In a 20-node ESXi deployment, the customer needs additional resiliency to survive the loss of two nodes concurrently.
Which configuration should the consultant use to ensure that the appropriate resources are available?
A. Storage reservation for 10%; HA admission control for 10%, cluster RF3
B. Storage reservation for 5%; HA admission control for 5%, cluster RF2
C. Storage reservation for 5%; HA admission control for 5%, cluster RF3
D. Storage reservation for 10%; HA admission control for 10%, cluster RF2
Explanation: To ensure additional resiliency in a 20-node ESXi deployment capable of surviving the concurrent loss of two nodes, the consultant should configure the system with a storage reservation and HA (High Availability) admission control each set to 5%, combined with a cluster redundancy factor (RF) of 3. RF3 provides the capability to tolerate the failure of up to two nodes without data loss, thus enhancing the cluster's resilience. This configuration is optimal for maintaining cluster availability and integrity during multiple node failures.References: Nutanix Bible, Nutanix University
A consultant is working on an expansion project for a customer that has an existing 7-node
RF2 cluster. The customer has purchased four more nodes to add to the cluster. All of the
hardware is identical between the existing hardware and newly purchased hardware.
Currently, the 7-node cluster has the following utilization:
A. Expand the cluster with the additional nodes and enable Reserve Rebuild Capacity.
B. Enable Reserve Rebuild Capacity and expand the cluster with the additional nodes
C. Expand the cluster with the additional nodes and enable HA reservation.
D. Enable HA reservation and expand the cluster with the additional nodes.
Explanation: The most efficient and safest way to implement the customer's desire to reserve storage capacity for future node failures after expanding their existing 7-node RF2 cluster with four additional nodes is to first expand the cluster with the additional nodes, and then enable the Reserve Rebuild Capacity setting. This approach allows the cluster to immediately benefit from increased storage and other resources provided by the additional nodes, which can then be partially reserved to handle potential future failures. This method ensures both an increase in total capacity and the preservation of operational integrity during node failures.
Refer to the exhibit.
A. Link Aggregation
B. Range Autofill
C. Network Segmentation
D. Multi-homing
Explanation: During the deployment of a cluster using the Nutanix Foundation, ensuring all IP ranges are correctly configured is crucial for successful connectivity and deployment. "Range Autofill" is a feature in Foundation that automatically populates IP address fields based on the first IP provided, ensuring consistency and correctness across multiple nodes being deployed simultaneously. This feature helps avoid manual entry errors and ensures all nodes are configured with appropriate IP addresses that fall within the specified range.
When utilizing the Nutanix cluster As Built Document generator, which two configuration elements should a consultant provide when running the run_as_built.exe command? (Choose two.)
A. Data Services IP
B. Cluster IP
C. Remote Site IP
D. Customer Name
Explanation: When using the Nutanix cluster As Built Document generator, the necessary configuration elements to provide when running the run_as_built.exe command include the Cluster IP (B) and the Customer Name (D). The Cluster IP is required to properly identify and communicate with the cluster to gather configuration and operational data. The Customer Name is typically used to personalize the documentation, making it specific to the client's deployment, which is useful for record-keeping and future reference purposes.
During a Site Readiness Check, a customer informed the consultant that there is no NTP server currently configured in the environment. Which two statements should the consultant consider for continuing the cluster deployment? (Choose two.)
A. An NTP server is not required for cluster Foundation and can be added later.
B. If an NTP server is provided using FQDN, a DNS server is required.
C. At least 3 NTP servers must be provided in a comma-separated list.
D. At least one external NTP server must be used to complete Foundation process.
Explanation: For continuing the cluster deployment without an NTP server immediately available: A. An NTP server is not required for the initial foundation process of the cluster and can indeed be added later. This allows the deployment to proceed without delays, although it's critical to add NTP synchronization as soon as possible post-deployment to ensure proper cluster time management. B. If an NTP server is to be provided using an FQDN, then a DNS server must indeed be available. This is because the FQDN needs to be resolved to an IP address, which requires DNS resolution services. Options C and D are not strictly required as per Nutanix deployment standards; a single NTP server can suffice initially, and there's no requirement for it to be external or in a comma-separated list unless specifically dictated by network or organizational policies.
A customer design calls for link aggregation. Despite the consultant verifying all hosts are correctly configured for fallback per Nutanix best practices, initial testing reveals the aggregate bond fails to pass traffic and shows a status of configured. What is the most likely cause for the bond disabling and reporting a "configured" status?
A. The uplinks in the bond need to be turned on.
B. The ports need to be flushed.
C. Failed negotiation due to misconfiguration on ToR switches.
D. The bond needs to be reconfigured for balance s_b mode.
