• Question 863:

  Which language can be used to model configuration and state data?

  A. JSON
  B. XML
  C. XDR
  D. YANG
  D. YANG

• Question 864:

  How does a router behave when configured with the default DNS lookup settings, and a URL is entered on the CLI?

  A. prompts the user to specify the desired IP address.
  B. initiates a pinfsfg request to the URL.
  C. continuously attxempts tos resolve the URL until the command is cancelled.
  D. attempts to query a DNS server on the network
  D. attempts to query a DNS server on the network

• Question 865:

  What is one difference between EIGRP and OSPF?

  A. OSPF is a Cisco proprietary protocol, and EIGRP is an IETF open standard protocol.
  B. OSPF uses the DUAL distance vector algorithm, and EIGRP uses the Dijkstra link-state algorithm
  C. EIGRP uses the variance command lot unequal cost load balancing, and OSPF supports unequal cost balancing by default.
  D. EIGRP uses the DUAL distance vector algorithm, and OSPF uses the Dijkstra link-state algorithm
  D. EIGRP uses the DUAL distance vector algorithm, and OSPF uses the Dijkstra link-state algorithm

  ---

  Explanation

  EIGRP is based on DUAL (Diffusing Update Algorithm) while OSPF uses Dijkstra's Shortest Path Algorithm with the major difference in how they calculate the shortest routing path. OSPF has capability to calculate the best shortest path to each reachable subnet/network using an algorithm called SFP (Shortest Path First) also known as Dijkstra algorithm. "Neighbor Table" that contain all discovered OSPF neighbour with whom routing information will be interchanged.

• Question 866:

  Which time protocol offers security features and utilizes site-local IPv6 multicast addresses?

  A. NTPv3
  B. PTP IEEE 1588v1
  C. NTPv4
  D. PTP IEEE 1588v2
  C. NTPv4

• Question 868:

  Refer to the exhibit. An engineer must configure static NAT on R1 lo allow users HTTP access to the web server on TCP port 80. The web server must be reachable through ISP 1 and ISP 2. Which command set should be applied to R1 to fulfill these requirements?

  

  A. ip nat inside source static tcp 10.1.1.100 80 209.165.200.225 80 extendableip nat inside source static tcp 10.1.1.100 80 209.165.201.1 80 extendable

  Explanation

  the "extendable" keyword should be added if the same Inside Local is mapped to different Inside Global Addresses (the IP address of an inside host as it appears to the outside network). An example of this case is when you have two connections to the Internet on two ISPs for redundancy. So you will need to map two Inside Global IP addresses into one inside local IP address.
