Refer to the exhibit. An architect is designing an IPv4 plan using the 172.16.0.0/16. The design must maximize the number of subnets while meeting these requirements:

500 hosts within the server room

100 hosts at the remote site

25 hosts at the access site

Which plan must the architect choose?

A)

B)

C)

D)

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

A customer requires QoS to support multimedia conferencing over MPLS. The network architect chooses to use per-hop behavior. Which solution must the architect use to classify and mark traffic traveling between branch sites?

Refer to the exhibit. An engineer is designing a BGP solution for a client that peers with ISP1 for full Internet connectivity and with ISP2 for direct exchange of routes for several third parties. Which action, when implemented on the edge routers, enables the client network to reach the Internet through ISP1?

Refer to the exhibit A network administrator plans to announce the site subnets to the WAN using route summarization instead of announcing every subnet. What is the smallest summary route that should be used to encompass all subnets at the site?

Which security functionality does gRPC provide?

Which design consideration should be observed when EIGRP is configured on Data Center switches?

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?

When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?

Refer to the exhibit. An architect is designing a hierarchical ISIS solution for a customer with these requirements:
