Hire Cisco Developers

Tools and systems for networking and telecommunications

Anyone who understands anything about software development knows that the landscape constantly changes and evolves at an incredible pace. New technologies emerge all the time while many existing technologies and practices fade away, especially those related to communication and collaboration. In fact, there are many platforms that fuel the partnership of developers and business teams.

The Cisco Systems Corporation is one of the most popular and most well-known names in the world of communication. The tech company isn’t just known for their networking hardware in both professional and personal user settings, but they also offer collaborative platforms such as Cisco Webex, developer training and certification programs including the popular Cisco DevNet, and many other products.

Over the past several years, Cisco slowly started transitioning itself into a software development company, introducing the Cisco Spark and Cisco DevNet platforms. With this, the company widened its horizons and became even more relevant in the tech industry.

Cisco Developers Hiring guide

While most professionals know Cisco as the company ruling the communication industry and network equipment manufacturing, and working to enhance the Internet of Things, its certifications and developers are now more in-demand than ever. Modern software development depends on effective communication, collaboration, and information sharing across teams, making it understandable for Cisco to make its way into development.

Cisco Webex, formerly known as Cisco Spark, allows every single member of a development team to easily communicate on a single platform. Cisco engineers help integrate the necessary tools and technologies into the platforms for faster and easier development, testing, and app implementation.

A Cisco developer plays a vital role in making sure business operations run smoothly throughout the software development process. They do so through the development, maintenance, and operations of and on the Cisco platforms and tools. Cisco developers have access to many tools and platforms to help with the development of software applications for many different types of network nodes and the newer Internet of Things products and tech.

Developers choosing to specialize in Cisco products go through a certification and training program from Cisco called DevNet. It’s designed for both network professionals and software developers alike to help optimize their skills, write new network applications, and learn how to choose the technology skills they want to develop.

During this program, developers also train and get certified in Cisco’s various areas of specialty, such as data center products, mobility, software-defined networking, mobility, and others. DevNet is the most current certification but they also offer Cisco Certified Network Associate (CCNP) and Cisco Certified Internetwork Expert (CCIE) tracks.

As the Internet of Things and big data projects increase in popularity and adaptability, the demand and need for Cisco engineers also goes up. This also means that demand is currently more than supply, therefore companies currently experience higher salaries and cost to hire (and maintain) these trained professionals.

Interview Questions

When and why does network congestion happen?

When applications send more data than network devices, such as switches and routers, have the ability to accommodate, network congestion occurs. This then causes the buffers located on these devices to build up quickly and sometimes even overflow. A buffer is a portion of a device’s memory set aside as a temporary holding area for data as it comes in or out.  This data is then sent to or received from another device. However, buffering can lead to delayed or lost packets. The applications then retransmit the data, which ends up adding even more traffic and further worsens congestion.

What are the features of IP access lists?

There are 3 different types of access lists: standard, extended and named. They are beneficial in the following ways:
Block unwanted users or traffic
Authenticate incoming requests (including rsh and rcp)
Control access to vty
Limit debug command output
Provide bandwidth and NAT control
Trigger dial-on-demand calls
Help prevent DoS cyberattacks
Restrict routing update content

What’s the default TCP session timeout for Cisco products?

A TCP timeout session for Cisco is 1 minute and the connection slots free up after a normal connection close sequence. Developers may configure other settings depending on their requirements. They also have the ability to set a global idle timeout duration for the connection and translation slots of various protocols. Resources return in order to free the pool if the slots aren’t used for the specified idle times.

Explain the process of a TCP connection.

Step 1: The sender and receiver synchronize to make a connection. Both of the operating systems involved stay informed of the established connection. 

Step 2: The sending party begins transmitting data and receives acknowledgments. As soon as the sender begins sending the data, a timer starts.

Step 3: The sender retransmits data if they haven’t received any acknowledgment even after the timer ends.

Step 4: If the buffer on the receiver is full and creates a case of windowing, the receiver sends a stop signal to the sender, who then stops the data transmission. Step 5: After processing all data, the receiver sends a go signal to the sender to restart data transmissions.
