Top CCNA DevNet Interview Questions and Answers
When you have finished your CCNA DevNet training, you become a suitable candidate to apply for network automation job roles. Suppose you are preparing for Network Automation engineer interviews. In that case, you should know that in addition to the standard interview questions, you will get to face technical questions evaluating your skills, knowledge related to the subject and tools that you have expertise in. So, these are some of the few CCNA DevNet Interview Questions and Answers that will help you prepare for the technical part of your interview. The key to succeeding in the job interview process is preparation. However, it might be challenging to plan when you don’t know what kinds of questions to expect. Here is a guide to help you get ready for some typical interview questions you might get. Our trainers and placement officers, who are among the brightest minds in the DevNet track and have already assisted thousands of network automation engineers in getting trained and placed, have curated these questions to help you prepare best for your interviews. CCNA DevNet, short for Cisco Certified Network Associate DevNet, is a certification program offered by Cisco Systems that focuses on network automation and programmability. It is designed for professionals who want to enhance their skills in software development, automation, and networking technologies. CCNA DevNet provides a comprehensive understanding of software development and networking concepts, allowing individuals to build and manage applications and infrastructure in modern networked environments. This certification covers a wide range of topics, including programming fundamentals, APIs, software-defined networking (SDN), network automation, and security. So, let’s take a look at the questions you can expect to hear from any interviewer. Make sure your knowledge is thorough for these questions to impress the interviewers. Here are the top 15 CCNA DevNet Interview Questions and Answers: BASH stands for Bourne Again Shell. It is a free and improved version of the Bourne Shell included with the Linux and GNU operating systems. It is identical to the original version; it has some additional features like Command-line editing. BASH is used for testing, configuring, and optimizing network performance on enterprise networks. The range() function in Python allows to set a range that is up to but not including the number specified. If you want to increment to 10, you need to provide the number 11. Based on the sign of the number provided, the range() function can also count up or down. The key components of object-oriented programming in Python are functions that can be performed on a data structure and attributes that are stored in an object. By using inheritance, you can specify a base class and create a new class with the preceding one as a base parent. The following class contains all the parent class’s capabilities and can add or override any attribute or method that needs to be different. In order to open a file for writing, you need to use the open() function and assign it to a file handler variable—in this case, data. In addition, you need to pass the name of the file and tell Python that you want to allow write access to it (using “w”). To load a native JSON file into a Python string object, loads() is used, which stands for load string. To convert a Python string into native JSON, dump() is used. Answer – The features of a good SDK are as follows: Some of the advantages of using an SDK are quicker integration, faster and more efficient development, brand control, increased security, and the availability of metrics. Cisco DNA Center allows customers to have their non-Cisco devices managed by DNA Center through a multivendor SDK. Device packages are how the third-party devices and Cisco DNA Center communicate. The multivendor SDK is used to create the device packages, which implement southbound interfaces based on the CLI, SNMP, or NETCONF. The Cisco UCS Python module for UCS Manager is called ucsmsdk. It can be installed using pip by issuing the following command at the command prompt: pip install ucsmsdk The Intersight API is a programmatic interface to the Management Information Model similar to Cisco ACI and Cisco UCS Manager. Just like Cisco ACI and Cisco UCS Manager, the Cisco Intersight Management Information Model is comprised of managed objects. A keyId and a keySecret make up an Intersight API key. Each HTTP request delivered to the Intersight web service is cryptographically signed by the API client using the API key. There are usually two types of approaches to infrastructure as code: declarative and imperative. The declarative approach defines the system’s desired state, and then the system goes through all the necessary motions to achieve that state. According to the imperative method, a specific sequence of orders must be carried out in order for the system to reach the target state. The NSO Device Manager manages network devices using YANG data models and NETCONF. For devices that natively implement NETCONF and YANG models, the device manager is automatic, and devices that do not support NETCONF are integrated in the platform by using Network Element Drivers (NEDs). Some of the benefits of using DHCP instead of manual configurations are: The main role of NTP is to synchronize the time on a network of devices. NTP was created by the IETF, and RFC 5905 contains the definition of the protocol’s fourth version. At the transport layer, User Datagram Protocol (UDP) is used, and port 123 is set aside for NTP. Answer – If DNS is malfunctioning for some reason, end-to-end connectivity is impacted. Troubleshooting DNS functionality can be done with the use of network tools like nslookup.
