第2题：

Your company has two data centers.  Each data center contains a perimeter network.  Your network contains an Exchange Server 2010 organization.  You plan to deploy Exchange Server 2010 Edge Transport servers in the perimeter networks.  You need to recommend a solution for the Edge Transport servers that meets the following requirements：.Distribute inbound e-mail messages across all Edge Transport servers  .Ensure that users receive inbound e-mail messages if an Edge Transport server fails  .Ensure that users receive inbound e-mail messages if a single data center network becomes unavailable .Minimize costs  What should you recommend？（）

  • A、In each perimeter network， deploy one Edge Transport server. Implement failover clustering.
  • B、In each perimeter network， deploy two Edge Transport servers. Implement failover clustering.
  • C、In each perimeter network， deploy one Edge Transport server. Configure a mail exchange （MX） record for each server.
  • D、In each perimeter network， deploy two Edge Transport servers. Configure a mail exchange （MX） record for each server.

第3题：

单句理解

听力原文：The interest rates on these small deposits are usually floating rates, and they are usually 2%- 5% below the bank's current base rates.

(1)

A．Bank's current base rates are higher than those on small deposits.

B．Bank's current base rates are lower than those on small deposits.

C．Bank's current base rates are not floating rates.

D．Bank's current base rates are usually floating rates.


正确答案：A
解析：根据录音原文可知，The interest rates on these small deposits为浮动汇率，而不是the bank's current base rates，而且要比银行当前的基准汇率低。

第4题：

Which two statements are correct regarding multicast implementation using a WLAN controller (v5.2) and AP?（）

  • A、Multicast traffic is sent out on Cisco APs at the highest mandatory data rate.
  • B、Multicast traffic is sent out on Cisco APs at the highest supported data rate.
  • C、On Cisco APs， multicast traffic and beacons are sent out at the same data rates to maintain a common  cell size for normal data as well as multicast data.
  • D、If there is more than one mandatory data rate， multicast traffic will be sent at the highest mandatory rate  and beacons will be sent at the lowest mandatory rate.
  • E、On Cisco APs， multicast traffic will be sent out at the highest data rate that a client can maintain with the  AP.
