You are planning a leaf and spine topology for a data center. The campus is in a different</p><p>building; the customer wants to connect the campus network directly to the data center network.</p><p>To which data center switch or switches do you connect the campus core switches?</p><p>A. To two service leaf switches, which are dedicated to connecting the spine and leaf topology</p><p>to external networks</p><p>B. To two L3 edge switches, which are dedicated to connecting the spine and leaf topology to</p><p>external networks</p><p>C. To two border leaf switches, which are dedicated to connecting the spine and leaf topology to</p><p>external networks</p><p>D. To two L2 edge switches, which are dedicated to connecting the spine and leaf topology to</p><p>external networks</p><p>Answer: C</p><p>9. A customer currently has a three-tier architecture in which aggregation switches are the</p><p>default gateways. Pairs of aggregation switches use VRRP. You are migrating to an L2 two-tier</p><p>3 / 6</p><p>architecture in which the core switches are the default gateways.</p><p>How should you migrate the default gateway functionality?</p><p>A. Use a DHCP server to assign servers new gateway IP addresses, which are configured on</p><p>the new core switches</p><p>B. Configure VSX active gateway on the new core switches using the current default gateway IP</p><p>address as the virtual IP and a new virtual MAC address</p><p>C. Add the core switches to the aggregation switches’ VRRP groups and use VRRP to fail over</p><p>to the new switches</p><p>D. Configure VSX active gateway on the new core switches using a new default gateway IP</p><p>address as the virtual IP and the existing VRRP MAC for the virtual MAC address</p><p>Answer: C</p><p>10. In which situation do you need to select switches with a back-front (BF) airflow?</p><p>A. The switches are core switches in a dedicated rack with their ports facing the cold aisle</p><p>B. The switches are ToR switches which will have the port side facing the opposite way as</p><p>server ports</p><p>C. The switches are middle of the rack switches with their ports facing the cold aisle</p><p>D.

In ToR or Middle of Rack switch?Ports oriented to server ports:</p><p>A. The airflow of the switches should be back to front (BF)</p><p>B. The airflow of the switches should be front to back (FB)</p><p>C. It does not matter which direction is the airflow</p><p>D. It is recommended to use fanless Data Center Switches to overcome the heat generated</p><p>Answer: A</p><p>14.
