CompTIA CLO-002 Dumps Questions Answers

Audit and system logs are the best resource to use to start the investigation of an email phishing campaign against a company’s email server. Audit and system logs are records of events and activities that occur on a system or a network, such as user login, file access, configuration changes, or network traffic. Audit and system logs can help an incident response team to identify the source, scope, and impact of the phishing attack, as well as to collect evidence, trace the attack steps, and determine the root cause. Audit and system logs can also help the incident response team to evaluate the security posture and controls of the email server, and to recommend remediation and mitigation actions12

Big Data is a term that refers to data sets that are too large, complex, or diverse to be processed by traditional methods1. Big Data is characterized by four V’s: volume, variety, velocity, and veracity2. Volume refers to the amount of data being generated and collected. Variety refers to the different types of data, such as structured, unstructured, or semi-structured. Velocity refers to the speed at which the data is created, processed, and analyzed. Veracity refers to the quality and reliability of the data.

A software-defined network (SDN) is a network architecture that allows for the management of network policies from a central portal while maintaining a hardware-agnostic approach. SDN separates the control plane, which is responsible for making decisions about how to route traffic, from the data plane, which is responsible for forwarding traffic based on the control plane’s instructions. SDN enables network administrators to configure, monitor, and manage network devices and services using a software application, regardless of the vendor or type of hardware. SDN also provides automation, programmability, scalability, and flexibility for network operations. A virtual private network (VPN) is a network technology that creates a secure and encrypted connection over a public network, such as the Internet. A VPN allows remote users to access a private network and its resources securely. A VPN is not related to the management of network policies from a central portal or the hardware-agnostic approach of SDN. Load balancing is a network technique that distributes traffic across multiple servers or devices to optimize performance, reliability, and availability. Load balancing can be implemented using hardware or software, but it does not provide the same level of centralized management and control as SDN. Direct Connect is a service offered by some cloud providers that allows customers to establish a dedicated network connection between their on-premises network and the cloud provider’s network. Direct Connect bypasses the public Internet and provides lower latency, higher bandwidth, and more consistent network performance. However, Direct Connect is not a generic network architecture that supports a hardware-agnostic approach, and it does not offer the same degree of network programmability and automation as SDN. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 4: Cloud Design Principles, Section 4.2: Cloud Network Concepts, Page 1051 and What is software-defined networking (SDN)? | Cloudflare
