GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. MBR (Master Boot Record) is an older partitioning scheme that has limitations on the size and number of partitions (up to 4 primary partitions or 3 primary and 1 extended partition per drive). To provision a new 4 TB drive, the technician should partition it using GPT. Verified References: [GPT], [MBR]

RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into a logical unit that provides improved performance, reliability, or capacity. RAID can be implemented by hardware, software, or a combination of both. Hardware RAID uses a dedicated controller to manage the RAID array, while software RAID uses the operating system or a driver to do the same1.

In this scenario, the technician noted that the RAID hard drives were functional while troubleshooting a motherboard failure. This means that the data on the drives was not corrupted or lost. However, the technician installed a spare motherboard with similar specifications and used the original components. This means that the new motherboard may not have the same RAID configuration as the old one, or it may not recognize the existing RAID array at all. Therefore, the technician needs to reconfigure the RAID in order to restore operations with minimal downtime.

An out-of-band (OOB) solution is a method of accessing and managing a server remotely without using the network connection or the operating system of the server. An OOB solution can use a dedicated management port, a serial console, or a KVM switch to provide a resilient connection while performing changes to the network configuration of the server. An OOB solution is more reliable than a VNC or RDP console, which depend on the network and the operating system, and more convenient than a crash cart, which requires physical access to the server.

GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. However, GPT is not compatible with older versions of Windows, such as Windows XP or Windows Server 2003, which use MBR (Master Boot Record) as the partitioning scheme. If a disk uses GPT, it may not be recognized or accessible by an older Windows server. Verified References: [GPT], [MBR]

Robocopy (Robust File Copy) is a command-line tool that can copy files and folders between Windows servers or computers. It has many features and options that can ensure all the data is copied consistently, such as retrying failed copies, resuming interrupted copies, copying permissions and attributes, mirroring source and destination directories, and logging the copy progress and results. Verified References: [Robocopy], [File copy]

Cloud IaaS (Infrastructure as a Service) is a service model that allows users to rent virtualized computing resources over the internet, such as servers, storage, network, and software. Cloud IaaS can provide several benefits for disaster recovery and failover scenarios, such as:

Lower cost: Cloud IaaS can reduce the capital and operational expenses of building and maintaining a physical disaster recovery site, asusers only pay for the resources they use on demand12.

Scalability: Cloud IaaS can offer flexible and elastic scalability of resources, as users can easily provision or deprovision resources according to their needs and workload12.

Availability: Cloud IaaS can ensure high availability and reliability of the application, as users can leverage the cloud provider’s redundant andgeographically distributed infrastructure12.

Simplicity:Cloud IaaS can simplify the failover process, as users can use the cloud provider’s tools and services to automate and orchestrate the failover operations12.

Therefore, building a cloud IaaS and performing a failover of the application would be the most cost-effective solution for the company, as it would allow them to simulate a failover of a critical application on production configurations and IP address schemes without investing in a physical disaster recovery site.

Blanking panels are metal or plastic plates that are installed in the empty spaces of a rack to prevent hot air from recirculating back to the front of the rack. This can improve the airflow and cooling efficiency of the rack and reduce the heat generated by the servers. Verified References: [Blanking panel], [Rack cooling]

A loop is a script construct that allows the script to repeat a block of code until a certain condition is met or for a specified number of times. A loop can be used to apply a test to each file in a directory and move the files that meet the criteria. For example, in a bash script, a loop can be written as:

#!/bin/bash

# Ask the user for the date

echo"Enter the date (YYYY-MM-DD):"

readdate

# Loop through all the files in the current directory

forfilein*

do

# Check if the file was created before the date

if[[ $(date-r"$file"+%F) <$date]]

then

# Move the file to another location

mv"$file"/path/to/destination

fi

done

Copy

A variable is a script construct that allows the script to store and manipulate data. A variable can be used to store the date input by the user, but it cannot apply a test to each file1

A comparator is a script construct that allows the script to compare two values and determine their relationship. A comparator can be used to check if a file was created before the date, but it cannot repeat the test for all files1

A conditional is a script construct that allows the script to execute different blocks of code based on certain conditions. A conditional can be used to decide whether to move a file or not, but it cannot iterate over all files1

The next thing that the technician should do, given the disk is hot swappable, is to replace the disk. A hot swappable disk is a disk that can be removed and replaced without shutting down the system or affecting its operation. A hot swappable disk is typically used in a storage array that has RAID (Redundant Array of Independent Disks) configuration that provides fault tolerance and redundancy. If a disk fails in a RAID array, it can be replaced by a new disk without interrupting the service or losing any data. The new disk will automatically rebuild itself using the data from the other disks in the array.

The action that the server administrator should take once a new backup scheme has been configured is to run a restore test. A restore test is a process of verifying that the backup data can be successfully recovered and restored to its original location or a different location. A restore test can help ensure that the backup scheme is working properly, that the backup data is valid and consistent, and that there are no errors or issues during the recovery process. A restore test should be performed periodically and after any changes to the backup configuration or environment.
