質問 # 27
You use a bucket in Object Storage to store backups of a database. Versioning is enabled on these objects, so that every time you take a new backup, it creates a new version. You add the following life-cycle policy rule:
{ "action": "DELETE", "is-enabled": true, "name": "Delete-Rule", "object-name-filter": null, "target":
"objects", "time-amount": 60, "time-unit": "DAYS" } Which option is true regarding this rule?
- A. 60 days after the initial creation, any object will be deleted. Deletion will physically de-lete all versions of the object.
- B. Once any specific version is 60 days old, it will be deleted. Deletion will physically delete the data.
- C. If 60 days passes for an object without a new version being created, it will be deleted. Deletion marks the latest version as deleted but does not physically delete it.
- D. 60 days after the initial creation, any object will be deleted. Deletion marks the latest version as deleted but does not physically delete it.

What option should you recommend to add the SSH key to your running instance, while minimizing the administrative overhead? (Choose the best answer.)
- A. You need to configure the boot loader to use ttyS0 as a console terminal on the VM.
- B. You need to reboot the instance from the console, boot into the bash shell in maintenance mode, and add SSH keys for the OPC user.
- C. You need to modify the serial console connection string to include the identity file flag, to specify the SSH key to use.
- D. You need to terminate the running instance and recreate it by providing the SSH key file.

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute Instances that are deployed in a private subnet. The Compute Instances have an attached Network Security Group with a Source Type: Network Security Group (NSG), Source NSG: NSG-
050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:
However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host. What is the root cause of this issue? (Choose the best answer.)
- A. The Security List allows access to all IP address which overrides the Network Security Group ingress rules.
- B. A netmask of /32 allows all IP address in the 140.19.2.0 network, other than your IP 140.19.2.140
- C. All compute instances associated with NSG-050504 are also able to connect to the bastion host.
- D. The port 22 provides unrestricted access to 140.19.2.140 and to other IP address.
正解：C

You have been asked to set up connectivity between a client on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
#Low latency: The applications are financial and require low latency connectivity into OCI.#Consistency: The application is not tolerant of performance variation.
#Performance: The communications link needs to support up to 1.25 Gbps.
#Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN). The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (Choose the best answer.)
- A. Provision FastConnect with a single private virtual circuit.
- B. Provision a site-to-site IPsec VPN between your on-premises network and your virtual cloud network (VCN) using VPN Connect.
- C. Provision FastConnect with a single public virtual circuit.
- D. Provision FastConnect with a single public virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.
- E. Provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.

An insurance company has contracted you to help automate their application business continuity plan. They have the application running in eu-frankfurt-1 as the primary site and uk-london-1 as a disaster recovery site. Normally they have a DNS A record associated with the IP address of the primary endpoint in eu- frankfurt-1. In the event of a disaster, they use OCI DNS Zone Management to update the A record and replace it with the IP address of the end-point in uk- londond-1. How can you automate the failover process? (Choose the best answer.)
- A. Provision a Load Balancer in Frankfurt and associate it with the A record in DNS. Create a backend set with backend servers from both eu-frankfurt-1 and uk- london-1 regions.
- B. Create a Traffic Management Steering policy with Load Balancer type and add both eu-frankfurt-1 and uk-london-1 endpoints. Attach the Traffic Management Steering policy to the A record.
- C. Create a Traffic Management Steering policy and attach it to a backend servers from both eu-frankfurt-1 and uk-london-1 regions.
- D. Create a Health Check that evaluates both regional endpoints. Create a Traffic Management Steering policy with Failover type and associate it with the Health Check.
