Reasons to Choose Our Nutanix NCP-MCI Exam Dumps

A) This statement is incorrect because there is no static threshold set to trigger a critical alert at 6000 MB. The graph shows a peak that goes above 6000 MB, but the alert configuration below does not specify a static threshold at this value.

B) This is the correct statement. The configuration under 'Behavioral Anomaly' is set to alert every time there is an anomaly, with a critical level alert set to trigger when the I/O working set size is between 0 MB and 4000 MB. The graph illustrates that the anomalies (highlighted in pink) occur when the working set size exceeds the normal range (blue band). Therefore, any anomaly detected above 4000 MB would trigger a critical alert.

C) This statement is incorrect because there is no indication that a warning alert is configured to trigger after 3 anomalies. The exhibit does not show any configuration that specifies an alert based on the number of anomalies.

D) This statement is incorrect as there's no indication that a warning alert will be triggered based on the I/O working set size exceeding the blue band. The alert settings are configured to ignore anomalies below 4000 MB and to trigger a critical alert for anomalies above this threshold.

The settings displayed in the exhibit are typically part of Nutanix's Prism infrastructure management platform, which can set various thresholds for performance metrics and trigger alerts based on those thresholds. The behavior is defined in the Prism documentation where the alert configuration is outlined.

The output in the exhibit indicates that the node's network interfaces (eth0-eth3) are bonded together using LACP (Link Aggregation Control Protocol) with 'balance-tcp' as the bonding mode and LACP speed set to 'fast'. For LACP to function correctly, the switch ports to which the node is connected must also be configured to support LACP. If the ports on the upstream switch are not configured for LACP, the bond will not be able to establish properly, and the node will not communicate effectively on the network, making it undiscoverable when attempting to expand the cluster.

The absence of an operational LACP configuration could prevent the new node from joining the existing cluster as the node's network interfaces would not be able to pass traffic correctly. This can be verified by checking the switch configuration to ensure that the ports are set to participate in an LACP bond.

The other options, such as a firewall blocking discovery traffic (Option A) or the node being on different VLANs (Option C), are possible causes for a node not being discovered, but given the specific command output provided, the most likely cause is related to the switch port configuration for LACP. Option D, regarding completing LACP configuration after cluster expansion, is not correct because LACP needs to be operational for the node to communicate with the cluster during the expansion process.

Proper LACP configuration is critical for network communication in a Nutanix AHV cluster, and this is covered in detail in the Nutanix AHV and Networking documentation. It outlines the steps for configuring network bonds and LACP on both the AHV hosts and the connecting network infrastructure.

The critical alerts listed are indicating that the default passwords are still in use for IPMI, the host, and the Controller Virtual Machine (CVM). This suggests that the passwords for these components were not changed from the default during the initial cluster configuration and deployment process, which is a critical security practice.

A) CVM password changes: The alert for the CVM using the default password indicates that the CVM password has not been changed. It is a standard security measure to change default passwords to prevent unauthorized access.

C) Host password changes: Similarly, the alert for the host using the default password indicates that the default password for the host has not been updated. This applies to the passwords used to access the hypervisor host directly.

Changing default passwords is a critical step in securing the Nutanix environment. This is highlighted in Nutanix's best practices and security guidelines, which recommend changing default passwords as part of the initial configuration to ensure that the environment is not left vulnerable to unauthorized access due to known default credentials. This process is typically part of the initial setup procedures outlined in the Nutanix documentation for cluster deployment and security configuration.

The IPMI alert also points to the need for changing default passwords, but since IPMI (Intelligent Platform Management Interface) is not specifically mentioned in the provided options, it falls under the broader category of host-level password changes, which would be covered by option C.

BIOS password changes (Option B) and Password policy changes (Option D) are also important but were not directly flagged by the alerts mentioned. BIOS password changes are usually a separate task and not indicated by the alerts given, while password policy changes are related to the policies governing password complexity and rotation rather than the initial password setup.

According to the web search results, three storage optimizations that should be set on a dedicated storage container for a VDI solution with persistent desktops are compression, deduplication and erasure coding. Compression is a technique that reduces the size of data by removing redundant information. Deduplication is a technique that eliminates duplicate copies of data blocks and stores only unique blocks.Erasure coding is a technique that increases usable capacity by reducing the replication factor of data blocks and using parity information instead7.These three optimizations can improve performance and save storage space for VDI workloads, especially during a node failure event when data needs to be rebuilt from parity information8.The administrator can enable these optimizations by using Prism Element web console or ncli command-line interface9.

According to the web search results, one recommended configuration change to improve throughput for a custom backup application that requires a 2TB disk and runs on Windows is to span the 2TB disk across four vDisks. Spanning is a technique that allows you to create a single logical disk from multiple physical disks.Spanning can improve throughput by distributing I/O requests across multiple disks and reducing contention5. To span a disk across four vDisks, the administrator should create four vDisks of equal size (500 GB each) and attach them to the VM.Then, in Windows Disk Management, create a spanned volume from the four vDisks and format it as NTFS6.
