Cisco CCNA 200-301 Questions & Answers

• Question 1331:

  Which group of channels in the 802.11b/gin/ac/ax 2.4 GHz frequency bands are nonoverlapping channels?

  A. channels 1, 5, and 10

  B. channels 1, 6, and 11

  C. channels 1, 5, and 11

  D. channels 1, 6, and 10

  Correct Answer: B

• Question 1332:

  What is a function of Layer 3 switches?

  A. They route traffic between devices in different VLANs.

  B. They transmit broadcast traffic when operating in Layer 3 mode exclusively.

  C. They move frames between endpoints limited to IP addresses.

  D. They forward Ethernet frames between VLANs using only MAC addresses,

  Correct Answer: A

  They route traffic between devices in different VLANs.

• Question 1333:

  Which cable type must be used to interconnect one switch using 1000 BASE-SX GBIC modules and another switch using 1000 BASE-SX SFP modules?

  A. LC to SC

  B. SC to SC

  C. LC to LC

  D. SC to ST

  Correct Answer: A

  SFP is LC:

  all SFP and SFP+ optics require LC connectors so the question becomes when you need single mode fiber or multi mode fiber but the connectot type is clear. SC square connectors are too big to fit in a SFP or SFP+.

  GBIC is SC:

  GBIC is commonly used with Gigabit Ethernet and Fibre Channel. But its applications are not limited to these two types. There is also Fast Ethernet (FE) GBIC, BIDI GBIC, CWDM GBIC, DWDM GBIC, etc. Generally, GBIC is with the SC

• Question 1334:

  What is a benefit of a point-to-point leased line?

  A. low cost

  B. full-mesh capability

  C. simplicity of configuration

  D. flexibility of design

  Correct Answer: C

  Point-to-point leased line simplifies the configuration as the circuit is available on a permanent basis and does not require a connection to be set up before traffic is passed. It does not require to define a permanent virtual circuit (PVC) in the configuration either

• Question 1335:

  Which component controls and distributes physical resources for each virtual machine?

  A. hypervisor

  B. OS

  C. CPU

  D. physical enclosure

  Correct Answer: A

• Question 1336:

  What are two advantages of implementing a controller-based architecture instead of traditional network architecture? (Choose two.)

  A. It allows for seamless connectivity to virtual machines.

  B. It increases security against denial-of-service attacks.

  C. It supports complex and high-scale IP addressing schemes.

  D. It enables configuration task automation.

  E. It provides increased scalability and management options.

  Correct Answer: DE

• Question 1337:

  What is the purpose of the service-set identifier?

  A. It identifies the wireless network to which an application must connect.

  B. It identifies the wired network to which a network device is connected.

  C. It identifies the wired network to which a user device is connected.

  D. It identifies a wireless network for a mobile device to connect.

  Correct Answer: D

  The admins need to sort this out, would be useless without the knowlegable folk in the discussion section.

• Question 1338:

  How do UTP and STP cables compare?

  A. UTP cables provide faster and more reliable data transfer rates and STP cables are slower and less reliable.

  B. STP cables are shielded and protect against electromagnetic interference and UTP lacks the same protection against electromagnetic interference.

  C. STP cables are cheaper to procure and easier to install and UTP cables are more expensive and harder to install.

  D. UTP cables are less prone to crosstalk and interference and STP cables are more prone to crosstalk and interference.

  Correct Answer: B

• Question 1339:

  What are two disadvantages of a full-mesh topology? (Choose two.)

  A. It requires complex configuration.

  B. It needs a high MTU between sites.

  C. It works only with BGP between sites.

  D. It has a high implementation cost.

  E. It must have point-to-point communication.

  Correct Answer: AD
