This configuration will allow users in their domain to access resources in your domain and vice versa. As a security administrator, which tasks should you complete during this phase? (Select two.)

There is latency on the WAN link.

Your organization recently opened a branch office in a remote area. Because of its location, traditional WAN connectivity was not available, so you contracted with a satellite provider to connect the branch office network to your home office network. Recently, your CEO conducted a video conference with the employees at the branch office. The employees complained that the video was choppy and the audio was frequently out of sync with the video. What is the most likely cause of this poor WAN performance?

The WAN provider is throttling bandwidth on the link.

Your organization recently opened a branch office. You contracted with a WAN service provider to connect the branch office network to your home office network. Recently, your CEO conducted a video conference with the employees at the branch office. The employees complained that the video was choppy and the audio was frequently out of sync with the video. What is the most likely cause of this poor WAN performance?

Configure and apply security policy settings in a mobile device management system. Enroll the devices in a mobile device management system.

Your organization recently purchased 18 iPad tablets for use by the organization's management team. These devices have iOS pre-installed on them. To increase the security of these devices, you want to apply a default set of security-related configuration settings. What is the best approach to take to accomplish this? (Select two. Each option is a part of a complete solution.)

Configure and apply security policy settings in a mobile device management system. Enroll the devices in a mobile device management system.

Your organization recently purchased 30 tablet devices for your traveling sales force. These devices have Windows RT preinstalled on them. To increase the security of these devices, you want to apply a default set of security-related configuration settings. What is the best approach to take to accomplish this? (Select two. Each option is part of a complete solution.)

Configure VLAN membership so that the Windows 2000 workstations are on their own VLAN.

Your organization uses a time-keeping application that only runs on Windows 2000 and does not run on newer OS versions. Because of this, there are several Windows 2000 workstations on your network. Last week you noticed unusual activity on your network coming from the Windows 2000 workstations. After further examination, you discover that the Windows 2000 workstations were the victim of a malicious attack and were being used to infiltrate the network. You find out that the attackers were able to gain access to the workstations because of the legacy operating system being used. The organization still needs to use the Windows 2000 workstations, which need to be connected to the internet, but you want to make sure the network is protected from future events. Which solution should you implement to protect the network while also allowing operations to continue as normal?

The wireless TV system

Your organization uses an 802.11b wireless network. Recently, other tenants installed the following equipment in your building: A wireless television distribution system running at 2.4 GHz A wireless phone system running at 5.8 GHz A wireless phone system running at 900 MHz An 802.11a wireless network running in the 5.725 - 5.850 GHz frequency range An 802.11j wireless network running in the 4.9 - 5.0 GHz frequency range Since this equipment was installed, your wireless network has been experiencing significant interference. Which system is to blame?

Storage segmentation

Your organization's security policy specifies that, regardless of ownership, any mobile device that connects to your internal network must have remote wipe enabled. If the device is lost or stolen, then it must be wiped to remove any sensitive data from it. Which of the following should you implement to ensure organizational data can be remote wiped while preserving personal data?

Double the bandwidth assigned per channel to 40 MHz.

Your wireless network consists of multiple 802.11n access points that are configured as follows: SSID (hidden): CorpNet Security: WPA2-PSK using AES Frequency: 5.7 GHz Bandwidth per channel: 20 MHz This network is required to support an ever-increasing number of devices. To ensure there is sufficient capacity, you want to maximize the available network bandwidth. What should you do?

Implement antenna diversity.

Your wireless network consists of multiple 802.11n access points that are configured as follows: SSID (hidden): CorpNet Security: WPA2-PSK using AES Frequency: 5.75 GHz Bandwidth per channel: 40 MHz Because of the unique construction of your organization's facility, there are many locations that do not have a clear line of sight between network clients and access points. As a result, radio signals are reflected along multiple paths before finally being received. The result is distorted signals that interfere with each other. What should you do?

412 meters

our network follows the 100BaseFX specifications for Fast Ethernet and uses half-duplex multi-mode cable. What is the maximum cable segment length allowed?
