QuestionQ1

Security and Management

An Ethernet switch has eight ports, and every port must operate for 24 hours per day from Monday through Friday. However, Port 6 experiences the following failures during the week:

  • Tuesday: 6 AM to 8 AM
  • Thursday: 5 PM to 10 PM
  • Friday: 7 AM to 9 AM

What is the MTBF for Port 6?

Explanation

MTBF is calculated as total operating time divided by the number of failures. Over 120 scheduled hours, Port 6 has 9 hours of downtime, leaving 111 operating hours. Dividing 111 hours by 3 failures gives an MTBF of 37 hours.

QuestionQ3

Backup, Archive, and Replication

A company needs a backup solution that reduces IT management overhead while providing scalability and flexibility.

Which type of backup solution would satisfy these requirements?

Explanation

Cloud-based backup reduces the need to manage on-premises backup infrastructure and can scale storage capacity and services as needs change.

QuestionQ4

Storage Systems

A company is encountering slow write performance on its RAID 6 array.

What is the most likely reason for this performance bottleneck?

Explanation

RAID 6 writes incur a dual-parity write penalty because data updates require calculating and writing two parity blocks, often along with read-modify-write operations. This additional work reduces write performance.

QuestionQ5

Storage Systems

What process automatically moves infrequently accessed data to a more cost-effective storage medium?

Explanation

Storage tiering automatically relocates less frequently accessed data to lower-cost storage tiers while keeping more active data on higher-performance storage.
