You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.
Which of the below option is NOT true for such a solution?

A.If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.

B.You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.

C.Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.

D.Block volumes attached as read-only are configured as shareable by default.

Your customer recently ordered for a 1-Gbps Fast Connect connection In ap-tokyo-1 region of Oracle Cloud Infrastructure (OCI). They will us this to one Virtual cloud Network (VCN) in their production (OC1) tenancy and VCN In their development OC1 tenancy As a Solution Architect, how should yon configure and architect the connectivity between on premises and VCNs In OCI?

A.Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways.

B.You cannot achieve connectivity using single FastConnect link as the production and the development VCNs-are in separate tenancies. Request one more FastConnect connection.

C.Create a single private virtual circuit over FastConnect and attach fastConnect to either of the VCN's Dynamic Routing Gateway. Use Remote Peering to peer production and development VCNs.

D.Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on-premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)

What should you do to get this upgrade done without application downtime? (Choose the best answer.)

A.1. Shutdown the worker nodes 2. Create a new node pool 3. Manually schedule the pods on the newly built node pool

B.1. Create a new node pool using the latest available Operating System image. 2. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 3. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 4. Delete the old node pool

C.1. Create a new node pool using the latest available Operating System image 2. Run kubectl taint nodes """"all node""role.kubernetes.io/master"" 3. Delete the old node pool

D.1. Run kubectl cordon <node name> against all the worker nodes in the old pool to stop any new application pods to get scheduled 2. Run kubectl drain <node name> """"delete""local""data """"force """"ignore""daemonsets to evict any Pods that are running 3. Download the patches for the new Operating System image 4. Patch the worker nodes to the latest Operating System image

You have designed and deployed your Autonomous Data Warehouse (ADW) such that it is accessible from your on-premises data center and servers running on both private and public networks in Oracle Cloud Infrastructure (OCI).

As you are testing the connectivity to your ADW database from the different access paths, you notice that the server running on the private network is unable to connect to ADW. Which two steps do you need to take to enable connectivity from the server on the private network to ADW? (Choose two.)

A.Add an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24

B.Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0/: target type of NAT Gateway, add a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0./0 and for all IP protocols.

C.Add an entry in the access table list of ASW for CIDR block 10.2.2.0/24.

D.Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0./0; target type of internet Gateway, add a stateful egress in the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols.

E.Add an entry in the access control list of ADW for IP address 129.146.160.11
