Answers
1) The following statements is TRUE about the content(s) of SLA:
(a) It describes about the responsibilities of the provider and the consumer
- A service Level Agreement or SLA is a contract between a service provider and a consumer which documents the particular aspects of the service (quality, availability, and responsibilities) that are agreed upon between the service provider and the service consumer.
Therefore the correct answer is only (a)
2) Direct SLA and Negotiable SLA are two types of SLA - False
SLA is of three types. They are customer, internal and multilevel SLA.
Therefore direct SLA and Negotiable SLA are not the two types of SLA. The answer is (b) False
3) The properties of the cloud from an economic point of view are the following:
(a) Utility pricing
(b) On-demand resources
(d) Online connectivity
The major features of cloud computing from an economic point of view are as follows:
- Utility pricing refers to the pay-as-you-go model of the pricing provided by cloud service providers, which makes cloud services economic
- On-demand access to resources provides scalability and flexibility to the cloud service.
- Online connectivity reduces the entry barrier for users to access the cloud service, as it can be accessed online, by anyone
Therefore, the correct answers are (a), (b), and (d)
4) Penalty Cost varies with the integration of (d) D(t) - R(t)
When you own your resource, you pay a penalty if your resource does not match the demand in real-time. Either you pay a penalty for not using a resource or you pay a penalty for missing a service delivery; the choice is yours. Therefore, if D(t) is instantaneous demand at time t and R(t) is instantaneous resources at time t, then Penalty cost is proportional to
The correct answer is (d)
5) The following are the types of Parallel Database Architectures:
(a) Shared memory
(b) Shared nothing
(c) Shared disk
Parallel database systems are gaining traction as a solution for large, expanding databases that require great performance and scalability. Multiprocessing is used in a parallel database system to boost performance. Shared memory, shared disc, and shared-nothing are the three basic forms of parallel database architectures.
- Multiple processors are connected via an intercommunication channel or communication bus to global shared memory in a shared memory system
- A shared disc system has many processors, each of which has local memory and is connected to numerous discs via an intercommunication channel
- In the shared-nothing system, each CPU has its local memory and disc
Therefore, the correct answers are (a), (b), and (c)
6) Teradata is not a traditional transaction processing database
A transaction processing system, or TPS, is a system that captures and processes the comprehensive data required to update data on an organization's core operations. Examples of traditional transaction processing databases include Oracle, Netezza, DB2, etc.
Teradata is a popular RDBMS. It is mainly used for building large-scale data warehousing applications.
Therefore, the correct answer is (d)
7) The component of OpenStack responsible for spawning, scheduling, and decommissioning virtual machines on demand is (b) Nova
- Neutron is an OpenStack project to provide network-connectivity-as-a-service between interface devices managed by other open stack services
- Nova of OpenStack is responsible for spawning, scheduling, and decommissioning virtual machines on demand
- Swift of OpenStack offers cloud storage software so that you can store and retrieve lots of data with a simple API
- Cinder of OpenStack is responsible for providing persistent block storage to running instances
Therefore, the correct option is (b)
8) The component of OpenStack responsible for providing persistent block storage to running instances is (d) Cinder
Refer previous answer
Therefore, the correct option is (d)
9) WSLA is a formal XML-schema-based language to express SLA
WSLAs are agreements between a service provider and a consumer that outline the parties' responsibilities. This is primarily a service provider's commitment to offering a service by agreed-upon guarantees for IT-level service criteria (such as availability, response time, and throughput) for Web Services.
Therefore, the correct answer is (b) WSLA
Answer:- 1. (a) It describes about the responsibilities of the provider and the customer.
2. (a) True
3. (a) Utility pricing OR (d) Online connectivity
4. (c) D(t) / R(t)
5. (a) Shared memory
6. (d) Teradata
7. (b) Nova
8. (c) Swift
9. (b) WSLA
SLA is Service Level Agreement. It is a commitment between a service provider and a client. It is a particular aspect of the service, such as the quality, the availability, the responsibilities are agreed between the service provider and the service user.
It is defined as:-
1. The metrics are used to measure the level of service provided to customer.
2. The Remedies or the penalties results from the failure to meet the promised service level of the expectations.
The most common component of an SLA is that the services should be provided to the customer as it is agreed in the contract. It is a critical component of the technology vendor contract. For an example, the Internet service provider will commonly include service level agreements within the given terms of their contracts with the customers to define the level of service being sold in plain language terms. Usually, SLAs are the agreements between companies and external suppliers, but they might also be between two departments within the company.
