Braindumps for "920-448" Exam

Got it from ITCertkeys it is amazing site

 Question 1.

Answer: C

Question 3. is using Alteon 180E switches for Server Load balancing. The network contains
the following information:

What classification criteria will be used to meet this objective? (choose two.)

C. Virtual Server
D. Size of Frames

Answer: B, C

Question 5.'s network is connected to an Alteon Switch in turn is connected to an ISP router. The following information exists in the network

* subnet for all internal networks
* internet accessible web servers on this internal network with &
* static NAT for these two servers to NAT to &

The rest of the workstation are client workstation that are not accessed from the internet, but need to initiate connections to the internet and back. 

Which steps are required to achieve this configuration? (Choose four.)

* Each virtual server is taking an equal share of the bandwidth
* Alteon switches to provide redundancy.

Which configuration provides optimal performance?

A. RTSP and HTTP will not work through the same switch since RTSP user \s UDP.
B. Use VRRP Active-Active with sharing enable, all the switches providing services to all the 
     virtual servers.

     services, since mixing RTSP and HTTP traffic is not advisable.

This is know as what type of configuration?

B. Clustering
C. Management IP Address

A. the Alton Accelerator
B. the Alton Switched Firewall
C. the Checkpoint SMART TRACKER

B. /cfg/route/rip
C. /cfg/route/rip 1 or rip 2
D. /cfg/net/route/rip 1 or rip 2

Answer: B

Question 15.
A support engineer is tasked to troubleshoot a network consisting of an ASF 5010 Cluster of two
SFD's and two SFA's with 2.0 software running sync on Ethernet 2 between the two SFD's. the support engineer types in the info/clu command and notices synch errors.
