  • It can only filter packets based on limited Layer 3 and 4 information.

Pregunta 8

Pregunta
Which impact does adding a Layer 2 switch have on a network?
Respuesta

  • an increase in the size of the broadcast domain
  • an increase in the size of the collision domain
  • an increase in the number of network collisions

Pregunta 9

Pregunta
Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)
Respuesta
  • The source port field identifies the running application or service that will handle data returning to the PC.
  • The UDP destination port number identifies the application or service on the server which will handle the data.
  • UDP segments are encapsulated within IP packets for transport across the network.
  • TCP is the preferred protocol when a function requires lower network overhead.
  • The TCP source port number identifies the sending host on the network.
  • The TCP process running on the PC randomly selects the destination port when establishing a session with the server.

  • limiting the read access to specific fields of a table or joins of tables
  • using stored procedures with the “db_owner” default role
  • assigning DBA or admin access rights to the application account

Pregunta 14

Pregunta

Respuesta
  • stateful firewall
  • forward proxy
  • reverse proxy
  • jump box

Pregunta 15

Pregunta
What is a characteristic of a virtual machine running on a PC?
Respuesta
  • A virtual machine needs a physical network adapter to connect to the Internet.
  • A virtual machine runs its own operating system.
  • The number of virtual machines that can be made available depends on the software resources of the host machine.
  • A virtual machine is not susceptible to threats and malicious attacks.

Pregunta 16

Pregunta

Respuesta
  • True
  • False

Pregunta 17

Pregunta
What is a characteristic of the blue-green upgrade deployment strategy?
Respuesta
  • A new environment is created with the new code in it, while the old environment is held in reserve in case users experience problems.
  • The code changes are periodically rolled out in such a way that they do not impact current users.
  • The new code is deployed all at once to the old environment. If users experience no issues, it is then moved to the new environment.
  • The new code version is first rolled out to a subset of users. Changes can then be rolled back if the users experience any problems.
