What is the potential problem in this scenario?

A. The Load Balancer health check status Indicates critical situation for half of the backend webservers
B. The Database Is down hence users can not access the web site
C. The Traffic Management Policy is not set to load Balancer the traffic to the web servers.
D. All the web servers are too busy and not able to answer any request from users.
E. You did not configure a Service Gateway to allow connection between web servers and load Balance

問題 #3

For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.
Which option should you recommend to provide the highest level of redundancy?

A. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location
B. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective
C. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure
D. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.
