This 200-901 practice question tests your understanding of network fundamentals. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer needs to send a diagnostic request to a network device to verify if it supports a specific MIB object. Which protocol and operation should be used?
ICMP ping
Why wrong: Ping tests connectivity, not MIB support.
HTTP GET
Why wrong: HTTP is not used for MIB access.
SNMP SET
Why wrong: SET is for writing, not reading.
NETCONF get-config
Why wrong: NETCONF is for YANG-modeled data, not SNMP MIBs.
SNMP GET
GET retrieves the value of a MIB object.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SNMP GET
SNMP GET is the correct operation to retrieve the value of a specific MIB object from a network device. It sends a diagnostic request to verify if the device supports that object by checking whether a valid response is returned. This is the standard SNMP operation for reading a single managed object's value.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
ICMP ping
Why it's wrong here
Ping tests connectivity, not MIB support.
HTTP GET
Why it's wrong here
HTTP is not used for MIB access.
SNMP SET
Why it's wrong here
SET is for writing, not reading.
NETCONF get-config
Why it's wrong here
NETCONF is for YANG-modeled data, not SNMP MIBs.
SNMP GET
Why this is correct
GET retrieves the value of a MIB object.

Common exam traps
Cisco often tests the distinction between SNMP GET (read) and SNMP SET (write), and candidates may confuse them or think SET can verify support, but SET only modifies values and requires the object to already exist.
Detailed technical explanation
SNMP GET uses UDP port 161 and sends a GetRequest-PDU to the agent, which responds with a GetResponse-PDU containing the requested OID's value. If the MIB object is not supported, the agent returns a 'noSuchObject' error in the response. This mechanism is defined in RFC 3416 and is fundamental for network monitoring and diagnostics.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
