Which Statements about Syslog Logging are True?

CE

Syslog logging is a method for collecting and storing system messages from network devices, such as routers, switches, and servers. It helps administrators to diagnose problems and track activity on the network. The syslog messages can be stored either on the device itself or externally on a syslog server.

The correct answers to the question are A and B.

A. The size of the log is dependent on the resources of the device.

The syslog log size depends on the device's resources such as RAM and storage capacity. The device may have a fixed amount of memory for logging or a configurable limit that the administrator can set. If the log size exceeds the device's available resources, the device may stop logging or overwrite the old logs.

B. Messages can be erased when the device reboots.

Syslog messages may be stored in the device's volatile memory, which is erased when the device reboots. If the device is configured to log to an external server, the messages will not be lost when the device reboots.

C. Messages are stored external to the device.

Syslog messages can be stored externally on a syslog server, which is a dedicated server that receives and stores logs from multiple devices. Storing logs on an external server has several benefits, including centralized log management and storage, easier access to logs from multiple devices, and improved security.

D. Messages are stored in the internal memory of the device.

Syslog messages can be stored in the device's internal memory or on a separate flash memory module. The size of the internal memory may be limited, and if the log size exceeds the available memory, the device may stop logging or overwrite the old logs.

E. Syslog logging is disabled by default.

Syslog logging may be enabled or disabled on a device, depending on the device's configuration. Some devices may have syslog logging enabled by default, while others may require manual configuration by the administrator. It is important to configure syslog logging on critical devices to ensure that important events are logged and can be reviewed in case of problems.
