The answer is BGP routing configuration and failover, alongside latency and bandwidth requirements. Latency and bandwidth are critical because SAP applications are highly sensitive to network performance; insufficient bandwidth or high latency can degrade transaction processing and user experience, especially for real-time data replication. BGP routing and failover ensure that if the primary Direct Connect link goes down, traffic automatically reroutes through a backup path, maintaining business continuity for mission-critical SAP workloads. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that Direct Connect planning must prioritize both performance metrics and resilient routing—not VPC subnets, security groups, or endpoints, which are internal VPC constructs. A common trap is confusing Direct Connect factors with general VPC networking. Remember the mnemonic “LBR” for Latency, Bandwidth, and Routing—the three pillars that directly impact SAP migration success over Direct Connect.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 factors are most important to consider when planning the network connectivity for an SAP migration to AWS using AWS Direct Connect?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Latency and bandwidth requirements.
The two most important factors are the latency and bandwidth requirements, and the routing configuration (BGP) for failover. Option A is important for performance; Option B is important for reliability. Option C is wrong because VPC endpoints are not a Direct Connect factor. Option D is wrong because subnets are internal to VPC. Option E is wrong because security groups are not a Direct Connect factor.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Number of VPC endpoints required.
Why it's wrong here
VPC endpoints are for private connectivity to AWS services, not Direct Connect.
✗
Security group rules for the SAP application.
Why it's wrong here
Security groups are network firewalls, not Direct Connect planning.
✓
Latency and bandwidth requirements.
Why this is correct
Direct Connect provides consistent latency and dedicated bandwidth.
Subnet IP range is important but not a Direct Connect specific factor.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related PAS-C01 subnetting questions on CIDR, address ranges, and subnet selection.
