AZ-104 Practice Test 11 — 15 Questions

Question 1

A company has 15 branch Windows file servers that must show the same shared drive content. Users should keep working during short WAN outages, and local servers should cache frequently used files. Which Azure feature should you deploy?

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

Accepted Answer

Azure File Sync, because it synchronizes on-premises file servers with an Azure file share and supports cloud tiering.. Azure File Sync is the correct choice because it synchronizes on-premises Windows file servers with an Azure file share, enabling multi-site file server consolidation. It supports cloud tiering, which caches frequently accessed files locally on each branch server while freeing up space by tiering cold data to the cloud. This ensures users can continue working during short WAN outages, as local caches provide access to synced files even when connectivity is lost.

Answer

Azure Blob Storage with lifecycle rules, because it can present files to multiple branches.

Answer

A private endpoint to Blob Storage, because it provides local caching for SMB file shares.

Answer

A managed disk shared across the branch servers, because it gives the same content to all locations.

Question 2

Based on the exhibit, why is the administrator's HTTPS test still being denied, and what should be changed?

Accepted Answer

Move Allow-HTTPS-Admin to a priority lower than 200.. The administrator's HTTPS test is denied because Azure Network Security Groups (NSGs) process rules in priority order, from lowest to highest numeric value. The deny rule at priority 200 is evaluated before the allow rule at priority 300, so the HTTPS traffic is blocked. To allow HTTPS traffic, the allow rule must have a lower priority number (e.g., 100) than the deny rule, ensuring it is evaluated first. Option B correctly identifies that moving Allow-HTTPS-Admin to a priority lower than 200 (i.e., a smaller number) will allow the traffic before the deny rule is applied.

Answer

Increase the deny rule priority number from 200 to 300.

Answer

Change Allow-HTTPS-Admin to use protocol Any.

Answer

Assign a public IP address to the VM.

Question 3

Based on the exhibit, the VPN gateway deployment fails during validation. What resource is missing?

Accepted Answer

A public IP address resource associated with the VPN gateway.. A VPN gateway requires a dedicated public IP address resource to establish the IPsec tunnel with the on-premises VPN device. During validation, Azure checks that a public IP address is associated with the gateway; if missing, the deployment fails because the gateway cannot route traffic over the internet or terminate the VPN connection.

Answer

A network security group attached to GatewaySubnet.

Answer

A route table with a default route to the on-premises network.

Answer

A private endpoint for the on-premises VPN device.

Question 4

A lifecycle rule moves blobs to the archive tier after 90 days. A file was archived 2 weeks ago, and a reporting job now needs to read it tomorrow morning. What should you expect?

Accepted Answer

The file must be rehydrated to an online tier before it can be read, so access is delayed.. Blobs in the Azure Archive tier are offline and cannot be read directly. To access the data, you must first rehydrate the blob to an online tier (Hot, Cool, or Cold) using a copy or change-tier operation, which introduces a delay (typically up to 15 hours for standard priority rehydration). The file was archived only 2 weeks ago, so it is still in the Archive tier and requires rehydration before the reporting job can read it tomorrow morning.

Answer

The file is immediately readable, but only through the archive endpoint and at a higher request rate.

Answer

The file is permanently deleted when it enters archive, so the job must use a backup restore.

Answer

The file can be read immediately if the account has read-access geo-redundancy enabled.

Question 5

A company wants to stop users from creating resources in regions that are not approved and also require a Department tag on new resources. Which two tasks are best handled by Azure Policy? Select two.

Accepted Answer

Restrict allowed deployment locations.. Azure Policy can enforce organizational standards by evaluating resource properties against business rules. Option A is correct because the 'Allowed Locations' policy definition restricts users from deploying resources to any region not explicitly permitted, directly addressing the requirement to block unapproved regions. Option B is correct because the 'Require a tag and its value on resources' policy definition can enforce that a Department tag must exist on all new resources, ensuring compliance with tagging requirements.

Answer

Give users Contributor access to the subscription.

Answer

Create Microsoft Entra ID users for contractors.

Answer

Place a CanNotDelete lock on every resource group.

Question 6

A VM cannot connect to another VM on TCP 1433. You need to determine whether an NSG is blocking the flow and identify which rule applies. Which Network Watcher tool should you use?

Accepted Answer

IP flow verify. IP flow verify is the correct Network Watcher tool because it tests whether a packet is allowed or denied to or from a specific VM, based on a 5-tuple (source IP, destination IP, protocol, source port, destination port). For TCP 1433 (SQL Server), you can specify the exact flow parameters, and IP flow verify will evaluate all effective security rules, including NSG rules, and return the specific rule that allowed or denied the traffic.

Answer

Packet capture

Answer

Connection troubleshoot

Answer

Effective routes

Question 7

A team manages three backend servers in one subnet. The servers are replaced periodically, so their private IP addresses change. The NSG must allow inbound traffic from the web tier without updating individual IP addresses each time. Which destination object should be used in the NSG rule?

Accepted Answer

Application security group. An Application Security Group (ASG) allows you to group backend servers logically, regardless of their private IP addresses, and reference that group as the destination in an NSG rule. When servers are replaced and their IPs change, the ASG membership is automatically updated, so the NSG rule continues to apply without manual intervention. This is the correct approach for dynamic workloads where IP addresses are not static.

Answer

Service tag

Answer

Route table

Answer

Private endpoint

Question 8

An application uses two Azure VMs in the same datacenter and must continue through planned maintenance and a single hardware host failure. The administrator does not need separate datacenter protection. Which option should be used?

Accepted Answer

Availability set. An availability set distributes VMs across multiple fault domains (hardware hosts) and update domains within a single Azure datacenter. This ensures that during planned maintenance (update domains) or a single hardware host failure (fault domains), at least one VM remains available. Since the requirement does not include separate datacenter protection, an availability set is the correct choice.

Answer

Availability zones

Answer

Proximity placement group

Answer

Virtual machine scale set

Question 9

Backend virtual machines are rebuilt frequently and often receive different private IP addresses. An administrator must allow the frontend tier to reach the backend tier on TCP 8443 without editing NSG rules every time the backend IP changes. What should the administrator use in the NSG rule?

Accepted Answer

An Application Security Group that contains the backend VMs.. An Application Security Group (ASG) allows you to group backend VMs logically and reference that group in a Network Security Group (NSG) rule. When backend VMs are rebuilt and receive new private IPs, you simply add the new VMs to the same ASG, and the existing NSG rule (which references the ASG as the destination) automatically applies to the new IPs without any manual rule edits. This decouples security policy from dynamic IP addresses, making it the ideal solution for frequently changing backend IPs.

Answer

A static private IP address for each backend VM.

Answer

A user-defined route pointing frontend traffic to the backend subnet.

Answer

A private endpoint for the backend tier.

Question 10

An application on a VM in subnet AppSubnet must access a storage account over the public endpoint. The security team wants to allow traffic only from AppSubnet and does not want to deploy a private endpoint. What should the administrator configure?

Accepted Answer

Enable the Microsoft.Storage service endpoint on AppSubnet and allow that virtual network in the storage account firewall.. Enabling a Microsoft.Storage service endpoint on AppSubnet allows traffic from that subnet to the storage account over the Azure backbone network, while still using the public endpoint. Then, configuring the storage account firewall to allow that virtual network restricts access exclusively to AppSubnet, meeting the security requirement without deploying a private endpoint.

Answer

Disable the storage account firewall and rely on the VM's source IP address.

Answer

Create a private endpoint and leave the firewall set to allow all networks.

Answer

Grant the VM Contributor access to the storage account and the network rule will be enforced automatically.

Question 11

A reporting server must be resized from 4 vCPU to 8 vCPU for a four-hour batch window. The VM name, NIC, private IP, and attached managed disks must stay the same, and the team accepts a brief outage during the change. Which two actions should you choose? Select two.

Accepted Answer

Deallocate the VM before changing its size.. Deallocating the VM (stopping it in the Azure portal) releases the underlying hardware reservation, which is required before changing the VM size to a different SKU. This ensures the VM can be resized to a supported size without conflicts, and the brief outage is acceptable as stated in the scenario.

Answer

Delete the VM and recreate it with a new size.

Answer

Generalize the VM first to preserve the existing configuration.

Answer

Take a snapshot of the OS disk instead of resizing.

Question 12

A VM in VNet A can reach a storage account through a private endpoint, but when the VM resolves the storage account name it still gets the public IP address. What should you configure so name resolution returns the private endpoint address?

Accepted Answer

The private DNS zone linked to the VNet. When a private endpoint is created for a storage account, the DNS configuration must be updated so that the storage account's fully qualified domain name resolves to the private endpoint's private IP address instead of the public IP. Linking a private DNS zone (privatelink.blob.core.windows.net) to the virtual network and configuring a virtual network link ensures that the VM's DNS queries for the storage account are answered with the private endpoint IP. Without this, the VM continues to use the public IP from public DNS.

Answer

A user-defined route to the storage private endpoint

Answer

A resource lock on the storage account

Answer

A managed identity for the VM

Question 13

A business-critical storage account must survive a zone outage in the primary region and also keep a read-only copy in the paired region for reporting if the primary region becomes unavailable. Which redundancy option should you choose?

Accepted Answer

RA-GZRS because it provides zone redundancy and read access to the secondary region.. (RA-GZRS) is correct because it combines zone-redundant storage (ZRS) within the primary region, ensuring data survives a zone outage, with read-access geo-redundant storage (RA-GRS) to the paired region, providing a readable secondary copy for reporting if the primary region becomes unavailable. This meets both requirements: zone-level fault tolerance and read-only access to the secondary region during a primary outage.

Answer

ZRS because it protects against a single datacenter failure.

Answer

GZRS because it provides a readable secondary region by default.

Answer

RA-GRS because it provides zone redundancy and read access to the secondary region.

Question 14

A security team requires all outbound internet traffic from a workload subnet to pass through an NVA at 10.1.4.4. The subnet is already associated with an NSG that allows the traffic. Which UDR should the administrator add to the route table for that subnet?

Accepted Answer

Destination 0.0.0.0/0 with next hop type Virtual appliance and next hop IP 10.1.4.4.. A User Defined Route (UDR) with destination 0.0.0.0/0 and next hop type 'Virtual appliance' forces all outbound internet traffic from the subnet to be forwarded to the NVA at 10.1.4.4 for inspection. The 0.0.0.0/0 prefix matches all internet-bound traffic, and the 'Virtual appliance' next hop type enables routing to a private IP address within the virtual network, overriding the default system route that would otherwise send traffic directly to the Internet.

Answer

Destination 10.1.4.4/32 with next hop type Internet.

Answer

Destination 0.0.0.0/0 with next hop type Virtual network gateway.

Answer

Destination 10.1.4.0/24 with next hop type None.

Question 15

A VM in AppSubnet must reach a database VM in DbSubnet on TCP 1433. AppSubnet's NSG has an outbound deny rule for TCP 1433 to Any at priority 200. DbSubnet's NSG has an inbound allow rule for TCP 1433 from ASG-App to ASG-Db at priority 300. Both NICs are in the correct application security groups. Connectivity tests fail. What should the administrator change?

Accepted Answer

Create an outbound allow rule on AppSubnet with a lower priority number than 200 for TCP 1433 to ASG-Db.. The AppSubnet's NSG has an outbound deny rule for TCP 1433 to Any at priority 200, which blocks all outbound traffic on that port regardless of destination. To allow the VM in AppSubnet to reach the database VM in DbSubnet, an outbound allow rule must be created with a lower priority number (e.g., 100) so it is evaluated before the deny rule. This rule should specify the destination as ASG-Db (the application security group of the database VM) to precisely permit the required traffic.

Answer

Remove the inbound allow rule from DbSubnet so the default rules can take over.

Answer

Move the inbound allow rule on DbSubnet to priority 100 so it is evaluated sooner.

Answer

Assign the database VM NIC to ASG-App so the destination rule matches a broader group.
