Which of the following statements regarding the high reliability of Huawei OceanStor V3 are true? (Multiple Choice)

• A.Huawei OceanStor V3 uses RAID 2.0+ (underlying virtualization technology) to automatically balance loads among disks.
• B.The Huawei OceanStor V3 components use the 1+ 1 redundancy design and work inactive-active mode.
• C.Huawei OceanStor V3 provides the backup battery unit (BBU) module, which can provide power to the controller enclosure in the event of a power failure. This ensures that Huawei OceanStor V3 is able to write cache data into the built-in disks on the controller to prevent data loss.
• D.Huawei OceanStor V3 uses the disk precopy technology. By routinely checking the risk status, Huawei OceanStor V3 proactively migrates the data on a disk when detecting a fault risk on the disk, effectively reducing the data loss risks.

DCN refers to interconnection between two DC Ns for cross-DC service communication and migration.

• A.True
• B.False

Which of the following statements regarding how to use SLA management of the eSight are true? (Multiple Choice)

• A.Compliance degree alarm: An alarm is generated if the compliance degree is lower than expected.
• B.Compliance degree: The SLA compliance degree can be calculated based on the indicators, thresholds, and weights, and the related information is displayed in graphs.
• C.Indicator alarm: Users can define the SLA monitoring threshold based on requirements. When the threshold is exceeded, an alarm is generated.
• D.Periodic monitoring: Periodic monitoring can be performed flexibly based on the dates specified by users.
• E.Measurement capability: Multiple indicators (such as latency, jitter, and packet loss rate) often testcases (such as ICMP Echo, UDP Echo, TCP Connect, HTTP, DNS, and ICMP Jitter) can be measured.

Block storage is a mode of storing data by block, and a block refers to the sector group on the underlying disk.
Which of the following statements regarding block storage is true?

• A.Block storage can meet the requirement of a system containing thousands of CPUs.
• B.Block storage has good scalability and manageability.
• C.Block storage can provide high-performance random l/O and data throughput.
• D.Storage devices are cost-effective.

Which of the following statements regarding Huawei NG FW series firewalls are true? (Multiple Choice)

• A.Huawei NG FW series firewalls support policy-based traffic learning and awareness of the overall network service environment. They perform intelligent analysis based on services and security risks, and then automatically generate policy suggestions.
• B.Huawei NG FW series firewalls provide the policy simplification method, and can automatically find redundant and ineffective policies in the system.
• C.Huawei NG FW series firewalls can implement fast deployment.
• D.Huawei NG FW series firewalls provide open APls, supporting programmable management.
