Refer to the exhibit.
R1 cannot establish a neighbor relationship with R2. Which action resolves the issue?
Answer: A
A. would fix this, even if it is bad practice B. would not fix MTU mismatch C. looks like it's already configured? D. would not fix anything

Refer to the exhibit.
R2 can reach Loopback222, but R1, SW1, and PC1 cannot communicate with 172.16.222.254. R1 and R2 configurations are shown here:
Which EIGRP configuration command resolves the issue?
Answer: B
A. we don't need to redistribute on this router, it already doesn't have the route needed B. we DO need to redistribute 172.16.222.0 0.0.0.255 in eigrp for it to work C. without doing this on the eigrp instance it wouldnt be valid - this is my understanding from it being labeled (config-router) D. same as C

Tasks - A network is configured with CoPP to protect the CORE router route processor for stability and DDoS protection. As a company policy, a class named class-default is preconfigured and must not be modified or deleted. Troubleshoot CoPP to resolve the issues introduced during the maintenance window to ensure that: 1. Dynamic routing policies are under CoPP-CRITICAL and are allowed only from the 10.10.x.x range. 2. Telnet, SSH, and ping are under CoPP-IMPORTANT and are allowed strictly to/from 10.10.x.x to the CORE router (Hint: you can verify using Loopback1). 3. All devices ping (UDP) any CORE router interface successfully to/from the 10.10.x.x range and do not allow any other IP address. 4. All devices run a successful traceroute (UDP) to any interface on the CORE router to/from the 10.10.x.x range, are under CoPP-NORMAL, and do not allow any other IP address traceroute is to be under CoPP-NORMAL (Hint: Traceroute port range 33434 33464).
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
The statement implies that you do not need to configure the policy, class-map or apply it to the control plane. Does anyone agree with me?

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: 1. 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. 2. 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. 3. 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. 4. R6 advertises its Loopback1 /24 address through BGP.

Answer: See figure below
Labbed as best I could without seeing the actual configs. Part 1 Router 4+5 Add static route to 10.20.0.0 255.255.0.0 null0 Advertise to BGP with network statement Part 2 Router 4 and 5. Match relevant R2 loopback using a standard access list. Create route map (question implies modification of existing). Permit 10 match access list and set LP to 100+routerID. Permit 20 match all/permit all (blank). Part3 Advertise Loopback on R6 using network statement.

How does BFD protocol work?
Answer: C
Refer to the exhibit. An engineer implements uRPF to increase security and stop incoming spoofed IP packets. Same asymmetrically routed packets are also blocked after the configuration. Which command resolves the issue?
Answer: A
C: ip verify unicast reverse-path is the command for older IOS versions, and only supports strict mode D: This command does no exist. reverse-path does not support loose mode. B: This is what is currently configured. A: We want to allow asymmetrically return traffic by using loose mode.

Refer to the exhibit. After an engineer modified the configuration for area 7 to permit type 1, 2, and 7 LSAs only, users connected to router R9 reported that they could no longer access the internet. Which configuration restores internet access to users on R9 and permits only LSA type 1, 2, and 7?
Answer: B
Option C configures area 7 as a NSSA without the no-summary option on R4. This allows the injection of type 7 LSAs into the area, but also allows the propagation of inter-area summary LSAs into the area. However, this option does not generate a default summary route for area 7, which means R9 has no route to reach the internet4. Option D configures area 7 as a NSSA with the default-information originate option on R4. This allows the injection of type 7 LSAs into the area, but also allows the propagation of inter-area summary LSAs into the area. The default-information originate option generates a type 7 default route for area 7, which can be used by R9 to reach the internet. However, this option is redundant and less efficient than Option B, because it injects both a type 3 and a type 7 LSA for the default route into the area5.

An engineer configured access list NON-CISCO in a policy to influence routes.
What are the two effects of this route map configuration? (Choose two.)
Answer: AD
Seq 5 has a match ACL ---Deny Seq 10 has no match so Match Everything ---Permit So a packet ether it matched by ACL and forwarded using normal route lookup or does not get matched by ACL and evaluated by sequence 10. A , D

Refer to the exhibit. An engineer recently implemented uRPF by configuring the ip verify unicast source reachable-via rx command on interface gi0/3. The engineer noticed right after implementing uRPF that an inbound packet on the gi0/3 interface with a source address of 172.16.3.251 was dropped. Which action resolves the issue?
Answer: A
Which IPv6 feature enables a device to reject traffic when it is originated from an address that is not stored in the device binding table?
