10+ Network Analyst Interview Questions and Answers

A modem is a device that connects a computer to the internet through a telephone or cable line. Wireless technology enables devices to connect to a network without the need for physical cables.

• A modem is a hardware device that modulates and demodulates signals to transmit data over a communication channel.

• It allows computers to connect to the internet by converting digital data into analog signals that can be transmitted over telephone or cable lines.

• Wireless technology uses ...read more

Networking is the practice of connecting computers and other devices to share resources and information.

• DHCP stands for Dynamic Host Configuration Protocol, which automatically assigns IP addresses to devices on a network.

• DNS stands for Domain Name System, which translates domain names into IP addresses to locate resources on the internet.

• Routing involves determining the best path for data packets to travel between networks, while switching involves forwarding data within a n...read more

Yes, HSRP can be used on Juniper devices.

• HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol for providing redundancy in a network.

• Juniper devices use a similar protocol called VRRP (Virtual Router Redundancy Protocol) for achieving the same functionality.

• VRRP is an open standard protocol that is compatible with HSRP.

• Both HSRP and VRRP allow for the creation of a virtual IP address that can be shared among multiple routers.

• This virtual IP address acts as the de...read more

Switches are used in networks to connect multiple devices and enable communication between them.

• Switches allow devices to communicate within a local area network (LAN).

• They forward data packets to the intended recipient based on MAC addresses.

• Switches provide dedicated bandwidth to each connected device, improving network performance.

• They support full-duplex communication, allowing simultaneous data transmission and reception.

• Switches can be managed or unmanaged, with managed...read more

Java is a high-level programming language known for its portability, security, and object-oriented features.

• Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)

• It is object-oriented, allowing for the creation of reusable code and modular programs

• Java is known for its security features, such as sandboxing to prevent malicious code execution

• Basic concepts in Java include classes, objects, inheritance, polymorphism, and encapsulation

Working procedure on outages involves identifying the issue, troubleshooting, and resolving the problem.

• Identify the issue through monitoring tools or user reports

• Troubleshoot the problem by analyzing logs and network configurations

• Resolve the issue by implementing a solution or escalating to higher-level support

• Communicate updates and resolution to stakeholders

• Perform post-mortem analysis to prevent future outages

A router is a networking device that forwards data packets between computer networks. MAC address is a unique identifier assigned to network interfaces for communications.

• A router operates at the network layer of the OSI model.

• It uses routing tables to determine where to forward data packets.

• MAC address stands for Media Access Control address.

• It is a hardware address that uniquely identifies a device on a network.

• MAC addresses are usually represented as six groups of two hexa...read more

BGP and OSPF are routing protocols used in computer networks.

• BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems (AS).

• OSPF (Open Shortest Path First) is used to find the shortest path between routers within the same autonomous system (AS).

• BGP is a path-vector protocol while OSPF is a link-state protocol.

• BGP is used in large-scale networks while OSPF is used in smaller networks.

• BGP is more complex and requires more configu...read more

Networking is the practice of connecting computers and other devices to share resources and information.

• Networking involves the physical connection of devices through cables or wireless connections.

• It also includes the configuration of network settings to enable communication between devices.

• Networking allows for sharing of resources such as files, printers, and internet connections.

• Examples of networking technologies include Ethernet, Wi-Fi, and TCP/IP.

• Networking can be done...read more

OSI layers refer to the Open Systems Interconnection model, which is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers.

• The OSI model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and interacts with adjacent layers to facilitate communication between devices.

• For example, the Physical layer deals with the physic...read more
