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 interface will actively transmit LACP packets to initiate and negotiate the aggregation with the peer device.
Why this is correct
Active mode means the port initiates LACP negotiations. Passive mode waits for the peer to initiate.
- ✗
The interface will only respond to LACP packets and never transmit them.
Why it's wrong here
That describes LACP passive mode.
- ✗
Active mode can only be used when connecting Juniper switches to non-Juniper servers.
Why it's wrong here
LACP active mode can be used with any standards-compliant LACP peer.
- ✗
LACP active mode requires static pinning of member links and disables dynamic hash selection.
Why it's wrong here
LACP dynamically negotiates member links and does not require static pinning.
