• find /var -name "*.log"
• mv "*.log"

Where is the iSCSI protocol typically used?

Where is the iSCSI protocol typically used?

• File sharing
•  SANs (Storage Area Networks)
• Inter-site routing
• Internal drive arrays 

 

EXPLANATION

iSCSI (Internet Small Computer System Interface) works on top of TCP and allows SCSI
commands to be sent over a network to iSCSI storage devices. This allows for a low cost SAN infrastructure using standard network hardware.

What is the advantage of coaxial cable over STP or UTP?

What is the advantage of coaxial cable over STP or UTP?

• It can run for a longer distance unboosted
• It is easier to splice.
• It is less expensive
• It is easier to install because it is so flexible 

 

EXPLANATION

Coaxial cable conducts the electrical signal using an inner conductor (usually copper) surrounded by an insulating layer. The whole works are enclosed by a one to four layer shield. This makes coaxial cable thicker than STP or UTP, so harder to install and splice. It also makes it more expensive. But, it has the advantage of being able to carry large quantities of data over a longer distance unboosted.

When replacing a damaged Chromebook in the Google GSuite admin console, what license allows you to reuse a license for the same model Chromebook?

When replacing a damaged Chromebook in the Google GSuite admin console, what license allows you to reuse a license for the same model Chromebook?

• Annual
• KMS
• Perpetual
• MAK 

 

EXPLANATION

Google allows a Google GSuite console to move licenses to a different Chrome device, but there are differences. There are a Annual and Perpetual. Perpetual licenses are a one time purchase for a single type of device. If that device breaks and is replaced with the same model, you can transfer the license to that device. If you would replace it with a different type and model of device, you would have to purchase an additional license.
An annual license is bought per term and in the case of this, you can transfer the license to any new devices, regardless of the model and type during the license term.
Also, different versions of GSuite support different licensing models. GSuite Enterprise supports Annual and Perpetual, whereas GSuite Education and GSuite Nonprofit only supports Perpetual.

• Icinga 

 

EXPLANATION

Nagios Core is a free and open source computer-software application that monitors systems, networks and infrastructure, initially released in 1999.
Icinga is an open source computer system and network monitoring application. It was originally created as a fork of the Nagios system monitoring application in 2009.
Naemon is an open source computer system monitoring, network monitoring and infrastructure monitoring software application. Initial release 2015 and based on Nagios 4 core.
Shinken is an open source computer system and network monitoring software application. Released as a fork of Nagios in 2009.
Check_MK is an extension to the Nagios monitoring system that allows creating rule-based configuration using Python and offloading work from the Nagios core to make it scale better, allowing more systems to be monitored from a single Nagios server. Initial release 2008.
