E20-393 PDF — 297 Questions

A system administrator has installed the Unity Connection Utility on a Microsoft Windows host. The Windows host is connected to the same physical subnet as a newly installed Unity storage system. When the utility is run, it does not discover any Unity storage systems.

What should be checked on the host that may be preventing the utility from discovering any Unity storage systems?

  1. Java SE version
  2. Ethernet adapter flow control
  3. Network Access Filter Driver
  4. Host firewall services

Answer(s): A

Explanation:

Unity Connection is dependent on Java for some of the components to work.

Incorrect Answers:
B: Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks.
D: As the traffic is within the same physical subnet a firewall would have no effect.

A Unity 400 system has Data at Rest Encryption licensed and enabled. Which operation(s) must be performed from the Unisphere Settings window to ensure the system is still operational after SP replacements?

  1. Download Audit Log
  2. Download Checksum
  3. Backup Keystore File
  4. Download Audit Log and Checksum

Answer(s): C

Explanation:

The keystore is tied to the storage processors, so care must be taken when performing service operations in order to preserve the encryption keys. In the event that the chassis and both storage processors need to be replaced, both storage processors should not be replaced at the same time. Instead, the chassis replacement should be followed while retaining one SP until the array is back online before replacing the second SP. In the case that storage processors have already been replaced at the same time and the keystore was lost, the keystore may be restored from an external backup.



When a storage resource has a snapshot taken of it, where are writes to the storage resource written?

  1. New space allocated from the storage resource parent pool
  2. New space allocated in 256 MB stripes from FAST Cache
  3. Existing space of the storage resource
  4. Existing space from the Reserves LUN Pool

Answer(s): A



When the LUN Snapshot Attach to Host operation is performed, what does the Unity system optionally do before beginning the attach process?

  1. Creates a snapshot of the LUN
  2. Detaches the host from the snapshots of any other LUN
  3. Creates a copy of the snapshot
  4. Deletes all other existing snapshots of the LUN

Answer(s): B



Which Directory Services can be configured in the Unisphere Settings window?

  1. LDAP
  2. NIS
  3. NDS
  4. Active Directory

Answer(s): A

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.
