AZ-104 Practice Test 5 — 10 Questions

Question 1

A reporting server will run an in-memory analytics application that needs 8 vCPUs and 64 GiB of RAM. The administrator wants a VM family that is a good fit for memory-heavy workloads. Which VM family should be chosen?

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

Accepted Answer

Memory-optimized VM family. Memory-optimized VM families (e.g., Azure E-series) are designed for workloads that require a high memory-to-vCPU ratio, such as in-memory analytics applications. The requirement of 64 GiB of RAM for 8 vCPUs (8:1 ratio) aligns with the memory-optimized profile, which offers up to 8 GiB per vCPU or more, ensuring the application's data fits entirely in RAM for low-latency processing.

Compute-optimized VM family

Answer

Storage-optimized VM family

Question 2

A subnet has a user-defined route for 0.0.0.0/0 that sends all outbound traffic to a virtual appliance. Traffic to 10.20.4.12 must instead go directly to an Azure VPN gateway. What should you configure?

Accepted Answer

Add a more specific UDR for 10.20.4.0/24 that uses the virtual network gateway next hop.. User-Defined Routes (UDRs) use the longest prefix match to determine the next hop. The existing 0.0.0.0/0 route sends all outbound traffic to a virtual appliance, but adding a more specific route for 10.20.4.0/24 with a next hop of the virtual network gateway (VPN gateway) overrides the default route for that subnet, directing traffic to 10.20.4.12 through the VPN gateway.

Answer

Add a network security group rule that allows traffic to 10.20.4.12.

Answer

Increase the priority of the 0.0.0.0/0 route so it is preferred less often.

Answer

Remove the VPN gateway association from the virtual network.

Question 3

A media archive stores large video files that must survive a zone failure in the primary region and also be replicated to a paired region for disaster recovery. The archive team does not want anyone to read from the secondary region during normal operations, and cost should be lower than the read-access variant. Which redundancy option should you configure?

Accepted Answer

GZRS, because it adds zone redundancy and geo-replication without enabling secondary read access.. GZRS (Geo-Zone-Redundant Storage) is correct because it combines zone redundancy (three copies across availability zones in the primary region) with geo-replication to a paired secondary region, but crucially does not enable read access to the secondary region by default. This satisfies the requirement to survive a zone failure, provide disaster recovery to a paired region, and prevent reads from the secondary during normal operations, all at a lower cost than RA-GRS which includes secondary read access.

Answer

LRS, because it keeps copies in a single datacenter and is the lowest-cost option.

Answer

ZRS, because it protects against zone failures but not regional outages.

Answer

RA-GRS, because the read-access copy is needed whenever data is replicated to another region.

Question 4

A storage account must stay online for applications, but administrators have a temporary freeze on configuration changes. Users can still view the account, but attempts to change the access tier, create a container, or update networking all fail. What most likely caused the behavior?

Accepted Answer

A ReadOnly lock was applied to the storage account.. A ReadOnly lock (Azure Resource Manager lock) prevents any modification to the storage account, including changing the access tier, creating containers, or updating networking settings, while still allowing read operations like viewing the account. This matches the described behavior exactly because the lock is applied at the resource scope and blocks all write/delete operations, but does not affect read access.

Answer

A CanNotDelete lock was applied to the storage account.

Answer

An Azure Policy audit assignment was applied to the storage account.

Answer

The account was moved to a different subscription.

Question 5

A reporting application will run on a single Azure VM and needs 8 vCPUs, 64 GiB of RAM, and a temporary local disk for cache. The team wants a size that satisfies the requirement without oversizing memory or paying for an unnecessarily large specialty series. Which two VM sizes meet the requirement best? Select two.

Accepted Answer

E8as_v5. The E8as_v5 is correct because it provides 8 vCPUs and 64 GiB of RAM, matching the requirement exactly, and includes a temporary local disk (SSD) for cache. It belongs to the memory-optimized Esv5 series, which is designed for memory-intensive workloads without oversizing, and the 'as' variant includes local temporary storage.

Answer

D8as_v5

Answer

F8s_v2

Answer

M8ms

Question 6

Order the steps to set up Azure Site Recovery for on-premises to Azure.

Accepted Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Install the Mobility service agent on on-premises machines, Step 4: Enable replication, Step 5: Test failover. The correct sequence for setting up Azure Site Recovery for on-premises to Azure is: create a Recovery Services vault, configure source and target settings, install the Mobility service agent on on-premises machines, enable replication, and then test failover. This order ensures prerequisites are met and replication is active before testing.

Answer

Step 1: Install the Mobility service agent on on-premises machines, Step 2: Create a Recovery Services vault, Step 3: Configure source and target settings, Step 4: Enable replication, Step 5: Test failover

Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Enable replication, Step 4: Install the Mobility service agent on on-premises machines, Step 5: Test failover

Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Install the Mobility service agent on on-premises machines, Step 4: Test failover, Step 5: Enable replication

Question 7

Arrange the steps to create an Azure Storage account with a container and upload a blob.

Accepted Answer

Create storage account → Create container → Set access level → Upload blob → Generate SAS. Create storage account, create container, set access, upload blob, generate SAS.

Answer

Create container → Create storage account → Set access level → Upload blob → Generate SAS

Answer

Create storage account → Upload blob → Create container → Set access level → Generate SAS

Answer

Create storage account → Create container → Upload blob → Set access level → Generate SAS

Question 8

Based on the exhibit, a policy assigned at the subscription denies storage accounts that allow public network access. One existing storage account in RG-Legacy must remain publicly reachable for 30 days while a migration is completed. What should the administrator use?

Accepted Answer

Create a policy exemption for stlegacy01 at the resource scope.. A policy exemption at the resource scope is the correct approach because it allows the administrator to selectively exclude the specific storage account (stlegacy01) from the subscription-level policy that denies public network access. This exemption can be configured with an expiration date of 30 days, ensuring the legacy account remains publicly reachable during the migration while the policy continues to apply to all other resources. Policy exemptions are designed for exactly this scenario—temporary exceptions for compliance or migration needs—without altering the policy definition or assignment.

Answer

Remove the policy assignment from the subscription until the migration finishes.

Answer

Change the policy effect from Deny to Audit.

Answer

Move the legacy storage account to a separate subscription and assign the policy there.

Question 9

A customer-facing service needs to survive a single datacenter outage in a zone-supported region. You do not need cross-region failover, but you do need Azure to spread instances without manual placement errors. Which two deployment choices satisfy that goal? Select two.

Accepted Answer

Place the VMs in different availability zones within the same region.. Availability zones are physically separate datacenters within a region, each with independent power, cooling, and networking. Placing VMs in different zones ensures that a single datacenter outage does not affect all instances, meeting the survivability requirement without manual placement errors. Azure automatically distributes VMs across selected zones, eliminating human error in instance placement.

Answer

Use an availability set and expect it to cover a zone outage.

Answer

Keep all instances in one zone and rely on the load balancer.

Answer

Use a paired region for automatic in-region zone balancing.

Question 10

A contractor must import data into one blob container for six hours. The contractor should not receive the storage account key, and access must be limited to that container only. Which credential should the administrator generate?

Accepted Answer

A user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.. A user delegation SAS is signed with Microsoft Entra credentials (formerly Azure AD) and can be scoped to a specific blob container with a time limit. This meets the requirement of granting the contractor access only to that container for six hours without exposing the storage account key.

Answer

A storage account access key, because it can be copied into the import tool.

Answer

A shared key connection string, because it works with any tool that needs blob access.

Answer

A managed identity token, because the contractor can use it outside Azure directly.
