NEW QUESTION # 28
A company plans to transition to IPv6. They will link their IPv4 addresses to the lowest significant bits of the new Ipv6 addresses. A network administrator with an employee id: 4264:42:116 is preparing a mapping schema for the new IPv6 addresses. Which address does the 172.16.10.0/24 network translate to?
Answer: B
Explanation:
" link their IPv4 addresses to the lowest significant bits " This can never be a /64 network but must me a /120 network.
NEW QUESTION # 29 
Refer to the exhibit. A customer is planning to onboard three new VPN partner connections in the data center.
The new subnets must not overlap with the existing data center network, and the subnet size must not be bigger than necessary. The customer dedicated 10.1.8.0/21 for this design. Ho 1 // must the subnets be divided to meet these requirements?
Answer: A
Explanation:
Option B is retained because the subnetting task depends on the exhibit options and the chosen plan must divide 10.1.8.0/21 into nonoverlapping partner VPN subnets without allocating more address space than required. The design principle is variable-length subnet masking: allocate the smallest subnet that satisfies each partner requirement, then place the subnets on valid prefix boundaries inside the reserved aggregate.
Cisco addressing design emphasizes conserving address space, avoiding overlap, and preserving summarization where possible. A /21 provides 2048 total addresses, so the designer can carve several smaller partner ranges while keeping the entire allocation summarizable as 10.1.8.0/21 toward the data-center core.
Incorrect options would either waste addresses, overlap existing ranges, place subnets on invalid boundaries, or allocate blocks larger than necessary. Option B is the mapping that satisfies the exhibit constraints while keeping the design clean for routing, firewall policy, and VPN onboarding. Reference topics: IPv4 VLSM, subnet boundary alignment, partner VPN addressing, summarization, nonoverlapping address design.

NEW QUESTION # 31
An architect must design a network solution for a regional medical center that will provide interconnectivity between regionally dispersed data centers and a new colocation. The design must:
* utilize point-to-point connectivity
* utilize existing VLAN infrastructure
* increase performance for data center synchronization and backup processes
* reduce configuration complexity
Which solution must the engineer choose?
Answer: B
Explanation:
L2VPN is the correct solution because the customer requires point-to-point connectivity while preserving existing VLAN infrastructure. Cisco describes Layer 2 VPN services as emulating Layer 2 connectivity across a provider IP or MPLS backbone, commonly through Ethernet pseudowires or VPWS. This allows sites such as dispersed data centers and a colocation facility to exchange Ethernet frames as if they were directly connected at Layer 2. The design is especially useful when data center synchronization, backup workflows, or application dependencies require VLAN continuity or minimal changes to existing addressing and routing. L3VPN would provide routed connectivity and VRF separation, but it would not preserve the VLAN-based service model. GRE would add an overlay tunnel but would not natively provide provider- managed Layer 2 service. DMVPN is designed for scalable Layer 3 IPsec/GRE overlays between branches, not for VLAN extension or point-to-point data center interconnect. Reference topics: L2VPN, VPWS, Ethernet pseudowire, VLAN extension, data center interconnect, WAN service design.
NEW QUESTION # 32
An engineer must propose a solution for a campus network that includes the capability to create multiple Layer
3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding.
The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?
Answer: C
Explanation:
Section: WAN for Enterprise Networks
