Cisco Designing Cisco Enterprise Networks Sample Questions (Q322-Q327):

NEW QUESTION # 322
An architect is creating a migration strategy for a large organization in which the choice made by the application between IPv6 and IPv4 is based on the DNS request. Which migration strategy does the architect choose?

Answer: A


NEW QUESTION # 323

Refer to the exhibit A customer requires a Layer 2 network designed to support:
* 500 active logical ports
* trunking of 30 VLANs
* convergence of less than 1 second
Which Spanning Tree Protocol must be selected?

Answer: C

Explanation:
MSTP is the correct spanning-tree choice for a Layer 2 design with many logical ports, multiple trunked VLANs, and a subsecond convergence requirement. Rapid PVST+ provides rapid convergence, but it creates a separate spanning-tree instance for every VLAN. With 30 VLANs on trunks and hundreds of active ports, the number of logical STP ports can grow quickly and increase CPU and memory load. MSTP maps many VLANs into a smaller number of spanning-tree instances while still using rapid convergence behavior based on IEEE 802.1w principles. This makes it more scalable for large Layer 2 domains than PVST+ or Rapid PVST+ when many VLANs are present. CST provides a single instance but lacks the flexibility and convergence characteristics expected in modern enterprise designs. The design needs both scalability and fast convergence, and MSTP is the standards-based protocol that best satisfies both requirements. Reference topics: MSTP, Rapid STP, logical STP ports, VLAN-to-instance mapping, Layer 2 scalability, convergence.
