Full question →mediummultiple choiceObjective-mapped
A company stores unstructured data such as documents and images in Azure Blob Storage. The data is accessed frequently for the first month, then only rarely for the next year, and after that must be retained for 10 years for compliance. The company wants to minimize storage costs by automatically moving data to the most cost-effective storage tiers. Which Azure Blob Storage feature should they implement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Lifecycle management policies
Azure Blob Storage lifecycle management policies enable automatic transition of blobs to cooler tiers (Cool, Archive) based on age. The policy can move data from Hot to Cool after 30 days, then to Archive after one year, meeting the access pattern and minimizing costs.
B
Distractor review
Azure Data Lake Storage access tiers
Data Lake Storage uses the same Blob Storage tiers but does not automate transitions; lifecycle management would still be needed.
C
Distractor review
Soft delete
Soft delete protects against accidental deletion but does not manage cost tiers.
D
Distractor review
Immutability policies
Immutability policies ensure data cannot be deleted or modified for a set period, but they do not automatically move data to cooler tiers.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Lifecycle management policies — Azure Blob Storage lifecycle management policies enable automatic transition of blobs to cooler tiers (Cool, Archive) based on age. The policy can move data from Hot to Cool after 30 days, then to Archive after one year, meeting the access pattern and minimizing costs. Data Lake Storage uses the same tiers but does not automate transitions. Soft delete and immutability policies do not manage cost tiers.
