What are Cisco Core Platforms?

Cisco core platforms, which include a range of technologies and services, serve as the cornerstone upon which network applications are constructed. These platforms give customers access to Cisco’s development tools and APIs for designing, implementing, and automating network solutions. Enterprise networking, security, cloud and data center networking, and service provider networking are important domains.

 

What is the Cisco-350-901 Devcor Exam?

The Cisco-350-901 DevNet Professional certification consists of a required core exam and one specialized concentration exam. This combination is excellent because it demonstrates that you have both foundational knowledge and a focus in a particular field.

The core exam (Cisco-350-901 DEVCOR) assesses your skills in the following areas: software development practices and tools, API design and execution, app security, infrastructure as code, and some automation. The Cisco-350-901 exam consists of multiple-choice, drag-and-drop, and modeling questions that mimic real-world situations; you have 120 minutes to finish all of the questions, so time management is crucial. Cisco does not specify the exact passing score, and it varies between Cisco-350-901 exam versions.

To pass 350-901 -Training & Certifications, you must possess practical expertise. You might have to examine code samples, search for security flaws, or determine which API call is appropriate for a given activity. It is imperative that you practice with real-world examples prior to the Cisco-350-901 test in order to avoid being irritated and stuck on a question.

Best Practices for Cisco-350-901 DevNet Exam

A clever study strategy, a lot of effort, and perseverance are required to pass the core and focus Cisco-350-901 examinations. The following advice will help you make the most of your study time.

 

1. Establish a Methodical Study Schedule

Determine the Cisco-350-901 exam subjects and allot study time according to the importance of each topic. Plan several short study sessions rather than packing them in too close to the deadline; treat this like a marathon rather than a sprint. Large quantities of Cisco-350-901 exam work may be divided into smaller, easier-to-manage chunks with the use of a study plan.

 

2. Make Use of Active Labs

While theory plays a role in the Cisco-350-901 exam, reading about APIs and automation won’t suffice. Practice, practice, practice is essential. Establish a laboratory setting if you can so that you can:

• Create Python programs to perform things automatically.
• Use Postman to make API calls to actual Cisco devices.
• Use Docker to create and launch containers.
• Build infrastructure as code releases.

You will struggle on the Cisco-350-901 exam day if you comprehend the material but are unable to put it into practice. Putting the theory into practice will be aided by carrying out the real work in labs.

 

3. Exam Topics and Blueprints Review

Cisco releases exam blueprints with broad instructions and explanations. Continue going over the Cisco-350-901 exam blueprint frequently to ensure that you have covered all the material required to ace the Cisco-350-901 exam.

 

4. Make Use of Online Communities

GitHub groups built on network automation subjects, DevNet community events, and the 350-901 -Training & Certifications are some excellent starting points. Online forums may respond to your inquiries, offer guidance on Cisco-350-901 exam study materials, and motivate you to continue learning and polishing your skills.

 

5. Regularly Assess Your Knowledge

Although it may be tempting to wait until the very end to assess your progress, you should make an effort to analyze how well you retained the material during your study. Get used to the exam style and use Cisco-350-901 exam practice tests to identify knowledge and ability deficiencies early.

Cisco-350-901 DevNet Professional Exam Sample Questions and Answers

Now is the time we discuss the main Cisco-350-901 exam dumps sample questions before you buy it from our website.

 

Question 1:

Based on the needs of the client, a developer has produced an application. The program must be used by the client with the least amount of downtime.

Which design strategy should be used for high-availability applications in terms of Recovery Time Objective, Recovery Point Objective, and Recovery Time Objective?

1. Lower RTO and RPO are the effects of active/passive. For RPO to function well, rapid data synchronization between the two data centers is required.
2. Lower RTO and RPO are the outcome of active/passive. RPO does not need quick data synchronization between the two data centers in order to facilitate smooth request flow.
3. Lower RTO and RPO are the outcome of active/active. RPO does not need quick data synchronization between the two data centers in order to facilitate smooth request flow.
4. Lower RTO and RPO are the outcome of active/active. For RPO to function well, rapid data synchronization between the two data centers is required.

 

Question 2:

Which two load-balancing strategies maximize the user experience of an application that has both a simple search feature and a video upload function? Select two.

1. An intermediary hop should be used to redirect video upload requests to the destination.
2. The endpoint with the lowest round-trip latency should receive search queries.
3. The endpoint with the lowest round-trip latency should get requests for video uploads.
4. The endpoint with the greatest data throughput should receive requests for video uploads.
5. The endpoint with the highest data throughput should receive search queries.

 

Question 3:

A big cloud-deployed application using a microservices architecture is managed by an organization. Because this application’s services are redundantly deployed across three or more data center regions, there are no noticeable downtime concerns. Nonetheless, complaints regarding application lag are received many times each week. Faults in various containers as a result of them to, fail and then spinning up again are seen in the container orchestration logs.

What steps need to be performed to keep the application’s existing scale while improving its resiliency design?

1. Update the containers’ base image.
2. Use a different cloud service platform to test how the application runs.
3. Boost the number of containers operating for each service.
4. Make sure the code has consistent {^€try/catch(exception){�€ clauses.

 

Question 4:

The logging dashboard is showing these notifications, and users claim that they are no longer able to execute transactions using the online ordering application.

Fri., January 10, 2020, 19:37:31.123 EST [FRONTEND] INFO: User 45834534858 has requested to add an item to their cart.

Fri., January 10, 2020, 19:37:31.247 EST [BACKEND] INFO: Trying to put anything in the cart

Friday, January 10, 2020, 19:37:31.250 EST [BACKEND] ERROR: The item was not added. MySQL and MySQL Database ERROR: No connection was made.

What’s causing the issue that these log messages show?

1. The container for the database server has crashed.
2. There are too many transactions overloading the backend process.
3. The database cannot be committed to by the backend.
4. Adding the item to the user’s cart is not permitted.

 

Question 5:

A company oversees a sizable cloud-deployed application that uses several data centers and a microservices architecture. There have been complaints regarding the speed of the application. Faults have been reported in a number of containers, causing them to fail and then spin up new instances, according to the container orchestration logs.

Which two steps may be taken to enhance the application’s design and find its flaws? Select two.

1. Automatically remove the container that experiences the most failures over time.
2. Put in place a tagging technique that tracks how an application is executed across services.
3. Include an exception for logging on and give prompt notice.
4. In the event that an application fails, write to the datastore.
5. Put in place an alert-equipped SNMP logging system in case a network link is sluggish.
