What is the primary purpose of Spanning Tree Protocol (STP) in network environments?
The primary purpose of the Spanning Tree Protocol (STP) in network environments is to prevent loops in Ethernet networks. Loops occur when there are multiple active paths between switches in a network, causing broadcast storms and network congestion. STP works by dynamically calculating a loop-free logical topology, allowing for redundant links while ensuring a single

What is the purpose of designating a primary NTP server and a backup server when configuring NTP, and how can the actively used NTP server be determined on a device?
In computer networking, specifically in the context of Routing and Time synchronization within networks, the Network Time Protocol (NTP) plays a important role in ensuring accurate and synchronized timekeeping across devices. When configuring NTP, it is common practice to designate a primary NTP server and a backup server to enhance the reliability and fault tolerance
What can happen to a static route in a routing table if an interface associated with it fails?
In the realm of computer networking, specifically in the context of routing, static routes play a important role in determining how network traffic is directed from one network to another. Understanding the behavior of static routes in routing tables when an associated interface fails is fundamental to maintaining network stability and efficiency. When a static

What is the role of error correction in classical post-processing and how does it ensure that Alice and Bob hold equal bit strings?
In the field of quantum cryptography, classical post-processing plays a important role in ensuring the security and reliability of the communication between Alice and Bob. One of the key components of classical post-processing is error correction, which is designed to correct errors that may occur during the transmission of quantum bits (qubits) over a noisy

How can Denial-of-Service (DoS) attacks disrupt the availability of a web application?
Denial-of-Service (DoS) attacks can significantly disrupt the availability of a web application by overwhelming its resources, rendering it inaccessible to legitimate users. These attacks exploit vulnerabilities in the design and implementation of web applications, causing a temporary or permanent denial of service. Understanding how DoS attacks work is important for web application security professionals to
How does having multiple domain controllers provide fault tolerance in a Windows domain?
Having multiple domain controllers in a Windows domain provides fault tolerance by distributing the workload and ensuring high availability of domain services. A domain controller (DC) is a server that manages security authentication requests, enforces security policies, and maintains the directory database for a Windows domain. By having multiple domain controllers, the domain can continue
