Question 1

What can an administrator do with an Option Filter in NIOS?

A

Match on any DHCP options provided by the client

B

Match on any DHCP options provided by the server

C

Match only vendor-specific options such as Option 60

D

Match only on device types

Correct Answer: A

Explanation:

Comprehensive and Detailed In-Depth

In NIOS, DHCP Option Filters allow administrators to define rules for matching DHCP client requests

based on the options they send in their DHCP packets. These filters are highly flexible and can match

any DHCP option provided by the client, such as Option 55 (Parameter Request List), Option 60

(Vendor Class Identifier), or custom options. This enables precise DHCP policy enforcement, like

assigning specific IP ranges or options to certain devices. Option B is incorrect because filters apply to

client requests, not server responses. Option C is too narrow—while Option 60 is common, filters

aren’t limited to vendor-specific options. Option D is vague and incorrect; device type matching is a

subset of option matching. The INE course covers DHCP troubleshooting, including filter

configuration.

Question 2

A Grid member in a DHCP Failover pair is in the PARTNER-DOWN state. What does this mean?

A

The member has lost contact with its peer

B

An administrator put the member in this state to indicate the member's peer is down

C

An administrator put the member in this state to indicate the member is down and

the member's peer will take over D

This member is malfunctioning and the member's peer must take over assignments

Correct Answer: B

Explanation:

Comprehensive and Detailed In-Depth Explanation: 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. References: Infoblox NIOS Administrator Guide – DHCP Failover States; INE Course Content: NIOS DDI DHCP Troubleshooting.

The Infoblox WAPI/RESTful API requires the administrator to use the Perl programming language.

Correct Answer: B

Comprehensive and Detailed In-Depth

The Infoblox Web API (WAPI) is a RESTful API that allows administrators to interact with the NIOS

system programmatically for tasks like managing DNS records, DHCP leases, and Grid configurations.

Contrary to requiring Perl, WAPI is language-agnostic—it uses HTTP-based requests (GET, POST, PUT,

DELETE) and returns data in JSON format. While Infoblox provides sample scripts in Perl (and

historically supported a Perl API), administrators can use any programming language (e.g., Python,

Java, or even tools like cURL) that supports HTTP requests. The misconception might stem from older

documentation emphasizing Perl examples, but the INE course, focusing on advanced NIOS

management, clarifies that WAPI is not tied to Perl.
