D.
Power distribution units (PDUs)
E.
Cisco Ethernet switch
Correct answer is; A, D, and E have external ethernet connections.
A is right. app needs to connect to DB
B is wrong. Exadata storage servers do not need external network connectivity
C is wrong. there is no infiniBank storage servers
D is right. PDU A and PDU B are to connect to external for full monitoring. this is needed only if electric currency monitored remotely.
E is right. Ethernet switch needs to be connected to external network
So A.D.E. are correct.
ABC is absolutely wrong answer, Storage and IB are never required to be connected to infrastructure network.
The answer is ADE.
Option C stated as “InfiniBand switches” in the exam.
