NEW QUESTION # 18
Question:
A backup array was able to achieve a 30:1 reduction by finding multiple copies of the same data. Which method was used in this scenario?
- A. Data replication
- B. Data compression
- C. Data encryption
- D. Data deduplication
Answer: D
Explanation:
Data deduplication is a technique that eliminates redundant copies of data, storing only unique instances.
When multiple copies of the same data are found, deduplication replaces them with references to a single stored copy, significantly reducing storage requirements.
* Data replication:Involves copying data to another location for redundancy, not reducing storage size.
* Data encryption:Secures data but doesn't affect storage size.
* Data compression:Reduces data size by encoding information more efficiently but doesn't eliminate duplicates.

NEW QUESTION # 19
Question:
An Ethernet switch has eight ports, and all ports must be operational for 24 hours from Monday through Friday. However, failures of Port 6 occur within the week as follows:
* Tuesday: 6 AM to 8 AM
* Thursday: 5 PM to 10 PM
* Friday: 7 AM to 9 AMWhat is the MTBF (Mean Time Between Failures) of Port 6?
- A. 40 hours
- B. 32 hours
- C. 30 hours
- D. 37 hours
Answer: A
Explanation:
To calculate the MTBF, we need to determine the total operational time and the number of failures.
* Total operational time (Monday to Friday):5 days × 24 hours = 120 hours
* Number of failures:3 (Tuesday, Thursday, Friday)
MTBF = Total operational time / Number of failures
MTBF = 120 hours / 3 = 40 hours

NEW QUESTION # 25
Question:
What is a read miss in cache operations?
- A. Fetching requested data that is already in cache
- B. Deleting data from the cache
- C. Fetching data that is not in cache
- D. Writing data to the cache
Answer: C
Explanation:
Aread missoccurs when the data requested by the host isnotavailable in the cache. As a result, the storage system must fetch the data from the slower disk storage (back-end), leading to higher latency.
* Cache hit:Data is already in cache # faster response.
* Cache miss (read miss):Data not in cache # fetched from the disk.

NEW QUESTION # 27
Question:
What method does FCIP use to transport Fibre Channel SAN data?
- A. FCIP encapsulates and tunnels FC SAN data over Ethernet networks.
- B. FCIP splits LAN and FC SAN data and tunnels FC SAN data over Ethernet networks.
- C. FCIP separates LAN and FC SAN data and tunnels FC SAN data over IP networks.
- D. FCIP encapsulates and tunnels FC SAN data over IP networks.
Answer: D
Explanation:
FCIP (Fibre Channel over IP) is a protocol used to connect Fibre Channel SANs across geographically dispersed locations over IP networks. It does this byencapsulating Fibre Channel frames into IP packets (Layer 3). This allows FC SAN traffic to be transmitted across IP-based WANs.
* Ethernet networks(Layer 2) are not involved in the FCIP encapsulation process directly because FCIP uses IP packets.
* Splitting LAN/SAN datais not the method used; FCIP encapsulatesall FC frames.
* Separating LAN and SAN dataalso does not describe the tunneling function.

NEW QUESTION # 30
Question:
A customer uses FCIP to connect local and remote FC SANs. The remote SAN is replicated to and used to store daily backup data. Latency over the IP WAN increases to unacceptable levels during peak replication periods. No other data transfer services using the WAN experience the same latency problem.
What is the likely cause of the data replication performance issue?
- A. Ethernet frame segmentation
- B. FCIP gateway FC ports set to TE_Port mode
- C. FCIP gateway FC ports set to EX_Port mode
- D. IP packet segmentation
Answer: D
Explanation:
IP packet segmentationcan cause replication performance issues over the WAN.
Since FCIP tunnels FC frames over IP networks, if the IP packet size exceeds the MTU, packets are fragmented and reassembled, increasing latency.
* TE_Port modeis used for trunking, not related to packet fragmentation.
* EX_Port modeis used for inter-switch connectivity (FCR).
* Ethernet frame segmentationis not relevant in FCIP tunneling.

- D. To monitor the health of the backup infrastructure
Answer: C
Explanation:
Astorage nodeis a component in a backup architecture that handles the actualdata movementduring the backup process:
Itorganizesthe backup data stream.
Itwritesthe data to the backup target (disk, tape, or cloud).
It does not manage policies or schedules (that's the role of the backup server or management console).
* Option A:Monitoring is done by the backup server or management tools.
* Option C:Backup management (scheduling, policies) is also handled by the backup server.
* Option D:Deduplication may be part of the process but is not theprimary roleof a storage node.
