Linux Foundation Certified System Administrator LFCS Exam Questions in PDF

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 1:

• 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

Question 5:

• Correct answer: A. User4 and User1 only

• Why this is correct:

• Quick tip for the exam:

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:

Question 7:

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

• 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:

Question 104:

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

• Brief explanation:

Q23: Fabric Admin is correct. Because Domain admin cannot create domains. Only Fabric Admin can among the given options. Q51: Wrapping @pipeline.parameter.param1 inside {} will return a string. But question requires the expression to return Int, so correct answer should be @pipeline.parameter.param1 (no {})

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:

• Why the other options are less effective:

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).

• 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.

Question 1:

• Correct answer: E — date = sys.argv[1]
• Why this is correct:

• How it compares to other options:

Question 528:

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

• Why:

• What to configure (brief steps):

• Why other options aren’t correct:

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

Question 3:

• Correct answer: Phase 4, Post Accreditation

• Explanation:

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:

• 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:

• How it works:

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:

• Quick tip: In the portal, navigate to Azure Advisor and check the Security recommendations for App Services to see actionable items and affe

This is very interesting

Are these the same questions you have to pay for in ExamTopics?

For Question 7 - while the answer description indicates the correct answer, the option no. mentioned is incorrect. Nice and Comprehensive. Thankyou

This is very good and accurate. Explanation is very helpful even thou some are not 100% right but good enough to pass.

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.

interesting

Passed this exam 2 days ago. These questions are in the exam. You are safe to use them.

Helpful to test your preparedness before giving exam
