OCI Certification Sample Questions with Verified Solutions

OCI Certification Sample Questions with Verified Solutions What resources are solely in a AD? 1. Block/Boot volume 2. Compute Instance You have an instance that is running slow because its storage needs more space. What would you recommend to increase the storage? You would terminate and preserving the boot volume and create another instance from that boot volume with a Dense IO storage Back up the instance to object storage. Terminate it and create another dense IO instance from your back up If there multiple boot/block volumes on multiple instances what is the best way to back them up? Volume group Ephemeral IP address? Temporary and existing for the lifetime of the instance Can only be assigned to primary private IP Only one per VNIC Which DB can do automatic CPU and storage scaling 1. ATP 2. ADW When you stop an instance do you continue to get charged? You don't get charged for the service if it's stopped but you still get charged for the storage Best place to store images? (Where are the image resources) 1. Boot volume 2. Custom image You can have a custom image and are trying to create an instance from it. What is the best way to import that custom image Object storage path url Download to your desktop and then use it that way Operations department has a custom image in its compartment. Finance compartment needs access to this image. How do you get access to the operations compartment? Use a Pre-Authenticated Request for the custom image and use that as the custom image source Have services set up on-prem and need to transfer all the service to OCI at least 500 miles apart. What is the recommended way of doing that? (Their region is in Phoenix) Set up VCNs in separate regions and use a remote peering connection Have services set up on-prem and need to transfer all the service to OCI 300 miles apart. How would you do it the most efficient way? What is the recommended way of doing that? Set up VCN in a single region Load balancing policies to distribute traffic; Load balancing algorithms 1. Round Robin 2. Least Connection 3. IP Hash Internet Intelligence? Provides insight into the performance of cloud region vantage points to markets and providers around the globe, for both long-term strategy and operational troubleshooting. Federation SSO ID Options 1. Oracle IDCS 2. Microsoft Active Directory CIDR range? /16 to /30 Limits about maximums for multipart uploading 10TB maximum 10 MB to 50 GB for API upload Which statements are true about encryption? DBCS offers an encrypted DB By default, Object Storage and Block Storage are encrypted at rest What happens to a compute instance that fails to pass health checks? LB stops sending traffic to that instance An instance is launched with a primary VNIC that is created during instance launch. Which two operations are true when you add secondary VNICs to an existing instance? 1. You can remove the secondary VNIC later if not needed 2. The primary and secondary VNICs must be in the same AD How many security lists per subnet? 5 Differences between FSS and Block storage protocols FSS : NFSv3 Block : iSCSI 2 DRGs in a VCN using Remote Peering Connection (RPC) are not able to talk to each other. Troubleshoot. 1. Route table is not updated with DRG 2. Security lists are not correct OCI tenancy is in Frankfurt, but clients are complaining for performance. Tool to use? Internet Intelligence Server is using an ephemeral IP which is gone when restarted. How to prevent this? Put the reserved public IP address in VNIC?? Assign reserved public IP in the subnet?? App is in dev stage; choose a database with least cost to find the status of fault tolerance ADW On-prem to OCI database migration RMAN and Object Storage What is true about databases naming conventions Cannot concurrently use the same name for ATP and ADW How to deny access in file storage at the file level? 1. Unix user rights 2. Export options - client access read only?? Company with 5 different office locations and 1 VCN. Need a secure and encrypted connection IPSec VPN - 5 connections with 1 DRG Which 2 are true about Object Storage? 1. AD Scope 2. Regional scope 3. Encrypted at rest 4. Encrypted in transit 1. Regional scope 2. Encrypted at rest Standard compute instance is not performing well. What to do to increase performance? Preserve the boot volume and run spin up a Dense IO shape Where can you import or export custom images? Object storage How to extend connections from on-prem to OCI FastConnect Private subnet has a database and need access from database Use service gateway Can you have only one secondary VNIC? No, you can have multiple There are 3 ADs. How many subnets are required for load balancing 2 web servers, and 2 db/backend servers? 5 AD1: Sub 1 - Webserver 1; Sub 2 - Webserver 2 AD2: Sub 1 - Webserver 1; Sub 2 - Webserver 2 AD3: Sub 1 - Load Balancer How do you access a File System? IAM policies Which two statements are true about DBCS? 1. You have full control over backup schedule and retention 2. You can manage Oracle parameters at a global system level You are responsible for setting up access for all cloud users of a large enterprise. You log in to the PHX region and start creating users and policies. You the . realize that some users might be creating resources in the IAD region. Which step should you perform to enable those users? IAM users are global. As an admin, make sure that you subscribe to the IAD region. How can you preserve the boot volume while terminating the instance? Disable the option to delete it and then terminate the instance. ATP/ ADW consumer SQL statements: If Medium = 0: High = ? High = 3 SQL Statements ATP/ ADW consumer SQL statements: If Medium = 20: High = ? High = 0 SQL Statements
