Alerts are notifications that inform the technician or the team of any issues or events that occur on a server or a network. Alerts can be configured to trigger based on certain thresholds, such as CPU usage, disk space, memory utilization, or response time. Alerts can help the technician monitor and troubleshoot the server performance in real time. Verified

A crash cart is a mobile device that consists of a monitor, a keyboard, a mouse, and a network connection. It can be used to access a physical server that is not responding to remote management software or does not have out-of-band management cards configured. The technician can connect the crash cart to the server using a VGA or HDMI cable and troubleshoot the server locally. Verified

A template is a preconfigured virtual machine image that can be used to create new virtual machines quickly and easily. A template can include the operating system, applications, settings, and data that are required for a specific purpose or role. A type 1 hypervisor is a virtualization technology that runs directly on bare metal hardware, without requiring an underlying operating system. A type 1 hypervisor can provide better performance, security, and isolation for virtual machines than a type 2 hypervisor, which runs on top of an operating system. Verified

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

Active-active is a configuration in which both nodes of a redundant system respond to service requests whenever possible. It can improve the performance, availability, and load balancing of the system by distributing the workload among the nodes. However, it also requires more synchronization and coordination between the nodes to avoid conflicts or errors. Verified

The hosts file is a file that maps hostnames to IP addresses on a server or a computer. It can be used to override or supplement the DNS (Domain Name System) resolution for certain hosts or domains. If the hosts file is misconfigured, it may return a different IP address for a hostname than the one registered in the DNS server, causing connectivity issues or errors. Verified

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

Push notifications are messages that are sent from an application or a service to a user's device without requiring the user to open or request them. They can be used as a cost-effective technique for implementing MFA (Multi-Factor Authentication) on servers by sending verification codes or approval requests to the user's smartphone or tablet when they try to log in to the server. Verified

Link aggregation is a technique that combines multiple physical network links into one logical link with higher bandwidth and redundancy. It can take advantage of all the available bandwidth of the NICs (Network Interface Cards) on the server and provide load balancing and failover capabilities for network traffic. Verified
