Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q39-Q44):

NEW QUESTION # 39
Which TWO options will accomplish a fully redundant connection from an on-premises data center to a Virtual Cloud Network (VCN) in the us-ashburn-1 region?

A. Configure one FastConnect virtual circuit to the us-ashburn-1 region and the second FastConnect virtual circuit to the us-phoenix-1 region.
B. Configure a Site-to-Site VPN from a single on-premises CPE.
C. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
D. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region.

Answer: C,D

Explanation:
For a fully redundant connection from an on-premises data center to a VCN in the OCI us-ashburn-1 region, it is important to ensure high availability and fault tolerance. Here's how each option contributes to redundancy:
Option B: Two FastConnect Virtual Circuits:
FastConnect provides a dedicated, private connection with higher bandwidth and more consistent performance compared to a VPN. To achieve redundancy, you can configure two FastConnect circuits in the same region (us-ashburn-1), each terminated on diverse hardware on-premises. This setup ensures that even if one circuit or its associated hardware fails, the other circuit can maintain the connection. This ensures no single point of failure in the connectivity to OCI. Thus, option B is correct.
Option D: FastConnect and Site-to-Site VPN:
Another approach to redundancy is to have a mix of connection types. By setting up one FastConnect circuit and one Site-to-Site VPN, both terminating in the same region (us-ashburn-1), you create a diverse connection path. If the FastConnect connection fails, traffic can automatically route through the VPN connection, maintaining connectivity. This setup adds an extra layer of redundancy, making option D correct as well.
Incorrect Options:
Option A: Only configuring a Site-to-Site VPN from a single on-premises CPE does not provide redundancy because it involves just one connection path. If that connection or the CPE fails, there would be no fallback.
Option C: Configuring FastConnect circuits to different regions (us-ashburn-1 and us-phoenix-1) does not provide redundancy within a single region but rather across regions, which is not required for regional redundancy.
Relevant OCI Documentation:

Using Site-to-Site VPN and FastConnect for Redundancy
These references offer more detailed information on setting up redundant connections and the benefits of each connection type within OCI.

NEW QUESTION # 40
What happens to the performance level of a volume when it is detached from an instance?

A. The performance level is adjusted to Higher Performance.
B. The performance level is adjusted to Balanced.
C. The performance level is adjusted to Lower Cost (0 VPUs/GB).
D. The performance level remains unchanged.

Answer: C

Explanation:
In Oracle Cloud Infrastructure (OCI), when a block volume is detached from an instance, its performance level is automatically adjusted to the "Lower Cost" tier, which provides 0 VPUs (Volume Performance Units) per GB. This adjustment helps reduce costs when the block volume is not actively being used by a compute instance.
Key Points:
Volume Performance Levels: OCI offers various performance tiers for block volumes, including "Higher Performance," "Balanced," and "Lower Cost." These tiers determine the level of IOPS (Input/Output Operations Per Second) and throughput available to the volume.
Automatic Adjustment: When a block volume is detached from an instance, OCI automatically optimizes the cost by switching the volume to the "Lower Cost" performance tier. This tier offers minimal performance, suitable for data that is not actively accessed.
Cost Management: This automatic adjustment is beneficial for managing costs, as it prevents users from incurring unnecessary charges for higher performance levels when the volume is not in use.

NEW QUESTION # 41
Which statement is TRUE about delegating an existing domain to the Oracle Cloud Infrastructure (OCI) DNS service?

A. Domains can be self-delegated to OCI DNS from its own service portal.
B. Domains can be delegated to OCI DNS via FastConnect partners.
C. All domains can be retrieved to OCI DNS via DYN.
D. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.

Answer: D

Explanation:
To delegate a domain to the Oracle Cloud Infrastructure (OCI) DNS service, the domain needs to be pointed to OCI's DNS servers. This can be done through the Domain Registrar's self-service portal, where you update the name servers for your domain to OCI's DNS servers.
Process: You typically log into the domain registrar where your domain is registered and replace the existing name servers with the name servers provided by OCI DNS. Once this is done, DNS queries for your domain will be directed to OCI DNS.

NEW QUESTION # 42
Which authentication option should you use to ensure third-party APIs communicate with OCI resources?

A. API Signing Key
B. OCI Username and Password
C. Auth Tokens
D. SSH Key Pair with 2048-bit algorithm

Answer: A

Explanation:
When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option is API Signing Key.
API Signing Key: This method uses an RSA key pair to authenticate and sign API requests. The API signing key provides a secure and reliable way to ensure that the API requests to OCI are coming from an authorized source. It is commonly used for programmatic access to OCI services.
Other Options:
SSH Key Pair: Primarily used for secure shell access to compute instances, not for API authentication.
Auth Tokens: Typically used for authentication in environments where APIs don't support the API Signing Key, such as OCI CLI or SDKs.
OCI Username and Password: Generally used for the Console login, not for securing API communications.
Relevant OCI Documentation:
API Signing Key Authentication
This documentation provides details on using API Signing Keys for secure API communication in OCI.

NEW QUESTION # 43
Which of the following is a valid RFC 1918 CIDR prefix that can be used for creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN)?

A. 192.268.0.0/24
B. 192.168.0.0/16
C. 0.0.0.0/0
D. 10.0.0.0/8

Answer: B,D

Explanation:
RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:
192.168.0.0/16: A private IP range often used in home networks.
10.0.0.0/8: A large private IP range commonly used in enterprise networks.
Invalid Options:
B . 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.
C . 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.
