Which of the following is a fundamental component of a cloud data platform?
Local desktop storage
Storage layer
Mobile application interface
On-premise data center only
The storage layer is a core component of cloud data platforms, providing scalable and durable data persistence. It enables other services like processing and analytics to access and manage data efficiently.
What is the primary difference between batch ingestion and stream ingestion?
Batch ingestion only handles structured data, while streaming handles unstructured data
Batch processes data in intervals, while streaming processes data in real-time
Batch ingestion uses ETL tools, while streaming uses ELT tools
Batch ingestion requires manual uploads, while streaming is always automated
Batch ingestion groups data and processes it at scheduled intervals, whereas streaming ingestion captures and processes data continuously in real time. This distinction affects latency and system design requirements.
Which security principle ensures that users have only the minimum permissions needed to perform their tasks?
Defense in depth
Segregation of duties
Single sign-on
Principle of least privilege
The principle of least privilege restricts user permissions to the minimum necessary, reducing the risk of unauthorized access. It is fundamental to securing cloud data platforms.
What type of storage is optimized for storing large volumes of raw, unstructured data for analytics?
Transactional database
Data warehouse
Data lake
In-memory cache
A data lake is designed to store large volumes of raw, unstructured, or semi-structured data. It provides flexibility for analytics and machine learning workloads.
Which cloud feature automatically adjusts resource capacity based on current demand?
High availability
Load balancing
Auto-scaling
Failover
Auto-scaling dynamically adjusts compute resources in response to traffic patterns, ensuring applications run efficiently at varying loads. It helps optimize cost and performance.
In an ELT workflow, at which point are data transformations applied?
During data extraction from the source
During data archiving
After loading into the target data warehouse
Before extracting data from source systems
In ELT workflows, raw data is first loaded into the target system and then transformed in place. This leverages the scalable processing capabilities of cloud data warehouses for complex transformations.
Which AWS service is specifically designed for real-time data streaming ingestion?
Amazon Simple Queue Service
Amazon S3
AWS Glue
Amazon Kinesis Data Streams
Amazon Kinesis Data Streams is designed for real-time ingestion of streaming data at scale. It enables applications to process and analyze data as it arrives with low latency.
Encryption at rest refers to encryption applied to data when it is ________.
stored on disk or in object storage
transmitted over the network
processed in memory
indexed in a database
Encryption at rest means that data is encrypted when stored on disk or in object storage. This protects data from unauthorized access if storage media is compromised.
Which technique involves dividing a large dataset into smaller, manageable segments to improve query performance?
Data masking
Data partitioning
Data replication
Data encryption
Data partitioning divides a large dataset into smaller segments based on key or range criteria. This improves query performance by limiting the amount of data scanned during queries.
In a distributed database, what does sharding refer to?
Backing up data to cold storage
Combining small files into larger ones
Encrypting data at the application layer
Splitting data across multiple nodes based on a key
Sharding splits a database horizontally across multiple nodes using a shard key. It enables horizontal scalability by distributing data and query load.
What is the primary purpose of a data catalog in cloud data governance?
Managing metadata for data discovery
Encrypting data at rest
Orchestrating data pipelines
Monitoring resource usage
A data catalog manages metadata about data assets, facilitating data discovery and lineage tracking. It is crucial for governance by providing context and documentation for datasets.
Which cloud pricing model offers a discount in exchange for a long-term usage commitment?
On-demand instances
Reserved instances
Spot instances
Pay-as-you-go
Reserved instances offer a discounted rate in exchange for committing to a specified usage term. This model reduces costs for predictable, steady-state workloads.
Which big data processing framework is optimized for in-memory distributed computing?
Apache Hadoop MapReduce
Apache Pig
Apache Spark
Apache Hive
Apache Spark is optimized for in-memory distributed computing, which accelerates iterative algorithms and interactive queries. It reduces disk I/O compared to traditional MapReduce.
Which cloud service model provides managed platforms and abstracts away underlying infrastructure?
IaaS
SaaS
CaaS
PaaS
Platform as a Service (PaaS) provides a managed environment for deploying applications without managing underlying infrastructure. It abstracts server management and scaling tasks.
Which technique uses a temporary, high-speed storage layer to reduce read latency?
Sharding
Partitioning
Caching
Archiving
Caching uses a temporary high-speed storage layer, such as in-memory caches, to serve repeated reads quickly. This reduces latency and alleviates load on primary data stores.
In a Lambda architecture for big data, which layer handles low-latency streaming data processing?
Serving layer
Master layer
Speed layer
Batch layer
In Lambda architecture, the speed layer processes streaming data with low latency for real-time views. It complements the batch layer by handling recent data that has not yet been processed in batch.
What is a common tradeoff when choosing database sharding over replication?
Stronger consistency guarantees
Reduced write latency
Increased complexity of cross-shard queries
Simplified backup processes
Sharding adds complexity to queries that span multiple shards, often requiring distributed joins or application-side aggregation. While it improves scalability, it complicates data management.
Which practice is essential for enforcing cost governance in cloud data platforms?
Encrypting all data at rest
Applying consistent resource tagging
Disabling auto-scaling
Using only on-demand resources
Consistent resource tagging allows organizations to attribute costs accurately and enforce policies. It is fundamental for cost tracking, reporting, and governance.
Which consistency model allows replicas to temporarily diverge for higher availability?
Causal consistency
Eventual consistency
Read-your-writes consistency
Strong consistency
Eventual consistency allows replicas to temporarily hold different data states to improve availability and partition tolerance. Over time, all replicas will converge to a consistent state.
For a read-heavy analytics workload, which storage strategy is generally most efficient?
Columnar data store
In-memory cache only
Row-based transactional database
Key-value store
Columnar data stores organize data by columns, which is efficient for read-heavy analytics workloads due to reduced I/O per query. They improve performance for aggregation and filtering operations.
