NEW QUESTION # 339
Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)
Answer: A,B
NEW QUESTION # 340
Refer to the exhibit.
Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?
Answer: B
NEW QUESTION # 341
Which OSPF area blocks LSA Type 3, 4 and 5, but allows a default summary route?
Answer: A
Explanation:
A totally stubby area does not flood network summary LSAs (Type 3). It stifles Type 4 LSAs, as well. Like regular stub areas, totally stubby areas do not flood Type 5 LSAs. A totally stubby area sends just a single LSA for the default route.

NEW QUESTION # 343
A customer ' s current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
* reduce the impact of topology changes
* reduce the time spent on network administration
* reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)
Answer: B,C
Explanation:
Rapid PVST+ and VTP address the stated redesign goals. Moving from IEEE 802.1D STP to Rapid PVST+ reduces the impact of topology changes because rapid spanning tree provides faster convergence through proposal/agreement behavior and faster port-role transitions. That improves availability compared with classic STP timers. VTP reduces administrative effort and manual configuration errors by centrally propagating VLAN information across switches in the same VTP domain. It can also support pruning so unused VLAN traffic is not unnecessarily carried across trunks. MST could reduce spanning-tree instance count, but the question emphasizes reducing topology-change impact and reducing manual VLAN configuration work; Rapid PVST+ plus VTP addresses both directly. Storm control helps limit broadcast and multicast traffic but does not solve STP convergence or VLAN administration. Dynamic Trunking Protocol negotiates trunk state; it does not propagate VLAN information and is often avoided in deterministic campus designs. In production, VTP should be used carefully with version control, domain/password discipline, and change governance because incorrect VTP configuration can have broad impact. Reference topics: Rapid PVST+, STP convergence, VTP, VLAN pruning, campus Layer 2 operations.
NEW QUESTION # 344
