Answer: B
Explanation: https://www.safaribooksonline.com/library/view/foundation-learning- guide/9780132652933/ch08.html
"Layer 2 In-Band Designs The Layer 2 in-band topology is the most common deployment option.
[...]
This is the most scalable design in large L2-to-distribution environments, because this design can be
transparently implemented in the existing network supporting multiple access layer switches. It supports all network infrastructure equipment. The Cisco NAS supports per- user ACLs."

A. The core layer should use default Layer 3 hash information.
B. The core layer should use default Layer 4 hash information.
C. The distribution layer should use default Layer 3 hash information.
D. The distribution layer should use default Layer 4 hash information.
E. The core layer should use Layer 3 and Layer 4 information as input to the Cisco Expressing Forwarding hashing algorithm.
F. The distribution layer should use Layer 3 and Layer 4 information as input into the Cisco Expressing
Forwarding hashing algorithm.
Answer: A,F

Q10. DCI: simple extend layer 2 data center less than 4000 VLAN ? (Choose Two)
A. OTV
B. VXLAN
C. LISP
D. MPLS
E. L2TP
Answer: A,D
Explanation:
MPLS using AToM or VPLS I guess..
VXLAN could do it but I think they would have not specified "<4000 vlans" if they wanted us to answer that.
In fact, we could even think of L2TPv3...
Even if it's really dirty, it's possible (https://www.cisco.com/c/en/us/td/docs/ios/12_0s/feature/guide/l2tpv30s.html#wp1027175 "For L2TPv3, an Ethernet subinterface configured to support VLAN switching may be bound to an Xconnect service so that all Ethernet traffic, tagged with a VID specified on the subinterface, is tunneled to another PE.")
