An engineer must design a WAN solution so that ISP-1 is always preferred over ISP-2. The path via ISP-2 is considered as a backup and must be used only when the path to ISP-1 is down. Which solution must the engineer choose?
An architect is working on a design to connect a company's main site to several small to medium- sized remote branches. The solution must include redundant WAN links, but the customer has a limited budget and wants the ability to increase the link speed easily in the future. QoS will not on the branch routers so there is no need for consistent end-to-end QoS. Which solution does the architect propose?
When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.
* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.
* Download traffic must never experience a delay.
Which solution must the architect choose?
An engineer working for a service provider with an employee ID: 4859:86:437 must design a solution to provide remote connectivity over the public internet. The design must:
- securely connect multiple remote sites to the central site
- provide redundant paths to the central site
- allow auto path selection based on failure and connection quality
- support IP multicast
- minimal configuration at remote sites
Which solution must the engineer choose?
