As groupware applications that use servers on the corporate network connected via
WAN, two systems are developed; one is a product catalog system, which requires
regular updates of large volumes of data including graphic information, and the other is
a conference room reservation system, which requires real-time data update. The

databases between servers, and allow updated data from a source database to be
reflected on a destination database at a specified time. From viewpoints of the data
volume and application operations, which of the following is an appropriate
deployment of the databases?

a) The product catalog system is deployed on a single server, and the conference room
reservation system is deployed on multiple servers using the replication function.

A hard disk failure occurred on a mail server, and e-mails of many users were lost. Recovery of data was attempted, but e-mails sent and received during the two-week period after the last backup could not be restored because backups were only created every two weeks. Taking a lesson from this incident, a measure is to be implemented to allow restoration up to the state of the day before such a failure. Which of the following is an appropriate measure? a) Performing daily incremental backup in addition to biweekly (every two-week) full backup b) Accumulating e-mails on multiple different hard disks in a distributed manner c) Implementing hard disk mirroring on the mail server for higher reliability, without changing the existing backup schedule d) Storing daily backup onto the same hard disk media, and a biweekly (every two-week) copy of the backup to another storage media

If any tampering is detected, the packet is discarded. c) A packet with a dynamically allocated TCP port number is permitted to pass through to the internal network by converting the packet to one with a fixed TCP port number on the receiver side. d) Only packets with a specific TCP port number are permitted to pass through to the internal network from the Internet.
