NEW QUESTION # 15
Cloud resource management provides which of the following? (Select 2)

• A. Management of the resources quota.
• B. Best effort communication for all tenants.
• C. Resources when available.
• D. The ability to scale resources up and down.

Answer: A,D

Explanation:
Cloud resource management provides management of the resources quota and the ability to scale resources up and down. Resource quota is the limit on the amount of resources that a tenant can use in a cloud environment, such as CPU, memory, storage, network, etc. Resource quota helps to prevent overconsumption of resources by a single tenant and to ensure fair allocation of resources among multiple tenants. The ability to scale resources up and down means that the cloud can dynamically adjust the amount of resources allocated to a tenant based on the demand and availability. Scaling resources up and down helps to optimize the performance and efficiency of the cloud, as well as to reduce the cost and waste of resources.

NEW QUESTION # 17
Which of the following are characteristics of traditional monolithic services. (Select 2)

• A. Low scalability
• B. Very light weight application
• C. Fixed capacity
• D. Very fast deployment

Answer: A,C

Explanation:
The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.

NEW QUESTION # 21
Select the best option below to complete the following sentence. Multi-tenancy network connectivity provides dedicated resources through_____

• A. Dedicated networks
• B. Network Slicing
• C. Configurable Networks
• D. Hardware allocation

Answer: B

Explanation:
Multi-tenancy network connectivity provides dedicated resources through network slicing. Network slicing is a technique that allows operators to create multiple logical networks over a shared physical infrastructure. Each network slice can have its own characteristics, such as bandwidth, latency, security, and quality of service, to meet the specific requirements of different applications and customers. Network slicing enables operators to offer customized and differentiated services to various tenants, such as enterprises, industries, and public sector organizations, while optimizing the utilization of network resources. Network slicing is one of the key features of 5G networks, as it supports the diverse and dynamic use cases of 5G, such as enhanced mobile broadband, massive machine-type communications, and ultra-reliable low-latency communications. Reference: Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks, Unit 4: Operating Your Cloud, Section 4.2: Network Slicing.

NEW QUESTION # 25
What is the sequence of the evolution of Network Functions?

• A. Virtual Network Functions -> Cloud-Native Network Functions -> Physical Network Functions
• B. Physical Network Functions -> Virtual Network Functions -> Cloud-Native Network Functions
• C. Cloud-Native Network Functions -> Physical Network Functions -> Virtual Network Functions
• D. Virtual Network Functions -> Physical Network Functions -> Cloud-Native Network Functions

Answer: B

Explanation:
Physical Network Functions (PNFs) are the traditional network functions that run on dedicated hardware appliances, such as routers, switches, firewalls, etc1. Virtual Network Functions (VNFs) are the network functions that run on virtual machines (VMs) on top of a common hardware platform, such as servers, storage, and network1. Cloud-Native Network Functions (CNFs) are the network functions that run on containers orchestrated by Kubernetes on a cloud infrastructure1. The evolution of Network Functions reflects the trend of moving from hardware-centric to software-centric and cloud-based solutions, which offer more flexibility, scalability, and efficiency12.

NEW QUESTION # 26
Which of the follow are descriptions are correct regarding containers? (Select 2)

• A. A logical space in the host's operating system.
• B. No limited access to resources.
• C. Is a software like a VM.
• D. Is in an isolated environment.

Answer: A,D

Explanation:
A logical space in the host's operating system and B. Is in an isolated environment. A container is a software package that bundles an application and its dependencies, and runs as an isolated process in the host's operating system1. Containers are lightweight, portable, and scalable, and can be deployed on any cloud infrastructure2. Unlike virtual machines (VMs), containers do not need a separate operating system or hypervisor, and share the kernel of the host3. However, containers have limited access to resources, as they are restricted by the host's capabilities and the container runtime4.

NEW QUESTION # 27
Security is crucial for data centers and their users.

• A. False
• B. True

Answer: B

Explanation:
Security is crucial for data centers and their users because data centers store, process, and transmit large amounts of sensitive and valuable data for various organizations and individuals. Data centers face various security threats such as cyberattacks, natural disasters, human errors, power outages, etc. that can compromise the confidentiality, integrity, and availability of the data and the services1. Therefore, data centers need to implement various security measures such as encryption, authentication, authorization, backup, firewall, antivirus, physical security, etc. to protect the data and the users from unauthorized access, data loss, data corruption, service disruption, etc2.

NEW QUESTION # 28
Which of the following best describes the networking concept of "Isolation"?

• A. It allows each tenant to have their own network configuration.
• B. It's the physical network layer.
• C. It restricts traffic within network.
• D. It's the virtual network layer.

Answer: A

Explanation:
Isolation is the networking concept that ensures that each tenant or user of a cloud service has their own network configuration and resources, such as IP addresses, subnets, firewalls, and routers. Isolation provides security, privacy, and performance benefits for the cloud tenants, as they can control and customize their own network settings and avoid interference or conflicts with other tenants. Isolation can be achieved by using different techniques, such as VLANs, VXLANs, VPNs, or network slicing.
Reference:
Nokia Bell Labs 5G Professional Certification - Distributed Cloud Networks | Nokia Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, slide 10 Nokia Bell Labs 5G Certification Program - Courses | Nokia, Distributed Cloud Networks, Unit 2: Cloud Technologies and Features Isolation in networking, particularly in the context of cloud computing, refers to the separation of network traffic for different users or tenant environments within a shared infrastructure. This ensures that each tenant's data and applications remain private and inaccessible to other tenants. Isolation can be achieved through various means, including virtual LANs (VLANs), network virtualization, and software-defined networking (SDN) techniques. The core idea is to provide tenants with the illusion of a private, dedicated network environment, even though the underlying physical infrastructure is shared among multiple tenants. This enables each tenant to have their own network configuration, policies, and management, ensuring security and privacy within a multi-tenant architecture.
