Question 2:
You are designing a high bandwidth, redundant connection between your data center and Oracle Cloud Infrastructure (OCI). While researching for OCI FastConnect locations, you notice that you are co-located with Oracle at one of the Oracle
FastConnect locations in the Ashburn region.
What is the recommended design in this scenario?
A. Create a cross-connect group and have two or more cross-connects in that group. Create an IPsec VPN connection on this group. B. Setup two IPsec connections between your data center and OCI Ashburn region. Create a OCI load balancer to distribute the traffic across the two connections. C. Create a cross-connect group and have at least two or more cross-connects in that group. Create at least two or more virtual circuits in the group. D. Create a cross-connect group and have at least one cross-connect in that group. Create at least one virtual circuit in the group.
C. Create a cross-connect group and have at least two or more cross-connects in that group. Create at least two or more virtual circuits in the group.
You could have multiple private virtual circuits, for example, to isolate traffic from different parts of your organization (one virtual circuit for 10.0.1.0/24; another for 172.16.0.0/16), or to provide redundancy.
Question 3:
What is true about data guard set up with fast-start failover (FSFO) in Oracle Cloud Infrastructure (OCI)?
A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs). B. When you configure data guard using OCI console, the default mode is set to maxprotection. C. You cannot create the standby DB system in a different AD from the primary DB system. D. You cannot use database command line interface (CLI) to set up data guard with FSFO.
A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs).
References: The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains. The observer determines whether or not to failover to a specific target standby database https://docs.cloud.oracle.com/enus/iaas/Content/Database/Tasks/usingDG.htm#ConfiguringObserverOptional
Question 4:
Which two statements are true about an Oracle Cloud Infrastructure (OCI) virtual cloud network (VCN)? (Choose two.)
A. To delete a VCN, its subnets must contain no resources. B. A VCN can have multiple CIDR blocks associated with it. C. In regions with multiple Availability Domains (AD), each AD should have their own VCN assigned to it. D. If you own a block of public IPs, you can assign it to one of your VCNs. E. A VCN covers a single, contiguous IPv4 CIDR block of your choice.
A. To delete a VCN, its subnets must contain no resources. E. A VCN covers a single, contiguous IPv4 CIDR block of your choice.
Which option is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?
A. Clone an existing volume to a new, larger volume. B. Restore from a volume backup to a larger volume. C. Shrink an existing volume in place with offline resizing. D. Expand an existing volume in place with offline resizing.
C. Shrink an existing volume in place with offline resizing.
Question 7:
As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC) cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:
The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.
The cluster must be resilient to any potential infrastructure failures. To minimize latency, all nodes must be deployed within the same availability domain (AD). Adding or replacing nodes within the cluster should take no more than 30 minutes.
Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)
A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system. B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD. C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time. D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time. E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD. D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains. To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain. Use fault domains to do the following things: Protect against unexpected hardware failures or power supply failures. Protect against planned outages because of Compute hardware maintenance.
Question 8:
You are an administrator with an application running on OCI. The company has a fleet of OCI compute virtual instances behind an OCI Load Balancer. The OCI Load Balancer Backend Set health check API is providing a `Critical' level
warning. You have confirmed that your application is running healthy on the backend servers.
What is the possible reason for this `Critical' warning?
A. A user does not have correct IAM credentials on the Backend Servers. B. The Backend Server VCN's Route Table does not include the route for OCI LB. C. OCI Load Balancer Listener is not configured correctly. D. The Backend Server VCN's Security List does not include the IP range for the source of the health check requests.
D. The Backend Server VCN's Security List does not include the IP range for the source of the health check requests.
References: "In this case, your security rules might not include the IP range for the source of the health check requests. You can find the health check source IP on the Details page for each backend server. You can also use the API to find the IP in the sourceIpAddress field of the HealthCheckResult object." https://docs.cloud.oracle.com/iaas/Content/Balance/Tasks/editinghealthcheck.htm#health-status
Question 9:
You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). You want to provide access to this cluster to other team members. What should you do to provide access to this cluster using as fewest steps as possible?
A. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell. B. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell. C.
