A network administrator was notified that laptop users are unable to access or ping any network resources on the corporate network. Which of the following should the network administrator check FIRST?
Answer: A
Sysadmin/netadmin (also Cisco CCNP, CCSI) w 25 years' field experience here. It's A. The first thing we ALWAYS check (besides "is it plugged in, is it turned on") when troubleshooting network connectivity is "does it have an IP address/did it get a DHCP lease?". The question does not say you're pinging by name, so DNS is NOT the first thing to check. Now, if we can ping by IP and NOT ping by name, then definitely we'd be checking DNS.

Multiple users contact the help desk to report issues with the network fileshares. Files are accessible, but performance is very slow. Which of the following should a technician perform first?
Answer: C
The correct answer is C. Check the RAID drive status LEDs. RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple physical disks into a logical unit that provides improved performance, reliability, or both1. RAID can be implemented using hardware or software, and there are different levels of RAID that use different methods of data distribution and redundancy1. One of the common issues with RAID is disk failure, which means that one or more of the disks in the array stop working properly. Disk failure can affect the performance and availability of the network fileshares, depending on the RAID level and the number of failed disks2.

An engineer is installing a 500W power supply in a server that requires continuous availability. Which of the following is the most suitable type of power supply for the application?
Answer: A
Modular, switched-mode, and semi-modular power supplies are not as suitable for applications that require continuous availability. Modular power supplies allow you to add or remove power supply modules as needed, but they are not as reliable as redundant power supplies. Switched-mode power supplies are the most common type of power supply, but they are not as efficient as redundant power supplies. Semi-modular power supplies are a hybrid of modular and non-modular power supplies, but they are not as reliable as redundant power supplies.

Answer: D
A load balancer is a device or software program that distributes incoming network traffic across multiple servers.

Load balancers can also be used to improve the security of a website or application by redirecting traffic away from servers that are down or under attack.
