56. A client is establishing a TCP session with a server. How is the acknowledgment number in the response segment to the client determined?
The acknowledgment number field is modified by adding 1 to the randomly chosen initial sequence number in response to the client.* The acknowledgment number is set to 11 to signify an acknowledgment packet and synchronization packet back to the client.

64. How could a faulty network device create a source of hazard for a user? (Choose two.)
It could stop functioning.* It could apply dangerous voltage to other pieces of equipment. It could explode.* It could produce an unsafe electromagnetic field. It could apply dangerous voltage to itself.
65. What are three important considerations when planning the structure of an IP addressing scheme? (Choose three.)
preventing duplication of addresses* providing and controlling access* documenting the network monitoring security and performance conserving addresses* implementing new services

DNS servers can cache recent queries to reduce DNS query traffic.*
DNS servers are programmed to drop requests for name translations that are not within their zone.
All DNS servers must maintain mappings for the entire DNS structure.
DNS relies on a hub-and-spoke topology with centralized servers.
