Free Amazon ANS-C01 Actual Exam Questions - Question 12 Discussion
connect from the Direct Connect location provider to the port on your router in the same facility. To
enable the use of your first virtual interface, your router must be configured appropriately.
What are the minimum requirements for your router?
A seems more accurate since single mode fiber is usually for longer distances, and here it’s within the same facility, so multimode fits better. Also, IPsec stuff in C or D isn’t needed for Direct Connect.
It’s A because multi mode fiber is common for short-distance connections inside the same building.
It’s A since multi mode fiber fits shorter distances inside the same facility better.
A/B? Both mention the key elements like 802.1Q VLAN and BGP with MD5, which are definitely needed for Direct Connect. The fiber type is the tricky part—single mode is usually for longer distances, but within the same facility, multi mode could also be right. The question says “in the same facility,” so maybe multi mode fiber from A fits better here? IPsec and GRE tunnels in C and D don’t match the typical Direct Connect setup, so those can be ruled out.
It’s B for me because AWS Direct Connect typically uses single mode fiber for 1-Gbps links, not multi mode. The VLAN tagging with 802.1Q and the BGP session with MD5 authentication are standard requirements, so that checks out. Options C and D mention IPsec and GRE tunnels which aren’t needed for a standard Direct Connect setup, so those can be ruled out. Between A and B, single mode fiber is the more likely choice given the speed and distance typically involved in these connections.
Looks like the fiber type might not be the main point here since both A and B include 802.1Q VLAN, Peer IP, and BGP with MD5, which are all needed. The key difference is single mode vs multi mode fiber. Usually, AWS Direct Connect setups use single mode fiber for these distances and speeds, so I’m going with B on that basis. The rest of the options mention IPsec or GRE tunnels, which aren’t required for a basic Direct Connect virtual interface. So B fits the typical minimum requirements best.
B tbh, the question doesn’t specify whether the fiber should be single mode or multi mode, which makes it tricky to pick between A and B. Also, there's no mention of IPsec or GRE tunnels in the setup, so C and D feel off. Would be great to know if the environment or physical cabling constraints lean toward single mode or multi mode fiber here. Without that detail, it’s hard to be sure which fiber interface type fits best. Anyone else think the lack of fiber type detail makes this ambiguous?
