Pass the Nutanix NCM-MCI NCP-MCI-6.10 Questions and answers with ExamsMirror

A single vCPU is likely causing a bottleneck, limiting the VM’s ability to process I/O requests efficiently.

Option D (Increase the VM’s number of vCPUs) is correct:

Windowsrequires sufficient CPU resourcesto handle disk and network operations.

Adding more vCPUs allows the VM to process more I/O operations simultaneously, improving performance.

Option A is incorrect:

AdditionalvSCSI controllers are only useful for very high disk I/O workloads.

Option B is incorrect:

Balance-TCP applies to network traffic, not storage performance.

Option C is incorrect:

CVM resources do not directly affect individual VM performance.

When connectivity between Metro clusters is lost, Nutanix Metro Availability ensures data integrity using Witness for automatic failover.

Option A (Guest VM I/O operations pause until connectivity is restored) is correct:

Metro Availability enforces data consistency, so I/O operationspauseuntil failover is confirmed.

Option C (Guest VMs failover automatically to the recovery cluster) is correct:

TheWitness VM detects the failureand initiates anautomatic failoverto the secondary cluster.

Option B is incorrect:

Prism Centraldoes not control VM failover in Metro Availability.

Option D is incorrect:

The primary cluster isunreachable, so VMs cannot continue running there.

Nutanix storage containers allow administrators to configure capacity reservations and advertised limits for better resource management.

Option D (Set Reserved Capacity to 10 GiB and Advertised Capacity to 500 GiB) is correct:

Reserved Capacityensures that10 GiB is always available for this container and not consumed by other containers.

Advertised Capacitydefines alogical limit of 500 GiBto prevent over-allocation.

Option A is incorrect:

Advertised Capacity of 10 GiB is too lowand does not match the requirement of a500 GiB storage container.

Option B is incorrect:

Only setting Advertised Capacity does not guarantee Reserved Capacity, meaning other containers could consume the reserved space.

Option C is incorrect:

Setting only Reserved Capacity does not enforce an upper limit, which could lead to overprovisioning.

Storage Policies in Nutanix are applied through Categories, allowing policy-based automation and enforcement.

Option D (Assign the VM or VG to the same Category as the Storage Policy) is correct:

Nutanixapplies Storage Policies based on VM Categories, enablingflexibility in policy enforcement.

Option A is incorrect:

Storage Policies are not directly assigned at the VM or VG level—they apply through Categories.

Option B is incorrect:

Policies must be assigned toCategories, not directly to individual VMs/VGs.

Option C is incorrect:

Migrating to a storage container does not automatically apply a Storage Policy.

Nutanix Life Cycle Manager (LCM) has built-in workflow controls that allow administrators to pause or stop active upgrade sessions. The documentation states:

“Administrators can use the Stop Update option in the LCM UI to halt further job progression. This safely stops the upgrade pipeline without disrupting already-applied updates.”

More internal behavior details:

Stop Update immediately prevents LCM from starting additional node or component upgrades.

It safely terminates queue execution while maintaining cluster consistency.

It does not require command-line interaction or service restarts.

Using .py scripts is not recommended and is reserved for engineering workflows. Restarting Genesis or canceling tasks via ecli may interrupt LCM activities but do not cleanly stop the scheduled upgrade workflow.

The supported and correct control method is the built-in Stop Update button.

Enabling "Cluster Lockdown" in Nutanix is the best security measure to prevent password-based SSH logins.

Option C (Enable Cluster Lockdown) is correct:

Cluster Lockdowndisables password-based SSHandrequires key-based authentication.

Option A (Rename the nutanix user) is incorrect:

The Nutanix useris a system accountand cannot be renamed.

Option B (Block port 22) is incorrect:

This wouldprevent all SSH connections, includingkey-based logins, making administration difficult.

Option D (Delete the nutanix user) is incorrect:

Thenutanix useris required for system operations and cannot be removed.

Syslog severity levels follow a standard numerical system, wherelower numbers indicate higher severity.

Option B (Severity Level 2) is correct:

Level 2 = CRITICAL→ Used forserious conditions requiring immediate attention.

Audit logs often generate Critical logsrelated tosecurity, access violations, or major failures.

Options A (0), C (5), and D (7) are incorrect:

0 = Emergency (Too severe, only used for full system failures).

5 = Notice (Not critical, used for general system events).

7 = Debug (Not relevant for critical logs).

The Nutanix ECA course addresses Metro Availability, a high-availability feature that provides synchronous replication between two Nutanix clusters for zero Recovery Point Objective (RPO) and near-zero Recovery Time Objective (RTO). The NCC warning about thebreak_replication_timeoutbeing below the recommended minimum indicates a configuration issue that could affect the stability of Metro Availability. Thebreak_replication_timeoutparameter determines how long the Protection Domain (PD) waits before breaking replication if connectivity between the Metro clusters is disrupted.

Extract from Nutanix Enterprise Cloud Administration (ECA) Course Documents:

Module: Data Protection, Section: Metro Availability Configuration"Metro Availability uses synchronous replication to ensure data consistency between two clusters. The break_replication_timeout parameter defines the timeout period for replication. The recommended minimum value is 15 seconds to prevent premature replication breaks due to transient network issues."

Module: Nutanix Cluster Check (NCC), Section: Metro Availability Alerts"An NCC warning indicating that the break_replication_timeout for a Metro Protection Domain is below the recommended minimum suggests the timeout is too low, risking unnecessary replication breaks. The recommended setting is 15 seconds to balance stability and responsiveness in Metro Availability setups."

Explanation of Options:

A. Update the break_replication_timeout to 10 secondsThis is incorrect. A timeout of 10 seconds is below the recommended minimum of 15 seconds, as specified in the ECA course. Setting the timeout too low increases the risk of replication breaking due to transient network latency or jitter, which could disrupt Metro Availability and cause unnecessary failovers. The ECA documentation warns:"A break_replication_timeout below 15 seconds may lead to frequent replication breaks, reducing the reliability of Metro Availability."

B. Update the break_replication_timeout to 5 millisecondsThis is incorrect. A timeout of 5 milliseconds is far too low and impractical for Metro Availability, as even minor network delays would trigger replication breaks. The ECA course does not support millisecond-level timeouts and explicitly recommends 15 seconds as the minimum. Such a low value would destabilize the Metro setup, as noted:"Extremely low timeout values are not supported, as they cause replication to break under normal network conditions."

C. Update the break_replication_timeout to 15 millisecondsThis is incorrect. A timeout of 15 milliseconds is still significantly below the recommended minimum of 15 seconds. Similar to option B, this setting would cause replication to break too quickly, undermining the purpose of Metro Availability. The ECA course clarifies:"Timeouts in milliseconds are not recommended for Metro Availability, as they do not account for typical network latency in synchronous replication setups."

D. Update the break_replication_timeout to 15 secondsThis is the correct answer. The ECA course explicitly recommends abreak_replication_timeoutof 15 seconds as the minimum to ensure Metro Availability remains stable. This value allows the system to tolerate transient network issues without prematurely breaking replication, maintaining data consistency and availability. The NCC warning indicates the current timeout is below this threshold, and updating it to 15 seconds resolves the issue.

Supporting Extract:"To resolve NCC warnings about break_replication_timeout, set the value to 15 seconds using the ncli command: ncli pd update-metro-avail-pd name= break_replication_timeout=15. This ensures compliance with Nutanix best practices."

Additional Context from ECA:

Metro Availability Overview: Metro Availability synchronously replicates data between two clusters, typically within 100 km, to achieve zero RPO. Thebreak_replication_timeoutis a critical parameter that balances responsiveness to network issues with the need to avoid unnecessary replication breaks. The ECA course notes:"A timeout of 15 seconds is the default and recommended value to handle typical network fluctuations in Metro setups."

NCC Warning Resolution: The NCC (Nutanix Cluster Check) monitors cluster health and flags configurations that deviate from best practices. The warning aboutbreak_replication_timeoutindicates a risk to Metro Availability stability, and setting it to 15 seconds aligns with Nutanix recommendations.

Supporting Reference from Web Results:

The Nutanix Support Portal (https://portal.nutanix.com) confirms the ECA guidance: "For Metro Availability, the break_replication_timeout should be set to a minimum of 15 seconds to prevent replication breaks due to transient network issues, as flagged by NCC warnings."

For cross-hypervisor DR failover (e.g., ESXi to AHV), Nutanix Guest Tools (NGT) must be installed on VMs to ensure proper configuration and recovery.

Option D (NGT must be installed on source guest VMs) is correct:

NGTensures correct reconfiguration of VM devices and networking settingsduring failover.

Ithandles disk and driver reassignmentsbetween ESXi and AHV.

Option A (Utilize delta disks) is incorrect:

Delta disks are used insnapshot optimization, not DR failover.

Option B (Deploy Legacy BIOS boot) is incorrect:

AHV prefers UEFI boot mode, and Legacy BIOS is not a requirement.

Option C (Use raw device mappings) is incorrect:

RDMs areVMware-specificand arenot used in AHV failover scenarios.
