COMPTIA SERVER + SK0-004 CHAP 3 Which server role uses HTTP as its transfer mechanism? A. Web B. Application C. Directory D. Database - AnswerA. Web servers are used to provide access to information to users connecting to the server using a web browser, which is the client part of the application. It uses the HTTP protocol as its transfer mechanism. Which resource is stressed the most on an application server? A. Disk B. NIC C. CPU D. Memory - AnswerC. The CPU is the component that is stressed on an application server since it is doing all of the processing on behalf of the clients. Multicore and multiple processors are advisable. Which of the following server roles is used to authenticate users to the network? A. Web B. Application C. Directory D. Database - AnswerC. A directory server is one that accepts and verifies the credentials of users. Typically it not only authenticates them but also provides them with access to resources using single sign-on. Which server role automates the process of providing an IP configuration to devices in the network? A. DNS B. Routing and Remote Access C. DHCP D. NTP - AnswerC. DHCP servers are used to automate the process of providing an IP configuration to devices in the network. These servers respond to broadcast-based requests for a configuration by offering an IP address, subnet mask, and default gateway to the DHCP client. Which server role automates the process of providing an IP configuration to devices in the network? A. DNS B. Routing and Remote Access C. DHCP D. NTP - AnswerD. Network Time Protocol (NTP) servers are used as a time source by the devices in the network. This service ensures that log entries that are time stamped can be properly interpreted and that digital certificates, which depend heavily on time, continue to function correctly. Which server role resolves hostnames to IP addresses? A. DNS B. Routing and Remote Access C. DHCP D. NTP - AnswerA. DNS servers resolve device and domain names (website names) to IP addresses, and vice versa. Which of the following are the software stubs that allow devices to communicate with the operating system? A. Drivers B. Patches C. Shims D. Manifests - AnswerA. Device drivers are the software stubs that allow devices to communicate with the operating system. Drivers are used for interacting with printers, monitors, network cards, sound cards, and just about every type of hardware attached to the server. Which of the following describes the average length of time it takes a vendor to repair a device or component? A. MTBF B. MMTR D. Cold site - AnswerA. In load balancing, a frontend device or service receives work requests and allocates the requests to a number of backend servers. This type of fault tolerance is recommended for applications that do not have a long-running in-memory state or frequently updated data. Which of the following means that the device is no longer supported by the vendor? A. Proprietary B. Legacy C. End of life D. Expiration - AnswerC. End of life can mean a couple of different things. From the vendor perspective, it probably means that they no longer provide support for a product. What drives the amount of memory for a print server? A. Number of printers B. Number of users assigned to the printer C. Size of the network D. Fault tolerance required - AnswerB. Print servers need lots of memory to hold the print jobs waiting in the print queue. The exact amount will depend on the number of users assigned to the printers being managed by this print server. Which of the following protocols is used when mail servers send email? A. POP3 B. SMTP C. SNMP D. IMAP4 - AnswerB. Mail servers run email server software and use SMTP to send and receive email on behalf of users who possess mailboxes on the server. Which RAID type increases fault tolerance and performance? A. RAID 0 B. RAID 1 C. RAID 3 D. RAID 5 - AnswerD. RAID 5 can recover from a single disk failure, and it can read multiple drives, thus increasing performance.
