The configuration that provides both fault tolerance and consistent performance for applications like streaming audio and video services is option A.) Active/Passive clustering.
What is the Configuration of a computer about?A system's configuration in communications or computer systems refers to how each of its functional elements is organized in relation to their nature, number, and distinguishing features. Configuration frequently involves picking the right hardware, software, firmware, and documentation.
Note that One active server and one passive standby server make up an active/passive cluster. A third-party load balancer determines when a passive legacy failover is necessary and directs users to the appropriate node.
Therefore, When molecules hit the receiver surface in the active model, they are absorbed. The receiver is a hypothetical border that has no impact on the behavior of molecules in the passive model. To determine transformations between the receiver signals, two methods are described.

dan is designing a segmented network that places systems with different levels of security requirements into different subnets with firewalls and other network security devices between them. in which phase of the incident response process is dan working in the given scenario?
Before a system is shut down for imaging, a live response is often employed to gather any volatile evidence and to get a "first look" at the system to see if it needs any further care.
Finding and analyzing electronic data is the process of digital forensics. By gathering, identifying, and confirming the digital material to recreate historical events, the approach aims to preserve any evidence in its most authentic form while carrying out a structured examination. Experts are required to first identify and gather all forensic resources that the organization needs when an accident occurs in order to integrate the forensic procedures into an incident respond strategy of any company.

What is a packet ?In telecommunications and computer networking, a network packet is a structured unit of data delivered via a packet-switched network. A packet is made up of control information and user data, often known as the payload. Control data provides information needed to deliver the payload.
Calculationpacket length = 10k bits

band width = 10 mbps = 10 * [tex]10^{6}[/tex] sec
transmission time = L / b.w. = ( 10 *2^10 )/ (10 * 10^6) = 0.001024 sec.
