作而改动它们。SNMP作为数据传输方法,和数据的组织形式MIB结合,为网络管理系统提供了底层的保障。
