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:

OCP stands for Open Compute Project, which is an initiative to design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing1. OCP is the primary cloud infrastructure platform to develop, test and deliver Nokia's core network applications and business applications, benefiting from its scalability, flexibility, and advanced orchestration capabilities2.

Which one of the following requires a Network Service Descriptor defined in a catalog?

  1. Cloud infrastructure software
  2. Cloud orchestration
  3. Software defined network
  4. Cloud software platform

Answer(s): B

Explanation:

A Network Service Descriptor (NSD) is a template that defines the characteristics and requirements of a network service, such as the number and type of virtual network functions (VNFs), the connectivity and topology between them, the scaling policies, and the service level agreements1. A NSD is defined in a catalog that is managed by the cloud orchestration layer, which is responsible for deploying, monitoring, and controlling the network services across the distributed cloud2. Therefore, cloud orchestration requires a NSD defined in a catalog, while the other options do not.


Reference:

1: Nokia Bell Labs Distributed Cloud Networks, Unit 3: Cloud Resource Planning, Topic: Network Service Descriptor Role 2: Nokia Bell Labs Distributed Cloud Networks, Unit 4:
Operating Your Cloud, Topic: Cloud Orchestration
A Network Service Descriptor (NSD) is an integral part of network function virtualization (NFV) architecture. It describes the composition of network services, including how different network functions are chained or combined to provide a specific service. Cloud orchestration involves the automated management of various cloud computing services and resources, including networking services. It requires a comprehensive description of these services (i.e., NSD) to automate their deployment, scaling, and management effectively. NSD in a catalog would be used to define the parameters and configurations needed for the orchestrated service to be deployed in a cloud environment, making cloud orchestration the most likely context for requiring an NSD.



What are the three key drivers required for video-based service in on-premise cloud? (Select 3)

  1. Convenience
  2. Latency
  3. Privacy
  4. Capacity

Answer(s): B,C,D

Explanation:

Latency, Privacy and Capacity are the three key drivers required for video-based service in on- premise cloud. Latency refers to the delay between the source and the destination of a video stream, which affects the quality of experience for the end-users. Privacy refers to the protection of the video content and the user data from unauthorized access or leakage. Capacity refers to the ability of the network and the cloud to handle the high bandwidth and storage demands of video applications. On- premise cloud is a cloud deployment model where the cloud infrastructure is located within the enterprise premises, and is managed by the enterprise or a third-party service provider. On-premise cloud can offer lower latency, higher privacy and greater capacity for video-based service than public cloud, which is located outside the enterprise premises and is shared by multiple tenants.

Which of the following are benefits of life cycle management?

  1. Life cycle is short.
  2. Life cycle management is only applicable to cloud native.
  3. All life cycle stages are clearly identified.

Answer(s): C

Explanation:

All life cycle stages are clearly identified. Comprehensive Explanation and Reference of
Answer; Life cycle management is the process of managing the Explanationdevelopment, deployment, operation, and decommissioning of cloud applications and services. It involves defining the requirements, design, testing, deployment, monitoring, scaling, updating, and retiring of cloud resources. One of the benefits of life cycle management is that it provides clarity and visibility into the different stages of the cloud service, from inception to termination. This helps to ensure quality, efficiency, security, and reliability of the cloud service, as well as to optimize the use of resources and reduce costs.

Question 62:

  • Correct answer: D (per the page)

  • Note: The explanation text on the page describes option B (use ZDX score and Analyze Score to trigger the Y Engine analysis), indicating a mismatch between the stated answer and the rationale.

  • Key concept: For fast root-cause analysis, leverage telemetry and auto-correlated insights:
- Use the user’s ZDX score for AWS and run Analyze Score to activate the Y Engine, which correlates metrics across network, client, and application to pinpoint the issue quickly.
  • Why the other options are less effective:
- A: Only checks for outages; doesn’t provide actionable root-cause analysis. - C: Deep Trace helps visibility but is manual and time-consuming. - D: Packet capture is invasive and slow; not the quickest path to root cause.

Question 32:

  • Answer: A (2.4GHz)

  • Why: Lower-frequency signals have longer wavelengths and experience less attenuation when passing through walls and obstacles. Higher frequencies (5GHz, 6GHz) are more easily blocked by walls. NFC operates over very short distances and is not meant to penetrate walls. So 2.4 GHz best penetrates physical objects like walls.

Question 3:

  • False is the correct answer (Option B).

Why:
  • In Snowflake, a database is a metadata object that exists within a single Snowflake account. Accounts are isolated—there isn’t one database that lives in multiple accounts.
  • You can access data across accounts via data sharing or database replication, but these create separate database objects in the other accounts (e.g., a database in the consumer account created from a share), not a single shared database across accounts.

So a single database cannot exist in more than one Snowflake account.

Question 1:

  • Correct answer: Edate = sys.argv[1]
  • Why this is correct:
- When a Databricks Job passes parameters to a notebook, those parameters are supplied to the notebook's Python process as command-line arguments. The first argument after the script name is sys.argv[1], so date = sys.argv[1] captures the passed date value directly.
  • How it compares to other options:
- date = spark.conf.get("date") reads from Spark config, not from job parameters. - input() waits for user input at runtime, which isn’t how job parameters are provided. - date = dbutils.notebooks.getParam("date") would work if the notebook were invoked via dbutils.notebook.run with parameters, not

Question 528:

  • Correct answer: NSG flow logs for NSG1 (Option B)

  • Why:
- Traffic Analytics uses NSG flow logs to analyze traffic patterns. You must have NSG flow logs enabled for the NSGs you want to monitor. - An Azure Log Analytics workspace is also required to store and query the traffic data. - Network Watcher must be available in the subscription for traffic analytics to function.
  • What to configure (brief steps):
- Ensure Network Watcher is enabled in the East US region (for the subscription/region). - Enable NSG flow logs on NSG1. - Ensure a Log Analytics workspace exists and is accessible (read/write) so Traffic Analytics can store and query logs.
  • Why other options aren’t correct:
- “Diagnostic settings for VM1” or “Diagnostic settings for NSG1” alone don’t guarantee flow logs are captured and sent to Log Analytics, which Traffic Analytics relies on. - “Insights for VM1” is not how Traffic Analytics collects traffic data.

Question 23:
The correct answer is Domain admin (option B), not Fabric admin.

  • Domain admin provides domain-level management: create domains/subdomains and assign workspaces within those domains, which matches the tasks while following least privilege.
  • Fabric admin is global-level access and is more privileges than needed for this scenario (it would grant broader control across the Fabric environment).

Question 2:
For question 2, the key concept is the Longest Prefix Match. Routers pick the route whose subnet mask is the most specific (largest prefix length) that still matches the destination IP.
From the options:

  • A) 10.10.10.0/28 ? 10.10.10.0–10.10.10.15
  • B) 10.10.13.0/25 ? 10.10.13.0–10.10.13.127
  • C) 10.10.13.144/28 ? 10.10.13.144–10.10.13.159
  • D) 10.10.13.208/29 ? 10.10.13.208–10.10.13.215

The destination Host A’s IP must fall within 10.10.13.208–10.10.13.215 for the /29 to be the best match. Since /29 is the longest prefix among the matching options, Router1 will use 10.10.13.208/29.
Thus, the correct answer is D.

Question 3:

  • Correct answer: Phase 4, Post Accreditation

  • Explanation:
- In DITSCAP, the four phases are: - Phase 1: Definition (concept and requirements) - Phase 2: Verification (design and testing) - Phase 3: Validation (fielding and evaluation) - Phase 4: Post Accreditation (ongoing operations and lifecycle management) - The description—continuing operation of an accredited IT system and addressing changing threats throughout its life cycle—fits the Post Accreditation phase, which covers operations, maintenance, monitoring, and reauthorization as threats and environment evolve.

Question 129:
Correct answer: CNAME

  • A CNAME record creates an alias for a domain, so newapplication.comptia.org will resolve to whatever IP address www.comptia.org resolves to. This ensures both names point to the same resource without duplicating the IP.
  • Why not the others:
- SOA defines authoritative information for a zone. - MX specifies mail exchange servers. - NS designates name servers for a zone.
  • Notes: The alias name (newapplication.comptia.org) should not have other records if you use a CNAME for it, and CNAMEs aren’t used for the zone apex (root) domain. This scenario uses a subdomain, so a CNAME is appropriate.

Question 1:

  • Correct answer: C

  • Why this is best:
- Uses OS Login with IAM, so SSH access is granted via Google accounts rather than distributing per-user SSH keys. - Granting the compute.osAdminLogin role to a Google group gives admin access to all team members in a centralized, auditable way. - Access is auditable: Cloud Audit Logs show who accessed which VM, satisfying the security requirement to determine who accessed a given instance.
  • How it works:
- Enable OS Login on the project/instances (enable-oslogin metadata). - Add the team’s

Question 2:

  • Answer: D. Azure Advisor

  • Why: To view security-related recommendations for resources in the Compute and Apps area (including App Service Web Apps and Functions), you use Azure Advisor. Advisor surfaces personalized best-practice recommendations across resources, including security, and shows which resources are affected and the severity.

  • Why not the others:
- Azure Log Analytics is for ad-hoc querying of telemetry, not for viewing security recommendations. - Azure Event Hubs is for streaming telemetry data, not for security recommendations.
  • Quick tip: In the portal, navigate to Azure Advisor and check the Security recommendations for App Services to see actionable items and affe
