A network engineer troubleshooting a packet drop problem for the host 172.16.100.5 notices that only one link is used and installed on the routing table, which saturates the bandwidth. Which action must the engineer take to resolve the high bandwidth utilization problem and share the traffic toward this host between the two available links?
ADisable the eigrp split horizon loop protection mechanism.
BSet the eigrp variance equal to 3 to install a second route with a metric not larger than 3 times of the best metric.
CChange the EIGRP delay metric to meet the feasibility condition.
DSet the eigrp variance equal to 4 to install a second route with a metric not larger than 4 times of the best metric.

A
B
C

Refer to the exhibit.
An engineer observes that every time the ICMP packet is lost at a polling interval, track 1 goes down, which causes unnecessary disruption and instability in the network. The engineer does not want the traffic to be rerouted if the loss of ICMP packets is negligible. If the packet loss is persistent for a longer duration, the track must go down and the traffic must be rerouted. Which action resolves the issue?
AChange the IP SLA schedule to run only at certain intervals.
BIncrease the timeout value from 1000 to 1500.
CDefine a delay timer under track 1.
DIncrease the threshold value from 1000 to 1500.

Topology
Tasks
A company is connected to an ISP and some of the networks between the ISP and the company are not reachable. Troubleshoot and resolve the issues to achieve these goals:
A single /16 is advertised for all infrastructure-connected interfaces that belong to the 10.20.x.x network using BGP network commands from border routers connected to the ISP. Configuration modification is allowed in R4 and R5 to achieve the results. Do not use the BGP aggregate command.
R6 receives the ISP R2 Loopback2 from R4 and receives a summary address for both Loopbacks of ISP R2 from R4 or R5. Use BGP attribute local-preference, add , for example, for R6, use “default+6 = value to be used”. Use the existing prefix lists or route maps with the sequence numbering starting at 10 and added in increments of 10.
R6 receives the ISP R2 Loopback1 from R5 and receives a summary address for both Loopbacks of ISP R2 from R4 or R5 using the same guidelines.
R6 advertises its Loopback1 /24 address through BGP.
Refer to the exhibit. An administrator noticed that after a change was made on R1, the timestamps on the system logs did not match the clock.
What is the reason for this error?
AAn authentication error with the NTP server results in an incorrect timestamp.
BThe keyword localtime is not defined on the timestamp service command.
CThe NTP server is in a different time zone.
DThe system clock is set incorrectly to summer-time hours.
What is a prerequisite for configuring BFD?
AJumbo frame support must be configured on the router that is using BFD.
BAll routers in the path between two BFD endpoints must have BFD enabled.
CCisco Express Forwarding must be enabled on all participating BFD endpoints.
DTo use BFD with BGP, the timers 3 9 command must first be configured in the BGP routing process.
