What are the available options to interconnect private Datacenters? (Select 2)

  1. VPN
  2. Backbone
  3. VLAN
  4. VIP

Answer(s): A,B

Explanation:

The available options to interconnect private Datacenters are VPN and Backbone. VPN stands for Virtual Private Network, which is a secure and encrypted connection between two or more networks over the public internet. Backbone is a high-capacity network that connects different data centers across regions or countries. Both VPN and Backbone provide reliable, scalable, and secure data center interconnect (DCI) solutions for private/hybrid clouds.


Reference:

Nokia Cloud DCI offers a more scalable, reliable and secure way to connect data centers in private/hybrid clouds, Nokia business-critical cloud DCI solutions support multiple DCI applications, from real-time business continuity and disaster recovery, to synchronous data replication and cloud backup, Nokia partners with IP Telecom to deliver quantum-safe data center connectivity



Which of the following are properties related to a private cloud? (Select 2)

  1. No OPEX
  2. Mixed with Public Cloud
  3. High CAPEX
  4. Software as a Service
  5. Full Control

Answer(s): C,E

Explanation:

The properties related to a private cloud are high CAPEX and full control. CAPEX stands for capital expenditure, which is the money spent on acquiring or upgrading physical assets such as servers, storage, and network equipment. A private cloud requires high CAPEX because the cloud owner has to invest in building and maintaining the cloud infrastructure. Full control means that the cloud owner has the exclusive authority and responsibility over the cloud resources, security, and operations. A private cloud offers full control because the cloud owner can customize the cloud according to their specific needs and preferences, and can ensure the privacy and compliance of their data and applications.

Which of the following are Software as a Service? (Select 2)

  1. Database-as-a-Service
  2. Infrastructure-as-a-Service
  3. Artificial Intelligence-as-a-Service
  4. Platform -as-a-Service

Answer(s): A,D

Explanation:

Software as a Service (SaaS) is a cloud computing offering that provides users with access to a vendor's cloud-based software. Users do not install applications on their local devices. Instead, the applications reside on a remote cloud network accessed through the web or an API. Within this context, Database-as-a-Service (DBaaS) is considered a form of SaaS, where the service provider manages the database's installation, maintenance, backup, and scaling needs on behalf of the customer. Platform-as-a-Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS can include various software components, including database management systems, and thus can be considered a subset of SaaS.

  1. Open Data Center Platform
  2. Open Compute Project
  3. Operations and Control
  4. Open Circuit Platform

Answer(s): B

Explanation:
