質問 # 30
A storage administrator is configuring a trunk between two Brocade fibre channel switches, but the trunk fails to initialize. What should the administrator do to solve this issue?
正解：A
解説：
In Brocade B-series Fibre Channel fabrics, ISL (Inter-Switch Link) Trunking is an optional licensed feature that allows multiple physical links between two switches to be aggregated into a single logical high- bandwidth pipe. While two switches can connect via a standard ISL without a specific license, the "Trunking" capability-which enables frame-level load balancing across those links-requires the ISL Trunking license to be installed and active on both participating switches.
According to the Brocade Fabric OS Administration Guide, if the license is missing or expired, the ports will function as individual ISLs rather than a unified trunk. This leads to the "failure to initialize" as a trunk, where the ports might stay in a "Master" or "Active" state individually but never form a "Trunk port" relationship. A common troubleshooting step after installing the license is to portdisable and then portenable the affected ports to force the fabric to re-negotiate the trunking capability.
Options B and D are technically incorrect because trunking specifically requires E_ports (Expansion Ports) used for switch-to-switch connectivity; converting them to F_ports (Fabric ports) would make them intended for end-device (host/storage) connectivity, which does not support ISL trunking. Furthermore, for a trunk to form, the ports must be within the same physical port group on the ASIC (e.g., ports 0-7 or 8-15 on many fixed-port switches), making Option D the opposite of what is required for success. By ensuring the Trunking license is present, the administrator enables the hardware and software to utilize the Exchange- Based Routing (EBR) or frame-based trunking protocols necessary for the solution.

A customer has a diverse NoSQL big data and data analytics workload implementation. This workload runs on bare-metal servers to achieve the most efficient performance. The customer requires a new storage solution to meet their growing data needs. Which solution will be best for the customer?
正解：C
解説：
For workloads like NoSQL databases (e.g., MongoDB, Cassandra), Big Data analytics (e.g., Hadoop, Spark), and high-throughput data lakes, the primary performance bottleneck is often the latency and bandwidth between the compute and the storage media. When a customer specifies they are running on bare- metal servers to achieve "most efficient performance," they are looking for a solution that minimizes the overhead of hypervisors and provides direct, high-speed access to storage.
The HPE Alletra Storage Server 4000 series, and specifically the Alletra 4110, is purposefully engineered for this "Data-First" server-based storage market. The Alletra 4110 is a 1U, all-NVMe ultra-dense storage server that supports dual 4th or 5th Gen Intel Xeon Scalable processors and PCIe Gen5 throughput. Unlike traditional storage arrays that connect via a SAN, the Alletra 4110 functions as high-performance Software- Defined Storage (SDS) infrastructure. It is designed to run the application and the data storage on the same high-density nodes, or to act as a high-speed storage tier for bare-metal clusters.
Other options are less suitable for this specific "bare-metal NoSQL" requirement:
* HPE SimpliVity (B) is a Hyperconverged Infrastructure (HCI) solution that is inherently tied to a hypervisor (VMware or Hyper-V), which contradicts the customer's bare-metal requirement.
* HPE Alletra dHCI (C) is a disaggregated HCI solution that automates a SAN environment but is also centered around VMware virtualization.
* HPE GreenLake for Private Cloud Business Edition (A) is a service-oriented offering primarily for managing virtualized private clouds.
The Alletra 4110 provides the massive I/O throughput (up to 315 GB/s of PCIe Gen5 bandwidth to SSDs) and the low-latency NVMe performance that NoSQL and analytics workloads demand, making it the superior architectural choice for bare-metal, data-intensive environments.
質問 # 32
A customer wants predictive analytics to identify storage issues before users notice them. Which HPE feature delivers this capability?
正解：C
解説：
HPE InfoSight uses AI-driven predictive analytics to identify anomalies, recommend remediation, and prevent outages proactively. iLO manages servers, SSH provides remote access, and REST APIs allow automation but do not provide predictive intelligence.
質問 # 33
An administrator has implemented automatic switchover (ASO) with Peer Persistence on a pair of HPE Alletra 6000 storage arrays. Which statement is correct regarding the ASO feature?
正解：B
解説：
HPE Peer Persistence for the Alletra 6000 (and Nimble) provides synchronous replication and automatic transparent failover (ATF) using the Automatic Switchover (ASO) feature. This process is governed by a Quorum Witness that monitors the health of both arrays in a group. A fundamental design principle of HPE high-availability storage is to prevent "flapping"--a condition where a workload repeatedly bounces between two sites due to an unstable connection.
Consequently, the ASO process is designed to be unidirectional and sticky. When a primary site failure occurs and the Quorum Witness authorizes an automatic switchover, the secondary array becomes the "Upstream" (active) array and begins serving I/O. Once the original primary site is restored and the replication link is re-established, the arrays will automatically begin a resynchronization to ensure data consistency. However, even after the data is fully synced, the system will not automatically move the workload back to the original array. The administrator must perform a manual handover to return the volume collection to its preferred primary site.
質問 # 34
An HPE customer purchased an HPE B-Series SN7000B SAN fabric switch. QoS is currently not enabled. Which two statements are correct regarding buffer-to-buffer (BB) credits and the operation of the switch? (Choose two.)
正解：A、D
解説：
The HPE B-Series SN7000B is a high-performance Director based on Brocade Gen 7 (G7) technology. Buffer-to-Buffer (BB) credits are the fundamental flow-control mechanism used in Fibre Channel to prevent frame loss and manage congestion.
Statement D is a foundational principle of SAN architecture: BB credits are based on link speed and frame size. In an FC fabric, the number of credits required to "fill the pipe" (keep data moving without waiting for acknowledgments) is a direct function of the Round Trip Time (RTT), which is determined by the physical distance, the speed of the link (e.g., 64Gb/s vs 32Gb/s), and the size of the frames being sent (typically 2KB). As link speeds increase, more buffer credits are required to maintain full throughput over the same distance.
Statement C reflects a specific technical default in the Brocade Fabric OS (FOS) for Gen 7 hardware. To ensure that ports can initialize and handle basic traffic immediately upon being enabled, the switch reserves a default number of credits from the ASIC's global buffer pool. For user ports on these high- density blades, the system reserves eight buffer credits per port, regardless of whether the port is currently online or offline. This reservation ensures that the port has the minimum resources necessary to complete a fabric login (FLOGI) or negotiate a link without competing for pool resources.
