1Y0-740 無料問題集「Citrix WANScaler 4.2: Administration」
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?

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?

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?

Scenario: A SYN packet with a sequence number of 'A' is sent from a workstation to a local WANScaler appliance, forwarded across the WAN to a remote WANScaler appliance and then forwarded to the server. A packet with a sequence number of 'B' is sent from the server through the WANScaler appliances back to the workstation.

Scenario: An administrator configures bandwidth settings for a site after referring to the usage graph and finding that there is a significant gap between accelerated line usage and the accelerated data transferred. The administrator decides to test optimal data transfer rates between WANScaler appliances using iPerf. What must the administrator do in order to test end-to-end achievable bandwidth using iPerf?
