NEW QUESTION # 105
Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A's network, both companies use overlapping IP address ranges. Which action conserves IP address space and provides access to the server?
Answer: A
NEW QUESTION # 106 
Refer to the exhibit. An engineer must ensure that the QoS design guarantees bandwidth for the applications, and an application can request a particular type of service to support its delay requirements. Which solution must the engineer select?
Answer: C
NEW QUESTION # 107
A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DM VPN back to the hub with two 10-Mbps internet connections. The branch routers are multivendor and have limited memory and CPU resources. Which routing protocol and design solution meets the requirements?
Answer: B
Explanation:
OSPF with the hub in area 0 and branch routers in stub areas with ECMP is the best fit because the customer has multivendor branch routers with limited memory and CPU. EIGRP is not suitable in this case because the branch environment is multivendor and EIGRP is not the safest open-standard design choice for broad interoperability. IS-IS can be efficient, but it is less common for small DMVPN branch deployments and the option does not address the requirement for resource-constrained branch routing. eBGP route reflection is not technically correct, because route reflectors are an iBGP scaling mechanism. OSPF provides an open-standard dynamic routing solution, and placing branches in stub areas limits the amount of external routing information that low-resource branch routers must process. ECMP allows both equal 10-Mbps DMVPN paths to be used when equal-cost paths exist. This design reduces operational overhead compared with static routing while respecting the platform constraints at the spokes. Reference topics: OSPF branch design, stub areas, ECMP, DMVPN routing, multivendor interoperability, branch resource optimization.
NEW QUESTION # 108
Refer to the exhibit. Currently the network uses a single-homed solution for connecting to the internet. An engineer must design a more resilient WAN using the internet circuits at each site.
The design must provide failover connectivity, support load-sharing of traffic, and QoS. Which solution must the engineer choose?
Answer: D
NEW QUESTION # 109
An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this area. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?
Answer: B
Explanation:
LSA type1 + type2 + Defaut required to minimise Router resources utilization -> total stub area.
