Connectivity
Question:
“What does VPN stand for in cloud computing?”
Answer:
“Virtual Private Network.”
Question:
“What is object storage in cloud computing?”
Answer:
“A method of storing data as objects with unique identifiers, which can include images, videos, and other file types.”
Question:
“What does HTTPS stand for?”
Answer:
“HyperText Transfer Protocol Secure.”
Question:
“What is Direct Connect in cloud computing?”
Answer:
“A service that allows you to establish a dedicated network connection from your premises to the AWS cloud.”
Question:
“What is the cloud?”
Answer:
“A network of remote servers hosted on the internet, used to store, manage, and process data instead of a local server or personal computer.”
Question:
“What does VPN stand for, and what is its primary use in cloud computing?”
Answer:
“VPN stands for Virtual Private Network. Its primary use is to provide a secure, encrypted connection over the internet, allowing users to access cloud services privately and securely.”
Question:
“How does object storage differ from file storage?”
Answer:
“Object storage is organized by unique identifiers and offers greater scalability, while file storage organizes data in a hierarchical format similar to traditional file systems.”
Question:
“Why is HTTPS important for cloud security?”
Answer:
“It encrypts data during transmission, ensuring the security of data exchanged between the user and the web server.”
Question:
“How does it improve cloud service performance?”
Answer:
“By reducing latency and improving performance for applications that require high bandwidth.”
Question:
“What is the difference between IaaS, PaaS, and SaaS?”
Answer:
PaaS: Platform as a Service – development platform for applications without infrastructure concerns.
SaaS: Software as a Service – software applications delivered online via subscription.
Question:
“How does a VPN help secure data transmission in the cloud?”
Answer:
“It encrypts data sent over the internet, making it secure from eavesdropping.”
Question:
“What is the main difference between object storage and file storage in cloud computing?”
Answer:
“The main difference is that object storage stores data as objects with unique identifiers and metadata, while file storage organizes data into files within a hierarchical structure.”
Question:
“What are the main benefits of using a firewall in cloud computing?”
Answer:
“A firewall controls inbound and outbound network traffic based on predetermined security rules, protecting data and resources from unauthorized access.”
Question:
“How does SDN (Software Defined Networking) benefit cloud environments?
Answer:
“It allows network management to be software-based, making it easier to automate and configure network resources dynamically based on demand.”
Question:
“What are some key benefits of adopting a multi-cloud strategy?”
Answer:
“It offers increased flexibility, redundancy, and minimizes vendor lock-in, allowing companies to choose the best cloud services from different providers based on specific needs.”
Question:
“What are the main types of VPNs used in cloud computing, and what are their key differences?
Answer:
“The main types are Remote Access VPNs (client-to-server connections) and Site-to-Site VPNs (connecting entire networks). The difference is in their scope and use cases, with Remote Access being more for individual users and Site-to-Site for connecting multiple offices or networks.”
Question:
“What are some use cases of object storage in cloud environments?”
Answer:
“It’s commonly used for big data analytics, content delivery, and backups, where the flexibility and scalability are crucial.”
Question:
“What is a firewall and how does it contribute to cloud security?”
Answer:
“A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules, thereby protecting cloud resources from unauthorized access.”
Question:
“What are the challenges of implementing SDN in a hybrid cloud environment?
Answer:
“Integrating different network environments and ensuring seamless communication across private, public, and hybrid cloud setups can be complex due to varying network protocols and policies.”
Question:
“What is the role of a content delivery network (CDN) in cloud computing?”
Answer:
“A CDN stores cached copies of content in multiple locations worldwide to deliver web pages and files faster to users by reducing the distance data must travel.”
Question:
“How does integrating Direct Connect with a VPN enhance network performance and security in hybrid cloud environments?”
Answer:
"Combining Direct Connect with a VPN creates a secure, dedicated link between on-premises networks and the cloud, offering lower latency, higher throughput, and reduced exposure of data over the public internet."
Question:
“How can applying advanced data compression and deduplication techniques in object storage enhance performance and reduce costs?
Answer:
“By compressing and deduplicating data, object storage systems can significantly reduce the amount of storage needed, lowering costs and improving performance by minimizing redundant data.”
Question:
“Explain how cloud-native firewalls differ from traditional firewalls and the implications of their use in cloud environments.”
Answer:
“Cloud-native firewalls are designed specifically for dynamic cloud environments, providing scalability, automation, and the ability to integrate directly into cloud services for fine-grained access control, which is a significant shift from traditional firewalls that are hardware-based and require manual configurations.”
Question:
“How can SD-WAN (Software-Defined Wide Area Network) improve cloud connectivity for enterprises with multiple locations?”
Answer:
“SD-WAN enhances cloud connectivity by dynamically steering traffic across various internet connections and VPNs to optimize performance, reduce costs, and ensure reliable application access across distributed enterprise environments.”
Question:
“How can a multi-cloud strategy be effectively managed to ensure optimal performance and cost efficiency?”
Answer:
"Implementing a multi-cloud strategy requires optimizing workload placement, using centralized management tools for orchestration, and employing cost strategies like reserved instances, spot instances, and cost allocation tags to control expenses across providers."
