NEW QUESTION # 184
Refer to the exhibit.
The branch router is configured with a default route toward the internet and has no routes configured for the HQ site that is connected through interface G2/0. The HQ router is fully configured and does not require changes. Which configuration on the branch router makes the intranet website (TCP port 80) available to the branch office users?
A)
B)
C)
D)
- A. Option B
- B. Option A
- C. Option C
- D. Option D
Answer: A
Explanation:
the ACL 101 matches all HTTP pakects while the ACL 102 matches TCP packets destined to Intranet webserver. These packets will be sent to HQ router.
If a match command refers to several objects in one command, either of them should match (the logical OR algorithm is applied). For example, in the match ip address 101 102 command, a route is permitted if it is permitted by access list 101 or access list 102.

Answer: A,D
NEW QUESTION # 187
Refer to the exhibit.
BGP and EIGRP are mutually redistributed on R3, and EIGRP and OSPF are mutually redistributed on R1.
Users report packet loss and interruption of service to applications hosted on the 10.1.1.0724 prefix. An engineer tested the link from R3 to R4 with no packet loss present but has noticed frequent routing changes on R3 when running the debug ip route command. Which action stabilizes the service?
- A. Tag the 10.1.1.0/24 prefix and deny the prefix from being redistributed into OSPF on R1.
- B. Place an OSPF distribute-list outbound on R3 to block the 10.1.10/24 prefix from being advertised back to R3.
- C. Repeat the test from R4 using ICMP ping on the local 10.1.1.0/24 prefix, and fix any Layer 2 errors on the host or switch side of the subnet.
- D. Reduce frequent OSPF SPF calculations on R3 that cause a high CPU and packet loss on traffic traversing R3.
Answer: A
Explanation:
Explanation
After redistribution, R3 learns about network 10.1.1.0/24 via two paths:
+ Internal BGP (IBGP): advertised from R4 with AD of 200 (and metric of 0)
+ OSPF: advertised from R1 with AD of 110 (O E2) (and metric of 20)
Therefore R3 will choose the path with the lower AD via OSPF
But this is a looped path which is received from R3 -> R2 -> R1 -> R3. So when the advertised route from R4 is expired, the looped path is also expired soon and R3 will reinstall the main path from R4.
This is the cause of intermittent connectivity.
We can solve this problem by denying the 10.1.1.0/24 prefix from being redistributed into OSPF on R1. So R3 will not learn this prefix from R1.
Or another solution is to place an OSPF distribute-list inbound on R3 to block the 10.1.1.0/24 prefix from being advertised back to R3.
NEW QUESTION # 188
Exhibit:
BGP is flapping after the Copp policy is applied. What are the two solutions to fix the issue?
(Choose two)
- A. Configure a three-color policer instead of two-color policer under class COPP-CRITICAL-
7600 - B. Configure a higher value for CIR under the default class to allow more packets during peak traffic
- C. Configure IP CEF to CoPP policy and BGP to work
- D. Configure BGP in the COPP-CRITICAL-7600 ACL
- E. Configure a higher value for CIR under the class COPP-CRITICAL-7600
Answer: B,D
Explanation:
Explanation
The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACL conditions) so any BGP packets will be processed in the class "class-default", which drops exceeded BGP packets. Therefore we have two ways to solve this problem:
+ Add BGP to the ACL with the statement "permit tcp any any eq bgp"
+ Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http &
https)

NEW QUESTION # 190
Refer to the exhibit.
An engineer is troubleshooting a TACACS problem.
Which action resolves the issue?
- A. Generate authentication from a relative source interface.
- B. Apply a configured AAA profile to the VTY.
- C. Configure a matching TACACS server IP.
- D. Configure a matching preshared key.
Answer: D
Explanation:
Reference:
https://community.cisco.com/t5/network-access-control/issues-with-tacacs-authentication/td-p/3412001 The last line shows us the reason, which is "Invalid AUTHEN packet (check keys)" so the most likely cause of this problem is key mismatch.

Answer: C
Explanation:
Explanation
Excessive time lag between Cisco DNA Center and device: The time difference between Cisco DNA Center and the device IP Address has drifted too far apart. CiscoDNA Center cannot process the device data accurately if the time difference is more than 3 minutes.
