A system administrator wants to configure asynchronous replication on their Unity system. What is required before creating a replication session?
A.
A Fibre Channel connection configured between the remote systems. A configured replication connection between the remote systems.
B.
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.
C.
An IP-based replication interface on the same network as the destination system's replication interface. 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.
Suggested Answer:D🗳️
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.
i will also say C - as For synchronous block replication, you must create the Synchronous Replication Management Port
To create a replication interface, click the Create Interface button, shown as a + sign in the Interfaces page. Once selected, the Create Interface wizard appears, which is shown in Figure 5. For synchronous block replication, you must create the Synchronous Replication Management Ports on the system, which are used for management connectivity between the source and destination system. In the Ethernet Port drop down list, select Sync Replication Management Port. The status of the ports will be shown in parenthesis. Both system management ports, also used for Unisphere management, will need to be cabled to the network for these links to work properly.
Next, configure an IP address for SPA and SPB to be used for synchronous replication management. Note that VLAN tagging is not supported on these interfaces. Once done, click OK
This link goes no where and I cannot find a reference to a Sync Management Port feature as described in (https://www.dellemc.com/resources/en-us/asset/white-papers/products/storage/h15088-dell_emc_unity-replication_technologies.pdf), so the answer is likely C
