A financial services company is using vRealize Operations to monitor a vSphere cluster dedicated to a high-frequency trading application. The administrator has created a custom group for all VMs in this application. They need to ensure that any VM in this group experiencing CPU co-stop values greater than 5% for more than 10 minutes generates a critical alert. Which sequence of components must be configured to meet this requirement?
Answer and explanation
Correct answer: B
The correct approach is to first define the condition to be monitored, which is done using a Symptom Definition. In this case, it would be a metric-based symptom for CPU|Co-stop (%) > 5. The Alert Definition then consumes this symptom and is configured with a wait cycle to ensure the condition persists for the required duration (e.g., a 5-minute collection interval with a wait cycle of 2 equals 10 minutes). Finally, a Notification Rule or Action is configured to handle the alert. Creating a Super Metric is unnecessary as co-stop is a standard metric. A View is for visualization, not for triggering alerts.
Question 2
Multiple answers
An administrator is creating a Super Metric to calculate the total provisioned vCPU for all powered-on VMs within a specific host cluster. Which two functions are essential for building the correct formula? (Select TWO)
Answer and explanation
Correct answers: B, D
The sum() function is required to aggregate the vCPU counts from all individual VMs into a single total value for the cluster.
The where() function is necessary to filter the VMs so that only those with a power state of 'poweredOn' are included in the summation, as per the requirement.
Question 3
A vRealize Operations administrator needs to provide a high-level summary dashboard for executive management. The dashboard must show the overall health of three key applications, the total monthly cost of the production environment, and the number of days remaining before the vSAN datastore runs out of capacity. Which combination of widgets is most suitable for these requirements?
Answer and explanation
Correct answer: C
The Scoreboard widget is ideal for showing the high-level health of a few key objects (the applications). The dedicated Cost widget is the best way to display monthly cost information. The Capacity widget is designed specifically to show metrics like 'Time Remaining' for resources such as datastores. This combination directly addresses all three executive requirements in a clear, concise manner.
Question 4
True or False: In a vRealize Operations cluster with Continuous Availability (CA) enabled, the cluster can withstand the failure of an entire fault domain (e.g., a data center rack) and continue data collection and analysis without interruption.
Answer and explanation
Correct answer: A
This statement is true. Continuous Availability (CA) is designed for disaster avoidance by stretching a single vRealize Operations cluster across two fault domains. It provides a higher level of availability than standard HA, allowing the cluster to remain operational even if one entire fault domain fails.
Question 5
A company has two data centers, DC1 and DC2, managed by a single vCenter Server. A vRealize Operations cluster is deployed in DC1. The network link between the data centers experiences high latency and occasional packet loss. Administrators report that data from ESXi hosts in DC2 is often missing or delayed in vRealize Operations. Which architectural change would be the most effective solution?
Answer and explanation
Correct answer: C
The primary role of a Remote Collector node is to gather data from remote sites and forward it to the analytics cluster. By placing a Remote Collector in DC2, it can collect data locally from the ESXi hosts and then send compressed, resilient data streams back to the main cluster in DC1. This architecture is specifically designed to handle high-latency, unreliable network links.
Question 6
An administrator is using the What-If Planning feature for a 'Migrate to Public Cloud' scenario to compare the cost of running a set of VMs on-premises versus in AWS. After running the scenario, the projected AWS cost is unexpectedly zero. What is the most likely cause for this result?
Answer and explanation
Correct answer: C
The What-If Planning feature relies on configured rate cards for public cloud providers to calculate costs. If the rates for AWS instance types, storage, and networking have not been downloaded and activated within vRealize Operations, the system has no pricing data to use for the calculation, resulting in a cost of zero.
Question 7
Company Background A large retail organization, RetailCorp, operates a significant e-commerce platform on a vSphere environment. This environment consists of 10 large clusters spread across two data centers, hosting approximately 5,000 virtual machines. They have recently deployed a vRealize Operations 8.6 Enterprise cluster to gain better insights into capacity, performance, and cost.
Current Situation Management has expressed concern about uncontrolled VM sprawl and inefficient resource utilization. The vRealize Operations team has been tasked with identifying and quantifying waste. Additionally, the finance department requires a showback model to make application owners aware of the cost of the infrastructure they consume. The current vROps policy is the default system policy, and no cost drivers have been configured.
Requirements
Identify all powered-off VMs that have been inactive for more than 60 days.
Identify all oversized VMs based on a conservative model that only considers usage over the past 30 days.
Implement a basic showback model based on server hardware and storage costs.
The solution must not impact the production monitoring alerts currently in place.
Problem Which set of actions should the vRealize Operations administrator take to meet all stated requirements without disrupting existing monitoring?
Answer and explanation
Correct answer: B
This is the best approach. Modifying the default policy is poor practice and could affect other settings. Creating a new, separate policy for these specific reclamation and analysis settings ensures that production monitoring alerts (governed by the default policy) are not affected. Applying this policy to the target group of VMs allows for the specific reclamation analysis required. Configuring the cost drivers is the necessary step to enable the showback model. This solution meets all requirements in a safe and scalable manner.
Question 8
Multiple answers
A vRealize Operations administrator is tasked with monitoring a custom Java application running on several Linux VMs. The goal is to monitor specific JMX MBean attributes from the application. Which steps are required to accomplish this? (Select THREE)
Answer and explanation
Correct answers: B, C, D
The Application Remote Collector is the component responsible for managing the Telegraf agents and discovering applications. It must be deployed and configured first.
The Telegraf agent is installed on the guest OS of the virtual machine to collect metrics from the application and send them to the ARC.
To monitor JMX attributes, the Jolokia input plugin for Telegraf must be configured. This involves specifying the MBean names and attributes to be collected from the Java application.
Question 9
An administrator observes that two different policies apply to a specific virtual machine: one is applied to the vSphere Cluster object (Priority: 100), and another is applied to a custom group containing the VM (Priority: 100). The policies have conflicting settings for the 'CPU|Usage|Anomalies' analysis setting. Which policy's setting will be enforced on the VM?
Answer and explanation
Correct answer: A
vRealize Operations uses a specific order of precedence for policy application. Policies applied to custom groups take precedence over policies applied to standard vSphere hierarchy groups (like Clusters or Folders), assuming the priorities are equal. Therefore, the setting from the policy applied to the custom group will be enforced.
Question 10
The 'Demand Model' for capacity analysis in vRealize Operations primarily bases its calculations on which set of metrics?
Answer and explanation
Correct answer: C
The Demand Model focuses on what resources the workloads have actually consumed over time. It analyzes historical usage data to project future needs, providing a more realistic view of capacity than the Allocation Model, which is based on provisioned resources.
