The HCP back-end network is specifically designed to handle internal cluster traffic such as inter-node communication. This traffic type is critical for maintaining cluster synchronization, managing metadata, balancing loads, and ensuring consistent data storage and retrieval across the nodes in the cluster. Other types of traffic, like BMC access (A), tenant management console access (B), and replication traffic (D), typically occur over separate management or front-end networks. The "HCP Network Configuration and Management Guide" provides detailedinformation on network segmentation and the roles of different network types in an HCP environment.
Question 2
You are performing an online upgrade of an HCP G10 and the upgrade fails.
Which log is available to assist troubleshooting?
Options:
A.
Syslog
B.
Rollback logs
C.
Simple Trace log
D.
Arc-deploy logs
Answer:
D
Explanation:
When performing an online upgrade of an HCP G10 and the upgrade fails, theArc-deploy logsare the relevant logs available to assist with troubleshooting. These logs contain detailed information about the deployment and upgrade processes, including errors or issues encountered during the upgrade. Accessing these logs allows administrators to diagnose the failure and take corrective actions.
The Arc-deploy logs are essential for understanding the sequence of events and identifying the exact step or component that caused the failure during an online upgrade of the HCP G10.
Question 3
Which two statements are true about the HCP G10 SSD option? (Choose two.)
Options:
A.
Two SSD disks are installed at the rear of the server
B.
Six SSD disks are installed in the front of the server
C.
Software RAID1 is used to mirror the disks
D.
Hardware RAID6 is used to ensure fault tolerance.
Answer:
A, C
Explanation:
For the HCP G10 SSD option:
Two SSD disks are installed at the rear of the server (A):This is correct. The SSDs in the HCP G10 server are typically installed at the rear of the server to provide fast access to critical system data, such as metadata and indexes.
Software RAID1 is used to mirror the disks (C):This statement is also correct. Software RAID1 provides mirroring of the SSD disks, ensuring redundancy and data protection in case of a disk failure. RAID1 is chosen for its simplicity and reliability in providing redundancy without requiring additional hardware. Details can be found in the "HCP G10 Hardware Configuration and Maintenance Guide."
