(Choose two.) A.    In Short Pipe mode QoS is done on the PE-to-CE link based on the customer's PHB markingsB.    In Pipe mode QoS is done on the PE-to-CE link based on the service provider's PHB markingsC.    In Pipe mode QoS is done on the PE-to-CE link based on the customer's PHB markingsD.    In Short Pipe mode QoS is done on the PE-to-CE link based on the service provider's PHB markingsE.    Short Pipe mode does not need MPLS usage, but Pipe mode does Answer: AB QUESTION 152Refer to the exhibit. What is the available reservable bandwidth for P6 after successful establishment of Tunnel 1? A.    490 KbpsB.    500 KbpsC.    490 MbpsD.    500 Mbps Answer: D QUESTION 153How is bandwidth recalculated when utilizing the automatic bandwidth adjustment feature for MPLS TE? A.    The tunnel's output average is periodically sampled and then the bandwidth is adjusted to the largest sample obtained during the period, or to the configured maximumB.    The tunnel's output is sampled and then the bandwidth is adjusted by a configured percentage until the configured maximum value is reachedC.    Ping is used to measure congestion and the bandwidth is adjusted by a configured percentage until the maximum value is reachedD.    Ping is used to measure congestion and the bandwidth is adjusted to either the minimum, average, or maximum configured bandwidth value Answer: A QUESTION 154Which two advantages are reasons that service providers might deploy MPLS? (Choose two.) A.    to avoid using IGP in the coreB.    to facilitate smooth migrations between legacy WAN technologiesC.    to reduce the throughput overhead of full IPv4/IPv6 headers when traversing the coreD.    to reduce the computational requirements that are placed on router CPUsE.    to reduce configuration and feature requirements in the core Answer: CD QUESTION 155In Cisco IOS, what must be configured to ensure that an MPLS TE tunnel becomes active? A.    layer 3 addressing on the tunnel, to establish bidirectional communication over the tunnelB.    the tunnel for autoroute, to ensure proper installation into the forwarding planeC.    a path-option configuration, for either dynamic or explicit pathsD.    the tunnel with a minimum bandwidth value, to properly calculate CSPF Answer: A QUESTION 156Which option shows how a class map is implemented that matches only packets originating from the network 10.0.0.0/8, which are not marked as VoIP on Cisco IOS XE? A.    B.     C.     D.     Answer: B QUESTION 157An engineer is having a problem getting an operational 10 Gigabit link on a Cisco ASR 9000 series router. The service provider instructs the engineer to use an LR optic. The engineer must access the router remotely.Which command should the engineer issue to determine that the correct optic has been installed? A.    show controllersB.    show module opticsC.    show ip interfaceD.    show optics Answer: A QUESTION 158Which message is sent through the desired LSP path by the headend router and is used to determine available resources? A.    PATHB.    TENTC.    RSVPD.    RESV Answer: A QUESTION 159An engineer sets up QoS over MPLS networks. How many classes of traffic can one LSP support? A.    as many as 8, because the EXP field is 3 bitsB.    as many as 3, because the EXP field is 3 bitsC.    as many as 64, because the DSCP field is 6 bitsD.    as many as 6, because the DSCP field is 6 bits Answer: A QUESTION 160An engineer deployed a Cisco MPLS TE next-hop protection over a switched environment. While testing the link protection, an excessive IGP delay in the reconvergence time is seen.Which action fixes this issue? A.    Replace the existing link with a routed back-to back linkB.    Configure object trackingC.    Set up more aggressive IGP timersD.    Implements BFD on the link Answer: B 642-887 dumps full version (PDF&VCE): https://www.lead2pass.com/642-887.html Large amount of free 642-887 exam questions on Google Drive: https://drive.google.com/open?id=0B3Syig5i8gpDbDZBdmJlTVVwMWc You may also need: 642-883 exam dumps: https://drive.google.com/open?id=0B3Syig5i8gpDVURjdjBlUFh1TG8 642-885 exam dumps: https://drive.google.com/open?id=0B3Syig5i8gpDYThUdmRiZl9vWWM 642-889 exam dumps: https://drive.google.com/open?id=0B3Syig5i8gpDV2E5dFE0emtPekE --------------------------------------------------- Images: http://examgod.com/l2pimage/3f0db3e49dcc_A2CD/1521_thumb.jpg http://examgod.com/l2pimage/3f0db3e49dcc_A2CD/1561_thumb.jpg http://examgod.com/l2pimage/3f0db3e49dcc_A2CD/1562_thumb.jpg http://examgod.com/l2pimage/3f0db3e49dcc_A2CD/1563_thumb.jpg http://examgod.com/l2pimage/3f0db3e49dcc_A2CD/1564_thumb.jpg --------------------------------------------------- --------------------------------------------------- Post date: 2018-03-31 03:49:54 Post date GMT: 2018-03-31 03:49:54 Post modified date: 2018-03-31 03:49:54 Post modified date GMT: 2018-03-31 03:49:54 ____________________________________________________________________________________________ Export of Post and Page as text file has been powered by [ Universal Post Manager ] plugin from www.gconverters.com
