The heat generated by the operating system war between rivals IBM Corp. and Microsoft Corp. is(21).Windows 95 and OS/2 introduce a new(22). Both systems claim to multitask legacy DOS and 16-bit Windows applications. However, only OS/2 can provide full memory(crash) protection for these legacy applications because it is capable of running each DOS and Windows application within its full-protected memory address space.Windows 95 will run all current Windows applications in the same shared- memory address space, affording full memory protection only to the(23)32-bit Windows 95 applications. In other word, Windows 95 users will have to(24)their current Windows applications to Windows 95 version to match the memory protection OS/2 now delivers.While OS/2 does afford superior memory protection and multitasking for legacy DOS and Windows applications, it will not be able to run any Windows 95 applications. IBM may address this(25)in an update of the OS but has no present plans to do so.
A．intensify
B．intensified
C．intensifying
D．intensifies

With Cisco NX-OS on a Cisco Nexus platform， which command shows memory usage， total processes， and CPU state？（）
第3题：
A. You cannot specify MEMORY_TARGET if you explicitly specify SGA_TARGET or PGA_AGGREGATE_TARGET values that are greater than zero in your parameter file.
B. Oracle can reallocate memory between the SGA and PGA automatically as needed.
C. To use Automatic Memory Management, you must explicitly set both the MEMORY_TARGET and MEMORY_MAX_TARGET parameters in your parameter file.
D. You can set the MEMORY_TARGET parameter to a maximum value of the current SGA size plus the current PGA size.

We know a computer is a machine that processes data(stored in main memory)into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instruictions must be stored in binary form. Characters are represented in(71). Numbers are stored as binary numbers, with each bit's positional value significant. A computer's main memory is divided into bytes, words or both(depending on the system), and each of these basic storage units is assigned an(72). Using this address, the processor can read or write selected bytes or words.
The processor consists of a clock, an instruction control unit, an arithmetic and logic unit, and registers. Once a program is stored in main memory, the processor can begin to execute it. During(73), the instruction control unit fetches an instruction from main memory; during(74), the arithmetic and logic unit executes it. Precisely timed electronic pulses generated by the clock drive this basic(75)
A．a binary code
B．words
C．registers
D．positional values

You issue the command show process memory ∣ include BGP and notice that BGP is consuming alarge percentage of the router’s memory. Which of the following steps would result in lowering theamount of memory being consumed by BGP？（Choose all that apply.）（）
第8题：
A. MEMORY_TARGET can be increased up to the value of MEMORY_MAX_TARGET, if MEMORY_MAX_TARGET is set to a value greater than zero
B. MEMORY_MAX_TARGET defaults to a value of zero if MEMORY_TARGET is not set
C. MEMORY_TARGET represents the total amount of memory that can be allocated to SGA and PGA memory structures.
D. MEMORY_TARGET is static and cannot be modified without shutting down the instance
第9题：
An administrator is adding additional memory into a server that registers 1GB of memory in the OS and notices that the system has 2GB of memory physically installed； however， the server only shows 1GB of memory during POST. Which of the following is the MOST likely reason for this？（）
