A large fishing operation has information on the interval, time, and probabilities of shrimp schools staying beneath their fishing boats. In order to use this information to predict when and where to send their boats, which of the following techniques should be used?

  1. Simulation.
  2. Least squares.
  3. Queuing theory.
  4. Exponential smoothing.

Answer(s): A

Explanation:

Simulation is a technique for experimenting with logical and mathematical models using a computer. Because of the behavior of the many variables involved and the complexity of their interactions, many problems cannot be solved using simple algebraic formulas. The availability of computer spreadsheets makes the construction of simulation models a practical alternative for all entities.



A cost-volume-profit model developed in a dynamic environment determined that the estimated parameters used may vary between limits. Subsequent testing of the model with respect to all possible values of the estimated parameters is termed:

  1. A sensitivity analysis.
  2. Statistical estimation.
  3. Statistical hypothesis testing.
  4. A time-series study.

Answer(s): A

Explanation:

After a problem has been formulated into any mathematical model, it may be subjected to sensitivity analysis. Sensitivity analysis examines how the model's outcomes change as the parameters change.



A company is deciding whether to purchase an automated machine to manufacture one of its products. Expected net cash flows from this decision depend on several factors, interactions among those factors, and the probabilities associated with different levels of those factors. The method that the company should use to evaluate the distribution of net cash flows from this decision and changes in net cash flows resulting from changes in levels of various factors is:

  1. Simulation and sensitivity analysis.
  2. Linear programming.
  3. Correlation analysis.
  4. Differential analysis.

Answer(s): A

Explanation:

Simulation is a technique for experimenting with logical and mathematical models using a computer. Sensitivity analysis examines how the model's outcomes change as the parameters change.



In forecasting purchases of inventory for a firm, all of the following are useful except

  1. Knowledge of the behavior of business cycles.
  2. Internal allocations of costs to different segments of the firm.
  3. Information on the seasonal variations in demand.
  4. Econometric modeling.

Answer(s): B

Explanation:

Internal allocations of costs relate to costs already incurred, that is. to sunk costs. Sunk costs are not relevant to decision making, for example, to forecasting future purchases.



A widely used approach that managers use to recognize uncertainty about individual items and to obtain an immediate financial estimate of the consequences of possible prediction errors is:

  1. Expected value analysis.
  2. Learning curve analysis.
  3. Sensitivity analysis.
  4. Regression analysis.

Answer(s): C

Explanation:

After a problem has been formulated into any mathematical model, it may be subjected to sensitivity analysis. Sensitivity analysis examines how the model's outcomes change as the parameters change.

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

The DP-900 exam can be tricky if you aren't familiar with Microsoft’s specific cloud terminology. I used the practice questions from free-braindumps.com and found them incredibly helpful. The site breaks down core data concepts and Azure services in a way that actually mirrors the real test. As a resutl I passed my exam.
