Cisco 640-802 Online Questions & Answers

• Question 121:

  Which IPv6 address is the equivalent of the IPv4 interface loopback address 127.0.0.1?

  A. ::1
  B. ::
  C. 2000::/3
  D. 0::/10
  A. ::1

  ---

  In IPv6 the loopback address is written as, ::1

  This is a 128bit number, with the first 127 bits being '0' and the 128th bit being '1'. It's just a single address, so could also be written as ::1/128.

• Question 122:

  What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

  A. 2
  B. 8
  C. 16
  D. unlimited
  B. 8

  ---

  maximum-paths (OSPF)

  To control the maximum number of parallel routes that Open Shortest Path First (OSPF) can support, use the maximum-paths command.

  Syntax Description

  

  Command Default 8 paths

• Question 123:

  What command instructs the device to timestamp Syslog debug messages in milliseconds?

  A. service timestamps log datetime localtime
  B. service timestamps debug datetime msec
  C. service timestamps debug datetime localtime
  D. service timestamps log datetime msec
  B. service timestamps debug datetime msec

  ---

  Enable millisecond (msec) timestamps using the service timestamps command:

  router(config)#service timestamps debug datetime msec.

  router(config)#service timestamps log datetime msec The "service timestamps debug".

  command configures the system to apply a time stamp to debugging messages. The time-stamp format for datetime is MMM DD HH:MM:SS, where MMM is the month, DD is the date, HH is the hour (in 24-hour notation), MM is the minute,

  and SS is the second. With the additional keyword msec, the system includes milliseconds in the time stamp, in the format HH:DD:MM:SS.mmm, where .mmm is milliseconds.

• Question 124:

  Which three statements about HSRP operation are true? (Choose three.)

  A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.
  B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
  C. HSRP supports only clear-text authentication.
  D. The HSRP virtual IP address must be on a different subnet than the routers' interfaces on the same LAN.
  E. The HSRP virtual IP address must be the same as one of the router's interface addresses on the LAN.
  F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.
  A. The virtual IP address and virtual MA+K44C address are active on the HSRP Master router.
  B. The HSRP default timers are a 3 second hello interval and a 10 second dead interval.
  F. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.

  The virtual MAC address of HSRP version 1 is 0000.0C07.ACxx, where xx is the HSRP group number in hexadecimal based on the respective interface. For example, HSRP group 10 uses the HSRP virtual MAC address of 0000.0C07.AC0A. HSRP version 2 uses a virtual MAC address of 0000.0C9F.FXXX (XXX: HSRP group in hexadecimal).

• Question 125:

  Refer to the exhibit.

  

  All switch ports are assigned to the correct VLANs, but none of the hosts connected to SwitchA can communicate with hosts in the same VLAN connected to SwitchB. Based on the output shown, what is the most likely problem?

  A. The access link needs to be configured in multiple VLANs.
  B. The link between the switches is configured in the wrong VLAN.
  C. The link between the switches needs to be configured as a trunk.
  D. VTP is not configured to carry VLAN information between the switches.
  E. Switch IP addresses must be configured in order for traffic to be forwarded between the switches.
  C. The link between the switches needs to be configured as a trunk.

  ---

  In order to pass traffic from VLANs on different switches, the connections between the switches must be configured as trunk ports.

• Question 126:

  Which IPv6 header field is equivalent to the TTL?

  A. Hop Limit
  B. Flow Label
  C. TTD
  D. Hop Count
  E. Scan Timer
  A. Hop Limit

• Question 127:

  Refer to the exhibit.

  

  The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three.)

  A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports.
  B. Ensure that cables A and B are straight-through cables.
  C. Ensure cable A is plugged into a trunk port.
  D. Ensure the switch has power.
  E. Reboot all of the devices.
  F. Reseat all cables.
  B. Ensure that cables A and B are straight-through cables.
  D. Ensure the switch has power.
  F. Reseat all cables.

  ---

  The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.

• Question 128:

  Refer to the exhibit.

  

  The network administrator must establish a route by which London workstations can forward traffic to the Manchester workstations. What is the simplest way to accomplish this?

  A. Configure a dynamic routing protocol on London to advertise all routes to Manchester.
  B. Configure a dynamic routing protocol on London to advertise summarized routes to Manchester.
  C. Configure a dynamic routing protocol on Manchester to advertise a default route to the London router.
  D. Configure a static default route on London with a next hop of 10.1.1.1.
  E. Configure a static route on London to direct all traffic destined for 172.16.0.0/22 to 10.1.1.2.
  F. Configure Manchester to advertise a static default route to London.
  E. Configure a static route on London to direct all traffic destined for 172.16.0.0/22 to 10.1.1.2.

  ---

  This static route will allow for communication to the Manchester workstations and it is better to use this more specific route than a default route as traffic destined to the Internet will then not go out the London Internet connection.

• Question 129:

  SIMULATION

  CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP.

  CCNA.com has recently added the ENG router. Currently, the ENG router does not have connectivity to the ISP router. All over interconnectivity and Internet access for the existing locations of the company are working properly.

  The task is to identify the fault(s) and correct the router configuration(s) to provide full connectivity between the routers.

  Access to the router CLI can be gained by clicking on the appropriate host.

  All passwords on all routers are cisco.

  IP addresses are listed in the chart below.

• Question 130:

  Refer to the exhibit.

  

  Assuming that the entire network topology is shown, what is the operational status of the interfaces of R2 as indicated by the command output shown?

  A. One interface has a problem.
  B. Two interfaces have problems.
  C. The interfaces are functioning correctly.
  D. The operational status of the interfaces cannot be determined from the output shown.
  C. The interfaces are functioning correctly.

  ---

  The output shown shows normal operational status of the router's interfaces. Serial0/0 is down because it has been disabled using the "shutdown" command.
