Huawei H35-210_V2.5 Exam Actual Questions
HCIA-Access V2.5 (Page 16 )

• Correct answer: A
• What this is saying: You need to write a Transact-SQL query that uses REGEXP_SUBSTR to extract the ID from MessageText, and you should apply STRING_ESCAPE(MessageText, 'json') before calling REGEXP_SUBSTR.

• MessageText may contain JSON characters (quotes, backslashes, etc.). Escaping the JSON content first ensures the string you pass to the regex is safe and won’t confuse the regex engine.
• The pattern you apply with REGEXP_SUBSTR would then extract the first substring that matches your ID pattern from the (escaped) text.

• Example (conceptual):

• The question implies REGEXP_SUBSTR is available in this environment; some SQL Server and Fabric contexts don’t expose it natively in all versions. If REGEXP_SUBSTR isn’t available, you’d need an alternative approach (e.g., using built-in regex-like capabilities or CLR/UDFs).
• If you need the ID specifically from the first paragraph, you might first isolate the first paragraph and then apply REGEXP_SUBSTR, or compose a single pattern that anchors to the first paragraph.

• Port 515: LPD/LPR line-printer service
• Port 631: IPP — Internet Printing Protocol
• Port 9100: JetDirect/RAW printing, commonly used by network printers

• Linux machine: Linux could run these services, but the three printer-specific ports strongly indicate a printer.
• Router: Routers may use Telnet and HTTP, but normally would not expose ports 515, 631, and 9100 together.
• Windows machine: Windows can share printers, but this particular service combination is more characteristic of a network printer’s embedded operating system.

• The question asks why some tasks appear locked in the HR Guided Setup Module’s Task view.
• The options are:

• C) They require other tasks to be completed first. In guided setup flows, tasks are usually gated by prerequisites to ensure proper sequencing and data/configuration dependencies. You typically unlock a task only after the necessary preceding tasks are finished.

• A) Elevated roles can restrict access in some contexts, but guided setup tasks are commonly gated by prerequisites rather than solely by role.
• B) Deprecation isn’t the general pattern for “locked” tasks in the guided setup.
• D) A plugin activation could unlock certain features, but the common gating mechanism is task dependencies, not plugin state.

• The page shows the answer as D, but based on how HR Guided Setup usually works, the more accurate reason is typically C (prerequisites). If you’re studying, treat C as the conceptual answer and be aware the listed key may be incorrect. If you want, I can walk through each option in more detail.

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

• Why the other options are not correct:

• Multi-pass wipe: Overwrites the drive’s existing data multiple times, making recovery much more difficult while preserving the drive’s functionality.
• Single-pass wipe: May be sufficient in some modern sanitization standards, but is presented here as less secure than multiple overwrites.
• Degaussing: Uses a strong magnetic field to disrupt data. It can render the drive unusable or unreliable, reducing its resale value.
• Pinning: Is not an appropriate data-sanitization method.

• Answer: D) Out-of-band management

• Why this is correct:

• Why the other options aren’t suitable here:

• The correct answer: C. Tokenization

• Why:

• Why the others are weaker:

• MFA verifies a user’s identity using additional authentication factors, such as a phone prompt or security token.
• It helps prevent unauthorized access even if a password is compromised.
• It does not provide secure storage or encryption of credentials used during automated deployment.

• Enable the owner dimension
• Allocate a standard costing inventory model

• Owner dimension (B): This dimension Lets you track who owns the stock. By enabling the owner dimension, items can be configured as either company owned or consignment (vendor-owned) when you create or edit items. Without enabling this dimension, you can’t designate ownership per item.
• Standard costing inventory model (D): Selecting a costing model determines how item costs are calculated and posted. Standard costing provides a fixed cost per unit, which is commonly used for agreed pricing scenarios like consignment arrangements for easier accounting and valuation. It helps ensure consistent cost treatment across transactions for items that can be owned by the company or on consignment.

• Batch dimension (A): Batch tracking is unrelated to ownership and isn’t required to support company-owned vs. consignment configurations.
• Moving average costing (C): This is an alternative costing method. It’s not required to enable ownership config, and the exam’s expected choice focuses on standard costing for this scenario.

• Amazon S3 — Object storage, not a database.
• Amazon DynamoDB — Fully managed NoSQL key-value and document database.
• Amazon Redshift — Managed data warehouse designed for analytics, not primarily transactional MySQL workloads.

• RPO (Recovery Point Objective) — maximum acceptable data loss, measured in time. It specifies how far back in time you can tolerate data loss. Example: RPO of 2 hours means backups must occur at least every 2 hours.

• ARO (Annualized Rate of Occurrence) — expected frequency of a threat occurring per year. It estimates how often a risk is likely to happen on average (used in risk calculations).

• MTTR (Mean Time To Recover) — average time to recover/restore service after an incident. It includes detection, repair, and restoration time, and helps gauge downtime and alignment with RTO.

• 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.

• 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.

• Short answer: The correct term is Anti-forensics (option D), not “Felony.”

• Why: The actions described—hiding files in slack space, changing file headers, placing suspicious files in executables, and altering metadata—are classic anti-forensics techniques. They’re used to hinder or obscure forensic analysis, not to label the act as a legal category.

• About the options:

• Note: The provided answer key lists B (Felony), which is misleading for this exam objective. The exam typically tests knowledge of forensics concepts, where anti-forensics is the correct category.

• 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.

• Correct answer: D — AWS Migration Hub

• AWS Migration Hub provides a single location to track the progress of application migrations. It offers a centralized dashboard to view migration status across multiple tools and projects.

• AWS Application Discovery Service helps inventory and map on-prem applications and their dependencies, not a single progress tracker.
• AWS Application Migration Service (formerly SMS) performs the actual lift-and-shift migrations, but isn’t the centralized tracker itself.
• AWS Service Catalog manages catalogs of IT services for self-service deployment, not migration progress.

• On-prem you generalize and capture the VM as a VHD.
• Upload the VHD to Azure with Add-AzVhd.
• Register the VHD as an image in Azure with Add-AzImage (or New-AzImage) so it appears as a selectable image.
• Create new VMs from that image (e.g., with New-AzVM -Image ...).

• 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.

• A private IP address on the virtual network
• An associated public IP address

• Geo-redundant storage (GRS) replicates data to a secondary Azure region, but the secondary copy is normally unavailable for read access.
• RA-GRS provides geo-replication and read-only access to the secondary region, satisfying all requirements.
• Zone-redundant storage (ZRS) replicates data across availability zones within the same Azure region, not separate geographic regions.
• Locally redundant storage (LRS) keeps copies within a single datacenter or region and does not provide geographic resiliency.

• 25 — Traditional SMTP server-to-server mail transfer; not normally used for secure client submission.
• 110 — POP3, used to retrieve email and typically unencrypted.
• 143 — IMAP, used to access email and typically unencrypted.

• a) True — To add a field to the form layout, drag the field from the Fields tab to the desired destination on the form. This adds to the form view only, without changing the table definition.
• b) True — To create a new field on the form’s table, drag a data type from the Field Types tab to the form and configure it. This creates a new column on the table and adds the field to the form view.
• c) True — To remove a field from the form layout, hover to enable the action buttons and select Delete. This removes the field from the form view but does not remove it from the table definition.
• d) False — You cannot add a section by dragging from the Field Types tab. Sections are added via the Add Section option (toolbar or right-click menu), not from the Field Types tab.

• Manage multiple organizations from one hierarchy.
• Enterprise-wide policies, including repository visibility, forking, and GitHub Copilot policies.
• Centralized identity and access management, such as SAML SSO, SCIM provisioning, and—where applicable—Enterprise Managed Users.
• Centralized billing and licensing, including organization and Copilot seat management.
• Enterprise audit log, which aggregates activity across organizations.
• Security and compliance oversight, such as organization security visibility and enterprise-wide controls.
• Enterprise support and account management features, depending on the plan.

• Organization: manages its own repositories, teams, members, and local policies.
• Enterprise: governs multiple organizations and can enforce policies across them.

1. Download the updated VPN client configuration package from the Azure VPN gateway.
2. Remove or update the existing VPN client configuration on the Windows 10 workstation.
3. Install the new package and reconnect.

• Developed and maintained independently
• Deployed without changing the entire application
• Scaled separately based on demand
• More resilient when another service has problems

• A: Functional testing is useful, but it is not the main practice described.
• B: Automation helps deployment, but the scenario focuses on architectural decomposition.
• C: Multiple locations improve availability, not application modularity.

• 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.

• Goal: Guests should not use cameras, but company users can.
• Correct configuration: Guest access settings in the Org-wide settings.

• External access: Controls external-domain communication, not guest capabilities inside Teams.
• Teams settings in Org-wide settings: Too generic; doesn’t specifically target guest capabilities.
• Audio & Video in the default Meeting Policy: Would affect everyone assigned to that policy. To meet the requirement without impacting internal users, you’d need separate policies or guest-specific settings; the exam focuses on the guest-access policy.

• Automation handles repetitive tasks, and orchestration coordinates responses across tools (SIEM, SOAR, EDR, etc.).
• This allows the security team to process more events with the same number of people, improving throughput and response times.
• Analysts can focus on more complex tasks like investigation and threat hunting instead of manual triage.

• It increases complexity: automation can reduce complexity when well-implemented; complexity is not the main intended benefit.
• It removes technical debt: automation/OR focuses on current incident response efficiency, not primarily on architectural debt.
• It adds additional guard rails: governance is important but not the core value of automation/orchestration within a SIEM.

• Windows 10 VMs
• Windows Server 2012 or later VMs
• Running VMs—they do not need to be shut down
• Debian 8.2+ VMs, assuming the specific version is supported
• Stopped or deallocated VMs

• The correct answer is Mass Transfer Tool.

• The Mass Transfer Records tool is Salesforce’s built-in way to reassign ownership of existing records in bulk. In this scenario, you need to transfer ownership of the departed rep’s accounts and opportunities to a new rep while keeping the team structure intact.

• Go to Setup > Data Management > Mass Transfer Records.
• Choose the object: Accounts (and then Opportunities, if needed).
• Set “Transfer From” (the leaving rep) and “Transfer To” (the new rep).
• Decide whether to transfer related records as well (e.g., opportunities tied to accounts) and proceed.
• Review and confirm.

• Data Loader / Data Import Wizard are for bulk import/export, not bulk reassigning ownership.
• Dataloader.io is a third-party tool; the built-in Mass Transfer tool is the standard Salesforce method for this task.

• You provision the virtual machine.
• You manage the guest operating system, applications, and configuration.
• Azure manages the physical servers, datacenter, and underlying virtualization infrastructure.

• 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:

• 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.

• The inference container image or built-in algorithm
• The location of model artifacts in Amazon S3
• IAM permissions through the execution role
• Optional environment variables and networking settings

1. Create AWS::SageMaker::Model
