 What is Power BI, and what are its key components? Answer: Power BI is a business intelligence and data visualization tool by Microsoft. Its key components include Power Query for data transformation, Power Pivot for data modeling, Power View for interactive reporting, and Power Q&A for natural language querying. What are the different versions of Power BI, and how do they differ? Answer: Power BI comes in three main versions: Power BI Desktop (for report creation), Power BI Service (for sharing and collaboration), and Power BI Mobile (for mobile access). There is also a Power BI Pro license for sharing reports and a Power BI Premium license for dedicated resources and on-premises use. Explain the concept of data modeling in Power BI. Answer: Data modeling in Power BI involves creating relationships between tables, defining calculated columns and measures, and organizing data to build a data model that can be used for interactive reporting and visualization. How can you import dat

 What is GPON? Answer: GPON stands for Gigabit Passive Optical Network. It is a high-speed broadband access technology that uses optical fibers to deliver internet and other services to residential and business users. What are the key components of a GPON network? Answer: The key components of a GPON network include the Optical Line Terminal (OLT), Optical Network Terminal (ONT), Optical Distribution Network (ODN), and passive optical splitters. Explain the role of the Optical Line Terminal (OLT) in a GPON network. Answer: The OLT is the central component of a GPON network. It connects to the service provider's core network and manages the distribution of data to multiple ONTs. It also communicates with the ONTs to control the transmission of data and provide services. What is the purpose of the Optical Network Terminal (ONT) in GPON? Answer: The ONT is the customer-side device in a GPON network. It connects to the customer's premises and converts optical signals into electrica

 Q.What is FTTH, and how does it differ from traditional broadband connections? Answer: FTTH stands for Fiber to the Home, a technology that delivers high-speed internet, television, and phone services by connecting homes directly to the internet service provider's network using optical fiber. Unlike traditional broadband, which relies on copper cables, FTTH offers significantly higher speeds and greater reliability. Q.What are the key advantages of FTTH over other types of internet connections? Answer: FTTH offers several advantages, including faster and more consistent internet speeds, lower latency, improved reliability, and the ability to support a wide range of services simultaneously, such as high-definition video streaming, online gaming, and IoT devices. Q.What are the components of an FTTH network? Answer: An FTTH network comprises several key components, including the Optical Line Terminal (OLT) at the service provider's end, optical fibers, distribution and drop cabl

 Interview Question And Answer For Microwave Link Design Planner Engineer 1.Can you explain the concept of Fresnel zones and their importance in microwave link design? Fresnel zones are concentric ellipsoidal regions around the line of sight (LOS) between two microwave antennas. These zones play a crucial role in microwave link design. Clearing the Fresnel zones is essential because they ensure that the majority of the signal energy between the antennas arrives at the receiver without interference. Obstacles within the Fresnel zones can cause signal attenuation, signal degradation, and even link failure. Therefore, microwave link engineers must ensure that the Fresnel zones are clear of obstructions to maintain link reliability. 2.What are the key factors that affect the propagation of microwave signals, and how do you account for them in link budget calculations? Several key factors influence microwave signal propagation, including free space path loss, atmospheric absorption, rain at
