• Question 301:

  Select and Place:

  

  

• Question 302:

  A network engineers is configuring L2VPN static point-to-point cross connect on the CRS router. Drag the configuration steps on the left in the correct order on the right.

  Select and Place:

  

  

• Question 303:

  What are the default values for GRE tunnel keepalive time and number of retries?

  A. 5 seconds and 3 retries
  B. 10 seconds and 5 retries
  C. 10 seconds and 3 retries
  D. 20 seconds and 5 retries
  E. 5 seconds and 5 retries
  C. 10 seconds and 3 retries

  ---

  This output shows the commands you use in order to configure keepalives on GRE tunnels. Router# configure terminal Router(config)#interface tunnel0 Router(config-if)#keepalive 5 4 !--- The syntax of this command is keepalive [seconds [retries]]. !--- Keepalives are sent every 5 seconds and 4 retries. !--- Keepalives must be missed before the tunnel is shut down. !--- The default values are 10 seconds for the interval and 3 retries.

• Question 304:

  Which two models are the models of DiffServ-Aware Traffic Engineering? (Choose two)

  A. Policy-based Model
  B. Class based Model
  C. Russian Doll Model
  D. Global Tunnel Model
  E. Maximum Allocation Model
  C. Russian Doll Model
  E. Maximum Allocation Model

  ---

  Therefore in practice, a Network Administrator might prefer to use:

  穞he Maximum Allocation Model when s/he needs to ensure isolation across all Class Types without having to use pre-emption, and s/he can afford to risk some QoS degradation of Class Types other than the Premium Class.

  穞he Russian Dolls Model when s/he needs to prevent QoS degradation of all Class Types and can impose preemption.

• Question 305:

  A security agency wants to use the services of the service provider to interconnect the remote sites. However, they do not want to share the IP addresses of their sites and they want end-to-end security.

  Which three services meet the design requirements? (Choose three.)

  A. client mode VPN
  B. tunnel mode VPN
  C. L2VPN
  D. L3VPN
  E. PPTP
  F. SSL VPN
  A. client mode VPN
  B. tunnel mode VPN
  C. L2VPN

• Question 306:

  Which statement is FALSE concerning Concatenation?

  A. It allows ITCM to send multiple upstream packets in one single large burst.
  B. It reduces upstream data throughput.
  C. It can be enabled/disabled from CMTS on per upstream port basis if desired
  D. Concatenation activity on an interface can be checked by the show controller counters command
  B. It reduces upstream data throughput.

• Question 307:

  What is true regarding Autonomous Systems (AS)?

  A. All of the Above
  B. AS numbers are assigned by the IANA
  C. AS numbers are used by BGP (Border Gateway protocol to exchange IP routing information with neighboring AS
  D. In the internet, an Autonomous System (AS) is a collection of IP networks and routers under the control
  A. All of the Above

• Question 308:

  What three major tasks are performed by a Designated Intermediate System in an ISIS pseudonode environment? (Choose three.)

  A. updating the pseudonode LSP
  B. maintaining pseudonode link-state information
  C. creating the pseudonode LSP
  D. flooding LSPs over the LAN
  E. election of the pseudonode
  A. updating the pseudonode LSP
  C. creating the pseudonode LSP
  D. flooding LSPs over the LAN

  ---

  Two major tasks are performed by the DIS:

  ?Creating and updating pseudonode LSP for reporting links to all systems on the broadcast subnetwork. See the Pseudenode LSP section for more information.

  ?Flooding LSPs over the LAN.

  Flooding over the LAN means that the DIS sends periodic complete sequence number protocol data units (CSNPs) (default setting of 10 seconds) summarizing the following information:

  LSP ID

  Sequence Number

  Checksum

  Remaining Lifetime

  The DIS is responsible for flooding. It creates and floods a new pseudonode LSP for each routing level in which it is participating (Level 1 or Level 2) and for each LAN to which it is connected. A router can be the DIS for all connected LANs or

  a subset of connected LANs, depending on the IS-IS priority or the Layer 2 address.

  The DIS will also create and flood a new pseudonode LSP when a neighbor adjacency is established, torn down, or the refresh interval timer expires. The DIS mechanism reduces the amount of flooding on LANs.

• Question 309:

  What type of IPv6 address is this address FF05::2:260:8FF:FE52:F9D8?

  A. multicast temporary node local
  B. multicast temporary site local
  C. unicast permanent link local
  D. multicast permanent node link local
  E. multicast permanent site local
  F. unicast temporary link local
  E. multicast permanent site local

  ---

  Permanent IPv6 Multicast addresses are assigned by IANA while the temporary IPv6 Multicast addresses can be used in pre-deployment Multicast testing. The Flag field may contain one of two possible values, as illustrated and described in the Table below: Type of Multicast Address Binary Representation Hexadecimal Value Permanent 0000 0 Temporary 0001 1 Multicast scope The scope field indicates the scope of the IPv6 internetwork for which the multicast traffic is intended. The size of this field is 4 bits. In addition to information provided by multicast routing protocols, routers use multicast scope to determine whether multicast traffic can be forwarded. For multicast addresses there are 14 possible scopes (some are still unassigned), ranging from interface-local to global (including both link-local and sitelocal). The following table lists the defined values for the scope field: Table 3. Multicast scope field values Value Scope 0 Reserved 1 Interface-local scope (same node) 2 Link-local scope (same link) 3 Subnet-local scope 4 Admin-local scope 5 Site-local scope (same site) 8 Organization-local scope E Global scope F Reserved All other scope field values are currently undefined. For example, traffic with the multicast address of FF02::2 has a link-local scope. An IPv6 router never forwards this type of traffic beyond the local link.
