NEW QUESTION # 120
Refer to the exhibit.
A customer is running HSRP on the core routers. Over time the company has grown and requires more network capacity. In the current environment, some of the downstream interfaces are almost fully utilized, but others are not. Which solution improves the situation?
Answer: A
NEW QUESTION # 121
Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time.
Which solution must the design include?
Answer: A
NEW QUESTION # 122
An architect is designing a connectivity solution for a customer ' s two small branch offices. The customer wants a cost-effective design, no routing overload, and some down time during the year is acceptable. Which connectivity solution must the architect choose?
Answer: A
Explanation:
A single-homed WAN design is appropriate for two small branch offices when cost is the main concern, routing overload must be avoided, and occasional downtime is acceptable. Single-homed connectivity uses one WAN connection from the branch to the provider or headquarters. It is the simplest and least expensive model because it minimizes circuits, routers, routing adjacencies, and failover complexity. Dual-homed or multihomed designs improve availability, but they add cost and operational overhead through additional links, devices, routing policy, and monitoring. Dual multihomed designs are the most resilient but clearly exceed the requirement for a small cost-sensitive branch. A single multihomed design provides some provider or link diversity, but it is still more complex than necessary if the customer accepts some downtime. In Cisco WAN design, the correct topology must match the business availability requirement; not every site justifies redundant circuits. Reference topics: WAN topology selection, single-homed branch design, cost versus availability, routing simplicity, branch connectivity.
NEW QUESTION # 123
Which two functions is the Cisco SD-Access Border Node responsible for? (Choose two.)
Answer: C,E
NEW QUESTION # 124
A company's security policy requires that all connections between sites be encrypted in a manner that does not require maintenance of permanent tunnels. The sites are connected through a private MPLS-based service that uses a dynamically changing key and spoke-to-spoke communication. Which type of transport encryption must be used in this environment?
Answer: A
Explanation:
GETVPN (Group Encrypted Transport VPN) is a Cisco proprietary technology that provides dynamic encryption for spoke-to-spoke communication over a private MPLS network. It does not require the maintenance of permanent tunnels, and it uses dynamically changing keys.
DMVPN (Dynamic Multipoint VPN) is another Cisco proprietary technology that can be used to create a VPN over a private MPLS network. However, DMVPN does require the maintenance of permanent tunnels, and it does not support dynamically changing keys.
GRE VPN (Generic Routing Encapsulation VPN) is a generic VPN technology that can be used over any type of network, including a private MPLS network. However, GRE VPN does not support dynamically changing keys.
Standard IPsec VPN is a generic VPN technology that can be used over any type of network, including a private MPLS network. It supports dynamically changing keys, but it requires the maintenance of permanent tunnels.
Therefore, the best choice for this environment is GETVPN. It meets all of the requirements, including dynamically changing keys, spoke-to-spoke communication, and no need for permanent tunnels.
