A storage administrator wants to configure a Unity system to log system events to a remote log server. In order to allow access to the log server, which port should the administrator ensure is not blocked by the firewall?
Answer(s): A
The storage system supports logging user/audit messages to a remote host. By default, the storage system transfers log information on port 514 using UDP.

A Unity system LUN has a daily snapshot schedule with a Retention Policy of seven days. A hardware failure results in a double fault of the LUN.Which snapshot behavior will be experienced?
Answer(s): D

What describes multiple LUN snapshots?
Only a single snapshot per LUN can be attached at any given time, and must be detached prior to attaching another snapshot of the same LUN.
What is the maximum number of LUN snapshots that are supported by Unity?
Answer(s): C

At which stage in the Unity power up sequence would the Storage Processor enter Service mode upon detecting an error?
Note: Boot counters are a troubleshooting mechanism that is designed into the Unity architecture to help pinpoint the specific cause of software or hardware events during the boot sequence. If the Unity system detects a problem with software or hardware components, its corresponding Boot Counter is incremented. If a counter reaches a predefined threshold, the SP boots into Service Mode during its next boot cycle.

q252: dns poisoning is the correct answer, not locator redirection. beaconing is detected from a host. this indicates that the system has been infected with malware, which could be the source of local dns poisoning. location redirection works by either embedding the redirection in the original websites code or having a user click on a url that has an embedded redirect. since users at a different office are not getting redirected, it isnt an embedded redirection on the original website and since the user is manually typing in the url and not clicking a link, it isnt a modified link.
