NEW QUESTION 128
What is the minimum and maximum recovery point objectives (RPO) configurable when using Unity native asynchronous replication?

Minimum= 5 minutesMaximum= 24 hours

Minimum= 5 minutesMaximum= 48 hours

Minimum= 1 minuteMaximum= 24 hours

Minimum= 1 minuteMaximum= 48 hours

Explanation
Recovery Point Objective (RPO) is an industry accepted term that indicates the acceptable amount of data, measured in units of time, that may be lost in a failure. When you set up an asynchronous replication session, you can configure automatic synchronization based on the RPO. You can specify an RPO from a minimum of
5 minutes up to a maximum of 1440 minutes (24 hours).

NEW QUESTION 141
A system administrator has configured a system using the Initial Configuration wizard. After completing the wizard, the administrator discovers that an incorrect IP address has been assigned to the Unity system.
How can the IP address be changed?

The IP address cannot be changed once it has been configured

Through the Service interface using the ifconfig command

In the Unisphere Settings menu

The IP address can only be changed using the UEMCLI

Explanation/Reference:
The svc_initial_config UEMCLI command sets up initial system configuration. It configures a management IP address when the Connection Utility (CU) is not available on the network. If an address is set, this command can also change the management IPv4 and IPv6 configuration mode. It attempts to configure the system with the given friendly name and/or network parameters.
Note: The Unisphere CLI (UEMCLI) is a tool that provides us with the CLI access to perform the same actions as one would on the Unisphere web interface.
