Which statement is TRUE about delegating an existing domain to the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Domains can be delegated to OCI DNS via FastConnect partners.
- B. All domains can be retrieved to OCI DNS via DYN.
- C. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
- D. Domains can be delegated to OCI DNS from the OCI Marketplace.
- E. Domains can be self-delegated to OCI DNS from its own service portal.
Answer: C
Explanation:
Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal. The explanation is that delegating a domain to OCI DNS means that you are transferring the authority to resolve DNS queries for your domain from your current DNS provider to OCI DNS. To delegate a domain to OCI DNS, you need to create a zone in OCI DNS that matches your domain name and add any records that you want to serve from OCI DNS. Then, you need to update the name servers for your domain at your Domain Registrar's self-service portal with the name servers provided by OCI DNS. This will point your domain to OCI DNS and allow it to resolve DNS queries for your domain.
NEW QUESTION # 37
You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within14 to 16 days and sends you anotification.
What would happen if you choose not to proactively reboot the instance beforethe scheduled maintenance duedate?
- A. The instance will get terminated.
- B. You will receive another notification to reboot within the next 14 days.
- C. You will receive another notification to reboot within the next 7 days.
- D. The instance is either reboot-migrated or rebuilt in place for you.
Answer: D
Explanation:
Explanation
If you choose not to proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. Reboot-migration is a process where OCI migrates your instance to a new physical host without changing its configuration or public IP address. Rebuild in place is a process where OCI shuts down your instance, performs maintenance on the physical host, and restarts your instance with the same configuration and public IP address. The other options are not correct. References:
[Reboot-Migration], [Rebuild in Place]
NEW QUESTION # 38
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. Now, you would like to create a new volume from the volume replica in the US West (San Jose) region.
What should you do?
- A. Initiate the replica.
- B. Activate the replica.
- C. Trigger the replica.
- D. No action required. By default, the replica is available as a block volume.
Answer: B
Explanation:
The explanation is that when you enable Cross Region Replication for a block volume, Object Storage creates a replica of the volume in another region of your choice. The replica is not available as a block volume until you activate it. To activate a replica, you need to select the replica from the Block Storage console and click Activate Replica. This will create a new block volume from the replica in the destination region.
NEW QUESTION # 39
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- B. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- C. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
- D. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
Answer: A
Explanation:
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.
NEW QUESTION # 40
You want to distribute DNS traffic to different endpoints based on the locationof the end user. Which TrafficManagement Steering Policy would you use?
- A. Load Balancer
- B. Failover
- C. Geolocation
- D. IP Prefix
Answer: C
Explanation:
Explanation
The explanation is that geolocation is a type of Traffic Management Steering Policy that allows you to distribute DNS traffic to different endpoints based on the location of the end user. Geolocation steering policies use geolocation data from third-party providers to map end user IP addresses to geographic regions.
You can create rules that specify which endpoints to serve for each region or country, or use a default endpoint for unspecified regions.
