Questions # 1:

A storage administrator is tasked with creating a DR solution for block and file storage resources. The company has multiple regional and international sites containing a mix of physical and virtual Dell EMC Unity systems.

What are considerations for the storage administrator in creating the DR solution?

Options:

Synchronous remote replication should be restricted to within 100 km between sites to keep latency below 10 msBlock storage resources can be replicated synchronously and asynchronously

Asynchronous replication ensures zero data loss the remote replica in disaster conditionsBlock storage resources can be replicated synchronously and asynchronously

Asynchronous replication over long-distance does not impact latencyAsynchronous replication ensures zero data loss to the remote replica in disaster conditions

Synchronous remote replication should be restricted to within 100 km between sites to keep latency below 10 msFile and block storage resources can be replicated synchronously and asynchronously

Questions # 4:

What remote service is required to enable Remote Logging in the Dell EMC Unity XT system?

Options:

SNMPv3

Syslog

SNMPv2

Unisphere agent

Answer

Explanation

Before configuring remote logging for a storage system, you must configure each remote system to receive logging messages from the storage system. A root/administrator on the receiving computer can configure the remote syslog server or rsyslog server to receive log information by editing the syslog server or rsyslog server configuration file (syslogng.conf or rsyslog.conf) on the remote system.
