Source By: <docs.aws.amazon.com> What Is Elastic Load Balancing? Elastic Load Balancing distributes incoming application traffic across multiple EC2 instances, in multiple Availability Zones. This increases the fault tolerance of your applications. The load balancer serves as a single point of contact for clients, which increases the availability of your application. You can add and… Read more »
Source mc mcse Certification Resources Quality of Service – (QoS) is a set of parameters that controls the level of quality provided to different types of network traffic.
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology.
Multilayer Switch – A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.
Hub – A physical layer network device used to connect multiple Ethernet devices together.
Vertical Cross Connect – is a location within a building where cables originate and / or are terminated, reconnected using jumpers or pass throughs or are connected to patch panels or other similar devices where the locations are from upper or lower floors in the building.
Some of the Security+ exam will test you on your knowledge of some basic email, Internet, and application security issues. Although the amount of detail of knowledge that is required is quite minimal, you must still have a working knowledge of some simple email and application security concepts.
Physical Security Physical security refers to the aspects of information security that are related to physical threats, such as fire or natural disasters. We will cover some basic physical security threats below:
Public Key Cryptography is a widely-applied form of cryptography commonly utilized in many network transactions.
In here we will learn about different symmetric key algorithms and their key features. More importantly, we will learn about some more key concepts related to cryptography as it applies to both symmetric and asymmetric algorithms.
Networking Overview In subsequent chapters of this study guide, we will take a look at different security topologies or ways that networks can be set up with security in mind.
A local area network (LAN) is a critical component of a modern data network. A LAN is comprised of one or more computers, a communication protocol, a network topology, and cabling or a wireless network to connect the systems.
No system or architecture will ever be completely secure; there will always be a certain level of risk.
Security Models of Control Security models of control are used to determine how security will be implemented, what subjects can access the system, and what objects they will have access to. Simply stated, they are a way to formalize security policy.
Although a robust architecture is a good start, real security requires that you have security mechanisms in place to control processes and applications. Some good security mechanisms are described in the following sections.
Wireless encryption protocols include:
Common networking command-line tools include the following:
Bluetooth is a short-range technology aimed at simplifying communications and synchronization among network devices. Bluetooth is divided into three classes:
Wireless Ethernet Versions: (Name – Data Transfer Rate – Frequency)
Cabling Standards include:
Networking Protocols include: FTP – File Transfer Protocol : Port 21
