A systems administrator is configuring a storage array. Which of the following should the administrator configure to set up mirroring on this array?
Answer(s): B
To set up mirroring on a storage array, a systems administrator should configure RAID 1. RAID 1, also known as disk mirroring, uses two identical disks to store the same data. If one disk fails, the other disk can be used to recover the data. RAID 0 is not a mirroring RAID level but a striping RAID level that spreads data across multiple disks to enhance performance. RAID 5 and RAID 6 are parity-based RAID levels that provide fault tolerance and can recover data in the event of a single disk failure. However, they are not designed specifically for mirroring.
A systems administrator is working in a globally distributed cloud environment. After a file server VM was moved to another region, all users began reporting slowness when saving files. Which of the following is the FIRST thing the administrator should check while troubleshooting?
Answer(s): A
Network latency is the time it takes for a packet of data to travel from one point to another. When the file server VM was moved to another region, the network latency between the VM and the users increased. This increase in latency is the most likely cause of the slowness when saving files.
A systems administrator adds servers to a round-robin, load-balanced pool, and then starts receiving reports of the website being intermittently unavailable. Which of the following is the MOST likely cause of the issue?
Answer(s): C
When new servers are added to a load balancer pool, there is a possibility they are not fully functioning or properly configured. If the load balancer is routing traffic to these non-operational servers, it would result in the website becoming unavailable.
A company has a cloud infrastructure service, and the cloud architect needs to set up a DR site. Which of the following should be configured in between the cloud environment and the DR site?
Answer(s): D
Replication involves copying data between the primary cloud environment and the DR site to ensure the DR site has up-to-date information in the event of a failover. This is a key part of establishing a functioning DR solution.
A cloud administrator is building a new VM for a network security appliance. The security appliance installer says the CPU clock speed does not meet the requirements. Which of the following will MOST likely solve the issue?
If the CPU on the current host is not fast enough for the appliance, moving it to a host with a faster CPU is the most direct way to resolve the issue
