• Question 3:

  Which subnet address and mask would you use for all Class D multicast addresses to be matched within an access list?

  A. 224.0.0.0/20
  B. 224.0.0.0/4
  C. 239.0.0.0/24

• Question 4:

  WAN backup over the Internet is often used to provide primary connection redundancy. Which is the most important consideration when passing corporate traffic over the public Internet?

  A. security
  B. static versus dynamic routing
  C. bandwidth
  D. QoS
  E. latency
  A. security

  WAN Backup over the Internet Another alternative for WAN backup is to use the Internet as the connectivity transport between sites. However, keep in mind that this type of connection does not support bandwidth guarantees. The enterprise also needs to work closely with the ISP to set up the tunnels and advertise the company's networks internally so that remote offices have reachable IP destinations. Security is of great importance when you rely on the Internet for network connectivity, so a secure tunnel using IPsec needs to be deployed to protect the data during transport.

• Question 5:

  What three considerations should be taken into account when selecting a routing protocol? (Choose three.)

  A. classful routing
  B. scalability
  C. default route origination
  D. multi vendor support
  E. link load balancing
  F. hop count
  B. scalability
  D. multi vendor support
  E. link load balancing

• Question 6:

  When selecting which hardware switches to use throughout an enterprise campus switched network, which consideration is not relevant?

  A. whether data link layer switching based upon the MAC address is required
  B. the number of shared media segments
  C. which infrastructure service capabilities are required
  D. whether to support Layer 3 services at the network edge
  B. the number of shared media segments

  Shared media are not used in modern networks; all links are operating full-duplex Link: http://www.cisco.com/en/US/docs/solutions/Enterprise/ Campus/campover.html

• Question 7:

  What is the acceptable amount of one-way network delay for voice and video applications?

  A. 300 bytes
  B. 1 sec
  C. 150 ms
  D. 500 ms
  C. 150 ms

  ---

  Delay Components in VoIP Networks The ITU's G.I 14 recommendation specifics that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. In private networks, somewhat longer delays might be acceptable for economic reasons. The ITU G.114 recommendation specifics that 151-ms to 400-ms one-way delay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays of above 400 ms are unacceptable for general network planning purposes.

• Question 8:

  A customer requests a filtering design based on the need to scan all internet traffic, including remote workers. What solution meets these requirements?

  A. Cisco Cloud Web Security
  B. Cisco Network Admission Control
  C. Cisco Identity Services Engine
  D. Cisco Adaptive Security Appliance
  A. Cisco Cloud Web Security

• Question 9:

  A company wants to use private IP addresses for all its internal hosts. Which technology can the company use to provide access to the Internet using a single public IP address?

  A. static NAT
  B. source routing
  C. ACL
  D. PAT
  D. PAT

• Question 10:

  A circuit order has been placed for Gigabit Ethernet and is 80KM from the carrier equipment. What type of SFP will be required?

  A. TX
  B. SX
  C. ZX
  D. LX
