• Question 961:

  An engineer must configure a multicast UDP jitter operation. Which configuration should be applied?

  A. Router(config)#ip sla 1Router(config)#udp-jitter 192.0.2.115 65051
  B. Router(config)#ip sla 1Router(config)#udp jitter 239.1.1.1 65051 end-point list List source-ip 192.168.1.1
  C. Router(config)#ip sla 1Router(config)#udp-jitter 192.0.2.115 65051 num-packets 20
  D. Router(config)#ip sla 1Router(config)#udp jitter 10.0.0.1 source-ip 192.168.1.1
  B. Router(config)#ip sla 1Router(config)#udp jitter 239.1.1.1 65051 end-point list List source-ip 192.168.1.1

  Explanation

  Basically you could argue that A, B and D are correct answers but only with regards to UDP Jitter IP SLA configuration. This question refers to multicast network meaning only B is correct as it identifes a multicast responder in the command line https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipsla/configuration/15-s/sla-15-s-book/sla_mcast_suppt.pdf

• Question 962:

  Refer to the exhibit.

  

  Which action completes the configuration to achieve a dynamic continuous mapped NAT for all users?

  A. Configure a match-host type NAT pool
  B. Reconfigure the pool to use the 192.168 1 0 address range
  C. Increase the NAT pool size to support 254 usable addresses
  D. Configure a one-to-one type NAT pool
  C. Increase the NAT pool size to support 254 usable addresses

  ---

  Explanation

  Why would you want to chose match-host option? This is just to ensure that you're matching the host portion of the IP range given of the Inside local to the inside global, which is not very applicable here.

  Go for C, this is much more applicable, if we assume we need to use the whole IP range of /24 and not just 1-100.

• Question 963:

  Which feature must be configured to allow packet capture over Layer 3 infrastructure'?

  A. VSPAN
  B. IPSPAN
  C. RSPAN
  D. ERSPAN
  D. ERSPAN

  ---

  Explanation

  Encapsulated remote SPAN (ERSPAN): encapsulated Remote SPAN (ERSPAN), as the name says, brings generic routing encapsulation (GRE) for all captured traffic and allows it to be extended across Layer 3 domains.

• Question 964:

  What does Call Admission Control require the client to send in order to reserve the bandwidth?

  A. SIP flow information
  B. Wi-Fi multimedia
  C. traffic specification
  D. VoIP media session awareness
  C. traffic specification

• Question 965:

  What is a characteristic of MACsec?

  A. 802.1AE is built between the host and switch using the MKA protocol, which negotiates encryption keys based on the primary session key from a successful 802.1X session.
  B. 802.1AE is negotiated using Cisco AnyConnect NAM and the SAP protocol.
  C. 802.1AE is built between the host and switch using the MKA protocol using keys generated via the Diffie-Hellman algorithm (anonymous encryption mode).
  D. 802.1AE provides encryption and authentication services.
  A. 802.1AE is built between the host and switch using the MKA protocol, which negotiates encryption keys based on the primary session key from a successful 802.1X session.

• Question 966:

  The following system log message is presented after a network administrator configures a GRE tunnel:

  %TUN-RECURDOWN Interface Tunnel 0 temporarily disabled due to recursive routing.

  Why is Tunnel 0 disabled?

  A. Because dynamic routing is not enabled
  B. Because the tunnel cannot reach its tunnel destination
  C. Because the best path to the tunnel destination is through the tunnel itself
  D. Because the router cannot recursively identify its egress forwarding interface.
  C. Because the best path to the tunnel destination is through the tunnel itself

  ---

  Explanation

  The %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing error message means that the generic routing encapsulation (GRE) tunnel router has discovered a recursive routing problem. This condition is usually due to one of these causes:

  + A misconfiguration that causes the router to try to route to the tunnel destination address using the tunnel interface itself (recursive routing) + A temporary instability caused by route flapping elsewhere in the network Reference: https:// www.cisco.com/c/en/us/support/docs/ip/enhan

• Question 968:

  Refer to the exhibit.

  

  An engineer must ensure that all traffic leaving AS 200 will choose Link 2 as the exit point. Assuming that all BGP neighbor relationships have been formed and that the attributes have not been changed on any of the routers.

  Which configuration accomplish task?

  A. R4(config-router)bgp default local-preference 200
  B. R3(config-router)neighbor 10.1.1.1 weight 200
  C. R3(config-router)bgp default local-preference 200
  D. R4(config-router)nighbor 10.2.2.2 weight 200
  A. R4(config-router)bgp default local-preference 200

  ---

  Explanation

  Local preference is an indication to the AS about which path has preference to exit the AS in order to reach a certain network. A path with a higher local preference is preferred. The default value for local preference is 100.

  Unlike the weight attribute, which is only relevant to the local router, local preference is an attribute that routers exchange in the same AS. The local preference is set with the "bgp default local-preference value " command.

  In this case, both R3 and R4 have exit links but R4 has higher local-preference so R4 will be chosen as the preferred exit point from AS 200.

• Question 969:

  Which function does a virtual switch provide?

  A. CPU context switching (or multitasking between virtual machines
  B. RAID storage for virtual machines
  C. emulation of power for virtual machines.
  D. connectivity between virtual machines
  D. connectivity between virtual machines

• Question 970:

  Refer to the exhibit.

  

  An engineer must reduce the number of Type 1 and Type 2 LSAs that are advertised to R4 within OSPF area 0. Which configuration must be applied?

  A. R1# conf tRouter(config)# router ospf 1Router(config-router)# prefix-suppression
  B. R4# conf tRouter(config)# router ospf 1Router(config-router)# summary-address 10.0.0.0 255.255.255.0
  C. R2# conf tRouter(config)# interface Gig0/0Router(config-router)# ip ospf prefix-suppression
  D. R2# conf tRouter(config)# int Gig0/0Router(config-if)# ip summary-address 10.0.0.0 255.255.255.0
  A. R1# conf tRouter(config)# router ospf 1Router(config-router)# prefix-suppression
