Question

An application developer needs to test an application across all of the operating systems used by the company. Each operating system will be tested individually in a lab environment. The company would like to minimize any additional hardware purchases for this project. Which of the following would be the BEST way to test this application? ❍ A. Purchase a system that is configured just above the hardware requirements for the highest-end operating system. Create separate VMs for each operating system. ❍ B. Purchase individual test computers that match the hardware requirements for each OS. Install different operating systems on each test computer. ❍ C. Designate existing user workstations to be used as testing systems. Run all application tests during non-working hours. ❍ D. Purchase a system that matches the minimum hardware requirements for the highest-end operating system. Create a system image for each operating system and reimage the computer between tests.

Answer 1

The Answer: A. Purchase a system that is configured just above the hardware requirements for the highest-end operating system. Create separate VMs for each operating system. Creating virtual machines for these tests would be a great way to minimize hardware costs, and the machine used for the testing should be able to properly virtualize the testing OS while the host OS is running. Purchasing a system that is slightly more powerful than the highest-level operating system configuration should cover any technical requirements.

Answer 2

The Answer: B. Category 6 The physical characteristics of networking cables are separated into categories. A category 6 cable can support a ten gigabit per second 10GBASE-T network to a distance of thirty-seven to fifty-five meters. The incorrect answers: A. Category 5 Category 5 copper cables can support a one gigabit per second 1000BASE-T network up to one hundred meters. Ten gigabit per second speeds are not support over category 5 cable. C. Category 5e Category 5e (enhanced) is a minor update to category 5, and the Ethernet standards supported for a category 5e cable are identical to those of a category 5 cable. Therefore, category 5e copper cables can support a one gigabit per second 1000BASE-T network up to one hundred meters in length. D. Category 6A Category 6A (augmented) cables can support ten gigabit per second 10GBASE-T connections to a distance of one hundred meters.

Answer 3

The Answer: C. Check the DNS configuration One of the most noticeable of the IP (Internet Protocol) configuration settings was that the DNS (Domain Name Service) server IP address was configured to be the same as the local device. Since DNS servers are commonly separate (and often remote) devices, it would be unusual to see a DNS configured with the same IP address of the local device. The next step should be to confirm the DNS settings with the local network administrator.

Answer 4

The Answer: A. Resource pooling Resource pooling places all of the computing resources in one place, and then distributes from the pool when needed. A VM (Virtual Machine) manager using a portion of available physical memory is taking advantage of resource pooling. The incorrect answers: B. Rapid elasticity Rapid elasticity is the characteristic of scaling up or down cloud resources with demand. More resources will be made available during busy times, and those resources will be seamlessly removed when the demand is low. C. Metered Metered resources are measured based on usage. As more information is uploaded, stored, and downloaded, the costs are tracked and billed accordingly. D. On-demand Cloud computing allows the users to create or remove resources at any time, or on-demand. This flexibility allows organizations to quickly react to changes, deploy updates, and remove excess resources

Answer 5

D. Perform a full backup of the server A clicking noise indicates some type of hardware issue with the computer, so the first step would be to confirm that a recent backup is available for all of the data on this system. If the computer fails completely, at least the data will be secure.

Answer 6

The Answer: A. Check the SMTP settings If you're sending an email message from an email client, you're commonly using SMTP (Simple Mail Transfer Protocol). There are three SMTP configuration settings that are important; the SMTP server name or IP address, the SMTP username, and the SMTP password. The incorrect answers: B. Check the IP address configuration If there were problems with the IP configuration, the manager would not be able to receive any email messages. In this question, the issue does not appear to be related to the IP address configuration. C. Send a test message using web-based email Sending an email message over web-based email would effectively bypass the local email client and would not help troubleshoot the local issues. D. Check the IMAP settings IMAP (Internet Message Access Protocol) is used for receiving email and not for sending email. In this example, the manager was able to receive messages, so the IMAP settings would most likely be working properly

Answer 7

The Answer: A. WPA2 encryption Configuring WPA2 (Wi-Fi Protected Access II) encryption would prevent unauthorized users from accessing the wireless network and would encrypt the data sent over the wireless network. The incorrect answers: B. SSID suppression Preventing the SSID (Service Set Identifier) from appearing in lists of available wireless networks would not provide any significant security feature. If someone knows the name of the network, they would still be able to connect. C. Static IP addressing Static IP (Internet Protocol) addressing is useful for unique environments that require specific IP address assignments, but assigning IP addresses statically doesn't add any significant security to the network. D. UPnP UPnP (Universal Plug and Play) allows network devices to automatically locate and configure other network devices. Generally speaking, the automatic configuration feature of UPnP makes the network LESS secure. E. MAC filtering Filtering traffic by MAC (Media Access Control) address can be easily circumvented with a packet capture application, so MAC filtering would not be considered a security feature.

Answer 8

The Answer: D. Use ad hoc mode Ad hoc mode allows two devices to directly communicate over an 802.11 wireless link without using an access point. The incorrect answers: A. Enable Bluetooth discovery on the tablet Enabling Bluetooth discovery would allow the tablet to use Bluetooth peripherals, but it would not enable 802.11 networking between the tablet and the laptop. B. Configure infrastructure mode on both devices Infrastructure mode is the 802.11 configuration used with an access point. In this question, the two devices need to communicate without using an access point. C. Create shared folders on the laptop computer Creating shared folders would potentially allow access from another device, but the network would need to be available to provide the connectivity.

Answer 9

The Answer: A. Unmanaged switch Switches determine how traffic is forwarded based on the destination MAC (Media Access Control) address in the frame. The qualification of managed or unmanaged is not important in this case, since both types of switches make forwarding decisions the same way. The difference between a managed and unmanaged switch are based on other features not associated with the forwarding process. The incorrect answers: B. Repeater A repeater receives a signal, regenerates the signal, and then passes the signal on to the next network link. There are no forwarding decisions occurring inside of a repeater. C. Router A router makes forwarding decisions based on the destination IP (Internet Protocol) address of a packet. D. Firewall A firewall controls the flow of traffic based on a set of predefined security policies. If the traffic flow matches one of the policies, the firewall can be configured to allow or block that traffic flow.

Answer 10

The Answer: B. Enable Secure Boot Secure Boot is part of the UEFI (Unified Extensible Firmware Interface) standard for a computer BIOS (Basic Input Output System). Secure Boot ensures that the underlying operating system has not been modified by malware or any other process. The incorrect answers: A. Modify the boot drive sequence Changing the boot drive sequence in the BIOS would not resolve the UEFI or Security Boot process. C. Remove the BIOS password UEFI mode and Secure Boot do not require a boot or management password, and removing any of those passwords will not resolve the error message. D. Boot the system with the Windows setup media Booting with separate media would not resolve this issue when booting to the primary storage drive. UEFI mode with Secure Boot is required for this system.
