Introduction
Certainly! If you are preparing for Google Cloud Platform (GCP)-related interviews, it is essential to have a good understanding of the various aspects of GCP, including its services, architecture, deployment models, pricing, security, and best practices. Here are 15 must-know GCP interview questions for 2024 that can help you enhance your knowledge.
GCP interview questions
Here are 15 must-know GCP interview questions given below
Computer Services:
1) What are the primary compute options available in GCP?
The major compute alternatives to GCP are Google Compute Engine (GCE) for virtual machines, Google Kubernetes Engine (GKE) for containerized applications, and Google App Engine for serverless application deployment. Each option provides scalability, flexibility, and managed services optimized for specific workload needs.
2) Explain the difference between Google Compute Engine (GCE) and Google Kubernetes Engine (GKE).
The Google Compute Engine (GCE) provides virtual machines (VMs) to run applications, giving you complete control over the infrastructure. Google Kubernetes Engine (GKE) is a managed Kubernetes service that handles container orchestration, scaling, and management. GKE separates infrastructure concerns, making it easier to deploy and operate containerized applications on a large scale.
3) How does Google App Engine differ from GCE and GKE?
Google App Engine is a Platform-as-a-Service (PaaS) solution that abstracts infrastructure administration, allowing developers to focus exclusively on code deployment. Google Compute Engine (GCE) and Google Kubernetes Engine (GKE) are IaaS and container orchestration technologies, respectively, that give you more control over infrastructure configuration and administrative duties.
Storage:
4) What storage options are available in GCP?
Google Cloud Platform offers a variety of storage options, including cloud storage for object storage, cloud SQL for relational databases, cloud Bigtable for NoSQL databases, cloud Spanner for globally distributed databases, and cloud Filestore for file storage. Is included. These services meet a wide range of storage needs while remaining scalable, reliable, and efficient.
5) Explain the differences between cloud storage, cloud SQL, and cloud BigTable.
- Cloud Storage: A scalable object storage solution for storing and retrieving unstructured data such as photographs and movies.
- Cloud SQL is a managed relational database service that supports SQL databases such as MySQL, PostgreSQL, and SQL Server.
- Cloud BigTable is a fully managed NoSQL database designed for big analytical and operational workloads that require high throughput and low latency, particularly for time-series data and IoT applications.
6) What are the benefits of using persistent disks in GCP?
- High performance: persistent disks provide high IOPS (input/output operations per second) and throughput, making them ideal for demanding applications.
- Durability: Data stored on persistent disks is replicated to multiple locations, ensuring better durability and availability.
- Scalability: Capacity can be increased dynamically without downtime, allowing seamless adaptation to changing storage needs.
- Storage management is simplified through seamless connections with other GCP services like Compute Engine and Kubernetes Engine.
Databases:
7) What managed database services does GCP offer?
- Cloud SQL is a fully managed relational database service that supports MySQL, PostgreSQL, and SQL Server.
- Cloud Spanner: A globally distributed, horizontally scalable, and highly consistent relational database service.
- Firestore is a fully managed NoSQL document database designed for web, mobile, and server development.
8) Explain the concept of sharding in Cloud Spanner.
Sharding in Cloud Spanner is the process of horizontally partitioning data across multiple nodes to spread the workload and increase scalability and performance in a distributed database system.
9) What is the significance of multi-regional replication in cloud SQL?
Sharding in Cloud Spanner is the process of horizontally partitioning data across multiple nodes to spread the workload and increase scalability and performance in a distributed database system.
Security:
10) What is a cloud key management service (KMS), and how is it used?
Cloud Key Management Service (KMS) is a managed service in GCP that stores, manages, and secures cryptographic keys, allowing data encryption at rest and in transit.
11) How do VPC service controls enhance security in GCP?
VPC Service Control establishes a security perimeter around Google Cloud resources, allowing enterprises to design and implement specific access controls, reducing the risk of data leakage and unauthorized access.
12) What is a cloud security scanner, and what does it do?
The Cloud Security Scanner is a Google Cloud Platform (GCP) web security scanner that detects security vulnerabilities in web applications, including cross-site scripting (XSS) and mixed content.
Miscellaneous
13) What services does GCP provide for big data processing?
GCP provides services like Dataproc for managing BigQuery, Apache Spark and Hadoop for data warehousing, Dataflow for stream and batch processing, and an AI platform for machine learning activities.
14) What tools are available in GCP for monitoring and logging?
GCP offers Stackdriver Monitoring, Cloud Trace, Cloud Logging, Cloud Debugger, and Cloud Monitoring for a comprehensive monitoring and logging solution across all GCP services and resources.
15) Explain the purpose of Google Cloud Shell.
- Google Cloud Shell provides a browser-based command-line interface (CLI) for managing GCP resources.
- It provides access to popular programming tools as well as the pre-installed Google Cloud SDK.
- Cloud Shell eliminates the need for local installation, improving stability and accessibility.
Conclusion
In addition to technical knowledge, be prepared to discuss real-world scenarios, your problem-solving approach, and any relevant experience you have with GCP projects or deployments. Practice answering behavioral questions and be prepared to demonstrate your ability to effectively communicate and collaborate with team members.
