Exam memorization points
- Name rules: 3-24 characters, lowercase letters and numbers only, globally unique across all of Azure.
- Services in one account: Blob, File, Queue, Table. Enabling a hierarchical namespace turns Blob into Azure Data Lake Storage Gen2.
- Performance: Standard uses magnetic-backed storage; Premium is SSD-backed and is ordered per service (premium block blobs, premium page blobs, premium file shares).
- The account kind to choose on the exam is general-purpose v2 (StorageV2), which supports every access tier and every redundancy option.
- Access tiers for blobs: Hot, Cool, Cold and Archive. Archive objects are offline and need rehydration before they can be read.
- Security posture defaults worth remembering: secure transfer required, minimum TLS 1.2, and blob public access can be disabled account-wide.
Traps & distractors
- Trying to use uppercase letters, hyphens or more than 24 characters in an account name. The name is also the DNS label.
- Expecting to rename or move an account to another region after creation. The name and region are permanent.
- Assuming every region supports every redundancy option. Zone and geo redundancy depend on region availability.
- Mixing up premium page blobs (unmanaged VM disks) with premium block blobs (general blob workloads) and premium file shares - they are separate account kinds.
- Believing the account-level default access tier overrides blob-level tiers. An explicit blob tier always wins.
Suggested lab
Create a hardened general-purpose v2 account
Practise the settings that most often appear as distractors in exam questions.
- 1Create a StorageV2 account with Standard performance, LRS redundancy, hierarchical namespace enabled and blob public access disabled.
- 2Use the portal's name-rule validator: try an uppercase name, then a valid name, and note the error text.
- 3Turn on secure transfer required and set minimum TLS to 1.2.
- 4Add a lifecycle management rule that moves blobs to Cool after 30 days, Archive after 180 days and deletes after 365 days.
- 5Attempt to change the account name and confirm it is read-only after creation.

Critical priority
High-yield and still weak. Study this next.
- Exam importance100% × 30% = 30.0
Learner-agnostic frequency on the real exam (5/5).
- Blueprint weight78% × 25% = 19.4
This topic's domain carries 17.5% of the exam objectives.
- Dependency leverage61% × 20% = 12.2
7 later topics depend on it.
- Current gap100% × 25% = 25.0
Readiness is 0%, so 100% of the topic is still uncovered.
Exam Priority Score = 30% importance + 25% blueprint + 20% dependency + 25% gap. Importance is exam frequency, blueprint is the domain's official exam weight, dependency is how many later topics this one unlocks, and gap is how far you currently are from ready.
