Scenario: A Citrix Architect is asked by management at the Workslab organization to review their existing configuration and make the necessary upgrades. The architect recommends small changes to the pre-existing NetScaler configuration. Currently, the NetScaler MPX devices are configured in a high availability pair, and the outbound traffic is load-balanced between two Internet service providers 9ISPs) . However, the failover is NOT happening correctly. The following requirements were discussed during the design requirements phase: The return traffic for a specific flow should be routed through the same path while using Link Load Balancing. The link should fail over if the ISP router is up and intermediary devices to an ISP router are down. Traffic going through one ISP router should fail over to the secondary ISP, and the traffic should NOT flow through both routers simultaneously. What should the architect configure with Link Load balancing (LLB) to meet this requirement?

Scenario: Based on a discussion between a Citrix Architect and a team of Workspacelab members, the MPX Logical layout for Workspacelab has been created across three (3) sites. They captured the following requirements during the design discussion held for a NetScaler design project: All three (3) Workspacelab sites (DC, NDR, and DR) will have similar NetScaler configurations and design. Both external and internal NetScaler MPX appliances will have Global Server Load Balancing (GSLB) configured and deployed in Active/Passive mode. GSLB should resolve both A and AAA DNS queries. In the GSLB deployment, the NDR site will act as backup for the DC site, whereas the DR site will act as backup for the NDR site. When the external NetScaler replies to DNS traffic coming in through Cisco Firepower IPS, the replies should be sent back through the same path. On the internal NetScaler, both the front-end VIP and backend SNIP will be part of the same subnet. The external NetScaler will act as default gateway for the backend servers. All three (3) sites, DC, NDR, and DR, will have two (2) links to the Internet from different service providers configured in Active/Standby mode. Which design decision must the architect make the design requirements above?
