Quick Answer
The correct answers are reject and discard, as both static route options result in traffic being dropped at the router. The reject option drops packets and sends an ICMP unreachable message back to the source, while the discard option drops traffic silently without any notification. On the JNCIA-Junos exam, this concept tests your understanding of how Junos handles unreachable destinations in the routing table, often appearing as a multiple-choice question where you must distinguish between these two drop behaviors and other options like next-table or resolve. A common trap is confusing reject with discard because both drop traffic, but the key difference is the ICMP response. Remember the mnemonic: “Reject replies, Discard is dead silent.”
This JNCIA-JUNOS practice question tests your understanding of routing 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.
Which two static route options result in traffic being dropped at the router? (Choose two.)
install
Why wrong: Install is not a static route option; it is used in other contexts.
reject
Reject drops traffic and sends ICMP unreachable.
next-table
Why wrong: Next-table forwards traffic to another routing table, not drop.
discard
Discard drops traffic silently without ICMP.
resolve
Why wrong: Resolve is used for indirectly connected next-hops.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
reject
The correct answers are B and D. The 'reject' option drops traffic and sends ICMP unreachable. The 'discard' option drops traffic silently. 'Next-table' forwards to another table. 'Resolve' is used for recursive resolution. 'Install' is not a static route option; it's a flag. So B and D are correct.
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.
install
Why it's wrong here
Install is not a static route option; it is used in other contexts.
reject
Why this is correct
Reject drops traffic and sends ICMP unreachable.

Resolve is used for indirectly connected next-hops.
Common exam traps
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
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.
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 JNCIA-JUNOS 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.
