Huawei H12-425 Exam Actual Questions
HCIP-Data Center Facility Deployment V1.0 (Page 10 )

• Import mode loads the data into the Power BI model. Visuals query the in-memory model, which generally provides faster calculation and rendering than DirectQuery.
• Import mode also minimizes online processing because report interactions do not send queries back to the dataflow or SQL Server.
• A daily refresh can load data through the previous day, satisfying the freshness requirement without unnecessary hourly processing.

• DirectQuery keeps querying the data source or dataflow during report use, increasing online processing and potentially slowing visuals.
• Adding a gateway enables connectivity for on-premises sources, but it does not remove the performance disadvantages of DirectQuery.
• An hourly Power Automate refresh is unnecessary when the requirement is only data through the previous day and creates additional processing overhead.

• Answer: C (192.168.0.1-192.168.0.99, 192.168.0.101-192.168.0.254)

• Why: The interface is 192.168.0.100/24, so DHCP pools must be within the 192.168.0.0/24 subnet and cannot include the router’s IP (192.168.0.100), the network address (192.168.0.0), or the broadcast (192.168.0.255). Option C provides two ranges that exclude those addresses.

• Why the other options are invalid:

• To get min/max per column, you need column profiling. That’s provided by enabling the column profile.
• To actually see those min/max values, you should show the column profile in the details pane, and you also need the details pane itself enabled so you can view it.

• Enable column profile (B)
• Show column profile in details pane (C)
• Enable details pane (E)

• Show column value distribution (D) shows distribution shape but isn’t required to get min/max.
• Show column quality details (D) deals with data quality metrics, not min/max.

• Question 142: Security governance is MOST associated with which IT infrastructure component? Network / Application / Platform / Process
• Answer: D. Process

• Security governance is about how decisions are made, accountability, and oversight to ensure security objectives align with business goals. These are implemented through governance processes (policy development, risk management, assurance, monitoring, escalation, etc.).
• The other options (Network, Application, Platform) are concrete IT components; governance affects them, but it’s exercised primarily through the processes that govern how those components are managed and controlled.

• In governance-related questions, focus on the decision-making, accountability, and control processes rather than the underlying technology components.

Why B works

• AWS KMS keys are Regional resources. A normal customer managed key in Region A cannot be used directly in Region B.
• A customer managed multi-Region KMS key (MRK) has related key replicas in both Regions. The replicas share key material and key ID, although each has a Regional ARN.
• With client-side encryption, the application encrypts the data before storing it in S3. Cross-Region replication then copies already-encrypted objects, so S3 does not need to decrypt and re-encrypt them with a different Regional key.

Why the other choices are weaker

• A and C: SSE-S3 uses Amazon-managed S3 keys, not the required customer managed KMS key.
• D: SSE-KMS can work only if the solution creates and configures the appropriate KMS key or multi-Region key replica in each Region. As written, it says to create a customer managed KMS key in each Region, which implies separate keys—not the same KMS key. Replication also requires additional KMS permissions and destination encryption configuration.

• Cutover: The old system is replaced immediately. It may be fast, but any failure can cause significant disruption.
• Phased: The system is introduced in stages, which reduces implementation risk but may prolong the transition.
• Pilot: The system is first deployed to a limited group or location. This is useful for testing but does not necessarily minimize downtime for the entire organization.

• Risk tolerance describes the organization’s overall risk appetite, not the risks themselves.
• Risk transfer is a treatment option (e.g., insurance), not a documentation artifact.
• Risk analysis assesses likelihood and impact but doesn’t establish ownership or thresholds in a formal register.

• Goal: Identify the host that originated the infection, then label each remaining host as infected or clean based on log evidence.

• Logs to review (across hosts and firewall):

• How to identify the origin:

• How to classify other hosts:

• Quick tip: use the Reset All option if you want to re-run the scenario and practice again.

• Pull: Downloads changes from the central repository and updates the local repository.
• Push: Sends local commits to the central repository.
• Commit: Records local changes in the repository’s history.
• Merge: Combines changes from different branches.
• Clone: Creates a new local copy of a repository.

• Why: Crisis management relies on established, repeatable procedures for responding to an incident (activation of the crisis team, escalation paths, communications, containment actions). This ensures a coordinated, timely, and auditable response.

• Why not the others:

• En Cisco SD-Access, el fabric overlay se extiende hasta lo inalámbrico; los APs son nodos de borde del fabric y su tráfico queda dentro del overlay.
• El cliente inalámbrico genera tráfico que viaja por el overlay, pero no es un componente del fabric en sí.
• El WLC es principalmente una herramienta de gestión y control, no forma parte del overlay; el underlay es el transporte físico.

• IaaS provides virtualized infrastructure, including VMs, disks, and networking. You manage the guest operating system and software installed on the VM.
• PaaS provides a managed platform for deploying applications without managing the underlying VMs or operating systems. Examples include Azure App Service and Azure Functions.

• Problème: le système d’alertes signale des fluctuations tout en manquant les activités qui restent anormalement constantes sur une période longue. Il faut donc un scénario qui capte les anomalies qui se maintiennent dans le temps plutôt que les pics ponctuels.
• Peer: permet de comparer un client à ses pairs; utile pour repérer des écarts relatifs, mais ne cible pas nécessairement les motifs d’anomalie persistante sur plusieurs périodes.
• Revenus mapping: relie les transactions à des sources ou flux de revenus; utile pour l’analyse des fonds, mais pas directement pour détecter une anomalie longue durée.
• Below-the-line: conçu pour détecter des activités qui passent en dessous des seuils habituels ou qui demeurent anormales sur une longue période, comblant ainsi la faiblesse des alertes à long terme.

• Answer: D) Shadow IT

• Why: Shadow IT is when employees use unsanctioned tools or bypass IT controls (like the VPN) to access services, often without IT oversight. It’s an internal behavior, not an external attacker’s activity.

• Not these:

• Quick note: This creates risk due to lack of visibility and control. Mitigations include a defined approved-tools list, enforcing VPN usage, device management, and continuous monitoring.

• Domeny tworza restrykcjony razem z typem. Wykorzystujesz je w kolumnach, aby miec spójna walidacje danych w wielu miejscach.

• latwo wymuszaja wspólne reguly dla wielu kolumn/naglówków,
• zmiana regul w jednym miejscu (domena) automatycznie wplywa na wszystkie kolumny ja uzywajace.

• Correct answer: C. AWS CloudFormation

• Why: CloudFormation lets you define infrastructure as code via templates (JSON or YAML). You can create a single template that describes multiple AWS resources and reuse it to deploy consistent stacks across environments. Templates can be parameterized and stored for repeated deployments. Other options (Marketplace, AMI, OpsWorks) don’t provide reusable deployment templates in the same way.

• Define the contractor’s deliverables, responsibilities, acceptance criteria, and deadlines.
• Agree on a reporting cadence to monitor progress.
• Allow the local company to use its expertise and manage its own work.

• A: “Under the supervision of the project manager” suggests excessive direct control and is less empowering.
• B: Micromanaging prevents the contractor from functioning independently and is inefficient.
• D: Deploying the contractor’s staff under the PM’s supervision creates a staffing/control arrangement rather than empowering the contracted company.

• Two instances: Free/Shared do not provide the production-level multi-instance hosting you need. Basic/Standard support more than one instance, with Standard specifically meeting the scale requirement.
• SSL support: SSL (custom domain TLS) isn’t available on the Free tier and isn’t a driver for cost on paid tiers—but you’ll need a paid tier to map a custom domain (miami.weyland.com) and use SSL.
• Storage: Your site needs 12 GB. Free/Shared have very limited storage; Basic tier storage is typically smaller than what you need, while Standard provides substantially more storage capacity.
• Cost: Among the tiers that meet all requirements (two instances, SSL, sufficient storage), Standard is the lowest-cost option that satisfies them.

• On-Demand: You pay by the hour with no long-term commitment. This is ideal for workloads that are infrequent or have highly variable usage. Since this job runs only 24 hours once per year, you pay only for those 24 hours, with no wasted upfront or long-term payments.
• Reserved Instances: Require a 1- or 3-year commitment and pay for capacity whether you use it or not. For a workload that runs just 24 hours a year, you’d be paying for most of the term unused, making it far less cost-efficient.
• Spot Instances: Can be interrupted whenever AWS needs capacity, which is unacceptable for an uninterruptible workload.
• Dedicated Instances: Generally more expensive and aimed at licensing or compliance requirements; not needed for this use case.

• A — SCIM synchronizes changes to user attributes from the identity provider to GitHub.
• B — SCIM deactivates GitHub accounts when users are removed or deactivated in the identity provider.
• D — SCIM automates user provisioning when new users are added to the identity provider.

• C: SCIM does not delete organization repositories.
• E: SCIM does not generate REST API authentication tokens.
• F: SCIM handles identity lifecycle management, not repository permission configuration based on roles.

• A) MTU mismatch: OSPF neighbors must exchange Hello packets with a compatible MTU. If MTUs differ, the neighbor conversation fails and the adjacency cannot become Full.

• B) Incorrect subnet mask: Routers must be in the same IP subnet on the connected link to form a neighbor relationship. A subnet mismatch prevents Hello packets from being considered valid on the same network.

• D) Area ID not the same: Neighbors must share the same Area ID. A mismatch stops adjacency from forming beyond the 2-Way state.

• E) Different metric set on each end of the link: Cost differences do not prevent OSPF adjacency; they affect routing decisions, not neighbor formation.
• F) Router ID not defined: OSPF can auto-choose a router ID; an undefined ID is not a prerequisite for adjacency to reach Full.

• What the scenario tests: How monitoring paths on a Universal Forwarder (UF) behave when you deploy an app via the Deployment Server.
• How monitoring is configured: Log paths to monitor are defined in inputs.conf (within apps/local on the UF). Splunk on the UF merges inputs from all apps and local config.
• Key point: Deploying a new app that adds a monitor for a log file does not typically remove existing monitors. The UF will continue monitoring any previously configured paths and will add the new ones from the deployed app.

• Correct answer: C) /var/log/maillog and /var/log/messages.

• Azure Resource Manager templates: Use ARM templates to define the VM infrastructure and baseline configuration as code. This ensures all Windows Server 2016 VMs are created with a uniform setup, minimizing manual configuration.

• PowerShell Desired State Configuration (DSC) extension for Windows: DSC enforces a defined state across all servers and can automatically remediate drift. This keeps the VMs in the desired configuration with minimal ongoing admin effort.

• Answer: C — 192.168.0.0/25 as summary and 192.168.0.0/27 for each floor

• Why:

• Sustainability is not a CAF perspective (it's not one of the CAF perspectives).
• Performance efficiency and Reliability are pillars of the AWS Well-Architected Framework, not CAF.

• Answer: C – netstat -an

• netstat -an lists all active connections and listening ports with numeric addresses, without resolving names. This lets you spot DoS patterns such as a flood of connections to a specific port or many connections from a single or few IPs.
• The other options don’t help as directly:

• Windows: netstat -an and look for numerous ESTABLISHED connections to a service or many SYNs to a port.
• Filter by port, e.g., netstat -an | findstr :80, or on Linux: ss -tunap | grep ':80'.

• Netstat provides a snapshot. DoS detection often benefits from continuous monitoring, flow data, and IDS/IPS logs.

• Why: The data is unlabeled, so you can’t train a model with known input-output pairs. Unsupervised learning discovers structure in the data by grouping similar customers into clusters or tiers without labels.
• What it does: Clustering and segmentation (e.g., k-means, hierarchical clustering, DBSCAN, Gaussian mixtures) to form meaningful groups.
• Why the other options aren’t as suitable:

• Answer: Data enhancement.

• Why: Augmenting gold-layer tables with an additional dataset is enriching or enhancing the existing data to support the ad-hoc analysis. The other options don’t capture the idea of adding external data to improve the dataset (ad-hoc improvements = tweaks, last-mile dashboarding = building dashboards, last-mile ETL = ETL steps at the end of the pipeline). In practice, this is often also called data enrichment.

• The correct permission is Manage Sandboxes (the official Salesforce name; the option in the list is written as “Manage Sandbox,” which is effectively the same idea but the canonical name uses the plural).
• Why: Sandboxes are a lifecycle feature. Only users with the explicit Manage Sandboxes permission can perform create, delete, refresh, or activate actions.
• Why the other options aren’t correct:

• A. Configure prompt modifications to enforce tone, disclaimers, and refusal behavior at the system level.

• D. Configure Power Platform DLP policies to restrict unauthorized data connectors.

• B: Manual topic-by-topic disclaimer edits are specifically discouraged.
• C: Channel settings do not replace agent-level Responsible AI controls.
• E: Publishing before enabling safety filters violates the stated deployment sequence. Responsible AI filters should be enabled before publication, not afterward.

• Co to znaczy: transakcje zachowuja sie tak, jakby byly wykonywane jeden po drugim. Dzieki temu nie ma brudnych odczytów, niepowtarzalnych odczytów ani phantom reads.

• Implementacja: PostgreSQL uzywa SSI (Serializable Snapshot Isolation). W praktyce oznacza to, ze jesli wykryje konflikt miedzy transakcjami, jedna z nich zostanie zakonczona bledem “serialization failure” i trzeba ja ponowic.

• Zalózmy tabele orders(customer_id int, amount int).

• Transakcja T1:

• Transakcja T2, równoczesnie:

• T1 ponownie wykonuje to zapytanie:

• C — Schema.describeSObjects(new String[]{myObject})[0].fields.getMap()

• D — Schema.getGlobalDescribe().get(myObject).getDescribe().fields.getMap()

• A: sObjectType is not used this way, and fieldSet() is not the appropriate method for retrieving all fields.
• B: mySObject.myObject is not valid dynamic Apex syntax.

• Answer:

• Why:

• Why the other centers aren’t the right fit here:

• Ensure that only users who manage the production environment sign in to the Azure portal from a hybrid Entra-joined device and authenticate with MFA.

• Use Microsoft Entra ID Protection (Identity Protection) to enforce MFA enrollment:

• Update the existing Capolicy1 (a Conditional Access policy):

• Identity Protection MFA registration policy ensures users are enrolled in MFA (Box 1 choice).
• CA policy Capolicy1 with aGrant control of “Require MFA” enforces MFA during sign-in (Box 2 choice).
• Both work together with the hybrid-joined device requirement to satisfy the authentication/authorization rules.

• Apply the MFA registration policy to the production-management users.
• Apply the MFA grant to Capolicy1 for those same users/groups.

• User1 can sign in because the account is cloud-only. It does not depend on the on-premises domain.
• User3 can sign in because the account uses Password Hash Synchronization (PHS). Azure AD has a synchronized password hash and can validate the sign-in even when connectivity to on-premises Active Directory is unavailable.
• User2 cannot sign in because the account relies on Pass-through Authentication (PTA). PTA sends the authentication request to an on-premises PTA agent, which must contact a domain controller. With the internet connection from on-premises lost, that validation cannot occur.

• The correct AAA mapping (per Cisco objectives) is:

• Why the given options aren’t fully correct:

• Quick takeaway: when you configure AAA, you should conceptually map them as:

• Example commands (to reinforce concepts):

• Answer: S3 Inventory report.

• Why: The S3 Inventory report provides a scheduled listing of objects within a bucket, including metadata about each object. When you configure it to include object tagging, you can see tags for each object, and the object keys (which reflect prefixes) and bucket scope are captured in the report. This makes it suitable for auditing and tracking “tags, buckets, and prefixes” across S3 objects.

• What the other options do (not suitable for this purpose):

• Tip: If you need tags in the report, enable the inventory option to include object tagging in the configuration.

• S3 Versioning stores all versions of an object. If an object is overwritten or deleted, you can recover the previous version using its version ID.
• This protects against accidental deletion or overwriting because the original data remains accessible as an older version.
• How to enable:

• Practical notes:

• S3 Lifecycle rules: automate moving/expiring data, not specifically protection against deletion.
• S3 bucket policies: control access but don’t inherently preserve previous data.
• S3 server-side encryption: protects data at rest, not against deletion/overwrite.

• Transact-SQL (T-SQL) is used to query relational data in Azure SQL Database, not telemetry data from monitoring services.
• To analyze monitoring data from Azure SQL Database Intelligent Insights and Azure Application Insights, you should use the Kusto Query Language (KQL) in Azure Monitor Logs/Log Analytics (and in Application Insights Analytics).
• Using KQL lets you query telemetry tables such as requests, dependencies, pageViews, and customEvents (from App Insights) and any integrated monitoring data you’ve ingested into Log Analytics.

• Ensure Intelligent Insights and Application Insights data is available in a Log Analytics workspace or accessible via Application Insights Analytics.
• Go to Azure Monitor > Logs (or Application Insights > Analytics) and write KQL queries, e.g.:

• Self-signed certificate: Causes a certificate warning, not incorrect IP resolution.
• Nameserver record: A DNS record problem would typically affect multiple users, not just one.
• IP helper: Relays DHCP or other broadcast traffic between networks; it does not control website name resolution.

• Answer: B — Improve employee training and awareness

• Why this is correct:

• Why the other options are less effective here:

• Quick practical note:

• Alice is co-resident on the same physical host and exploits shared hardware (the processor cache) to infer secrets. This is the classic definition of a side-channel attack—information leakage through implementation details (like timing or cache behavior) rather than by breaking a protocol or injecting code.

• Observing cache timing or access patterns to deduce cryptographic keys or plaintext data from the victim VM.

• Man-in-the-cloud attack: targets cloud trust/auth, not local hardware sharing.
• SQL injection: exploits input to run SQL commands, not a VM/caching vector.
• Service hijacking: takes control of a service, not about covert data leakage via shared hardware.

• Notice phrases like “shared hardware resources,” “co-resident,” or “cache”—these indicate a side-channel vector.

powershell 
Get-AzureVM -ServiceName <service-name> -Name <vm-name> | 
  Set-AzureStaticVNetIP -IPAddress <private-ip> | 
  Update-AzureVM

• New-AzureRMVMConfig configures VM settings but does not itself assign the static IP.
• Set-AzureSubnet is not the appropriate cmdlet for assigning a VM’s private IP.
• The Azure portal option mentioned in the question was not the intended method for this older deployment model.
• Changing settings in Windows Network and Sharing Center is incorrect because Azure assigns the IP through the VM’s virtual network interface; manually configuring it inside the guest can cause conflicts.

• Failed login attempts
• The account being targeted
• The source user or system
• Time and frequency of attempts

• Two-factor authentication: Helps prevent unauthorized access, but does not primarily detect the employee’s attempts.
• Firewall: Controls network traffic; it generally does not monitor individual login attempts.
• Intrusion prevention system (IPS): Can detect certain network attacks, but this scenario is best addressed through authentication and audit logging.

• Each statement is evaluated as True (Yes) or False (No) independently.
• Key Azure facts to recall:

• Azure Files is an example of infrastructure as a service (IaaS). No. Azure Files is a managed storage service, typically considered PaaS (Storage as a Service), not IaaS.
• A DNS server that runs on an Azure virtual machine is an example of platform as a service (PaaS). No. Running a DNS server on a VM is IaaS because you manage the OS and DNS software.
• Microsoft Intune is an example of software as a service (SaaS). Yes. Intune is a cloud-based, fully managed service you use over the Internet.

• The Scrum Guide specifies four required events: Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective. These events enable transparency, inspection, and adaptation.
• The other items listed are not mandatory under Scrum:

• 6-phone boxes: 6x
• 8-phone boxes: 8x

• Correct answer: enable SLAAC on an interface (C)

• Why the other options are not correct:
