A large enterprise customer has a single router that uses two active/active 10-Mbps internet links in one of its
offices. Each link currently handles approximately 7 Mbps of traffic, which is close to the full link capacity.
When a link fails, the failure leads to significantly degraded performance of all applications. Static routing is
used. The current ISP cannot deliver additional bandwidth capacity on the existing links. The customer needs
a network design that is resistant to failure, but does not increase CAPEX. Which solution should be proposed
to the customer?
A large enterprise cloud design team is evaluating different cloud consumption models. What is an example of typical PaaS limitations or concerns that should be considered during service design?
A network hacker is trying to interrupt the transport packet on IPSEC. A packet with duplicate sequence numbers is introduced. The customer sends high-priority traffic during this window. Which design parameter should be considered to mitigate this issue?
Network changes because of mergers, acquisitions, and divestment can be very disruptive to the network if not carried out carefully. When an organization sells parts of its business, it must detach the affected parts of the network from the rest of the network. Which network design approach is appropriate to minimize the impact and risks as the divested parts of the network are detached?
Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe. In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?
