EMC E20-555 Exam Dumps - Real Questions, Study Tips, and More

The E20-555 certification is designed for professionals who specialize in the architecture and design of Isilon storage solutions. This certification validates the expertise of technology architects who are responsible for planning, designing, and implementing complex storage environments within enterprise infrastructures. Organizations that rely on EMC storage technology often require their architects to hold this credential to ensure that their data management strategies align with industry best practices. By utilizing our E20-555 exam dumps, candidates can prepare effectively for the rigorous assessment required to earn this professional designation. This certification serves as a benchmark for technical proficiency, demonstrating that an individual possesses the necessary skills to handle sophisticated storage design challenges.

What the E20-555 Exam Covers

The E20-555 exam covers several critical domains that are essential for any architect working with Isilon systems. These domains ensure that candidates have a comprehensive understanding of both the hardware infrastructure and the software management tools required to maintain high performance. By mastering these areas, architects can confidently approach the design and implementation phases of their projects.

  • Isilon Infrastructure - This domain focuses on the physical and logical components of the Isilon cluster, including nodes, networking, and the OneFS operating system architecture.
  • Isilon Management - This area covers the administrative tasks and tools necessary to monitor, configure, and maintain Isilon clusters for optimal performance and availability.
  • Solution Design Process - This section evaluates the ability to gather requirements, assess business needs, and translate them into a functional and scalable Isilon storage solution.
  • Workload Analysis Tools - This domain involves the practical application of diagnostic and analytical software to assess data patterns and performance requirements for specific storage workloads.

The Solution Design Process is often considered one of the most technically demanding areas of the exam because it requires candidates to synthesize multiple technical requirements into a cohesive architecture. Unlike simple configuration tasks, this domain tests your ability to make trade-offs and design decisions that directly impact the long-term success of a storage deployment. Candidates should dedicate extra study time to this section by reviewing E20-555 exam questions that present complex, scenario-based challenges. Understanding how to map business needs to technical specifications is a core competency that differentiates a successful architect from a novice.

When you use our E20-555 dumps, you are accessing a resource built by the community for the community.

Maintaining the accuracy of our study materials is a continuous process that involves active participation from our user base. Unlike a static E20-555 dumps PDF that might become outdated as soon as the vendor updates the exam, our platform allows for real-time adjustments based on user feedback. Candidates who have recently taken the exam often discuss specific answer choices and flag any content that no longer aligns with the current version of the test. This collaborative effort keeps our E20-555 exam dumps current, ensuring that you are always studying the most accurate information available. By relying on this collective knowledge, you can avoid the pitfalls of using obsolete study guides that do not reflect the modern testing environment.

What Makes These E20-555 Dumps Different

What sets our platform apart from other resources is the depth of support provided with every question in our E20-555 dumps.

When you engage with the material deeply, you develop the critical thinking skills necessary to handle variations of questions that you might see on the real exam. Our E20-555 exam dumps are designed to foster this type of deep learning by providing clear, logical explanations for every question. Candidates who take the time to read these explanations perform significantly better because they can apply their knowledge to new and unfamiliar situations. This is the primary advantage of using our community-verified resources over traditional, static study methods.

How to Use These E20-555 Exam Dumps Effectively

To use these E20-555 exam dumps effectively, you should adopt a systematic approach that prioritizes understanding over speed. Start by reviewing the topics you find most challenging and use the AI Tutor explanations to clarify any concepts that remain unclear. It is also highly recommended to supplement your study with hands-on practice in a sandbox or lab environment, as this reinforces the theoretical knowledge found in the dumps. By creating a consistent study schedule and working through the E20-555 real questions in small, manageable blocks, you can track your progress and identify areas that require further review. This structured method ensures that you are fully prepared for the demands of the certification exam.

A common mistake candidates make is attempting to memorize the E20-555 dumps without actually engaging with the technical content. This strategy often fails because the exam is designed to test your ability to apply knowledge to real-world scenarios, not just your ability to recall specific facts. To avoid this, focus on the logic behind each answer and try to explain the concept to yourself or a peer. Additionally, be mindful of your time management during your practice sessions, as this will help you build the stamina needed for the actual exam day. By avoiding the trap of passive memorization, you will be much better equipped to handle the complexities of the E20-555 certification.

What to Expect on E20-555 Exam Day

On the day of your E20-555 exam, you should expect a professional testing environment that is typically administered through a secure platform like Pearson VUE. The exam format generally consists of a series of multiple-choice questions, though you may also encounter scenario-based questions that require you to analyze complex storage design problems.

Which statement is true about using default environment variables? The environment variables can be read in workflows using the ENV: variable_name syntax. The environment variables created should be prefixed with GITHUB_ to ensure they can be accessed in workflows The environment variables can be set in the defaults: sections of the workflow The GITHUB_WORKSPACE environment variable should be used to access files from within the runner.
Correct answer: The statement "The GITHUB_WORKSPACE environment variable should be used to access files from within the runner." is true.
Why the others are false:

  • ENV: variable_name syntax is not how you read env vars in workflows. Use ${{ env.VARIABLE }} in expressions or $VARIABLE in a shell.
  • Environment variables don’t need a GITHUB_ prefix. Custom vars can have any name; GITHUB_ is only for built-in, predefined vars.
  • defaults: cannot set environment variables. It configures defaults for run steps (like shell or working-directory), not env vars.

Extra tip:
  • GITHUB_WORKSPACE (or ${{ github.workspace }}) is the root path on the runner where the repository is checked out. Use it to access files, e.g., $GITHUB_WORKSPACE/... or ${{ github.workspace }}/....

As an administrator for this subscription, you have been tasked with recommending a solution that prohibits users from copying corporate information from managed applications installed on unmanaged devices. Which of the following should you recommend? Windows Virtual Desktop. Microsoft Intune. Windows AutoPilot. Azure AD Application Proxy.

  • Microsoft Intune

Reason: Intune can enforce app protection policies (MAM) on managed apps, even on unmanaged devices, to prevent data leakage (e.g., restricting copy/paste, saving to non-approved apps, etc.). The other options don’t address data protection within apps on unmanaged devices.

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.

  • 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.
