76. Frage
An administrator is provisioning a new Linux virtual machine.
Which timezone is recommended for this VM?
Antwort: C
Begründung:
UTC is the recommended timezone selection when creating a Linux VM on AHV. Nutanix specifically states that the real-time clock of a Linux VM must operate in UTC. Selecting the UTC timezone ensures that the guest's hardware-clock interpretation is consistent with Linux conventions and avoids time shifts caused by local timezone or daylight-saving changes.
Time consistency is essential for authentication, application logging, distributed databases, monitoring, certificate validation and event correlation. The guest operating system can still display a regional timezone to users at the application or operating-system level while maintaining its underlying hardware clock in UTC.
"Local" can cause the guest to interpret the virtual hardware clock according to a regional offset, producing incorrect timestamps after migration, reboot or daylight-saving transitions. "Cluster" is not a supported timezone designation for this VM setting. RTC means real-time clock and describes the clock mechanism rather than a selectable geographic timezone.
The VM should also use a reliable NTP source after deployment so its operating-system time remains synchronized.

77. Frage
Which Nutanix solution provides microsegmentation and application-centric security policies for VMs?
Antwort: A
Begründung:
Flow Network Security provides application-centric microsegmentation and distributed security-policy enforcement for Nutanix workloads. It uses categories and application context to define which workloads may communicate, rather than depending exclusively on static IP addresses or physical VLAN boundaries.
Policies can follow VMs as they move or scale within supported Nutanix environments.
Microsegmentation limits east-west communication between application components and reduces the potential lateral movement of malware or unauthorized users. Administrators can define policies for application tiers, environments, user groups and isolation requirements, then manage those policies centrally through Prism Central. Flow Network Security also provides traffic visualization and policy-monitoring capabilities before enforcement.
AHV supplies the virtualization and host-compute layer but is not, by itself, the security-policy product identified by the question. AOS provides distributed storage, resilience and data services. Nutanix Disaster Recovery manages workload protection, replication and recovery rather than distributed microsegmentation.

78. Frage
On which entity is Replication Factor configured?
Antwort: D
Begründung:
Replication Factor is configured on a storage container. It determines how many copies of the data associated with that container are maintained across the Nutanix distributed storage fabric. The official Prism 7.5 definition states that replication factor is the number of copies of data maintained on a storage container within a cluster. For example, RF2 maintains two copies, whereas RF3 maintains three copies and consequently requires a cluster capable of providing the corresponding fault-tolerance level.
A storage pool aggregates physical storage resources, but it does not independently establish the replication policy for guest data. A protection domain defines which entities are protected and controls snapshot or replication schedules for disaster recovery; it is not the administrative location for configuring local data-copy count. "Replication Policy" is therefore a distractor representing data-protection behavior rather than an AOS storage entity.
Replication factor also affects usable capacity because additional copies consume physical storage.
Administrators must therefore align the container's replication factor with the cluster's available fault domains and required resilience. Prism requires RF3 to be configured individually for the applicable containers after the cluster supports the necessary fault-tolerance level.

79. Frage
Which action will ensure AHV automatically assigns an IP address to a VM?
Antwort: B
Begründung:
AHV provides integrated IP Address Management through a managed virtual network. Enabling IPAM on the VM's existing virtual network and defining a DHCP address pool allows AHV to intercept the guest's DHCP request and allocate an available address from that pool. During VM or vNIC configuration, the administrator can then select DHCP assignment, allowing the platform to manage address allocation automatically.
Option B is the complete action for converting the VM's current network into an IPAM-capable network.
Although an IPAM-enabled network can also be created from the beginning, option C creates a different network and does not, by itself, ensure that the existing VM is connected to it. Option A may provide conventional external DHCP, but it does not constitute AHV-managed IPAM. Option D is invalid because the Controller VM is not intended to be repurposed as an administrator-configured DHCP server.
The DHCP pool must contain valid addresses for the subnet and exclude reserved infrastructure addresses.
The VM must also be attached to that managed network and configured for DHCP; otherwise, AHV cannot complete the allocation.

80. Frage
A Prism administrator wants Nutanix Support to receive proactive telemetry so that hardware failures can be detected automatically.
Which feature should be verified is enabled?
Antwort: B
Begründung:
Pulse is the Nutanix telemetry capability that securely transmits purpose-specific diagnostic and configuration data to Nutanix Support and Nutanix Insights. When Pulse and the associated Remote Diagnostics functionality are enabled, Nutanix can analyze cluster health information proactively, identify developing problems, collect relevant diagnostic information, and automate support workflows for critical conditions such as disk or DIMM failures.
Pulse is enabled on a per-cluster basis and uses an encrypted communication channel. It does not serve the same purpose as general event forwarding. Nutanix documents that Pulse does not collect guest-VM application data, user data, administrator credentials, or personally identifiable information. The transmitted system-level information is used to improve diagnosis and support responsiveness.
Syslog sends selected logs to a customer-controlled logging platform. SNMP provides monitoring information and traps to an external network-management system. SMTP enables email delivery for configured alerts. All three are valid monitoring integrations, but none sends the specialized diagnostic telemetry required for Nutanix's proactive support service.
Therefore, the administrator should verify Pulse enablement, outbound connectivity, proxy configuration where applicable, and Remote Diagnostics status.
