Exam 6: Linux Server Deployment

If a Linux installation ends abnormally and the screen displays a fatal signal 11 error, what type of error has occurred?

Which two problems below are typically seen on large systems that write large amounts of data to a non-ZFS filesystem?​

You can use a small bootable Linux kernel (such as on a LiveCD) to fix problems related to the following: the boot loader; filesystems and partitions; the configuration file; and drivers.

​Match each correct item with the statement below. a.disk mirroring b.disk striping​ c.​fault tolerant d.GRUB​ e.​Internet SCSI f.iSCSI target​ g.​overclocked h.​spanning i.terminator j.​Zettabyte File System (ZFS) -​A type of RAID level 0 that allows two or more devices to be represented as a single large volume.

​Match each correct item with the statement below. a.disk mirroring b.disk striping​ c.​fault tolerant d.GRUB​ e.​Internet SCSI f.iSCSI target​ g.​overclocked h.​spanning i.terminator j.​Zettabyte File System (ZFS) -​The most common boot loader used on Linux systems. It loads and executes the Linux kernel at boot time.

To view the hardware detected during boot time, you can use the ______________ command after system startup.

​Match each correct item with the statement below. a.disk mirroring b.disk striping​ c.​fault tolerant d.GRUB​ e.​Internet SCSI f.iSCSI target​ g.​overclocked h.​spanning i.terminator j.​Zettabyte File System (ZFS) -Term used to describe a device that exhibits a minimum of downtime in the event of a failure.​

Most Parallel SCSI controllers are capable of supporting up to how many devices?

In a SCSI chain the highest priority SCSI device is given what SCSI ID?

A RAID that is created by the system BIOS is referred to as ___________________.​

​Match each correct item with the statement below. a.disk mirroring b.disk striping​ c.​fault tolerant d.GRUB​ e.​Internet SCSI f.iSCSI target​ g.​overclocked h.​spanning i.terminator j.​Zettabyte File System (ZFS) -​A SCSI technology that transfers data via TCP/IP networks.

Fault tolerant hard disk configurations are typically implemented by a(n) ____________________.

Explain what can be done if a hardware device is not working.

RAID level 6 is basically the same as RAID level 5, but it adds a second set of parity bits for added fault tolerance ​and allows up to two simultaneous hard disk drive failures while remaining fault tolerant.

​Select the command that can be used to change the root filesystem to a different directory, such as when in a rescue environment.

In order to list all configuration parameters that can be modified for a subfilesystem, what command should be issued?​

What file in the /proc directory contains a list of memory address ranges reserved for device use?

Describe RAID level 5. What are the advantages of using RAID level 5 over other types of RAID?

The ​state and performance of a RAID-Z volume can be viewed using what two commands?

What is the term for a ZFS managed filesystem that is created from ZFS pools?​
