1Y0-740 Exam Training Practice Tests (Citrix WANScaler 4.2: Administration)]

Question 1

Which TCP variant would be appropriate in an environment where a site is connected to multiple WAN links, each of which has no guaranteed bandwidth?

A. Inline B. Full bandwidth C. Softboost D. Variable E. Hardboost

Correct Answer: C

Question 2

Which three of the listed combinations are valid? (Choose three.)

A. Memory-based and disk-based compression with flow control B. Partial bandwidth and hardboost C. Disk-based compression without flow control D. Softboost and hardboost E. Memory-based compression with flow control

Correct Answer: A,B,E

Question 3

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

Correct Answer: B,C,D,G

Question 4

Scenario: An administrator is instructed to implement two WANScaler appliances in high availability mode for a virtual inline deployment. In this environment, the switches and routers are already connected. What is the minimum number of Ethernet cables required to set up the WANScaler appliances in a single LAN, single WAN deployment?

A. 4 B. 2 C. 1 D. 3

Correct Answer: B

Question 5

A company has offices in New York, Los Angeles, London and Beijing, with 1,000 remote employees working worldwide. How many WANScaler Controllers are required to support a WANScaler Client deployment in this environment?

A. 4 B. 2 C. 1 D. 3

Correct Answer: C

Question 6

Scenario: A System Administrator is attempting to configure a QoS solution for a routine file transfer that is critical to the organization. The file is transferred using FTP and it is important that no other traffic suppresses the transfer to less than 20% of the bandwidth limit. In addition, all queues must be named appropriately. Which three steps should the administrator take to meet the requirements of this scenario? (Choose three.)

A. Change the bandwidth allocation of "Queue B" from 0% to 20% and change the bandwidth allocation of "Queue A" from 100% to 80%. B. Change the name of Queue B to "FTP." C. Update the FTP Data service class QoS from "Queue A" to "FTP." D. Change the bandwidth allocation of "Queue A" from 0% to 20% and change the bandwidth allocation of "Queue B" from 100% to 80%. E. Assign the "FTP" queue, in megabytes, 20% of total available bandwidth. F. Create a queue and name it "FTP."

Correct Answer: A,B,C

Question 7

Scenario: An administrator is analyzing the sending and receiving usage graphs of the respective WANScaler appliances on each end of a point-to-point link with a dedicated circuit between them and notices that there is a difference between each of these graphs.
Click the 'Exhibit' button to view the usage graph of the sending-side WANScaler appliance.
Which statement describes the troubleshooting information that the administrator needs to consider based on these differences?

A. Accelerated Line Usage can potentially be very different between two WANScaler appliances based on the PMTU discovery and associated TCP fragmentation of the sending-side WANScaler appliance. B. Accelerated Goodput, which includes TCP headers, should be identical between the two graphs given that there is not a third WANScaler appliance transferring data to either one. C. Accelerated Line Usage can potentially be very different between two WANScaler appliances based on the fact that packet losses are seen by the sender-side WANScaler appliance but not the receiver-side one. D. Non-accelerated traffic, which does not include any TCP-based traffic, will be entirely different between the two WANScaler appliances unless the non-accelerated traffic happens to flow through both of them.

Correct Answer: C

Question 8

Which two interfaces are required to support acceleration in an inline mode configuration?
(Choose two.)

A. apA.2 B. apA.0 C. Eth1 D. apA.1 E. Eth0

Correct Answer: A,D

Question 9

Scenario: A humanitarian organization is delivering food supplies to a disaster area, and the logistic team needs access to a database at their headquarters in order to determine the food supply inventory. The network traffic from the disaster area to the headquarters is TCP-based. The Network Administrator has been instructed to ensure, if the requirement exists, that the TCP accelerated traffic in this environment has access to 90% of the 1.5 Mbps WAN link.
Which bandwidth management rate will ensure that 90% of the bandwidth is assigned to accelerated traffic regardless of packet loss?

A. Full bandwidth B. Softboost C. Partial bandwidth D. Hardboost

Correct Answer: D

Question 10

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

Correct Answer: D
