Citrix WANScaler 4.2: Administration Sample Questions:

1. Which two non-proprietary, licensed compression algorithms does the WANScaler appliance use? (Choose two.)

A) ZLIB
B) LZS
C) JPEG
D) GZIP

2. Scenario: A system administrator deployed a WANScaler 8500 appliance at one branch office and a WANScaler 8800 appliance at the headquarters office. Given the nature of the data transfers that are routinely used between the two offices (including database replication, multiple file transfers and directory synchronization), the administrator decides to use disk-based compression.
After several days of testing, the administrator could not explain why the compression ratio was below the expected level.
What are four possible reasons why the compression ratio was below the expected level?
(Choose four.)

A) The WANScaler 8500 appliance does not support disk-based compression.
B) File types with little to no redundancy will not compress well.
C) Compressibility of data is affected by the application protocol used.
D) Compression ratios are data-dependent.
E) WANScaler appliances must be deployed as matched pairs.
F) Encryption of the data has a negative effect on compressibility.
G) The WANScaler is not suited for compressing CIFS traffic.

3. An administrator configured a WANScaler appliance to accelerate FTP traffic between specific sites. Which method should the administrator use to test the configurations to ensure that the FTP traffic is being accelerated?

A) Check the Service Class Statistics page.
B) Check the usage graph to see if TCP traffic is being accelerated.
C) Ping the FTP server to see if there is a connection to it.
D) Perform a packet capture at the endpoint workstation.

4. From the Compressibility Graph in the Monitoring Service Class Statistics page, an administrator can obtain details of the amount of data __________. (Choose the correct phrase to complete the sentence.)

A) before compression on all the service classes
B) before and after compression on the top compressible service classes
C) after compression on all the service classes
D) after compression on the top compressible service classes

5. Scenario: An administrator designing a WANScaler implementation would like the implementation to be set up based on the following considerations:
1.The data center supports multiple branch offices, of which only one has a WANScaler appliance.
2.The branch office WANScaler appliance should connect directly to the WAN router for the branch office.
3.The headquarters WANScaler appliance should connect directly to the WAN router for the headquarters.
4.All traffic from the branch office to servers at the headquarters should flow through the branch office WANScaler appliance.
Which WANScaler deployment topology should be used in this type of implementation?

A) Token Ring
B) Hub-and-spoke
C) Star
D) Point-to-point
