  A. Both routers are designated routers.
  B. different area ID
  C. mismatched OSPF network types
  D. authentication error
  E. area type mismatch
  E. area type mismatch

• Question 603:

  Refer to the exhibit.

  

  Which IP packets will be accepted from EBGP neighbor 10.1.1.1?

  A. IP packets with a TTL count in the header that is equal to or greater than 253
  B. IP packets with a TTL count in the header that is equal to 253
  C. IP packets with a TTL count in the header that is equal to or greater than 2
  D. IP packets with a TTL count in the header that is equal to 2
  A. IP packets with a TTL count in the header that is equal to or greater than 253

  neighbor ip-address ttl-security hops hop-count

  ExamplE.

  Router(config-router)# neighbor 10.1.1.1 ttl-security hops 2 Configures the maximum number of hops that separate two peers.

  The hop-count argument is set to number of hops that separate the local and remote peer. If the expected TTL value in the IP packet header is 254, then the number 1 should be

  When this feature is enabled, BGP will accept incoming IP packets with a TTL value that is

  equal to or greater than the expected TTL value. Packets that are not accepted are silently discarded.

  The example configuration sets the expected incoming TTL value to at least 253, which is 255 minus the TTL value of 2, and this is the minimum TTL value expected from the BGP peer. The local router will accept the peering session from

  the 10.1.1.1 neighbor only if it is 1 or 2 hops away.

• Question 604:

  Which option is the default number of routes over which EIGRP can load balance?

  A. 1
  B. 4
  C. 8
  D. 16
  B. 4

  ---

  By default, EIGRP load-shares over four equal-cost paths. For load sharing to happen, the routes to load-share over must show up in the IP forwarding table or with the show ip route command. Only when a route shows up in the forwarding table with multiple paths to it will load sharing occur.

• Question 605:

  How is the MRU for a multilink bundle determined?

  A. It is negotiated by LCP.
  B. It is manually configured on the multilink bundle.
  C. It is manually configured on all physical interfaces of a multilink bundle.
  D. It is negotiated by NCP.
  E. It is negotiated by IPCP.
  A. It is negotiated by LCP.

• Question 606:

  Which three TLVs does LLDP use to discover network devices? (Choose three.)

  A. Management address
  B. Port description
  C. Network policy
  D. System name
  E. Location information
  F. Power management
  A. Management address
  B. Port description
  D. System name

  ---

  Basic Management TLV Set

  This set includes the following five TLVs used in LLDP:

  Port description TLV: Provides a description of the port in an alpha-numeric format. The value equals the ifDescr object, if the LAN device supports RFC 2863. System name TLV: Provides the system's assigned name in an alpha-numeric

  format. The value equals the sysName object, if the LAN device supports RFC 3418.

  System description TLV: Provides a description of the network entity in an alpha- numeric format. This includes system's name and versions of hardware, operating system and networking software supported in the device. The value equals

  the sysDescr object, if the LAN device supports RFC 3418. System capabilities TLV: Indicates the primary function(s) of the device and whether or not these functions are enabled in the device. The capabilities are indicated by two octects.

  Bits 0 through 7 indicate Other, Repeater, Bridge, WLAN AP, Router, Telephone, DOCSIS cable device and Station respectively. Bits 8 through 15 are reserved.

  Management address TLV: Indicates the addresses of the local LLDP agent. Other remote managers can use this address to obtain information related to the local device.

• Question 607:

  Which two statements about the max-age time in IS-IS are true? (Choose two.)

  A. The IS-IS max-age time is 20 minutes by default.
  B. The IS-IS max-age time is 60 minutes by default.
  C. The IS-IS max-age time increments from zero to max-age.
  D. The IS-IS max-age time decrements from max-age to zero.
  A. The IS-IS max-age time is 20 minutes by default.
  D. The IS-IS max-age time decrements from max-age to zero.

• Question 608:

  DRAG DROP

  Drag and drop each MLPPP command on the left to the function it performs on the right.

  Select and Place:

  

  

• Question 609:

  Which statement is true about trunking?

  A. Cisco switches that run PVST+ do not transmit BPDUs on nonnative VLANs when using a dot1q trunk.
  B. When removing VLAN 1 from a trunk, management traffic such as CDP is no longer passed in that VLAN.
  C. DTP only supports autonegotiation on 802.1q and does not support autonegotiation for ISL.
  D. DTP is a point-to-point protocol.
  D. DTP is a point-to-point protocol.

  ---

  Ethernet trunk interfaces support different trunking modes. You can set an interface as trunking or nontrunking or to negotiate trunking with the neighboring interface. To autonegotiate trunking, the interfaces must be in the same VTP domain.

  Trunk negotiation is managed by the Dynamic Trunking Protocol (DTP), which is a Point-to- Point Protocol. However, some internetworking devices might forward DTP frames improperly, which could cause misconfigurations.

• Question 610:

  Which service is disabled by the no service tcp-small-servers command?

  A. the finger service
  B. the Telnet service
  C. the Maintenance Operation Protocol service
  D. the chargen service
  D. the chargen service

  ---

  The TCP small servers are:

  Echo: Echoes back whatever you type through the telnet x.x.x.x echo command. Chargen: Generates a stream of ASCII data. Use the telnet x.x.x.x chargen command.

  DiscarD. Throws away whatever you type. Use the telnet x.x.x.x discard command.

  DaytimE. Returns system date and time, if it is correct. It is correct if you run Network Time Protocol (NTP), or have set the date and time manually from the exec level. Use the telnet x.x.x.x daytime command.
