NEW QUESTION 16
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?
- A. Through the Service interface using the ifconfig command
- B. The IP address cannot be changed once it has been configured
- C. In the Unisphere Settings menu
- D. The IP address can only be changed using the UEMCLI
Answer: D
Explanation:
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.

NEW QUESTION 21
A system administrator wants to configure asynchronous replication on their Unity system. What is required before creating a replication session?
- A. A Sync Replication Management Port configured on each system.
A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems. - B. An IP-based replication interface on the same network as the destination system's replication interface.
A configured replication connection between the remote systems. - C. A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems. - D. A Sync Replication Management Port configured on each system.
An IP-based replication interface on the same network as the destination system's interface.
A configured replication connection between the remote systems.
Answer: D
Explanation:
Explanation/Reference:
Asynchronous remote replication requires a replication interface be created on each SP on the system.
For asynchronous replication, replication is performed over Ethernet interfaces configured on the system. On EMC Unity physical systems, the onboard 10GbE BaseT ports, CNA ports with Ethernet personality, or Ethernet ports located on I/O modules can be used for replication. In UnityVSA systems, any I/O port can be used for asynchronous replication.
NEW QUESTION 22
