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.)
Comprehensive and Detailed In-Depth
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.
A Grid member in a DHCP Failover pair is in the PARTNER-DOWN state. What does this mean?
Comprehensive and Detailed In-Depth
PARTNER-DOWN in DHCP Failover:
B: Admin manually sets this state (Grid > DHCP > Failover > Edit) to signal the peer is down (e.g., powered off), giving the member full pool control. Correct.
A: Loss of contact is COMMUNICATIONS-INTERRUPTED---PARTNER-DOWN is deliberate. Incorrect.
C: Indicates the member is down---opposite of intent. Incorrect.
D: Malfunction implies automatic state---PARTNER-DOWN is manual. Incorrect.
Practical Example: In an INE lab, set PARTNER-DOWN, verify full lease control, and troubleshoot sync resumption.
How can an administrator access the NIOS Online Documentation through the Grid Manager UI?
Comprehensive and Detailed In-Depth
NIOS Online Documentation is accessible via Grid Manager:
D: Help > Documentation > NIOS Online Documentation opens a browser to the latest NIOS docs (e.g., Admin Guide) hosted online or locally. Correct.
A: Logs > Download is for syslog/support bundles, not docs. Incorrect.
B: Tools > Support Bundle is diagnostics, not documentation. Incorrect.
C: No ''Download Admin guide'' option exists under Tools. Incorrect.
Practical Example: In an INE lab, you'd access docs via Help to troubleshoot a Grid join issue, testing resource navigation.
A superuser can change the password on another admin account.
Comprehensive and Detailed In-Depth
In NIOS, a superuser is an admin with unrestricted permissions across the Grid, including user management. Here's the breakdown:
Superuser Role: Defined in Grid Manager (Administration > Administrators), superusers have full read/write access to all objects and settings, including admin accounts.
Password Change: A superuser can navigate to Administration > Administrators, select another admin account (e.g., 'user1'), and modify its password, overriding any restrictions on that account.
Why True: This is a built-in capability to ensure ultimate control, useful for scenarios like account recovery or security enforcement. No restrictions apply to superusers for this action.
Practical Example: In an INE troubleshooting lab, a superuser might reset a locked-out admin's password to regain Grid access, testing authentication policies.
Contrast: Regular admins with limited permissions can't modify others' accounts unless explicitly granted.
How many IP addresses are required to configure a High Availability (HA) pair?
Comprehensive and Detailed In-Depth
An HA pair in NIOS requires:
1. Virtual IP (VIP): Shared address for services (e.g., 192.168.1.100).
2. Active Node IP: Physical address (e.g., 192.168.1.101).
3. Passive Node IP: Physical address (e.g., 192.168.1.102).
Total: 3 IPs.
Options:
A: 2 IPs insufficient---misses individual node IPs. Incorrect.
B: 3 IPs match HA design (VIP + 2 nodes). Correct.
C/D: Extra IPs (e.g., MGMT) are optional, not required. Incorrect.
Practical Example: In an INE lab, configure VIP 10.0.0.1, active 10.0.0.2, passive 10.0.0.3, test failover, and troubleshoot VRRP.
