Questions 23-28 ·Read the magazine article below about a new tape storage system. ·For questions (23-28), choose the correct answer. ·Mark one letter (A, B or C) . TapeStore: A NEW TAPE STORAGE SYSTEM TapeStore is a new kind of tape storage system which can store up to 6,000 computer tapes. No other tape storage system can hold as many computer tapes as TapeStore. The tapes look exactly like video cassettes. Many hundreds of data files can be stored on each tape, up to a maximum of 500 million bytes of data. If you stored the same amount of information on paper, you would need nearly 4.5 billion printed pages. The machine is a tall black box with a mechanical arm. The machine is 2.5 metres high and 3 metres wide. This is how it works. Each tape has a code printed on it. You feed the code number into TapeStore, which then looks for the code. As soon as TapeStore locates the code, the arm reaches in and pulls out the tape. The system is very fast. It takes the mechanical arm about 10 seconds to find the tape it is looking for. The machine then searches the tape to extract the required file, and this take Less than a minute. A human technician would have to locate and remove the tape by hand,and could take at least an hour to find the right file on the tape. Some of the world’s biggest companies, including banks, insurance companies,airlines, telephone companies, utilities and computer centres, have bought the system.They like it particularly because the system guarantees the security of their data. TapeStore was originally developed in Canada and is now being marketed world-wide. In Europe alone, 750 have already been installed at a cost of 480,000 dollars each. According to the text, the main advantage of TapeStore over a human operator is that TapeStore
A.is more reliable.
B.is much faster.
C.is very secure.
某机构要新建一个网络,除内部办公、员工邮件等功能外,还要对外提供访问本机构网站(包括动态网页)、E-mail服务和FTP服务,设计师在设计网络安全策略时,给出的方案是:利用DMZ保护内网不受攻击,在DMZ和内网之间配一个内部防火墙,在DMZ和Internet间配置一个外部防火墙。内部网络使用地址段10.x.x.x/24进行IP地址规划设计。 为了使该机构的网站、E-mail和FTP服务能被在外出差的员工正常访问,需要进行的设置是______。 若WWW服务器提供SSL验证的某项服务,以保证外部访问者的口令等敏感信息以密文方式传输,则______。
A. 为这些内部服务器各配置两种IP地址:①是内部私有IP地址,②是公网IP地址
B. 直接为这些内部服务器各配置一个公网的IP地址
C. 在外部防火墙上设置对外合法的服务器IP地址到内部地址的对应关系,放行几条访问所需协议的安全规则
D. 在内部防火墙上设置对外合法的服务器IP地址到内部地址的对应关系,在外部防火墙上仅允许HTTP、FTP、SMTP、POP3等协议的数据包通过
