Examen AZ-400 (beta): Microsoft Azure Devops Solutions
¡Hola! En esta entrada te comento que Microsoft ha publicado un nuevo examen de certificación para los interesados en certificarse como DevOps Engineer. El examen en cuestión es el AZ-400 Microsoft Azure DevOps Solutions, el cual se encuentra en su versión beta.
Este examen es ideal para aquellos profesionales que se encargan del proceso de entrega continua de soluciones y servicios valiosos para personas, procesos y otras tecnologías. ¿Temas como Integración Continua (Continuous Integration) y Entrega Continua (Continuous Deployment) te son familiares? ¿Utilizas o quieres aprender sobre prácticas Agile? ¿Utilizas o utilizaste VSTS, HockeyApp, Docker, Kubernetes y tecnologías en la nube? Pues este examen cubre varios de esos temas.
La ventaja del examen beta es que puedes obtener un descuento del 80% aplicando el código AZ400PjM al momento de hacer el ckechout. El precio final quedaría en 20 dólares aproximadamente (precio varía dependiendo la región) peeeeero si eres estudiante o académico recuerda que puedes obtener una reducción en el precio (en mi caso por ejemplo, el precio final fue de 12 dólares). Solo hay dos reglas:
- Hay 300 códigos disponibles en todo el mundo. Así que si te interesa realizarlo, aprovecha mientras es válido.
- El examen lo debes realizar como máximo el día 5 de diciembre.
Aquí explico cómo introducir el código y aquí explico el proceso a seguir para obtener el descuento de estudiante/académico. Ah, por cierto, esta información fue publicada originalmente en el Blog de Microsoft Learning.
Antes de mencionar los temas del examen y sus respectivos links, te comento que los siguientes son recursos gratuitos donde puedes aprender sobre DevOps y que además incluyen varios de los tópicos de la evaluación:
- Jumpstart en español: DevOps para IT Pros y desarrolladores en español
- Webinar en español sobre Xamarin + DevOps con Cristian y Humberto =)
- Cursos del Microsoft Professional Program in DevOps (nota: cada curso SÍ es gratuito, ya si quieres un certificado éste cuesta 99 USD)
- Overview de Azure sobre DevOps.
- En YouTube, Azure DevOps.
- Otra serie de videos en YouTube sobre Azure DevOps.
Ahora sí, los temas del examen. Por cada uno incluiré una serie de links y recursos donde puedes estudiar para prepararte 😀
(NOTA: Estoy actualizando la publicación frecuentemente para agregar links con material de estudio, así que si vuelves otro día seguro que la entrada estará actualizada =) )
