A security administrator needs to add fault tolerance and load balancing to the connection from the file server to the backup storage. Which of the following is the best choice to achieve this objective?
-A is correct
the best choice to achieve fault tolerance and load balancing for the connection from the file server to the backup storage is A. Multipath.
Multipath is a technique that uses multiple paths between two devices to provide fault tolerance and load balancing. With Multipath, if one path fails, traffic is automatically rerouted to the available path, ensuring high availability and data access. It also provides load balancing by distributing traffic across multiple paths, reducing congestion on individual links and improving performance.
A- Multipath is a fault-tolerant technique used to enhance network reliability. It involves the use of multiple physical connections between two devices, providing redundancy in case one of the paths fails. It also improves performance by load balancing the traffic across the multiple paths.
-RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disks into a single logical unit to provide redundancy and improve performance. However, RAID does not provide fault tolerance or load balancing for network connections.
-Segmentation is a network design technique that involves dividing a network into smaller segments to reduce network congestion and improve security. However, segmentation does not provide fault tolerance or load balancing for network connections.
-802.11 is a family of wireless networking standards commonly known as Wi-Fi. It is not applicable in this scenario as it is a wireless technology and does not provide fault tolerance or load balancing for wired network connections.
Multipath - Another method to add redundancy to data or disks is to use multipath, also known as multipath I/O. Multipath is the creation of multiple pathways to access data wherever it may be stored. For example, if you store data on a SAN, your server may have multiple fiber channel controllers connected to the SAN, which is made up of multiple switches so that there are multiple pathways to access the data on the SAN."
