10+ Yarbo Softlab Interview Questions and Answers
Q1. Layers of OSI and explain in detail on packet level.
The OSI model consists of 7 layers that define the functions of a network. Each layer has specific responsibilities in handling data packets.
Physical Layer: Deals with physical connections and transmission of raw data bits.
Data Link Layer: Manages data frames and error detection/correction.
Network Layer: Handles routing and logical addressing.
Transport Layer: Ensures reliable data transfer between devices.
Session Layer: Manages sessions between applications.
Presentation Layer...read more
Q2. Why automation is required in Conference room?
Automation in conference rooms streamlines operations, enhances user experience, and increases efficiency.
Automated control of AV equipment saves time and reduces human error.
Integration with scheduling systems ensures seamless transitions between meetings.
Remote monitoring and troubleshooting capabilities improve maintenance and support.
Automation can enhance user experience by providing intuitive interfaces and personalized settings.
Energy-saving features such as automatic ...read more
Q3. Explain RIP, EIGRP, STP, RSTP, MSTP, LAG.
RIP, EIGRP, STP, RSTP, MSTP, LAG are networking protocols and technologies used in network engineering.
RIP (Routing Information Protocol) is a distance-vector routing protocol.
EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol.
STP (Spanning Tree Protocol) prevents loops in Ethernet networks.
RSTP (Rapid Spanning Tree Protocol) is an updated version of STP for faster convergence.
MSTP (Multiple Spanning Tree Protocol) allows multiple VLANs...read more
Q4. What is the difference between ipv4 and ipv6
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses, allowing for more unique addresses in IPv6.
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses
IPv IPv4 supports 4.3 billion unique addresses while IPv6 supports 340 undecillion unique addresses
IPv4 uses decimal notation for addresses (e.g. 192.168.1.1) while IPv6 uses hexadecimal notation (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334)
IPv6 has built-in security features like IPsec while IPv4 requires additi...read more
Q5. What is osi model and explain it
The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
The OSI model stands for Open Systems Interconnection model.
It helps in understanding how different networking protocols work together.
The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the adjacent layers.
For example, HTTP operat...read more
Q6. How does data flow trough osi model
Data flows through OSI model in a structured manner through different layers.
Data is encapsulated into frames at the Application layer
Frames are then segmented into packets at the Transport layer
Packets are further divided into segments at the Network layer
Segments are converted into bits at the Data Link layer
Bits are transmitted physically through the network at the Physical layer
Q7. A Brief Overview of the OSI Model.
The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
The OSI model stands for Open Systems Interconnection model.
It helps in understanding how data is transferred between devices in a network.
Each layer has specific functions and interacts with adjacent layers.
Examples of layers include Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Q8. Explain OSPF on packet level.
OSPF is a routing protocol that uses link-state algorithm to determine the best path for routing packets.
OSPF routers exchange link-state advertisements (LSAs) to build a topological database of the network.
Each router calculates the shortest path tree to all destinations using Dijkstra's algorithm.
OSPF uses cost metrics to determine the best path, with lower costs indicating faster links.
LSAs are flooded throughout the network to ensure all routers have consistent routing in...read more
Q9. How to read properties File How to take screenshot
To read properties file, use Java Properties class. To take screenshot, use Selenium WebDriver's TakesScreenshot interface.
To read properties file, create an object of Properties class and load the file using FileInputStream.
To take screenshot, cast WebDriver object to TakesScreenshot and call getScreenshotAs method.
Q10. Signal flow of AV system.
Signal flow of AV system refers to the path that audio and video signals take from input sources to output devices.
Input sources such as microphones, cameras, or media players send signals to a mixer or switcher.
The mixer or switcher processes the signals and sends them to amplifiers or processors.
Amplifiers or processors then send the signals to output devices like speakers or displays.
The final output is the audio and video that is heard and seen by the audience.
Q11. Configuration of different models
Configuration of different models involves setting up and customizing various hardware and software components to meet specific requirements.
Identify the specific requirements for each model
Select appropriate hardware and software components
Install and configure the components
Test and validate the configuration
Document the configuration for future reference
Q12. Back history of other company
Discussing the back history of a previous company
Provide a brief overview of the company's founding and early years
Discuss any major milestones or achievements
Explain any significant changes in leadership or direction
Highlight key products or services offered by the company
Mention any notable partnerships or acquisitions
Discuss the company's overall reputation in the industry
Q13. SAP working process
SAP working process involves integrating various business functions through modules like finance, HR, sales, etc.
SAP stands for Systems, Applications, and Products in Data Processing
It helps streamline business processes by integrating various functions
Modules include finance, HR, sales, supply chain management, etc.
Data is stored in a centralized database for easy access and analysis
