10+ CAMP Systems International, Inc. Interview Questions and Answers

Floating routing is a technique used to route traffic between two networks without a direct physical connection.

• It involves creating a virtual interface on each network and configuring them to communicate with each other.

• This can be done using protocols such as GRE or IPsec.

• Floating routing can be useful in scenarios where a direct physical connection is not possible or desirable, such as connecting two data centers.

• Configuration can vary depending on the specific network equ...read more

Use alternative network troubleshooting methods like traceroute, netstat, nslookup, and checking firewall rules.

• Use traceroute to identify the path taken by packets and locate any network issues.

• Use netstat to check for open ports and connections.

• Use nslookup to verify DNS resolution.

• Check firewall rules to ensure they are not blocking traffic.

• Use packet capture tools like Wireshark to analyze network traffic.

• Check system logs for any errors or warnings related to network con...read more

OTN stands for Optical Transport Network, a high-speed network technology used for transmitting large amounts of data over optical fibers.

• OTN is a standardized protocol for optical networking

• It uses wavelength division multiplexing (WDM) to increase bandwidth

• OTN supports different types of traffic, including voice, video, and data

• It provides features like error correction, fault management, and network resilience

• OTN is used in long-haul and metro networks, data centers, and c...read more

SDH stands for Synchronous Digital Hierarchy, a standard for transmitting digital signals over optical fiber networks.

• SDH is used for high-speed communication in telecommunications networks.

• It is a standardized protocol for transmitting digital signals at different rates.

• SDH is used to multiplex different signals onto a single fiber optic cable.

• It provides a reliable and efficient way to transmit data over long distances.

• Examples of SDH rates include STM-1 (155 Mbps) and STM-...read more

PSTN is a traditional telephone network that uses copper wires to transmit analog voice data.

• PSTN stands for Public Switched Telephone Network

• It is a circuit-switched network that uses analog signals

• It is being replaced by digital networks like VoIP

• Examples of PSTN services include landline phones and fax machines

MAC stands for Media Access Control. It is a unique identifier assigned to network interfaces for communication.

• MAC address is a 48-bit address assigned to network devices.

• It is used to identify devices on a network.

• MAC addresses are assigned by the manufacturer and cannot be changed.

• MAC filtering is a security feature that allows or denies access to a network based on MAC addresses.

• Example: 00:1A:2B:3C:4D:5E is a MAC address.

Reverse lookup is the process of finding the hostname associated with a given IP address.

• It is commonly used in network troubleshooting.

• It can be performed using the 'nslookup' command in the command prompt.

• Reverse lookup is the opposite of forward lookup, which finds the IP address associated with a given hostname.

Network management involves designing and implementing a system to monitor and control a network's performance.

• Designing a network management system involves identifying the network's components and their interconnections.

• The system must be able to monitor network traffic, identify problems, and alert administrators.

• Network management systems can be centralized or distributed, depending on the size and complexity of the network.

• Phases of network management include planning, i...read more

BGP stands for Border Gateway Protocol. It is a routing protocol used to exchange routing information between different networks on the internet.

• BGP is used to connect different autonomous systems (AS) on the internet.

• It is a path-vector protocol that selects the best path for data to travel between networks.

• BGP is used by internet service providers (ISPs) to connect to each other and exchange routing information.

• It is a complex protocol that requires careful configuration to...read more

Computer languages are used to communicate instructions to computers, allowing programmers to create software and applications.

• Computer languages are used to write code that tells computers what to do.

• There are different types of computer languages, such as high-level languages like Python and Java, and low-level languages like Assembly.

• Each language has its own syntax and rules for writing code.

• Some languages are more suited for specific tasks, such as web development (HTML,...read more
