A computer network comprises two or more computers that are connectedeither by cables (wired) or WiFi (wireless)with the purpose of transmitting, exchanging, or sharing data and resources. Counter logs. From a security perspective, compromise of the name resolution function can lead to an attacker redirecting requests from your sites to an attacker's site. Azure Virtual Networks Interview Question-Answer Part 1 Some of the use cases for analyzing and monitoring network traffic include: Not all tools for monitoring network traffic are the same. In a client/server network, a central server or group of servers manage resources and deliver services to client devices in the network. However, knowing how to monitor network traffic is not enough. [1] It is used by network administrators, to reduce congestion, latency and packet loss. You can gain the benefits of network level load balancing in Azure by using Azure Load Balancer. The remaining bandwidth can then be assigned to other types of traffic. IP is commonly paired with TCP to form TCP/IP, the overall internet protocol suite. The network is a critical element of their attack surface; gaining visibility into their network data provides one more area they can detect attacks and stop them early. Together, IP sends packets to their destinations, and TCP arranges the packets in the correct order, as IP sometimes sends packets out of order to ensure the packets travel the fastest ways. While its true that switches operate at Layer 2, they can also operate at Layer 3, which is necessary for them to support virtual LANs (VLANs), logical network The internet, online search, email, audio and video sharing, online commerce, live-streaming, and social networks all exist because of computer networks. For example, a LAN may connect all the computers in an office building, school, or hospital. This is used by people and devices outside of your on-premises networks and virtual networks. There are a number of topologies but the most common are bus, ring, star, and mesh: A bus network topology is when every network node is directly connected to a main cable. Network traffic refers to the amount of data moving across a network at a given point of time. 2 C. 3 D. 4 Ans : 3 Q.7 Which of the following are load balancer types? This exposes these connections to potential security issues involved with moving data over a public network. The collector or analytics tool is provided by a network virtual appliance partner. How to Reserve an IP Address for a Device, Based on its MAC address? , WAN (wide area network):As the name implies, a WAN connects computers over a wide area, such as from region to region or even continent to continent. https://learn.microsoft.com/en-us/azure/hdinsight/control-network-traffic You can collect network statistics and troubleshoot application issues, which can be invaluable in the investigation of network intrusions. Segmentation works by controlling the flow of traffic within the network. For a complete overview of load balancers, see Load Balancing: A Complete Guide. Service endpoints are another way to apply control over your traffic. Security Group View helps with auditing and security compliance of Virtual Machines. Storage Firewalls are covered in the Azure storage security overview article. Names used for internal name resolution are not accessible over the internet. The process begins with asking the right questions: What applications are users running, and what is the performance service-level agreement for these applications? Download your free guide now.
