You are configuring a SOHO Network and only denying Specific IP Addresses from accessing the Network while allowing any IP Addresses not found on the List. Which of the following should be implemented?
Allow List
Port Forwarding
MAC Filtering
Blocklist
Blocklist
EXPLANATION:
Blocklist is a Form of Protection where only the items identified specifically on the List are Blocked, whereas all others are allowed. For example, if you create an Access Control List that relies on Blocklisting, it would allow every IP address not found in the Allow List.
Allow List is a form of Protection where only the items identified specifically on the List are allowed, whereas all others are denied. For example, if you create a Access Control list that relies on an Allow List, it would block every IP address that is not found in the Allow List.
MAC Filtering is the application of an Access Control List to a Switch or Access Point so that only clients with approved MAC Addresses connect.
Port Forwarding allows a Router to take requests from the Internet for a particular application and send them to a designated host on the LAN.

Due to the increased reliance on the new file server, you have been asked to recommend a RAID solution that will help ensure there is NO unscheduled downtime, NO data loss, and increased speed/performance over the current file server. Based on these requirements, which of the following RAID solutions should you recommend? RAID0 | RAID10 EXPLANATION: RAID 5 provides redundancy, but it will not improve the speed/performance over the current file server in use since it was also a RAID5. Also provides Block-Level striping with distributed parity to provide redundancy using a minimum of 3 disks. RAID0 provides disk striping (Speed/Performance) but no mirroring with a minimum of two disks. RAID1 provides mirroring (Redundancy) but not disk Striping with a minimum of two disks. |
