AZ-305 Practice Test 2 — 30 Questions

Question 1

A company stores large amounts of log data in Azure Blob Storage. Logs are accessed frequently for the first 30 days, then rarely accessed afterward, but must be retained for 7 years for compliance. The company wants to minimize storage costs. They need to configure automatic data movement and retention policies. Which combination of Azure Blob Storage access tiers and lifecycle management policy should they use?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Use Hot tier for 30 days, then use Archive tier for the remaining period, with a lifecycle rule to delete after 7 years.. It uses the Hot tier for the first 30 days to handle frequent access, then automatically moves data to the Archive tier via a lifecycle management rule to minimize costs for rarely accessed data, and finally deletes the blobs after 7 years to meet compliance retention requirements. The Archive tier offers the lowest storage cost for long-term retention, making it ideal for logs that are rarely accessed after the initial period.

Answer

Use Hot tier for 30 days, then use Cool tier for 7 years, with a lifecycle rule to delete after 7 years.

Answer

Use Cool tier for 30 days, then use Archive tier for 7 years, no lifecycle rule needed.

Answer

Use Archive tier immediately, with a lifecycle rule to delete after 7 years.

Question 2

A company runs a SQL Server database on an Azure VM in West Europe. They need to back up the database daily and retain backups for 7 years for compliance. They also require the ability to restore the database to a secondary Azure region (North Europe) if the primary region fails. They want to minimize operational overhead and costs. Which Azure Backup configuration should they use?

Accepted Answer

A. Azure Backup's built-in cross-region restore (CRR) for Azure VMs allows you to restore SQL Server databases hosted on Azure VMs to a paired secondary region (North Europe) in the event of a disaster, while retaining backups for up to 10 years (covering the 7-year compliance requirement). This configuration minimizes operational overhead by using Azure Backup's native policy-based scheduling and storage management, and it is cost-effective as it uses geo-redundant storage (GRS) for the Recovery Services vault without needing a separate backup infrastructure.

Question 3

A global e-commerce company uses Azure Cosmos DB to store its product catalog. The catalog is read-heavy, with users worldwide expecting consistent reads with a 99th percentile latency under 10 ms. Writes to the catalog are performed by a central admin team in one region. The company needs to minimize write latency and cost while ensuring that users always see the same data within a single session. Which Cosmos DB configuration should the company choose?

Accepted Answer

Single-master write region with Session consistency and multiple read regions. Session consistency provides the required 'read your own writes' guarantee within a single session, which ensures users always see the same data during their session without the latency and cost penalties of Strong consistency. Single-master writes minimize write latency by directing all writes to one region (the central admin team's region), while multiple read regions allow global users to read from the nearest region with sub-10 ms latency. This configuration balances cost, performance, and consistency needs for a read-heavy catalog with centralized writes.

Answer

Single-master write region with Strong consistency and multiple read regions

Answer

Multi-master write with Eventual consistency and all regions enabled for writes

Answer

Multi-master write with Strong consistency and two regions

Question 4

A company runs a mission-critical SQL Server database on an Azure virtual machine using SQL Server Standard Edition. They need a disaster recovery solution that replicates the database to a secondary Azure region with a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour. The solution must support non-disruptive disaster recovery drills. The company cannot modify the SQL Server configuration or use Always On features due to licensing constraints. Which Azure service should they use?

Accepted Answer

Azure Site Recovery. Azure Site Recovery (ASR) replicates the entire VM (including the SQL Server database) to a secondary Azure region, meeting the RPO of 15 minutes and RTO of 1 hour. It supports non-disruptive disaster recovery drills by allowing test failovers in an isolated network without affecting the production environment.
