SC-900 Practice Question: Describe the concepts of security, compliance, and identity

This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A user downloads a software update from a company's internal website. The update file is hashed, and the hash value is published on a separate secure page. After downloading, the user computes the hash of the downloaded file and compares it to the published hash. The two values match. Which security concept is primarily demonstrated by this comparison?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Integrity

Hashing is a one-way cryptographic function that produces a fixed-size digest from input data. By comparing the computed hash of the downloaded file to the published hash, the user verifies that the file has not been altered during transit or storage. This directly demonstrates the security concept of integrity, which ensures data has not been tampered with or corrupted.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Confidentiality

    Why it's wrong here

    Confidentiality is about preventing unauthorized access to data. The hash comparison does not protect against disclosure; it checks for alterations.

    When this WOULD be correct

    A user downloads a sensitive document from a company's internal website that is encrypted using HTTPS. The user verifies that the document was not intercepted by checking the TLS certificate. This demonstrates confidentiality because encryption protects the data from being read during transmission.

  • Integrity

    Why this is correct

    Integrity ensures data has not been tampered with. Matching hashes indicates the file is unchanged, confirming its integrity.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Availability

    Why it's wrong here

    Availability ensures that data and systems are accessible when needed. The hash comparison does not address availability.

    When this WOULD be correct

    A question describing a scenario where a company implements redundant servers and load balancing to ensure users can always download updates, even during high traffic or server failures, would demonstrate availability.

  • Authentication

    Why it's wrong here

    Authentication verifies the identity of a user or system. The hash comparison does not verify the identity of the download source; it verifies file integrity.

    When this WOULD be correct

    A user logs in using a password and biometric scan. Which security concept is demonstrated? The answer would be authentication, as it verifies the user's identity.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SC-900 exam frequently reuses these exact scenarios with slightly different constraints.

IntegrityCorrect answer

Why this is correct

Integrity ensures data has not been tampered with. Matching hashes indicates the file is unchanged, confirming its integrity.

ConfidentialityWrong answer — click to see why

Why this is wrong here

The scenario involves verifying that the file has not been altered, which is a matter of data integrity, not confidentiality. Confidentiality is about preventing unauthorized access, not ensuring data remains unchanged.

★ When this WOULD be the correct answer

A user downloads a sensitive document from a company's internal website that is encrypted using HTTPS. The user verifies that the document was not intercepted by checking the TLS certificate. This demonstrates confidentiality because encryption protects the data from being read during transmission.

Why candidates choose this

Candidates may confuse hashing with encryption or think that protecting data from tampering also keeps it secret, but hashing does not conceal the content.

AvailabilityWrong answer — click to see why

Why this is wrong here

Availability ensures that resources are accessible when needed, but comparing hashes verifies that the file has not been altered, which is a matter of integrity, not availability.

★ When this WOULD be the correct answer

A question describing a scenario where a company implements redundant servers and load balancing to ensure users can always download updates, even during high traffic or server failures, would demonstrate availability.

Why candidates choose this

Candidates may confuse availability with the ability to access and verify the file, thinking that the hash comparison confirms the file is 'available' in its original form, rather than recognizing it as an integrity check.

AuthenticationWrong answer — click to see why

Why this is wrong here

Authentication verifies the identity of a user or system, not the integrity of data. Comparing hashes ensures the file hasn't been altered, which is integrity, not authentication.

★ When this WOULD be the correct answer

A user logs in using a password and biometric scan. Which security concept is demonstrated? The answer would be authentication, as it verifies the user's identity.

Why candidates choose this

Candidates may confuse authentication with integrity because both involve verification processes, but authentication verifies identity, while integrity verifies data unchanged.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse integrity with authentication, mistakenly thinking that verifying a hash proves the file's origin (authentication) rather than its unaltered state (integrity).

Detailed technical explanation

How to think about this question

Hash functions like SHA-256 produce a unique digest for each unique input; even a single bit change in the file yields a completely different hash. This property is used in digital signatures and code signing certificates (e.g., Authenticode) to ensure software integrity. In real-world scenarios, attackers may attempt a hash collision, but modern algorithms like SHA-256 are collision-resistant, making this verification reliable.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
