ISTQB Certified Tester - Performance Testing CT-PT Dumps in PDF

Free ISTQB CT-PT Real Questions (page: 2)

CT-PT PDF — 120 Questions

Which of the following is an advantage of using performance monitoring tools?

  1. They can prevent malicious behavior.
  2. They proactively compile metrics from server logs.
  3. They more easily identify and report multi-threading problems.
  4. They can proactively detect denial-of-service (DoS) attacks.

Answer(s): B

Explanation:

Performance monitoring tools collect real-time and historical performance data, particularly from server logs, application metrics, and infrastructure monitoring. This allows testers to analyze performance trends efficiently.

Option A is incorrect because monitoring tools do not prevent malicious behavior but may detect it.

Option C is incorrect since identifying multi-threading issues is typically done through profiling tools rather than performance monitors.

Option D is incorrect as DoS attack detection falls under security testing.


Reference:

ISTQB CT-PT Syllabus, Section 3.2: Performance Monitoring Tools.



Which of the following is usually identified by a performance test?

  1. Resource bottlenecks
  2. Suitability issues
  3. Learnability concerns
  4. Failure to meet accessibility requirements

Answer(s): A

Explanation:

Performance tests primarily identify resource bottlenecks such as CPU saturation, memory leaks, network congestion, and database slowdowns.

Option B (Suitability issues) is a functional requirement concern, not a performance issue.

Option C (Learnability concerns) relates to usability testing, not performance.

Option D (Accessibility requirements) falls under compliance and usability testing, not performance testing.


Reference:

ISTQB CT-PT Syllabus, Section 2.5: Identifying Bottlenecks and Performance Issues.



During which of the principal performance testing activities are the building blocks for larger, more complex tests created?

  1. During test completion
  2. During test planning
  3. During test design
  4. During test implementation

Answer(s): D

Explanation:

Test implementation is the stage where smaller test components are created and assembled into larger test scenarios. This phase includes scripting, test data preparation, and configuring load profiles.

Option A (Test completion) involves analyzing results, not building tests.

Option B (Test planning) focuses on strategies and objectives, not test creation.

Option C (Test design) defines test scenarios and cases, but the actual building happens in implementation.


Reference:

ISTQB CT-PT Syllabus, Section 1.4: Performance Testing Process.



When following the principal performance testing activities, when are resources allocated?

  1. During test planning
  2. During test execution
  3. During test evaluation
  4. During test completion

Answer(s): A

Explanation:

Resource allocation happens during the test planning phase, where hardware, tools, and personnel are assigned to the project. This ensures that performance tests are adequately supported.

Option B (Test execution) is when resources are actually used, not allocated.

Option C (Test evaluation) happens after execution to analyze results.

Option D (Test completion) focuses on documentation and reporting.


Reference:

ISTQB CT-PT Syllabus, Section 1.3: Test Planning in Performance Testing.



Which of the following is a typical performance risk associated with distributed architectures?

  1. A local hard disk that has been de-fragmented
  2. Excess computer memory resources
  3. Unreliable or unpredictable remote servers
  4. Inconsistent Bluetooth connectivity

Answer(s): C

Explanation:

A key risk in distributed systems is unreliable remote servers, which can lead to latency, timeouts, and failures in performance testing.

Option A (Hard disk de-fragmentation) is not a significant risk in distributed systems.

Option B (Excess memory) is a positive factor, not a risk.

Option D (Bluetooth connectivity) is unrelated to distributed system performance.


Reference:

ISTQB CT-PT Syllabus, Section 2.7: Performance Risks in Distributed Systems.



Which of the following is a typical performance risk associated with mobile, browser-based, and embedded real-time architectures?

  1. Slow hard disk speed
  2. Misconfigured host machine
  3. Unexpected loads due to API accessibility
  4. Internet connectivity issues

Answer(s): C

Explanation:

Mobile and browser-based applications often rely on APIs for data retrieval and processing. Unexpected API load can cause latency issues, bottlenecks, and system crashes.

Option A (Hard disk speed) is not a major issue in cloud-based or mobile systems.

Option B (Misconfigured host machine) affects on-premise systems, not mobile/browser-based applications.

Option D (Internet connectivity issues) is a user-side issue, not a system performance risk.


Reference:

ISTQB CT-PT Syllabus, Section 2.7.2: Mobile and Web Performance Risks.



Which of the following is a typical performance risk associated with mainframe architectures?

  1. Inconsistent loads when accessed via APIs
  2. Slow hard disk speed
  3. Misconfigured host machine
  4. Lack of RAM

Answer(s): B

Explanation:

One of the key performance risks in mainframe architectures is slow hard disk speed, which can impact transaction processing, batch jobs, and database access times.

Option A (Inconsistent loads via APIs) is more relevant to distributed or cloud architectures rather than mainframes.

Option C (Misconfigured host machine) is a configuration issue, not a typical performance risk.

Option D (Lack of RAM) is less common in mainframes, which typically use optimized memory management.


Reference:

ISTQB CT-PT Syllabus, Section 2.7.3: Performance Risks in Mainframe Architectures.



You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.

Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

  1. Preferably during each phase in the lifecycle
  2. Preferably at the end of system testing
  3. Preferably during system integration testing
  4. Preferably at the end of unit testing

Answer(s): A

Explanation:

Performance testing should be integrated into every phase of the software lifecycle to ensure that critical performance requirements (such as thrust-to-noise ratio) are met early and continuously validated.

Option B (End of system testing) is too late, as issues may be costly to fix at that stage.

Option C (During system integration testing) is useful but not comprehensive enough.

Option D (At the end of unit testing) is incorrect because unit tests do not assess overall system performance.

Question 34:

  • Question 34 asks: Which role(s) has the capability to create Policies? Choose two.
  • Likely correct roles: Compliance Manager and Compliance admin (A and B). These roles typically have policy governance rights to create and manage policies.
  • Why not the others: Compliance User is usually a limited user, not allowed to create policies. Risk Manager focuses on risks, not policy creation in standard setups.
  • Note on the provided key: The answer shown is “C” (Compliance User), which conflicts with “Choose two.” This is probably a key error. In practice, verify against your instance’s ACLs or official docs.
  • Quick check tip: In ServiceNow, review the ACLs and role permissions for the Policy records to see which roles can create policies.

function of appnav in sdwan

  • AppNav (Application Navigation) is the Cisco SD-WAN feature that provides application-level visibility and control.
  • It maintains a catalog of applications (AppIDs) with attributes (ports/protocols, categories) and classifies traffic accordingly.
  • It allows policy authors to reference apps by name in policies, enabling application-aware routing, QoS, and service chaining based on the app’s requirements.
  • The SD-WAN fabric uses AppNav data to steer traffic along the best path, improving user experience for critical apps while optimizing WAN usage.

Question 5:

  • Correct answer: A. User4 and User1 only

  • Why this is correct:
- The Automatic Enrollment setting in Intune has MDM user scope: GroupA. Only users in GroupA can enroll devices via MDM auto-enrollment. - Device6 will be enrolled via Windows Autopilot and Intune, so enrollment is allowed only for users in GroupA. - Based on the group memberships in the scenario, User4 and User1 are in GroupA, while User2 and User3 are not. Therefore only User4 and User1 can enroll Device6.
  • Quick tip for the exam:
- Remember: MDM user scope determines who can auto-enroll devices; MAM scope controls app protection enrollment. When a new Autopilot device is enrolled, the signing-in user must be in the MDM scope.

Why this is correct

  • Correct answer: C. Extract the hardware ID information of each computer to a CSV file and upload the file from the Microsoft Intune admin center.

  • Why this is correct:
- Windows Autopilot requires devices to be registered by their hardware IDs (hash) before Autopilot can deploy Windows 10 Enterprise. - Collect the hardware IDs from the new Phoenix machines, save them in a CSV, and upload that CSV in the Intune/Windows Autopilot area. This maps each device to an Autopilot deployment profile. - After registration, you can assign Autopilot profiles (Windows 10 Enterprise, etc.). Other options (serial number CSV, generalizing, or Mobility settings) are not the initial Autopilot registration steps.

Question 7:

  • Correct answer: B — A risk score is computed based on the number of remediations needed compared to the industry peer average.

Explanation:
  • Risk360 uses a remediation-based score. It benchmarks how many actions are required to fix issues against peers, giving a relative risk posture.
  • Why not the others:
- A: Not just total risk events by location. - C: Time to mitigate isn’t the primary scoring method. - D: Not a four-stage breach scoring approach.
Note: The page text shows a mismatch (it lists D as the answer), but the study guide describes the remediation-based scoring (B) as the correct concept.

Question 104:

  • Correct answer: D) Multi-Terabyte (TB) Range

  • Brief explanation:
- clustering keys organize data into micro-partitions to improve pruning when queries filter on those columns. - The performance benefit is most significant for very large tables; for small tables the overhead of maintaining clustering outweighs gains. - Therefore, as a best practice, define clustering keys on tables at the TB scale.

Question 62:

  • Correct answer: D (per the page)

  • Note: The explanation text on the page describes option B (use ZDX score and Analyze Score to trigger the Y Engine analysis), indicating a mismatch between the stated answer and the rationale.

  • Key concept: For fast root-cause analysis, leverage telemetry and auto-correlated insights:
- Use the user’s ZDX score for AWS and run Analyze Score to activate the Y Engine, which correlates metrics across network, client, and application to pinpoint the issue quickly.
  • Why the other options are less effective:
- A: Only checks for outages; doesn’t provide actionable root-cause analysis. - C: Deep Trace helps visibility but is manual and time-consuming. - D: Packet capture is invasive and slow; not the quickest path to root cause.

Question 32:

  • Answer: A (2.4GHz)

  • Why: Lower-frequency signals have longer wavelengths and experience less attenuation when passing through walls and obstacles. Higher frequencies (5GHz, 6GHz) are more easily blocked by walls. NFC operates over very short distances and is not meant to penetrate walls. So 2.4 GHz best penetrates physical objects like walls.

Question 3:

  • False is the correct answer (Option B).

Why:
  • In Snowflake, a database is a metadata object that exists within a single Snowflake account. Accounts are isolated—there isn’t one database that lives in multiple accounts.
  • You can access data across accounts via data sharing or database replication, but these create separate database objects in the other accounts (e.g., a database in the consumer account created from a share), not a single shared database across accounts.

So a single database cannot exist in more than one Snowflake account.

Question 1:

  • Correct answer: E — date = sys.argv[1]
  • Why this is correct:
- When a Databricks Job passes parameters to a notebook, those parameters are supplied to the notebook's Python process as command-line arguments. The first argument after the script name is sys.argv[1], so date = sys.argv[1] captures the passed date value directly.
  • How it compares to other options:
- date = spark.conf.get("date") reads from Spark config, not from job parameters. - input() waits for user input at runtime, which isn’t how job parameters are provided. - date = dbutils.notebooks.getParam("date") would work if the notebook were invoked via dbutils.notebook.run with parameters, not

Question 528:

  • Correct answer: NSG flow logs for NSG1 (Option B)

  • Why:
- Traffic Analytics uses NSG flow logs to analyze traffic patterns. You must have NSG flow logs enabled for the NSGs you want to monitor. - An Azure Log Analytics workspace is also required to store and query the traffic data. - Network Watcher must be available in the subscription for traffic analytics to function.
  • What to configure (brief steps):
- Ensure Network Watcher is enabled in the East US region (for the subscription/region). - Enable NSG flow logs on NSG1. - Ensure a Log Analytics workspace exists and is accessible (read/write) so Traffic Analytics can store and query logs.
  • Why other options aren’t correct:
- “Diagnostic settings for VM1” or “Diagnostic settings for NSG1” alone don’t guarantee flow logs are captured and sent to Log Analytics, which Traffic Analytics relies on. - “Insights for VM1” is not how Traffic Analytics collects traffic data.

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.
