Network: Exam Questions

Questions 

1. You have two lines of business operations (LOB1, LOB2) leveraging Oracle Cloud Infrastructure. LOB1 is deployed in VCN1 in OCI east, while LOB2 is deployed in VCN2 in the US West region. You need to peer VC1 and VC2 for disaster recovery and data backup purposes. Which CIDR ranges can be used?

1. VCN1(172.16.1.0/24) and VCN2(172.16.1.0/27)

2. VCN1(192.168.0.0/16) and VCN2 (192.168.1.0/27)

3. VCN1(10.0.0.0/16) and VCN2(172.16.0.0/16)

4. VCN1(10.0.0.0/16) and VCN2(10.0.1.0/24)

2. You deployed a web server in Oracle Cloud Infrastructure using an Ephemeral Public IP address. While making configuration changes, an admin inadvertently deleted your web server. You redeploy your web server, but many of your LOB apps depend on this webserver public IP address and would need an update. What can you do to prevent this from happening again?

1. Create a reserved public IP address and associate it with the virtual NIC of your compute instance

2. Create a reserved public IP address and associate it with the security list of the subnet.

3. Create a reserved public IP address and associate it with the subnet of your compute instance.

4. Create a reserved public IP address and associate it with the "hosts" file in your webserver.
