Vmedu Scrum Master Certified Exam Prep
Scrum Master Certified (Page 7 )

• As Beth’s team matures, they gain experience, improve quality practices, and refine what “done” means. The Definition of Done (DoD) becomes clearer and more stringent, helping increments be consistently shippable.
• This aligns with Scrum’s inspect-and-adapt mindset: with each sprint, the team identifies gaps in the DoD and expands it to cover things like testing, integration, and documentation.

• B: Scrum doesn’t require creating a single feasible plan for all backlog items upfront; planning is iterative via Sprint Planning and backlog refinement.
• C: Becoming “projectized” is not a Scrum outcome; Scrum teams remain cross-functional and self-managing, not formal projectized units.
• D: Forming, Storming, Norming, and Performing describe a generic team-development model (Tuckman). It’s not a Scrum-specific maturity expectation and isn’t something Beth can rely on as a standard outcome.

• The scenario highlights failures to incorporate changing customer requirements. In Scrum, work is delivered in short iterations (Sprints), with frequent inspection and adaptation.
• Each sprint delivers an increment and the backlog is updated based on feedback, so changes can be incorporated in subsequent iterations. This keeps the product aligned with the evolving business environment.
• Other options:

• Correct answer: B

• Why: In Scrum, core roles are Scrum Master, Product Owner, and the Development Team. Non-core roles (e.g., stakeholders, domain experts, sponsors) are outside the Scrum Team and provide support, inputs, and constraints but are not continuously involved in Scrum events. They influence the project’s success indirectly through their support and feedback, not as mandatory, ongoing participants in the Scrum process. The other statements mischaracterize non-core roles: they’re not mandatory for success, they do have interest and stake, and they aren’t formally structured to continuously participate in Scrum.

• Free: Doesn’t support the required custom domain and SSL configuration.
• Shared: Doesn’t provide the required SSL support or scalability.
• Basic: Supports multiple instances and SSL, but its storage limit is insufficient for the required 12 GB.
• Standard: Supports:

• To identify the number of errors: select Column quality. It shows the percentage and count of Valid, Error, and Empty values for each column.
• To resolve errors: use the appropriate error transformation:

• Enable screensaver locks: After inactivity, the workstation locks and requires the user to authenticate again. This prevents someone nearby from using an unattended logged-in computer.

• Apply a BIOS password: A BIOS/UEFI password helps prevent unauthorized users from changing boot settings, booting from external media, or bypassing normal startup controls. It adds protection before the operating system loads.

• Defragment the hard drive: Improves drive organization/performance, not access control.
• Enable SSH: Provides remote command-line access and could introduce another access path; it does not restrict local workstation users.
• Disable iCloud integration: Not a general workstation access-control measure.
• Enable the firewall: Protects against network connections, but does not stop an unauthorized person who is physically using the workstation.

• File1 contains the evaluation configuration—for example, evaluators, test data, thresholds, or evaluation parameters.
• The GitHub Actions workflow must reference that file through the evaluation-config input so the action knows which evaluation to run.
• project-endpoint identifies the Microsoft Foundry project, but it does not identify the evaluation definition. It is also typically required, but it does not answer the specific requirement about using File1.

• Deterrent control: The signs warning that people may be filmed can discourage unauthorized activity. They do not physically prevent the activity, but they may influence behavior.
• Detective control: CCTV detects or records activity so security personnel can identify incidents and investigate them later.

• Preventive: Stops an incident from occurring, such as a locked door.
• Corrective: Restores systems after an incident, such as backups.
• Directive: Instructs people what to do, such as security policies or warning instructions.
• Compensating: Provides an alternative control when the preferred control cannot be used.

• Liability accounts (2000–2999) would incorrectly require dimensions, although they should have none.
• Expense accounts (6000–6998) would incorrectly require Customer, which should be optional.
• Account 6999 needs a separate rule because it requires all four dimensions, including Customer.

• 2000–2999: no dimensions
• 4000–4999: Department and Division required; Project and Customer optional
• 6000–6998: Department, Division, and Project required; Customer optional
• 6999: Department, Division, Project, and Customer required

• 25 – Traditional SMTP server-to-server mail transfer; often blocked for client submission and not inherently secure.
• 110 – POP3 for receiving email; unencrypted by default.
• 143 – IMAP for accessing email; unencrypted by default.
• 587 – Authenticated email submission and commonly secured with TLS.

• If the attachment is safe, it is released to the user.
• If malware is detected, the attachment is blocked or removed according to the policy.
• This reduces delivery delays without disabling malware scanning.

• Replace removes the original attachment and replaces it with a text file explaining that it was blocked. It does not primarily optimize delivery time.
• Block and Enable redirect blocks messages with suspicious attachments and can redirect them for review; it does not provide the required faster delivery experience.
• Monitor and Enable redirect is for observation and does not reliably block malicious attachments.

• Outer packet: 10.5.1.1 > 52.165.16.154
• IPv4 protocol field: 41, which indicates IPv6 encapsulation
• Inner packet: IPv6 traffic between 2001:... addresses

• MAC address spoofing: Changes Layer 2 addressing; it does not explain the IPv6-in-IPv4 structure.
• Steganography: Hides data inside files or media, not visibly in a tunneled protocol.
• Broken encryption: No evidence of encryption being cracked.
• On-path sniffing: Involves intercepting traffic, not sending data to an external host.

• Security
• Availability
• Processing integrity
• Confidentiality
• Privacy

• Whether controls are suitably designed, and
• Whether they operated effectively over a period of time

• O dispositivo estar registado no Windows Autopilot;
• A atribuição de Profile1 ao grupo;
• O estado de associação ao Microsoft Entra ID e de inscrição no Intune/MDM.

• Deterrent control: The signs warning people they may be filmed discourage unauthorized or malicious behavior. They may prevent incidents by influencing behavior, but their primary purpose is to deter.
• Detective control: The CCTV system monitors and records activity so security personnel can identify suspicious or unauthorized actions.

• Preventive: Blocks or prevents an incident, such as a lock or access-control system.
• Corrective: Fixes or restores systems after an incident.
• Directive: Tells people what they must do, typically through policies or procedures.
• Compensating: Provides an alternative control when the preferred control cannot be used.

• Case Assignment Rules normalmente são avaliadas quando o caso é criado. Elas podem ser executadas novamente em uma edição somente se o usuário marcar “Assign using active assignment rules”; isso não acontece automaticamente apenas porque o caso foi fechado.
• Portanto, criar uma regra de atribuição não corrige os centenas de casos já fechados e não garante, por si só, que um caso será transferido antes de ser fechado.

• B — Usar uma ferramenta de dados: corrige os registros históricos já existentes, atualizando o Owner.
• D — Criar uma regra de validação: impede que um caso seja fechado enquanto ainda pertence a uma fila. Exemplo conceitual: se Status = Closed e o proprietário for uma fila, bloquear o salvamento.

• Virtual introductions: Team members share their role, experience, location, and working preferences.
• Online icebreakers: Short, informal activities such as “two truths and a lie.”
• Virtual coffee chats: Pair team members for informal, non-project conversations.
• Collaborative problem-solving: The team works together on an online puzzle or scenario.
• Retrospectives: The team discusses what went well, what did not, and how to improve.
• Working-agreement sessions: The team agrees on response times, meeting etiquette, communication channels, and handoffs.
• Recognition sessions: Members acknowledge one another’s contributions.
• Remote workshops: Teams jointly create plans, diagrams, or schedules using collaboration tools.

• A: Knowledge of IT platforms, networks, and methodologies — Useful technical knowledge, but the CISO does not need to be the deepest technical expert.
• C: Regulatory and project management knowledge — Important, but compliance and projects must still support the organization’s broader needs.
• D: Managing people and resources — Essential for execution, but effective management of the wrong security priorities will not produce good results.

• Asynchronous inference is designed for applications that submit individual inference requests, place them in a queue, and retrieve results later. It is useful when requests may take a long time or when traffic is intermittent.
• Batch transform is designed specifically to run inference over an entire large dataset stored in Amazon S3 and produce an output dataset.

• Large dataset/offline processing ? Batch transform
• Large or slow individual requests processed later ? Asynchronous inference

• Driver node: Coordinates Spark jobs and runs in the compute environment.
• Worker node: Executes tasks and processes data.
• Databricks Filesystem (DBFS): Provides storage access for data used by compute resources.

1. Horizontal scaling — Yes

1. Vertical scaling — Yes

1. Scaling can manage costs — Yes

• Horizontal = more or fewer instances
• Vertical = larger or smaller instances

• Defender for Servers is the Defender for Cloud plan that protects Azure VMs and generates security alerts that can be reviewed in Defender for Cloud.
• Azure Diagnostics extension collects guest OS monitoring data, but it does not onboard VMs to Defender for Cloud or provide Defender security alerts.
• Data connectors are used for Sentinel integrations.
• Azure Storage Analytics and workflow automation do not provide VM protection.

• Verifies the sender’s identity using their private key.
• Confirms the transaction was not altered after signing.
• Provides evidence that the signer approved or originated the transaction.

• Digital certificates: Bind an identity to a public key, but do not themselves prove that a specific transaction was signed.
• Encrypted passwords: Protect confidentiality or authentication, but generally do not provide transaction-level nonrepudiation.
• One-time passwords: Authenticate a user for a session or transaction, but usually do not provide durable proof of who authorized the electronic record.

• Standardize which services users can deploy
• Apply governance and access controls
• Manage approved product versions
• Give users self-service access to authorized resources

• AWS Control Tower: Sets up and governs a multi-account AWS environment.
• AWS Cloud Map: Provides service discovery for applications.
• AWS Clean Rooms: Enables privacy-preserving collaboration on data analysis.

• Early units show relatively large time savings.
• Later units still take less time, but the reduction becomes progressively smaller.
• The curve therefore becomes flatter as production approaches 256 units.

• B: The reduction is not constant; learning normally diminishes over time.
• C: Time does not reduce at an increasing rate.
• D: A steady state may eventually be reached, but the question concerns the first 255 units while learning is still occurring.

• Least privilege: Limits users to only the access necessary for their job.
• Background checks: Help identify potentially risky individuals before employment.
• Separation of duties: Ensures that one person cannot complete a sensitive process alone, reducing fraud and abuse.

• The CSV contains the external users’ email addresses.
• The bulk invitation feature supports inviting many guest users in one operation.
• Each invited user becomes a guest account in contoso.com.

• When the MVP will be defined — the MVP should already be understood sufficiently when assessing the business case.
• What the MVP is — useful information, but not the key requirement tested here.
• That the MVP is the same as project viability — incorrect. The MVP helps test viability; it is not identical to viability itself.

• Technical platform interfaces: Important for integration and interoperability, but they should support—not drive—the architecture.
• Scalability of the network: Valuable as the organization grows, but a scalable solution is ineffective if it does not meet business or security needs.
• Development methodologies: Relevant to implementation, but they do not define the organization’s fundamental security requirements.

1. Deployment type: Standard

1. Version update policy: Opt out of automatic model version upgrades

• netstat -tuln can show listening TCP ports.
• If the web service is not listening, or is bound only to 127.0.0.1, remote browsers cannot connect even though the server responds to ping.

• traceroute: Tests the path to the server, but ping already confirms basic reachability.
• tcpdump: Useful for detailed packet analysis, but it is more appropriate after checking whether a service is listening.
• arp: Helps troubleshoot local IP-to-MAC resolution, not an application-layer web connection.

• The Speech resource subscription key
• The Azure region
• Optional endpoint and speech settings

python 
speech_config = speechsdk.SpeechConfig( 
    subscription=key, 
    region=region 
)

• SpeechSynthesizer converts text to speech.
• It uses a SpeechConfig, but it does not configure the service connection itself.

• AudioConfig: Defines audio input or output sources.
• AudioOutputConfig: Defines where synthesized audio should be sent.
• SpeechConfig: Configures the Azure Speech service connection.

1. Yes — Microsoft Foundry provides a secure, governed environment for building and managing generative AI applications and agents. It brings together models, data, tools, evaluation, deployment, and monitoring.

1. Yes — Foundry is designed for enterprise workloads and supports scaling AI applications as usage grows. Scalability comes from the underlying Azure services and managed infrastructure.

1. Yes — Foundry can be used in solutions involving image recognition and computer vision. Applications can use vision-capable models and Azure AI vision capabilities for tasks such as image analysis, object detection, and OCR.

• Create a CodeCommit repository in the secondary Region.
• Use CodeBuild to run a Git mirror operation from the primary repository to the secondary repository.
• Use EventBridge to detect relevant repository events, such as a pull request being merged.
• Invoke a Lambda function, which starts the CodeBuild project.

• B: Amazon S3 is object storage, not a Git repository that developers can use as a CodeCommit remote.
• C: CodeArtifact is intended for packages and artifacts, not source-code repository mirroring.
• D: An AWS Cloud9 environment is not an appropriate automated replication mechanism and would require manual or persistent infrastructure management.

• Layer 1: Check cables, power, and link lights.
• Layer 2: Check switching, VLANs, and MAC learning.
• Layer 3: Check IP addressing, routing, and gateways.
• Higher layers: Check services, applications, and user settings.

• Create a plan of action: Decide how to implement the fix.
• Implement the solution: Apply the selected fix.
• Verify functionality: Confirm the problem is resolved and systems work normally.

DAX 
Sales % of Total = 
DIVIDE( 
    [Total Sales], 
    CALCULATE( 
        [Total Sales], 
        ALLSELECTED(Products) 
    ) 
)

DAX 
Total Sales = 
SUM(Sales[SalesAmount])

Why ALLSELECTED is required

• The numerator, [Total Sales], is evaluated for the current product.
• ALLSELECTED(Products) removes the current product’s visual filter when calculating the denominator.
• It preserves filters applied at the report, page, or slicer level.

Why not ALL(Products)?

DAX 
CALCULATE([Total Sales], ALL(Products))

• 25 — Traditional SMTP server-to-server mail delivery; often restricted and not the usual client submission port.
• 110 — POP3, used for retrieving email; normally unencrypted.
• 143 — IMAP, used for retrieving and synchronizing email; normally unencrypted.

Correct reasoning

• Create storage5 as a General-purpose v2 (StorageV2) account.
• Configure Blob object replication from storage5 to an existing compatible storage account.
• The destination must support object replication—typically another StorageV2 or premium block blob account.
• Blob versioning must be enabled on both accounts.
• Blob change feed must be enabled on the source account.
• The accounts must meet Azure’s object-replication requirements, including being in supported regions and having compatible configuration.

• JDBC
• SnowSQL
• Snowflake Web Interface (UI)
• ODBC
• Python connector

• IRR assumes that interim cash flows can be reinvested at the project’s own IRR. This may be unrealistic, especially when the IRR is very high.
• MIRR assumes reinvestment at a specified rate, usually the company’s cost of capital or another realistic reinvestment rate.

• B: MIRR does not specifically favour projects with long payback periods.
• C: MIRR and IRR can rank competing projects differently.
• D: MIRR is not always higher than IRR; it may be higher or lower depending on the cash flows and reinvestment rate.

• Vulnerability scanner: Finds known technical weaknesses in systems or applications, but does not provide complete supply-chain visibility.
• Penetration test: Simulates attacks against defined targets; it is narrower than a full supply-chain analysis.
• SCAP: A set of standards and protocols for automated security configuration and vulnerability assessment, not a comprehensive supply-chain mapping tool.

1. Install a Cassandra-compatible ODBC driver.
2. Configure a data source name (DSN), if required.
3. In Power BI Desktop, select Get Data > ODBC.
4. Choose the configured DSN and connect.

• Microsoft SQL Server database: Connects to SQL Server, not Cassandra.
• OLE DB: Requires a compatible OLE DB provider; this is not the standard choice for Cassandra in Power BI.
• OData: Requires Cassandra data to be exposed through an OData service, which is not the normal direct connection method.

• An Adj-SID does not necessarily need manual configuration.
• It can often be dynamically allocated by the router, although manual configuration may also be possible.
• The adjacency information is advertised through the IGP, such as IS-IS or OSPF.

• It is identified by an Adj-SID.
• It represents a particular adjacency of a node.
• Its meaning is generally local to the advertising node; unlike a Node-SID, it is not a globally reusable instruction across the network.

• Controlar o fluxo de dados entre S3 e SageMaker;
• Aplicar regras de segurança por meio da VPC;
• Reduzir a exposição dos dados;
• Permitir acesso privado ao bucket do S3.

• Amazon Inspector: avalia vulnerabilidades, mas não gerencia o fluxo de dados.
• Amazon Macie: ajuda a descobrir e proteger dados sensíveis no S3, mas não cria a conexão com o SageMaker.
• S3 Glacier Deep Archive: é uma classe de armazenamento para arquivamento, não uma solução de conectividade.

1. The specific table — for example, incident
2. The parent table — for example, task
3. The wildcard table — *, which applies broadly

• Virus signatures: Associated primarily with antivirus or antimalware tools.
• Security agent deployment: Usually handled by endpoint-management or endpoint-detection-and-response tools.
• Vulnerability scanning: Performed by vulnerability-management or vulnerability-scanning tools.

• Relationship cardinality:

• Filter direction:

• Active versus inactive relationships: only active relationships automatically propagate filters.
• Blank or unmatched values: a fact-table value without a matching dimension row can create the model’s blank/unknown member.
• Uniqueness: the “one” side must contain unique values; duplicate keys generally belong on the “many” side.

Step 1: Calculate the rights issue price

Step 2: Calculate the number of new shares

Step 3: Calculate the value after the issue and project

• Rights issue proceeds: $21.6m
• Project NPV: $5m

Step 4: Calculate the theoretical ex-rights price
