NEW QUESTION 79
Which statement is true about Oracle Cloud Infrastructure FastConnect?
- A. For public peering, a dynamic routing gateway must be configured and attached to the virtual cloud network (VCN)
- B. For private peering, FastConnect extends your existing infrastructure to a virtual cloud network
- C. For private peering, FastConnect extends your existing infrastructure to allow you to consume object storage from your on-premises data center
- D. The FastConnect provider network offers only 1 Gbps port connection speed increments
Answer: B
Explanation:
With FastConnect, you can choose to use private peering, public peering, or both.
Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). Communication across the connection is with IPv4 private addresses (typically RFC 1918).
Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet.
NEW QUESTION 80
You are implementing Oracle Cloud Infrastructure (OCI) FastConnect to access OCI public accesspoints (e.g.
- object storage). You want other Internet traffic from your on-premises environment to use your existing connection with your ISP.
What is the correct way to establish OCI FastConnect to access these OCI public endpoints?
- A. Configure private peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a default from your network infrastructure to OCI.
- B. Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routingtable and advertise a specific route for your network infrastructure to OCI.
- C. Configure public peering on your FastConnect link with a static route that points to OCI object storage service.
- D. Configure private peering on your FastConnect link with a static route that points toOCI object storage service.

NEW QUESTION 85
Which two statements are true about the Oracle Cloud Infrastructure Object Storage Service? (Choose two.)
- A. It provides strong consistency.
- B. It provides higher IOPS than Block Storage.
- C. Data is stored redundantly across multiple availability domains (ADs) in a multi-AD region.
- D. Data is stored redundantly only in a single AD.
- E. It can be directly attached or detached from a compute instance.
Answer: A,C
Explanation:
STRONG CONSISTENCY When a read request is made, Object Storage always serves the most recent copy of the data that was written to the system. DURABILITY Object Storage is a regional service. Data is stored redundantly across multiple storage servers. Object Storage actively monitors data integrity using checksums and automatically detects and repairs corrupt data. Object Storage actively monitors and ensures data redundancy. If a redundancy loss is detected, Object Storage automatically creates more data copies. For more details about Object Storage durability, see the Oracle Cloud Infrastructure Object Storage FAQ. CUSTOM METADATA You can define your own extensive metadata as key-value pairs for any purpose. For example, you can create descriptive tags for objects, retrieve those tags, and sort through the data. You can assign custom metadata to objects and buckets using the Oracle Cloud Infrastructure CLI or SDK. See Software Development Kits and Command Line Interface for details. ENCRYPTION Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own key. Data encryption keys are encrypted with a master encryption key that is frequently rotated. Encryption is enabled by default and cannot be turned off.
NEW QUESTION 86
You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly-weighted round robin policy to your backend web servers. You notice that one of your web servers is receiving more traffic than other web servers.
How can you resolve this imbalance?
- A. Create separate listeners for each backend web server
- B. Disable session persistence on your backend set
- C. Check security lists and route tables of your virtual cloud network (VCN) and fix any issues associated with the rules
- D. Delete and re-create your OCI load balancer
Answer: B
Explanation:
Session persistence is a method to direct all requests originating from a single logical client to a single backend web server. Backend servers that use caching to improve performance, or to enable log-in sessions or shopping carts, can benefit from session persistence

NEW QUESTION 90
You are a network architect of an application running on Oracle Cloud Infrastructure (OCI). Your security team has informed you about a security patch that needs to be applied immediately to one of the backend web servers. What should you do to ensure that the OCI load balancer does not forward traffic to this backend server during maintenance?
- A. Edit the security list associated with the subnet to avoid traffic connectivity to this backend serve
- B. Create another OCI load balancer for the backend web servers, which are active and handling traffic
- C. Stop the load balancer for maintenance and restart the load balancer after the maintenance is finished
- D. Drain all existing connections to this backend server and mark the backend web server offline
Answer: D
Explanation:
A load balancer improves resource utilization, facilitates scaling, and helps ensure high availability. You can configure multiple load balancing policies and application-specific health checks to ensure that the load balancer directs traffic only to healthy instances. The load balancer can reduce your maintenance window by draining traffic from an unhealthy application server before you remove it from service for maintenance.
The Load Balancing service considers a server marked drain available for existing persisted sessions. New requests that are not part of an existing persisted session are not sent to that server.
Edit Drain State: Opens a dialog box in which you can change the drain state.
If you set the server's drain status to true, the load balancer stops forwarding new TCP connections and new non-sticky HTTP requests to this backend server.
This setting allows an administrator to take the server out of rotation for maintenance purposes.
e. Edit Offline State: Opens a dialog box in which you can change the offline status.
If you set the server's offline status to true, the load balance forwards no ingress traffic to this backend server.
NEW QUESTION 91
You create a public Load Balancer instance and configure a back end set "BES1" with one back end server running a service on port 80.You also create a listener on port 80 and configure that listener to use the back end set "BES1".

How many connections does the Load Balancer maintain?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
NEW QUESTION 92

- A. The instance is taken out of the back end set by the load balancer.
- B. The load balancer stops sending traffic to that instance.
- C. The instance is replaced automatically by the load balancer.
- D. The instance is terminated automatically by the load balancer.
Answer: B
Explanation:
Explanation
