DELL-EMC E20-594 Specialist Implementation Engineer Avamar Exam Free Practice Test — 30 Questions

Question 1

In a virtualized environment using Avamar Virtual Edition, a company is planning to back up a total of 10 TB of data. They have a retention policy that requires keeping backups for 30 days. The company has a daily incremental backup strategy, where each incremental backup captures approximately 5% of the total data. If the company also performs a full backup every 7 days, how much total storage space will be required for backups over the 30-day retention period, assuming that the incremental backups do not change the data already backed up?

Accepted Answer

15 TB

Question 2

In a scenario where a company is utilizing Avamar for data backup, they notice a significant increase in backup window times during peak operational hours. The IT team is tasked with optimizing the backup performance without compromising data integrity. Which of the following strategies would most effectively enhance backup performance while considering the impact on system resources?

Accepted Answer

Implementing a backup schedule that aligns with off-peak hours to reduce resource contention.

Question 3

In a data protection environment using Dell EMC Avamar, an administrator is tasked with configuring alerts and notifications for backup jobs. The administrator wants to ensure that they receive notifications for both successful and failed backup jobs, but only for jobs that exceed a certain duration threshold. If a backup job takes longer than 120 minutes, the administrator should receive an alert. Given that the average duration of backup jobs is normally distributed with a mean of 90 minutes and a standard deviation of 15 minutes, what is the probability that a randomly selected backup job will exceed the 120-minute threshold?

Accepted Answer

Approximately 0.1587

Question 4

In a scenario where a company is experiencing intermittent failures in its backup processes, the IT team decides to analyze the Avamar log files to identify the root cause. They notice a pattern of errors related to network connectivity issues during specific time frames. Given that the log files contain timestamps, error codes, and descriptions, how should the team approach the analysis to effectively diagnose the problem?

Accepted Answer

Correlate the timestamps of the errors with network performance metrics to identify potential outages or slowdowns during those periods.

Question 5

In a data protection environment utilizing Avamar, the Metadata Store plays a crucial role in managing backup and restore operations. Consider a scenario where a company has implemented a multi-tiered backup strategy, involving both full and incremental backups.
