NEW QUESTION # 47
Which IBM Cloud service provides virtual servers and bare metal servers with SAN-like iSCSI storage?
- A. IBM File Storage Service
- B. IBM Backup Storage Service
- C. IBM Object Storage Service
- D. IBM Block Storage Service
Answer: D
Explanation:
Block storage is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned.
When data is moved to block storage, the underlying SAN technology breaks the data into separate, uniform-sized pieces, or blocks. Each block will be given a unique identifier. The SAN will then place those blocks onto the physical storage, distributing them across several disks, often making multiple copies.
When a user or application requests data from a block storage system, the underlying SAN technology reassembles the data blocks and presents the data to the user or application.
Block storage decouples data from user environments. It allows data to be spread and duplicated across multiple storage devices, enabling faster retrieval and higher resilience to disk failures.
Benefits:
Provides the lowest latency: Block storage provides the lowest latency for network-based storage versus local disk drives in the server, Provide IOPS up to 48,000 IOPS.
High performing: Block storage is highly available and independent of the clients that access it. It remains available and durable regardless of client outages.
High redundancy: Network-based block storage is considered to have a higher level of redundancy compared to local disk storage.
Endurance and Performance tiers: Block storage has two tiers from which to choose. Volumes can be created from 20 GB to 12 TB in size.
Eight authorized hosts: Block storage allows eight authorized hosts (can request up to 64) to connect via the multipath IO (MPIO) iSCSI connection.
Snapshots: Block storage allows point-in-time non-disruptive "snapshots," which can be replicated to a cross-regional data center as a duplicate volume.
Custom costs: Block storage allows monthly and hourly billing cycles.
Data-at-rest encryption: Block storage offers provider-managed encryption-at-rest. Note: Customer-managed encryption is not supported by IBM Classic Storage; however, customer-managed encryption keys can be stored Use Cases :
As you have learned, block storage has a high performance and is easily updatable. Therefore, many organizations use it for transactional databases.
Because of its high performance and reliability, block storage is a common solution for storing emails.
Block storage suitable for low latency workloads where consistently high speeds required.
NEW QUESTION # 48
Which cloud storage have poor performance when data needs to be shared ?
- A. Object Storage
- B. File Storage
- C. Direct Attached
- D. Block Storage
Answer: C
Explanation:
Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories. The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases : Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.
NEW QUESTION # 49
Which of the followings are characteristics of serverless architecture? Except
- A. Describes a finer grade deployment model where applications are bundled as one or more functions
- B. Refers to building and running applications that do not require server management
- C. Enables a simpler, more cost-effective way to build and operate cloud-native applications
- D. Provides automatic upgrades, patching, and deployment
Answer: D
Explanation:
Serverless computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto-scalable so it can handle extremely active traffic periods.
Serverless computing does-not means there are no physical servers utilized, of course there are servers, but we don't have to manage them, in background cloud provider manage (provisioning, scheduling, scaling, patching and more) for us, this gives developers more time to develop and optimize their front-end application code and business logic. And with serverless, customers never pay for idle capacity. They pay only for the resources required to run their applications, and only when those applications are running.
Serverless is a polyglot environment, enabling developers to code in any language or framework - Java, Python, node.js - with which they're comfortable. Because serverless scales up and down on demand in response to workload, it offers significant cost savings for spiky workloads. But it does not offer the same savings for workloads characterized by predictable, steady or long-running processes; in these cases, a traditional server environment might be simpler and more cost-effective.
Serverless Implementations differ across service providers, and capabilities vary, including supported runtimes, authentication, scaling and monitoring.
Serverless architectures are well-suited for event-driven, IOT and stream-processing workloads most notably open-source Apache Kafka event streaming platform.
Benefits:
- Pay only for the time for our code will run.
- Developer don't have to take care of servers or infrastructure, it maintains by cloud provider, so they can focus more on development and business logic.
- API Management & Integrated event sources.
- Serverless scales up and down on demand in response to workload

- A. Greater visibility into security and access control
- B. Greater elasticity and scalability
- C. Resource optimization, and cost savings
- D. Security and regulatory compliance
- E. Full control over hardware and software choices
Answer: D,E
Explanation:
Hybrid Cloud combines public cloud, private cloud and on-premises infrastructure to create a single, flexible, cost-optimal IT infrastructure. Hybrid Cloud model best suits where security and regulatory compliance required. Use Cases : Security and regulatory compliance: We can reserve sensitive data and highly regulated workloads behind-the firewall in private cloud and can use more economical public cloud resources for less-sensitive workloads and data. Resource optimization, and cost savings: We can manage predictable capacity workload on private cloud and can migrate unpredictable workloads to public cloud to scale up quickly and automatically. Cloud Scaling : A business has on-premise infrastructure that can handle a certain amount of user load. The hybrid allows them to scale up in response to a larger load then automatically de-provision resources when they no longer need them. Multicloud: Composite cloud are applications that are spread across multiple cloud environments. If a business has on-premise architecture that allows them to run three components of their app but the system gets bogged down in busier times, such as holidays, they take advantage of the multicloud architecture by composing their application across multiple cloud environments. In-Correct Answers - Full control over hardware and software choices : In Private cloud, customer have full control over IT infrastructure, They are free to purchase the hardware and software as per their choice. They can customize(configure) servers and software as needed. - Greater visibility into security and access control, In Private Cloud, all workloads run behind the customers' own firewall. - Greater elasticity and scalability: With public cloud, a customer can add capacity in response to unexpended surges in traffic, without purchasing and installing new hardware. [Exam Tips] : You can expect few questions from here in your exam, so before appearing for exam, you should be aware of use cases of private, public and hybrid cloud.

NEW QUESTION # 64
Which database is a document-based database?
- A. etcd
- B. Db2
- C. MongoDB
- D. Redis
- E. PostgreSQL
Answer: C
Explanation:
Correct Answer : MongoDB is an open source, non-relational database management system that uses flexible documents to process and store various forms of data. A NoSQL solution, MongoDB provides an elastic data model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for applications and services. MongoDB uses documents or collections of documents as its basic unit of data. Formatted as JSON objects, these documents can store various types of data and be distributed across multiple systems. MongoDB offers a few capabilities that make it stand out from other database management systems, including load balancing, ad hoc database queries, and multi-language support. In-Correct Answers Redis (for REmote DIctionary Server) is an open-source, in-memory, NoSQL key-value store that is used primarily as an application cache or quick-response database. Redis supports multiple data structures, built-in Lua scripting, multiple levels of on-disk persistence, and high availability. While Redis is an in-memory database store, MongoDB is known as an on-disk document store. Although both solutions are built for different purposes, they are often used together to maximize the speed and efficiency of a NoSQL database. PostgreSQL, commonly pronounced "Post-GRES," is an open-source database that has a strong reputation for its reliability, flexibility, and support of open technical standards. PostgreSQL provides the ability to restore databases to a specific moment in time because it maintains a write-ahead log that logs every database change. PostgreSQL features built-in support for multiple procedural languages. etcd is an open-source, distributed key-value store used to hold and manage the critical information that distributed systems need to keep running. etcd's performance is heavily dependent upon storage disk speed, so it's highly recommended to use SSDs in etcd environments. Db2 is a relational database with enterprise-grade performance. It provides multizone support allowing it to be run in a highly-available configuration. Note : Cloudant is also a document database that uses JSON files to store and index documents. Its serverless design allows for easy scaling based on need.
