The correct answer is that OIDs are always numeric and follow a hierarchical tree structure. This is because the Management Information Base (MIB) organizes every managed object into a standardized, inverted-tree hierarchy, where each node is assigned a unique numeric Object Identifier (OID), such as 1.3.6.1.2.1.1.1.0 for sysDescr. The MIB defines not only the structure of these objects but also the allowed operations—like get, set, and GetBulk—though GetBulk is only supported in SNMPv2c and SNMPv3, not SNMPv1, a distinction frequently tested on the ENCOR 350-401 exam. A common trap is confusing the human-readable MIB name with the underlying numeric OID; remember that the MIB is the database, while the OID is the exact numeric address. For a quick memory tip, think of the OID as a phone number for a device’s data—always digits, never letters, and arranged in a strict hierarchy from root to leaf.
350-401 SNMP and Syslog Practice Question
This 350-401 practice question tests your understanding of snmp and syslog. 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.
Which two statements about SNMP MIB objects and OIDs are true? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The MIB defines the structure of managed objects and their OIDs.
MIB (Management Information Base) is a hierarchical database of managed objects. Each object is identified by an OID (Object Identifier). OIDs are structured as a tree; for example, 1.3.6.1.2.1.1.1.0 is the sysDescr OID. The MIB defines the structure and allowed operations (get, set, etc.) for each object. SNMPv2c and SNMPv3 support GetBulk, which retrieves large tables efficiently. SNMPv1 does not support GetBulk.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The MIB defines the structure of managed objects and their OIDs.
Why this is correct
Correct: The MIB is a database that defines the structure and OIDs of managed objects.
Related concept
Read the scenario before looking for a memorised answer.
✓
OIDs are always numeric and follow a hierarchical tree structure.
Why this is correct
Correct: OIDs are numeric identifiers that follow a tree hierarchy (e.g., 1.3.6.1.2.1).
Related concept
Read the scenario before looking for a memorised answer.
✗
The GetBulk operation is supported in SNMPv1.
Why it's wrong here
Incorrect: GetBulk is not supported in SNMPv1; it was introduced in SNMPv2c.
✗
The sysDescr OID (1.3.6.1.2.1.1.1.0) is a read-write object.
Why it's wrong here
Incorrect: sysDescr is read-only; it contains system description information.
✗
A single MIB object can have multiple OIDs.
Why it's wrong here
Incorrect: Each MIB object has exactly one unique OID.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 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.
