  Topology

  

  Tasks

  Configure HUB and SPOKE routers according to the topology to achieve these goals:

  1. Configure mGRE neighborship by using physical interface IP addresses to provide end-to-end reachability. Verify all router’s tunnel interfaces accordingly.

  2. Configure NHRP on HUB router as multipoint dynamic IP to NBMA mapping. SPOKE1 and SPOKE2 routers should be configured by using static NHS and multicast mapping for HUB. Use network-id 10 for NHRP. Verify NHRP neighborship between routers and verify results using ping from PC1 to PC2 and PC3 accordingly.

• Question 553:

  Refer to the exhibit.

  

  The network administrator must mutually redistribute routes at the Chicago router to the LA and NewYork routers. The configuration of the Chicago router is this:

  

  After the configuration, the LA router receives all the NewYork routes, but NewYork router does not receive any LA routes. Which set of configurations fixes the problem on the Chicago router?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  "LA router receives all the NewYork routes but it does not receive any LA routes" because when redistrubuting into EIGRP, we must configure the default metric.

• Question 554:

  A. Configure DSW1(dhcp-config)#default-router 2002:A04:A01::A04:A01
  B. Configure DSW1(config-if)#ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet1/2

  D. Configure DSW1(config-if)#ipv6 helper address 2002:404:404::404:404
  B. Configure DSW1(config-if)#ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet1/2

• Question 555:

  Which tag is used by the PE router to forward the packet to the correct customer?

  A. RD
  B. extended-community
  C. RT
  D. VNI
  A. RD

• Question 556:

  You are implementing IP SLA and would like to use it to measure hop-by-hop response time between a Cisco router and any IP device on the network.

  Which of the following IP SLA operations would you use for this?

  A. ICMP path echo operation
  B. Internet Control Message Protocol Echo Operation
  C. UDP Jitter Operation for VoIP
  D. UDP Jitter Operation
  A. ICMP path echo operation

  ---

  The ICMP path echo operation discovers the path using the traceroute command, and then measures response time between the source router and each intermittent hop in the path. IP SLAs allow users to monitor network performance between Cisco routers or from either a Cisco router to a remote IP device.

  The Internet Control Message Protocol (ICMP) Echo Operation measures end-to-end response time between a Cisco router and any IP-enabled device. Response time is computed by measuring the time taken between sending an ICMP echo request message to the destination and receiving an ICMP echo reply. It does not measure hop-by-hop response time.

  The UDP Jitter Operation for VoIP is an extension to the current jitter operations with specific enhancements for VoIP. The enhancements allow this operation to calculate voice quality scores and simulate the codec's directly in CLI and the MIB. It does not measure hop-by-hop response time.

  The UDP Jitter Operation is designed to measure the delay, delay variance, and packet loss in IP networks by generating active UDP traffic. It does not measure hop-by-hop response time.

  Objective:

  Infrastructure Services

  Sub-Objective:

  Describe SLA architecture

• Question 557:

  Refer to the exhibit.

  

  A junior engineer updated a branch router configuration. Immediately after the change, the engineer receives calls from the help desk that branch personnel cannot reach any network destinations.

  Which configuration restores service and continues to block 10.1.1.100/32?

  A. route-map FILTER-IN deny 5
  B. ip prefix-list 102 seq 15 permit 0.0.0.0/32 le 32
  C. ip prefix-list 102 seq 5 permit 0.0.0.0/32 le 32
  D. route-map FILTER-IN permit 20
  D. route-map FILTER-IN permit 20

  ---

  By using "deny" keyword in a route-map, we can filter out the prefix specified in the prefix-list.

  But there is an implicit "deny all" statement in the prefix-list so we must permit other prefixes with "permit" keyword in the route-map.

• Question 558:

  Refer to the exhibit. A network administrator notices these console messages from host 10.11.110.12 originating from interface E1/0. The administrator considers this an unauthorized attempt to access SNMP on R1. Which action prevents the attempts to reach R1 E1/0?

  

  A. Configure IOS management plane protection using ACL 90 on interface E1/0.
  B. Configure IOS control plane protection using ACL 90 on interface E1/0.
  C. Add a permit statement including the host 10.11.110.12 into ACL 90.
  D. Create an inbound ACL on interface E1/0 to deny SNMP from host 10.11.110.12.
  D. Create an inbound ACL on interface E1/0 to deny SNMP from host 10.11.110.12.

• Question 559:

  Refer to the exhibit.

  

  An engineer notices a connectivity problem between routers R1 and R2. The frequency of this problem is high during peak business hours. Which action resolves the issue?

  A. Increase the available bandwidth between R1 and R2.
  B. Decrease the EIGRP keepalive and hold down timers on R1 and R2.
  C. Increase the MTU on the interfaces that connect R1 and R2.
  D. Set static EIGRP neighborship between R1 and R2.
  A. Increase the available bandwidth between R1 and R2.

  ---

  EIGRP DUAL-3-SIA

  1. Missing or incorrect bandwidth interface configuration parameter

  2. Incorrect bandwidth configured to influence path selection https://www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/13676-18.html

• Question 560:

  Refer to the exhibit.

  

  Router R1 peers with two ISPs using static routes to get to the internet. The requirement is that R1 must prefer ISP-A under normal circumstances and failover to ISP-B if the connectivity to ISP-A is lost. The engineer observes that R1 is load balancing traffic across the two ISPs Which action resolves the issue by sending traffic to ISP-A only with failover to ISP-B?

  A. Configure OSPF between R1, ISP-A, and ISP-B for dynamic failover if any ISP link to R1 fails.
  B. Configure two static routes on R1, one pointing to ISP-A and another pointing to ISP- B with 222 admin distance.
  C. Change the bandwidth of the interface on R1 so that interface to ISP-A has a higher value than the interface to ISP-B.
  D. Configure two static routes on R1, one pointing to ISP-B with more specific routes and another pointing to ISP-A with summary routes.
  B. Configure two static routes on R1, one pointing to ISP-A and another pointing to ISP- B with 222 admin distance.
