- A
Advertise different on-premises prefixes on each connection
Why wrong: All prefixes should be advertised on both connections for full redundancy.
- B
Advertise the same prefixes with different prefix lengths to influence route selection
AWS prefers more specific prefixes (longer prefix length).
- C
Configure a unique private ASN for each Direct Connect connection
Different ASNs prevent BGP loop prevention from rejecting routes.
- D
Set the same MED value for prefixes advertised on both connections
Why wrong: Using the same MED does not help differentiate paths.
- E
Use different BGP community tags for each connection to influence routing policies
BGP communities can be used to set local preference on AWS.

ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company is designing a highly available hybrid network using two AWS Direct Connect connections from different providers. The company wants to use BGP to advertise the same on-premises prefixes to AWS. Which THREE practices should be followed to ensure high availability and optimal traffic flow? (Choose three.)
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
✓
Advertise the same prefixes with different prefix lengths to influence route selection
Option B is correct because advertising the same prefixes with different prefix lengths allows AWS to prefer the more specific prefix, enabling path selection and load balancing while maintaining redundancy. Option C is correct because using a unique private ASN for each Direct Connect connection prevents BGP's AS_PATH loop detection from discarding routes when both connections advertise the same prefixes. Option E is correct because using different BGP community tags for each connection allows you to influence routing policies (e.g., via local preference) to control traffic flow. Option A is incorrect because advertising different prefixes on each connection compromises redundancy; if one connection fails, its prefixes become unreachable. Option D is incorrect because setting the same MED value on both connections provides no differentiation for path selection, whereas using different MED values can influence which connection is preferred.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
