Refer to the exhibit. Which action resolves the authentication problem?
Answer: A
Reference: https://www.cisco.com/c/en/us/support/docs/security-vpn/terminal-access-controller-access-control-system-tacacs-/200467-Troubleshoot-TACACS-Authentication-Issue.html This is a sample debug output from the Router, when the TACACS server is configured with a wrong pre shared key.

Refer to the exhibit. R1 is configured with uRPF, and ping to R1 is failing from a source present in the R1 routing table via the GigabitEthernet 0/0 interface. Which action resolves the issue?
Answer: B
with uRPF strict mode, this can cause legitimate packets to be dropped, so that's something to keep in mind. In uRPF loose mode, the source of the IP packet must simply appear in the routing table. So loose mode looks for any interface in the routing table other than the default route.

Refer to the exhibit. A bank ATM site has difficulty connecting with the bank server. A network engineer troubleshoots the issue and finds that R4 has no active route to the bank ATM site. Which action resolves the issue?
Answer: D
The LAN on R1 goes unreachable. => R1 starts querying for a path for prefix 10.20.10.0/24. (R1 is active for this prefix.) After this, the routers R2 and R3 also go active and query. "show ip eigrp topology active" -> Look for the small r in the command output. This means that the router awaits a reply to a query for that prefix from that neighbor. The R3 also goes active and awaits a reply from R4. As shown, the router R4 does not go active for the prefix, because it did not recieve any queries. So, there must be an issue with the link between R3 and R4. For same reason, R3 does not receive an SIA reply from R4, so the "s" appears for that neighbor under "show ip eigrp topology active". rs = r - reply Status, s - sia Status sent query and waiting for reply + did not recieve reply in SIA time

What is an advantage of using BFD?
Answer: D
I Go for D just following reasion A. It detects local link failure at layer 1 and updates the routing table. WRONG - BFD detects local link failures, but BFD does not interact with the routing table WRONG B. It detects local link failure at layer 3 and updates the routing protocols. (ALMOST RIGHT BUT WRONG) - The question here is What is the advantage of using BFD. routing procols can detect local link failures, so this is not an advantage. C. It has sub-second failure detection for layer 1 and layer 3 problems. WRONG TRICKY' - sub second failure detection is an advange of BFD, but BFD only detects L1-L2 problems, ink itself, BFD can not detect L3 problem like address misconfig. D. It has sub-second failure detection for layer 1 and layer 2 problems. RIGHT!! - The advantage of BFD is it's sub-second failure detection, and just detect L1-L2 problems.

Refer to the exhibit.
The BGP neighbor is not coming up. Which action resolves the issue?
Answer: A
A - 192.168.200.6 can be reached via 192.168.100.1, so at least 2 hops needed B - remote RID 0.0.0.0 just tells that there's no TCP connection, and it's given on the pic C - I don't see any route map here D - this has nothing to do w/ the no sync command

Refer to the exhibit. After recovering from a power failure, Ethernet0/1 stayed down while Ethernet0/0 returned to the up/up state. The default route through ISP1 was not reinstated in the routing table until Ethernet0/1 also came up. Which action resolves the issue?
Answer: A
IP SLA operation to check ISP-1 should not rely on ISP-2 interface/connection--reach 8.8.8.8 via ISP-2 in this case. in this case either; - the address for icmp-echo should be changed to 203.0.113.1 OR - Add static route 8.8.8.8/32 -->203.0.113.1

Refer to the exhibit. Which action resolves the issue?
Answer: D
Looking at the configuration, it seems that there are two SNMP community strings configured, "public" and "private". However, the configuration does not specify which community string is being used by the host with IP address 10.1.1.1. The correct action to resolve this issue would be to configure a valid SNMP community string on the device from which the SNMP request is being made, and ensure that it matches the community string configured on the router.

Refer to the exhibit. An administrator is attempting to disable the automatic logout after a period of inactivity. After logging out, the console stopped responding to all keyboard inputs. Remote access through SSH still works. Which action resolves the issue?
Answer: C
Why should configuring the exec-timeout fix the disabled exec? I would vote C to "resolv the issue" of console stopped responding to all keyboards. https://community.cisco.com/t5/routing/no-exec/td-p/3715737

Refer to the exhibit. Routers R1 and R2 have established a network adjacency using EIGRP, and both routers are advertising subnets to its neighbor. After issuing the show ip EIGRP topology all-links command in R1, some prefixes are not showing R2 as a successor. Which action resolves the issue?
Answer: A
Answer is A Can't be B, because if it has been the case, no route at all from R2 would have been learned Can't be C, because a metric mismatch leads in no neighbor relationship and we have Can't be D, Split horizon is enabled by default and it just avoid sharing the network via a same interface it received. It means i can GET routes from R2 but not just sharing them back to R2 via the same interface.

An engineer configures PBR on R5 and wants to create a policy that matches traffic destined toward 10.10.10.0/24 and forwards it toward 10.1.1.1. This traffic must also have its IP precedence set to 5. All other traffic should be forwarded toward 10.1.1.2 and have its IP precedence set to 0. Which configuration meets the requirements?
Answer: A
Correct, you need to define a source and destination for the Access-list, and two route maps to match each of the parameters for that destination and to be manipulated for the next-hop
