A managed relational database is a type of database that is hosted and maintained by a cloud service provider such as Microsoft Azure or Amazon Web Services. A relational database is a type of database that organizes data into tables that are related to each other by common fields or attributes. A managed relational database would be the best option for allowing multiple users to create and edit reports at the same time because it can handle concurrent user requests, provide high availability and scalability, and perform complex queries and operations on the data. A text file on a shared drive, an informational intranet page, and locally installed productivity software are not options that can allow multiple users to create and edit reports at the same time because they cannot handle concurrent user requests, provide high availability and scalability, or perform complex queries and operations on the data.

質問 # 103
パスワードの有効期限の理由を最もよく説明しているものは次のうちどれですか?
- A. 未使用のユーザーIDを無効にする場合
- B. 新しいパスワードの複雑さのルールを適用するには
- C. 侵害されたパスワードを無効にするため
- D. パスワードのメモを防止するため
正解：C
解説：
Explanation
The best explanation for password expiration is to invalidate any compromised passwords. Password expiration is a security policy that requires users to change their passwords after a certain period of time, such as every 90 days. This reduces the risk of unauthorized access if an attacker obtains the user's password through phishing, hacking, or other means. If the user changes their password regularly, the old password becomes useless for the attacker. Password expiration does not necessarily disable unused user IDs, as the user may still be able to log in with their new password. Password expiration does not discourage writing down passwords, as some users may still do so to remember their new passwords. Password expiration does not enforce new password complexity rules, as those rules apply to any password change regardless of expiration.

The connection type that is typically used for a display monitor is DVI. DVI stands for Digital Visual Interface, which is a standard that defines how digital video signals are transmitted from a source device, such as a computer or a DVD player, to a display device, such as a monitor or a projector. DVI can support various resolutions and refresh rates, depending on the type and length of the cable and the capabilities of the devices.
DVI can also support analog video signals, using a DVI-A connector, or both digital and analog video signals, using a DVI-I connector. However, DVI does not support audio signals, so a separate audio cable is needed.
USB is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for peripheral devices, such as keyboards, mice, printers, scanners, etc. USB stands for Universal Serial Bus, which is a standard that defines how data and power are transmitted between devices using a common interface. USB can support various types and speeds of devices, depending on the version and mode of the USB port and cable. USB can also support video and audio signals, using a USB-C connector, which can be converted to other standards, such as HDMI or DisplayPort. Bluetooth is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for wireless devices, such as headphones, speakers, keyboards, mice, etc. Bluetooth is a technology that defines how data and audio are transmitted between devices using short-range radio waves. Bluetooth can support various profiles and protocols that enable different types of communication and functionality between devices.
Bluetooth can also support video signals, using a Bluetooth Low Energy Video Streaming (BLE-VS) protocol, but it is not widely adopted or supported by most devices. RJ45 is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for network devices, such as routers, switches, computers, etc. RJ45 stands for Registered Jack 45, which is a connector that defines how data are transmitted between devices using twisted pair cables. RJ45 can support various standards and speeds of network communication, depending on the category and length of the cable and the capabilities of the devices. RJ45 can also support video signals, using an Ethernet AVB (Audio Video Bridging) protocol, but it is not widely adopted or supported by most devices.
