The VMware Cloud Director administrator wants to make sure that the system is able to collect log bundles from all cells at once. How should the administrator accomplish this goal?
Correct Answer: D
Making sure the NFS server allows read-write access to the shared location by the root system account on each cell is the correct way to enable the collection of log bundles from all cells at once. This is because VMware Cloud Director uses the vmware-vcd-support script to collect host log information as well as Cloud Director logs, and this script requires the NFS server to have read-write access to the shared location by the root system account on each cell1. Installing vRealize Log Insight agent on each cell to redirect logs to a centralized location is not a valid option, as vRealize Log Insight is a separate product that does not integrate with VMware Cloud Director. Configuring a syslog server on each of the cells, and requesting the logs from the syslog server is not a feasible option, as it would require manual intervention and coordination to collect the logs from multiple sources. Mapping the log location on the primary cell to a shared folder on each of the other cells in the server group, ensuring they all have read/write rights on the primary is not asufficient option, as it does not address the NFS server configuration that is required for the vmware-vcd-support script to work properly.

Question 12
Which two additional parameters are taken into account when sizing a vRealize Operations cluster using the sizing tool? (Choose two.)
Correct Answer: A,C
According to the VMware vRealize Operations Install and Configure Guide1, the sizing tool is a web-based application that helps to estimate the required resources and configuration for a vRealize Operations cluster. The sizing tool takes into account various parameters,such as the number and type of objects to be monitored, the number of metrics and properties to be collected, the number of alerts and dashboards to be displayed, the number of users and concurrent sessions, and the desired availability and performance of the cluster. Two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool are: Time Series Data Retention: This parameter specifies the duration for which the collected metrics and properties are stored in the vRealize Operations database. The longer the retention period, the more disk space is required for the cluster nodes. The sizing tool allows the user to select the retention period from 1 month to 12 months, or to enter a custom value. Projected Growth: This parameter specifies the expected increase in the number and type of objects to be monitored over time. The higher the projected growth, the more resources are required for the cluster nodes. The sizing tool allows the user to select the projected growth from 0% to 100%, or to enter a custom value. Therefore, the correct answers are A. Time Series Data Retention and C. Projected Growth, as these are two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool.

Question 13
What is used to monitor third-party solutions from vRealize Operations?
Correct Answer: B
Question 14
Which statement accurately describes the characteristics of an alert notification?
Correct Answer: C
Question 15
Which two conditions must be met to allow an automated action to be triggered from an alert? (Choose two.)
Correct Answer: B,E
According to the VMware vRealize Operations User Guide1, an automated action is a predefined or custom action that can be executed automatically when an alert is triggered. An automated action can help to resolve or prevent the problem that caused the alert, or to notify the relevant stakeholders. To allow an automated action to be triggered from an alert, two conditions must be met: Within the active policy, the alert definition's automated setting must be set to enabled. This allows the alert definition to trigger automated actions when the alert criteria are met. By default, the automated setting is disabled for all alert definitions, and must be manually enabled by the administrator. The alert must have a recommendation attached to it. A recommendation is a suggested action that can help to resolve or prevent the problem that triggered the alert. A recommendation can include a link to a related topic in the documentation or an external URL. A recommendation can also be associated with an automated action, which can be executedby the system or by the user. An alert definition can have one or more recommendations, but only one of them can be associated with an automated action. Therefore, the correct answers are B. Within the active policy, the alert definition's automated setting must be set to enabled. and E. The alert must have a recommendation attached to it, as these are the two conditions that must be met to allow an automated action to be triggered from an alert.
