- From the Service Console click the Administration link.
-Click Download Client Credentials (Wallet).
- On the Download Client Credentials (Wallet) page, enter a wallet password in the Password field and confirm the password in the Confirm Password field. The password must be at least 8 characters long and must include at least 1 letter and either 1 numeric character or 1 special character. This password protects the downloaded Client Credentials wallet.
- Click Download to save the client security credentials zip file. By default the filename is:
Wallet_databasename.zip. You can save this file as any filename you want. You must protect this file to prevent unauthorized database access.
The zip file includes the following:
tnsnames.ora and sqlnet.ora: Network configuration files storing connect descriptors and SQL*Net client side configuration.
cwallet.sso and ewallet.p12: Auto-open SSO wallet and PKCS12 file. PKCS12 file is protected by the wallet password provided in the UI.
keystore.jks and truststore.jks: Java keystore and truststore files. They are protected by the wallet password provided while downloading the wallet.

NEW QUESTION # 103
A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which hasan Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.
Which option would remedy this situation?
- A. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Internet Gateway (IGW) - B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.
- C. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Service Gateway (SGW) - D. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Dynamic Routing Gateway (DRG)
Answer: A
Explanation:
Explanation
You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.
For traffic toflow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic.
For the purposes of access control, you must specify the compartment where you want the internet gateway to reside. If you're not sure which compartment to use, put theinternet gateway in the same compartment as the cloud network.
NEW QUESTION # 104
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like to minimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability.
