Q: 1
You plan to perform migrations between on-premises and OCI. What is the minimum bandwidth required with FastConnect as the dedicated network link between the environments?
Options
19 comments in the community discussion
6
D . Official Oracle guide and hands-on labs both point to 1 Gbps as the starting minimum for FastConnect.
2
Its D, not C. The question asks for minimum, and FastConnect's entry point is 1 Gbps. Option C is just the max capacity in some data centers, easy to mix up.
Q: 2
Which two can help you perform logical online migration to Oracle Autonomous Database?
Options

Actually it's A and D. Golden Gate supports online replication, and SQL Developer can help move schemas/data. Check the docs if you want details.
1
A and D imo, since Golden Gate does online logical replication (real-time, CDC style) and SQL Developer lets you logically move schemas/tables. C is tempting but OCI Database Migration isn't always a true "online logical" method-usually more lift-and-shift or physical options. Pretty sure that's the Oracle line, open t
Q: 3
Which three transfer mediums does the OCI Database Migration service use to perform the initial load of the databases?
Options

B/C/E here. All the initial load methods in OCI DB Migration use Data Pump, while D is for ongoing sync. Not 100 percent but that's what I recall from Oracle docs. Anyone disagree?
1
B C, E seems right here. Data Guard (D) is mainly for ongoing replication, not initial loads with OCI Database Migration. I think the question specifically asks about first transfer, so Data Pump options fit. If someone has seen otherwise in real scenarios let me know.
Q: 4
What capability does Oracle Cloud Infrastructure (OCI) Storage Gateway provide for connecting on- premises applications with OCI Object Storage?
Options
18 comments in the community discussion
2
D imo, since Storage Gateway sits in the middle and lets legacy apps use NFS to talk to object storage. No re-coding for REST needed, that's the point. Unless I'm missing something subtle in the question wording.
1
Looks like it’s D since Storage Gateway translates NFS to Object Storage, so the apps don’t need changes for REST support. That’s how OCI bridges legacy systems. Let me know if I missed some trick here.
Q: 5
Which option best describes the term Inventory Asset in the context of Oracle Cloud Migrations (OCM) service?
Options
16 comments in the community discussion
1
I don't think C is right. A, since "Inventory Asset" is about selected VMs not just discovered ones.
1
Probably A since OCM only treats VMs you pick for migration as Inventory Assets, not just anything it finds automatically. If they haven't been selected, they're not counted that way. Pretty sure that's what exam guides say.
Q: 6
Which resource type would you create in Full Stack Disaster Recovery (FSDR) to represent a consistency grouping of Oracle Cloud Infrastructure (OCI) resources for disaster recovery purposes?
Options
14 comments in the community discussion
6
B. Protection Group is the grouping resource in FSDR for OCI consistency, not Plan or Policy.
1
B , D looks tempting but it's not the grouping resource in FSDR. Seen similar question in practice.
Q: 7
What key benefit does Full Stack Disaster Recovery (FSDR) offer in Oracle Cloud Infrastructure (OCI)?
Options
20 comments in the community discussion
1
I don't think B is right here, D makes more sense. FSDR in OCI is mainly about moving workloads between regions with minimal downtime, which lines up with seamless migration. Accelerated deployment (B) is more of a general cloud benefit, not specific to disaster recovery tools. Pretty sure D fits better but open to oth
1
Why not B? I think people might confuse faster deployment with DR but Full Stack Disaster Recovery is mostly about failover and moving workloads smoothly between regions. Backup management and config deployment are handled elsewhere in OCI. Seems like this is a typical trap where "simplified management" sounds good but
Q: 8
What is the primary function of the Data Transfer Utility provided by Oracle Cloud Infrastructure (OCI)?
Options
19 comments in the community discussion
5
Option D is right, since the utility's job is prepping disks for shipment to Oracle. B is tempting but that's handled by different OCI features, not the Data Transfer Utility. If anyone has a different source, let me know, but pretty sure it's D.
4
D . The Data Transfer Utility's whole point is creating and prepping disks for Oracle to physically move, so not about network transfer between regions or compartments. Ran into this on a practice test, always referring to offline shipment. Open to other thoughts if someone saw a different use case.
Q: 9
What is the primary purpose of Bring Your Own IP (BYOIP) in Oracle Cloud Infrastructure (OCI)?
Options
14 comments in the community discussion
1
C is right here, it's about using your own IPs from an external block in OCI. I've seen similar questions on practice tests, never seen D linked with BYOIP. Happy to hear if anyone has a different take though.
1
Option C is it. The key with BYOIP is letting you use your own IP ranges (ones you already own) inside OCI, not just Oracle's pool. Sometimes people mix this up with leasing from Oracle (A), but that's a different process. Let me know if you see it another way.
Q: 10
How does containerization differ from virtualization in terms of resource optimization?
Options
10 comments in the community discussion
Option C for me, since containers still need an OS to run on, just not a full one inside each container. Maybe I’m missing something but I think VMs share the host hardware differently. Someone correct me if that’s off.
D , since containers share the host OS kernel, they use hardware more efficiently than VMs which each need their own OS. Saw something similar on a practice test. Could be missing something but pretty sure about this.
Q: 11
Which statement describes the transferring phase in the Delta Cycle of Oracle Cloud Infrastructure (OCI) File System replication?
Options
15 comments in the community discussion
1
D imo. Saw a similar question on a practice and it was D.
1
It’s D here. The transferring phase isn’t just about moving data, it grabs the changed snapshot and also commits it to the target system. Pretty sure Oracle docs use that phrasing too, but open if anyone sees it differently.
Q: 12
Which Hybrid Cloud Extension (HCX) migration type is designed for large-scale migration of workloads that cannot afford downtime?
Options
16 comments in the community discussion
1
Not D, it's C. Bulk Migration is fast but still needs downtime, so if zero downtime is required, only C fits that.
Probably C, that's the downtime-safe option for mass migrations.
Q: 13
Which is NOT a valid connectivity model in Oracle Cloud Infrastructure (OCI) FastConnect?
Options
12 comments in the community discussion
2
C/D? Had something like this in a mock and pretty sure D is not a real OCI FastConnect model. The valid options are provider, partner, or colocation, not direct-to-cloud. Agree?
1
C/D? Still not 100 percent since "Colocation with Oracle" sometimes appears in different forms, but pretty sure D is wrong.
Q: 14
How does the Copy to another region feature in Oracle Cloud Infrastructure (OCI) aid in achieving smooth transitions during Block Volume migration?
Options
12 comments in the community discussion
6
Option D is correct. B is tempting but it’s about block volume backups, not whole apps or automation.
1
Its D here since OCI just replicates Block Volume backups to the chosen region. It doesn’t handle application logic or real-time sync, so B and C aren’t a fit. Backup copies make migration smoother but it’s not automated app migration. Pretty sure about this but open if anyone disagrees.
Q: 15
In Oracle Cloud Infrastructure (OCI), how are Security Lists different from Network Security Groups (NSGs) in terms of their functionality and application?
Options
14 comments in the community discussion
2
Option C, but if you assign a VNIC to multiple NSGs, you get even more granular control than with Security Lists alone.
1
I've seen similar in recent exam reports, pretty sure it's C
