Which two statements about the MQC (Modular QoS CLI) classification process are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A class map can contain multiple match statements that are evaluated using a logical OR when the match-any keyword is configured.
The MQC classification process relies on class maps to define match criteria. A class map with match-any uses logical OR between match statements (A is correct). A class map with match-all requires all match statements to be true (E is correct). Option B is a true statement about MQC, but it describes the policy map evaluation process (which applies actions after classification) rather than the classification process itself. Option C is false because class-default is always present and can be used even when other class maps exist. Option D is false because match statements can reference DSCP values.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A class map can contain multiple match statements that are evaluated using a logical OR when the match-any keyword is configured.
Why this is correct
Correct. When match-any is used, multiple match statements are evaluated with a logical OR; any single match qualifies the packet.
- ✗
In a policy map, class maps are evaluated in the order they are configured, and the first matching class map is applied to the packet.
Why it's wrong here
While this statement is true about MQC policy maps, it describes the application of actions after classification, not the classification process itself. Therefore, it is not one of the two best answers for this question.
- ✗
The class-default class is used only when no other class map is defined in the policy map.
Why it's wrong here
Incorrect. The class-default class is always present implicitly, even if other class maps are defined. It is used for any packet that does not match user-defined classes.
- ✗
Match statements in a class map can reference ACLs, NBAR protocols, or CoS values, but not DSCP values.
Why it's wrong here
Incorrect. Match statements in a class map can reference DSCP values. DSCP is commonly used as a match criterion in MQC class maps.
- ✓
A class map configured with match-all requires that all match statements be true for the packet to belong to that class.
Why this is correct
Correct. A class map configured with match-all requires that every match statement be true for the packet to belong to that class, implementing a logical AND.
