Case Study 2: The "Zombie" Node Mystery
A Senior Support Engineer is troubleshooting a 4-node cluster. Node-03 was physically replaced due to hardware failure. The node was re-imaged, renamed to Node-03, and joined to the domain.
When attempting to add Node-03 back to the cluster (Add-ClusterNode), the operation fails immediately.
However, Get-ClusterNode on the active cluster shows only Node-01, 02, and 04. Node-03 is not in the list.
On Node-03 itself, Get-ClusterNode returns "The term 'Get-ClusterNode' is not recognized" (Cluster feature not installed yet).
What "Ghost" configuration is blocking the add operation?

A.Node-03's DNS A-record resolves to the IPv6 address of the decommissioned network interface, causing the cluster wizard to attempt communication with a non-existent endpoint.
B.An existing Azure Arc resource for Node-03 remains registered in the Azure portal with a 'Connected' status, locking the hostname and preventing reintegration into the on-premises cluster environment.
C.Active Directory's Cluster Name Object retains the old Node-03 hostname in the msDS-AdditionalDnsHostName attribute, triggering a Kerberos SPN conflict during node validation.
D.The replacement server's physical disks retain the prior cluster's signature in metadata headers due to reused drives or prior cluster membership without disk sanitization.

Question No : 4

What is the primary operational difference between using "Device Code" flow versus a "Service Principal" when registering Azure Local nodes with Azure Arc?

A.Device Code authentication provides enhanced security by mandating a hardware FIDO2 security key physically connected to the server during the authentication ceremony, while Service Principals utilize comparatively less secure text-based password secrets for credential validation.
B.Device Code flow is interactive (user enters code on another device), blocking automated bulk deployments; Service Principals enable headless scripted onboarding for unattended scenarios.
C.Service Principals are deprecated for Azure Arc registration per current documentation and will be removed in the upcoming agent release (v1.5+); Device Code is designated as the only Microsoft-supported method for production environments.
D.Device Code authentication establishes a persistent association with the user’s identity within the Azure Active Directory tenant context, whereas Service Principals created with default expiration parameters are automatically scheduled for deletion after a 24-hour window.

Question No : 5

A DevOps Engineer encounters the error code AZCM0016 during an automated onboarding sequence.
[Error] AZCM0016: The resource group 'rg-cluster-nodes' was not found.
[Context] Subscription: 'sub-123', Location: 'eastus'
The engineer verifies that the Service Principal has "Contributor" rights on the Subscription.
Why did the command fail?

A.The Resource Group name contains uppercase letters, which is invalid per Azure naming conventions (lowercase only), and the azcmagent CLI rejects it.
B.The azcmagent connect command does not auto-create Resource Groups. Pre-creation of the target Resource Group in Azure is required before registration.
C.The Resource Group is located in the 'westus' region, while the command specifies 'eastus', resulting in a lookup failure that returns 'Not Found'.
D.The Service Principal requires "Owner" role assignment at the subscription level to create a missing Resource Group during the automated onboarding sequence.

Question No : 6

A Network Administrator is navigating the sconfig menu on Node-01 to configure the management interface.

Which numeric option must the administrator select to initiate the configuration of a Static IP address, Subnet Mask, and Default Gateway?

A.Option 8
B.Option 1
C.Option 4
D.Option 7

정답:

Question No : 7

A DevOps Engineer runs the azcmagent connect command using a Service Principal but receives an "Authorization Failed" error.
[Error] The client 'guid-1111' with object id 'guid-2222' does not have authorization to perform action 'Microsoft.HybridCompute/machines/write' over scope '/subscriptions/sub-123/resourceGroups/rg-nodes/providers/Microsoft.HybridCompute/machines/Node-01'.
[Code] AuthorizationFailed
What is the root cause of this error?

A.The Microsoft.HybridCompute resource provider is not registered in the Azure subscription, which would generate a MissingSubscriptionRegistration error instead of an RBAC denial.
B.The Resource Group rg-nodes has a CanNotDelete lock applied; however, this lock type only restricts deletions and permits write operations, and lock-related errors explicitly reference 'ScopeLocked'.
C.The Service Principal authenticated successfully, but the assigned role lacks the Microsoft.HybridCompute/machines/write permission for the Machine resource in the Resource Group.
D.The Service Principal authentication failed due to an invalid secret, preventing the RBAC authorization check from executing.

Question No : 8

A Systems Integrator is performing a "Fusion" validation of the OS Time Zone defaults versus the Cluster requirements.
- Seed 1 (OS Default): A fresh installation of Azure Stack HCI OS defaults to Pacific Standard Time (PST).
- Seed 2 (Cluster Req): The cluster will span two sites: London (GMT) and Paris (CET).
# PowerShell Time Check
PS C:\> Get-TimeZone
Id: Pacific Standard Time
BaseUtcOffset: -08:00:00
# Cluster Requirement
All nodes must use UTC to simplify log correlation across time zones.
What is the operational risk if this default is not changed before forming the cluster? (Choose 2.)

A.Kerberos authentication will fail between nodes if the *Local Time* differs, even if the UTC time is synchronized via NT
B.The Azure Arc registration will be rejected because the "Region" tag (e.g., West Europe) must match the OS time zone.
C.Log analysis and troubleshooting will be significantly more difficult, as Event Viewer timestamps will be offset by 8/9 hours from the actual incident time in Europe.
D.The cluster creation wizard will fail because it validates that all nodes must match the time zone of the deployment workstation.
E."Scheduled Tasks" and maintenance windows defined in local time (e.g., 2:00 AM) will execute at the wrong time (e.g., 10:00 AM GMT), potentially impacting production workloads.

Question No : 9

A Systems Integrator attempts to run Invoke-AzStackHciEnvironmentChecker against remote nodes Node-01 and Node-02. The command fails immediately with an authentication error related to "Double Hop".
What is the required remediation to allow the tool to validate remote nodes from a management workstation?

A.To ensure Layer 2 network connectivity, configure the management workstation to reside on the identical VLAN segment as the HCI cluster nodes.
B.Log in directly to each cluster node using local administrator credentials (via console or RDP) and execute the Environment Checker tool locally on every node.
C.Enable the predefined Windows Firewall inbound rule group "File and Printer Sharing" on all cluster nodes to permit essential SMB protocol traffic required for validation.
D.Enable CredSSP on the management workstation and all target nodes to permit delegation of user credentials required for multi-hop remote validation tasks.

Question No : 10

A Systems Integrator is verifying the connectivity prerequisites for a new Azure Local cluster deployment. The Environment Checker tool reports a warning regarding "Token Endpoint Connectivity".
- Seed 1 (Time Sync): The node's system time is skewed by +15 minutes relative to the NTP server.
- Seed 2 (Auth Endpoint): Connectivity to login.microsoftonline.com is verified as Open (TCP 443).
# Environment Checker Output
[PASS] Network: login.microsoftonline.com (Reachable)
[FAIL] Auth: Token Acquisition Test
[DETAIL] Status: 400 Bad Request
[DETAIL] Message: AADSTS500133: Assertion is not within its valid time range.
# System Time Check
Local Time: 2026-02-15 10:15:00
NTP Time: 2026-02-15 10:00:00
Based on the interaction between the System Time and the Authentication requirement, why is the token acquisition failing despite network connectivity being successful? (Select all that apply.)

A.During HTTPS deep packet inspection, firewalls may alter headers and remove the timestamp field critical for OAuth token validation.
B.Azure AD rejects authentication requests when client clock skew exceeds 5 minutes, as timestamps in JWT or Kerberos tokens become invalid for security.
C.Error AADSTS500133 confirms network connectivity succeeded, but Azure rejects the timestamped token request due to invalid time range.
D.Restarting the agent forces a hardware clock (RTC) re-sync attempt to address time skew before reattempting the authentication connection.
E.The HTTP 400 Bad Request status code is misinterpreted as indicating login.microsoftonline.com is unreachable, leading the agent to fall back to an expired cached token.

A Solution Architect is designing the networking for a multi-site Azure Local deployment. The customer's legacy data center switches do not support Data Center Bridging (DCB) or DCBX. However, the customer requires RDMA functionality for high-performance storage replication between the nodes at each site.
Which of the following design decisions allows the architect to meet the requirement given the hardware constraints? (Select all that apply.)

A.Implement switchless storage by directly interconnecting Dell AX node storage ports via DAC cables, excluding legacy switches from the storage replication data path.
B.Configure legacy switches to enable IEEE 802.3x "Global Pause" on all ports, halting all link traffic to simulate rudimentary flow control.
C.Select network adapters featuring "Soft-RoCE" (software-based RoCE implementation) to emulate DCB capabilities within the host OS kernel, bypassing physical switch DCB requirements specifically for RDMA traffic paths.
D.Use iWARP RDMA protocol instead of RoCEv2 for the cluster; iWARP handles congestion via TCP, eliminating dependency on DCB-enabled switches.
E.Utilize Network ATC (Automatic Traffic Control) to define a custom intent that overrides default RoCEv2 protocol selection and enforces standard TCP/IP for all storage traffic flows.

Question No : 12

Why is relying on standard Windows Update an Anti-Pattern for maintaining VSR compliance on Dell AX nodes? (Choose 2.)

A.The Vendor Support Recipe (VSR) compliance policy strictly permits only inbox drivers included with the base Windows OS installation media; any driver update sourced externally―including Dell-provided packages―is deemed a violation of the hardware support agreement.
B.Windows Update supplies generic drivers exceeding VSR baseline versions without Dell AX hardware validation, introducing potential instability or regressions in integrated subsystems.
C.By default, Azure Stack HCI host firewall rules explicitly block all outbound network traffic destined for Windows Update servers, requiring administrators to manually configure firewall exceptions to enable update downloads.
D.Windows Update handles driver updates only and does not manage firmware updates, creating a driver-firmware mismatch that leads to system drift and incompatibility.
E.Windows Update mandates a continuously active interactive user session logged into the server console to initiate and complete all driver installation processes on Azure Stack HCI nodes.

Which specific blade or service view in the Azure Portal provides the definitive GUID representing the Azure Active Directory (Entra ID) Tenant ID?

A.Subscriptions > Settings > Directory
B.Microsoft Entra ID > Overview > Basic Information
C.Cost Management + Billing > Invoices > Properties
D.Azure Arc > Infrastructure > Service Principals

Question No : 14

A Site Reliability Engineer is diagnosing a performance issue on an Azure Local cluster using RoCEv2 RDMA. The storage throughput drops significantly during high load, and the switch port counters show a high number of "Discards" or "Drops".
The engineer verifies that Priority Flow Control (PFC) is enabled on the OS network adapters for Priority 3.
What is the most likely cause of the packet drops on the switch side?
A. Global Pause (IEEE 802.3x) is enabled on the switch ports, conflicting with Priority Flow Control (PFC) and causing non-selective traffic pauses across all priorities.
B. The switch interface MTU is configured to 9214 bytes, a value incorrectly deemed too large for RoCEv2 header processing in this specific deployment context.
C. Switch ports lack PFC configuration for Priority 3; Pause frames from the host are ignored, resulting in buffer overflow and packet drops.
D. The host OS has the DCBX "Willing" bit set to false, preventing adoption of the switch's proposed flow control parameters during negotiation.

정답: C

Question No : 15

A Systems Integrator validates the DNS Dynamic Update settings for the Active Directory zone.
- Zone: contoso.com
- Dynamic Updates: "Secure only"
- Issue: The Cluster Name Object (CNO) fails to register its IP address in DNS after a failover.
What is the likely permission issue in Active Directory DNS?

A.The Cluster IP address is in a subnet that is not defined in AD Sites and Services.
B.The DNS Scavenging interval is set too low (e.g., 1 hour), deleting the record immediately.
C.The CNO computer account does not have "Write" permission on its own DNS A-record.
D.The zone must be set to "Non-secure and Secure" to allow cluster updates.
