172.16.10.0/24 network translate to?

42、An architect must design a topology for a WAN network that satisfies these requirements:
– Devices must be able to make informed decisions.

– Backup paths must always be available.
Which topology must the architect select?

43、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?

44、An architect must design an IPv6 migration solution for a corporation with remote offices to support:
– The customer has IPv4 peering with their service provider.
– IPv6 users need access to IPv4 and IPv6 resources.
– Existing content providers will migrate to IPv6 in the next two
years.
– Users will be migrated in a phase-by-phase approach.
Which migration solution must the architect choose?

Refer to the exhibit. A network engineer must design a BGP solution based on:
The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
The route reflector must have full redundancy and avoid a single point of failure.
R2 to R1 link utilization is 90%. and the remaining links are less than 50% utilized.
Which two solutions must the design Include? (Choose two.)

47、Drag and drop the descriptions from the left onto the categories they apply to on the right.

48、

Refer to the exhibit. A network engineer must design a BGP solution based on:

* R2 to R1 link utilization is 90%. and the remaining links are less than 50% utilized.
Which two solutions must the design Include? (Choose two.)

49、Refer to the exhibit.

An architect must design an IPv6 migration solution for an enterprise customer to support these requirements:
* Clients will transition to the new IPv6 network, which provides NAT64 and IPv6 DNS resolution services, using the same DNS name that points to the IPv4 address.
* The service provider will create a client-facing IPv6 interface with a new IPv6 virtual address that points to the same IPv4 DNS server.
* The service provider will support clients that use global IPv6 addresses and encapsulate IPv4 packets into IPv6 tunnels.
Which two migration solutions must the architect choose? (Choose two.)

51、Refer to the exhibit.

Area 10 is a regular OSPF area and networks 10.1.1.0/24 and 172.16.1.0/24 are internal. Which design provides optimal routing between both networks when the link between routers C and E fails?

52、Refer to the exhibit.

A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?
