質問 # 43
Which of the following transport protocols are supported by scheduled NIOS Grid Backup? (Select all that apply.)

A. HTTPS
B. SCP
C. FTP
D. SFTP

正解：A、B、C、D

解説：
Comprehensive and Detailed In-Depth Explanation:NIOS Grid Backup allows scheduled exports of the configuration database (DNS, DHCP, Grid settings) to an external server. Supported protocols ensure flexibility and security:
* A (SFTP):Secure File Transfer Protocol (SSH-based) is supported for encrypted backups to remote servers (port 22). Widely used for secure transfers. Correct.
* B (SCP):Secure Copy Protocol (also SSH-based) is supported, offering a simple, secure file transfer option (port 22). Correct.
* C (FTP):File Transfer Protocol (unencrypted, port 21) is supported for legacy systems, though less secure. Correct.
* D (HTTPS):Web-based secure transfer (port 443) is supported, allowing backups to HTTP servers with SSL/TLS encryption. Correct.
* Setup:In Grid Manager (Grid > Grid Manager > Backup), you configure the protocol, server IP, and credentials.
* Practical Example:In an INE lab, you'd schedule a backup using SFTP to a remote server, test restoration, and troubleshoot connectivity issues, reinforcing Grid deployment skills.
* Note:All four are explicitly supported per NIOS documentation, making this a comprehensive list.

質問 # 44
A customer has the following Grid: Grid Master HA pair, three HA Grid Members, one single Grid Member.
The customer has defined custom Upgrade Groups based on the physical location of the appliances. After the administrator clicks Upgrade, which node will go through the upgrade process first?

A. All of the Member passive nodes
B. Grid Master active node
C. Grid Master passive node
D. Depends on the configuration of Upgrade Groups

正解：D

解説：
Comprehensive and Detailed In-Depth Explanation:In NIOS, the upgrade process for a Grid can be customized usingUpgrade Groups, which allow administrators to define the order and timing of upgrades for Grid members based on criteria like location or role. By default, the Grid Master (active node) upgrades last to ensure continuity, and passive nodes in HA pairs often upgrade before active nodes. However, when custom Upgrade Groups are defined (as in this scenario, based on physical location), the upgrade sequence follows the administrator's configuration rather than a fixed rule. Thus, the first node to upgrade depends entirely on how the Upgrade Groups are prioritized in the upgrade schedule. This flexibility is a focus of the INE course's Grid deployment section.References:Infoblox NIOS Administrator Guide - Software Upgrades; INE Course Objective: NIOS DDI Grid Deployment.

質問 # 45
What command clears the NIOS database but preserves system logs and other licensed features such as reporting?

A. reset all
B. reset database
C. reset config
D. reset all licenses

正解：B

解説：
Comprehensive and Detailed In-Depth Explanation:Clearing the NIOS database requires a precise CLI command:
* B (reset database):Wipes DNS zones, DHCP leases, and Grid membership, but retains:
* System logs (e.g., syslog, infoblox.log).
* Licenses (e.g., reporting, DNSSEC).
* Network settings (IP, hostname). Correct.
* A:"reset all" isn't valid (see Q28). Incorrect.
* C:"reset config" isn't a command-closest is set factory, which wipes everything. Incorrect.
* D:reset all licenses clears licenses only, not the database. Incorrect.
* Practical Example:In an INE lab, you'd run reset database, verify logs persist via show log, and reconfigure, testing Grid recovery.References:Infoblox NIOS CLI Reference Guide - Reset Commands; INE Course Content: NIOS DDI Grid Troubleshooting.

質問 # 46
You are asked to configure DHCPv4 failover on the Grid. Which of the following do you need for it to function correctly? (Select all that apply.)

A. DHCP members are located in the same subnet
B. DHCP members are directly connected via crossover network cables
C. TCP port 647 is open between DHCP members
D. DHCP relays are configured to relay to DHCP members simultaneously

正解：C、D

解説：
Comprehensive and Detailed In-Depth Explanation:DHCPv4 Failover requirements:
* C:TCP 647 is the failover sync port-must be open for lease coordination. Correct.
* D:Relays must send requests to both peers (e.g., via IP helper addresses) for load balancing
/redundancy. Correct.
* A:Crossover cables aren't required-standard network connectivity suffices. Incorrect.
* B:Same subnet isn't mandatory-peers can be remote if routable. Incorrect.
* Practical Example:In an INE lab, ensure port 647 is open, configure relays, test failover, and troubleshoot sync issues.References:Infoblox NIOS Administrator Guide - DHCP Failover Setup; INE Course Content: NIOS DDI DHCP Troubleshooting.

質問 # 47
What configuration can a Grid Master be? (Select all that apply.)

A. A High Availability pair
B. A Grid Candidate Failover node
C. A virtual appliance
D. A single appliance

正解：A、C、D

解説：
Comprehensive and Detailed In-Depth Explanation:The Grid Master (GM) manages the NIOS Grid's database and coordination. Its possible configurations are:
* A (Virtual Appliance):A GM can be a vNIOS instance (e.g., on VMware), fully supported for virtualized deployments. Correct.
* B (Single Appliance):A standalone physical NIOS appliance (e.g., IB-4000) can serve as GM.
Common in smaller Grids. Correct.
* C (High Availability Pair):A GM can be an HA pair (two appliances sharing a VIP), ensuring redundancy. Correct.
* D (Grid Candidate Failover Node):Misnomer-Grid Master Candidate (GMC) is a separate role, not the GM itself. A GMC can be promoted to GM, but it's not a GM configuration. Incorrect.
* Setup:Configured via Grid Manager (Grid > Grid Properties).
* Practical Example:In an INE lab, you'd deploy a vNIOS GM, test HA failover, and troubleshoot sync, exploring deployment options.References:Infoblox NIOS Administrator Guide - Grid Master Setup; INE Course Objective: NIOS DDI Grid Deployment.
