問題6

Scenario: A network engineer needs to re-configure the NetScaler to utilize two new VLANs - VLAN2 and VLAN3. VLAN2 is an untagged VLAN and VLAN3 will require a .1q compliant tag. Interface 1/1 is the only interface that will be used on the NetScaler.
How could the engineer configure the NetScaler so that it can communicate with both networks?

A. Enable the Tag all VLANs option on interface 1/1.

B. Add VLAN2 and bind interface 1/1 as untaggedAdd VLAN3 and bind interface 1/1 as tagged

C. Change the NSVLAN to 3Add VLAN 2 and bind interface 1/1 as untagged

D. Add a SNIP for each VLANEnable management access on the SNIP for VLAN3

正確答案: B

問題7

Scenario: An application that uses HTTP for connections and other protocols for different types of content has been deployed. Load balancing virtual servers have been created for each protocol and the engineer now needs to ensure that once a load balancing decision has occurred, further requests for different content are served from the same server.
How could the engineer achieve this?

A. Set the Spillover method to DYNAMICCONNECTION.

B. Add a new virtual server for each protocol that is not directly addressable.

C. Create a persistency group.

D. Set each virtual server to use Source IP Hash as the load balancing method.
