  Enable vty, console, AUX passwords are configured on the Cisco device. Use the show run command to show most passwords in clear text. If the service password-encryption is used, all the passwords are encrypted. As a result, the security of device access is improved.

• Question 842:

  A network administrator enters the following command on a router: logging trap 3. What are three message types that will be sent to the Syslog server? (Choose three.)

  A. informational
  B. emergency
  C. warning
  D. critical
  E. debug
  F. error

  The Message Logging is divided into 8 levels as listed below:

  Level Keyword Description emergencies System is unusable alerts Immediate action is needed critical Critical conditions exist errors Error conditions exist warnings Warning conditions exist notification Normal, but significant, conditions exist informational Informational messages debugging Debugging messages

  If you specify a level with the "logging trap level" command, that level and all the higher levels will be logged. For example, by using the "logging trap 3 command, all the logging of emergencies, alerts, critical, and errors, will be logged.

  Click the console connected to RouterC and issue the appropriate commands to answer the questions.

  

  What would be the effect of issuing the command ip access-group 115 in on the s0/0/1 interface?

  A. No host could connect to RouterC through s0/0/1.
  B. Telnet and ping would work but routing updates would fail.
  C. FTP, FTP-DATA, echo, and www would work but telnet would fail.
  D. Only traffic from the 10.4.4.0 network would pass through the interface.
  A. No host could connect to RouterC through s0/0/1.

  First let's see what was configured on interface S0/0/1:

  

• Question 846:

  which three technical services support cloud computing ?

  A. network-monitored power sources
  B. layer 3 network routing
  C. ip localization
  D. redundant connections
  E. VPN connectivity
  F. extended SAN services
  D. redundant connections
  E. VPN connectivity
  F. extended SAN services

• Question 847:

  Which header field is new on IPv6?

  A. Version
  B. Hop Limit
  C. Flow Label
  D. Traffic Class
  C. Flow Label

• Question 848:

  Refer to the exhibit.

  

  Host A pings interface S0/0 on router 3. What is the TTL value for that ping?

  A. 252
  B. 253
  C. 254
  D. 255
  B. 253

  ---

  From the CCNA ICND2 Exam book: "Routers decrement the TTL by 1 every time they forward a packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets from rotating forever." I want to make it clear that before the router forwards a packet, the TTL is still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2 have the same TTL. The picture below shows TTL values for each interface of each router and for Host B. Notice that Host A initializes ICMP packet with a TTL of 255:

  

• Question 849:

  At which severity level can syslog logging begin to affect router performance?

  A. debugging
  B. emergency
  C. notification
  D. critical
  D. critical

• Question 850:

  What is one requirement for interfaces to run IPv6?

  A. An IPv6 address must be configured on the interface.
  B. An IPv4 address must be configured.
  C. Stateless autoconfiguration must be enabled after enabling IPv6 on the interface.
  D. IPv6 must be enabled with the ipv6 enable command in global configuration mode.
  A. An IPv6 address must be configured on the interface.

  Explanation: To use IPv6 on your router, you must, at a minimum, enable the protocol and assign IPv6 addresses to your interfaces.
