NEW QUESTION # 256
Company XYZ has 30 sites running a legacy private WAN architecture that connects to the Internet via multiple high-speed connections. The company is now redesigning their network and must comply with these design requirements:
* Use a private WAN strategy that allows the sites to connect to each other directly and caters for future expansion.
* Use the Internet as the underlay for the private WAN.
* Securely transfer the corporate data over the private WAN.
Which two technologies should be incorporated into the design of this network? (Choose two.)
Answer: A,B
Explanation:
* B (IPsec): Provides encryption over the public Internet for secure data transfer.
* C (DMVPN): Creates a dynamic, scalable private WAN overlay across the Internet allowing direct site- to-site connectivity.
Why other options are incorrect:
* A: S-VTI requires more static configuration and lacks DMVPN's scalability.
* D: GET VPN is best for MPLS/private WAN, not Internet underlays.
* E: PPTP is outdated and insecure.

NEW QUESTION # 258
Which function is performed at the access layer of the three-layer hierarchical network design model?
Answer: E
Explanation:
In the Cisco three-layer hierarchical design model (Access, Distribution, Core), the access layer is primarily responsible for:
* Providing user/device connectivity.
* Enforcing policy boundaries.
* Performing QoS classification and marking at ingress.
The access layer is the optimal point to classify and mark traffic for QoS because:
* It is the first point of entry into the network for end-user devices.
* Markings can then be trusted by upstream devices (distribution and core).
* This minimizes trust boundaries throughout the network and ensures consistent policy enforcement.
This design principle ensures end-to-end QoS consistency, a key objective emphasized in CCDE v3.1 for scalable and maintainable enterprise designs.
Why other options are incorrect:
* A (Fault isolation): Typically handled at distribution/core layers.
* C (Reliability): A general network-wide requirement, not specific to access.
* D (Fast transport): Primarily a core layer function.
* E (Redundancy and load balancing): Managed primarily at distribution and core layers.
