NEW QUESTION # 451
You want to add 900 VLANs to an existing 90 in a data center. What are two spanning tree concerns to consider?
Answer: B,C
Explanation:
# Explanation:
B: Cisco switches reserve certain VLAN IDs. VLANs beyond 1005 are considered extended VLANs and may require special configuration (e.g., VTP transparent mode).
D: Each VLAN with PVST+ has its own instance of STP. Adding 900 more VLANs significantly increases the STP processing overhead on the switch's control plane and CPU.
Other options:
A: STP convergence time is more dependent on topology than VLAN count.
C: STP diameter is unrelated to the number of VLANs-it ' s a function of hops in the topology.
E: BPDU handling is VLAN-aware under PVST+; there's no direct per-BPDU VLAN limitation.

Which service abstracts away the management of the operating system, middleware, and runtime?
Answer: D
NEW QUESTION # 453
Traditionally, networks handled static web pages, e-mail, and routine client/server traffic. Today, enterprise networks must handle more sophisticated types of network applications that include voice and video. Applications place increasing demands on IT infrastructures as they evolve into highly visible services that represent the face of the business to internal and external audiences.
The large amount and variety of data requires that the modern network be aware of the content carried across it to optimally handle that content.
Which service provide this intelligence?
Answer: B
Explanation:
Application networking services provide content awareness in the network, enabling optimization and control for applications such as voice, video, and other advanced services. This intelligence allows the network to handle application demands efficiently and align with business needs.
NEW QUESTION # 454
Refer to the exhibit. Company XYZ must design a DMVPN tunnel between the three sites.
Chicago is going to act as the NHS and the company wants DMVPN to detect peer endpoint failures. Which technology should be used in the design?
Answer: A
NEW QUESTION # 455
According to the CIA triad principles for network security design, which principle should be priority for a Zero Trust network?
Answer: A
Explanation:
* A (Encryption + strong authentication) aligns most closely with Zero Trust's emphasis on always verifying identity and protecting data as it moves across untrusted networks.
* Data-in-motion encryption ensures confidentiality, and two-factor authentication ensures strict identity verification.
Why other options are incorrect:
* B: Data-at-rest encryption is important but not as critical as controlling data in motion for Zero Trust.
* C: Categorization helps in segmentation but is not the core Zero Trust principle.
* D: High availability is a design requirement, not the primary Zero Trust security control.
