You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical data. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public internet. The recommended disaster recovery plan is
<u>A. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DRsites.</u>
<u></u>
Explanation:
- Local VCN peering is the process of connecting two VCNs in the same region and tenancy so that their resources can communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.
- You have a central VCN that has resources that you want to share with other VCNs.
- A VCN is a customizable private network in Oracle Cloud Infrastructure. Just like a traditional data center network, a VCN provides you with complete control over your network environment.
- A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments.
- A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice.
Answer:
The definition for the problem is listed in the section below on the explanations.
Explanation:
<u>For SQL Server</u>
- Data Recovery: Data recovery is done well on SQL Server. It is achieved by the restoration method. Behind this, a sysadmin must reconstruct a collection of SQL backups throughout a restore series that is technically right as well as relevant.
- Data Security: There are several approvals as well as limits for accessing main data objects or databases. These data are accessed only by the approved clients.
- Concurrency Control: This is essentially synchronization of the evidence or information accessed by multiple users as well as from separate locations.
Concurrency or Competitiveness control becomes accomplished with SQL Server Portable, using locking to further improve security. The locking regulates how multiple individuals can simultaneously navigate & alter shared storage, without interfering with one another.
Answer:
#include <iostream>
using namespace std;
void swap(int& m, int& n) /* passing by reference so that changes will be made in the original values.*/
{
int t=m;
m=n;
n=t;
}
int main()
{
int val1,val2;
cout<<"Enter the values"<<endl;
cin>>val1>>val2;
cout<<"Values before swap "<<val1<<" "<<val2<<endl;
swap(val1,val2);
//calling the function swap..
cout<<"Values after swap "<<val1<<" "<<val2<<endl;
return 0;
}
Explanation:
Created a function swap with 2 arguments m and n passed by reference.
Answer:
By the numbers: “The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1,800 square feet (167 square meters) of floor space, weighed 30 tons, consumed 160 kilowatts of electrical power.” More info
