NEW QUESTION 27
An engineer is troubleshooting on the console session of a router and turns on multiple debug commands. The console screen is filled with scrolling debug messages that none of the commands can be verified if entered correctly or display any output. Which action allows the engineer to see entered console commands while still continuing the analysis of the debug messages?
- A. Configure the logging synchronous command
- B. Configure the logging synchronous level all command
- C. Configure the term no mon command globally
- D. Configure the no logging console debugging command globally
Answer: A
Explanation:
Explanation
Let's see how the "logging synchronous" command affect the typing command:
Without this command, a message may pop up and you may not know what you typed if that message is too long. When trying to erase (backspace) your command, you realize you are erasing the message instead.
With this command enabled, when a message pops up you will be put to a new line with your typing command which is very

An engineer has configured R1 as EIGRP stub router. After the configuration, router R3 failed to reach to R2 loopback address.
Which action advertises R2 loopback back into the R3 routing table?
- A. Add a static route for R2 loopback address in R1 and redistribute it to advertise to R3.
- B. Add a static null route for R2 loopback address in R1 and redistribute it to advertise to R3.
- C. Use a leak map on R3 that matches the required prefix and apply it with the EIGRP stub feature.
- D. Use a leak map on R1 that matches the required prefix and apply it with the distribute list command toward R3.
Answer: D
Explanation:
Explanation
The EIGRP stub feature is useful to prevent unnecessary EIGRP queries and to filter some routes that you advertise. What if you want to configure your router as a stub router but still make an exception to some routes that it advertises? That is possible with the leak-map feature. This is how to configure leak-map in this question:
R1(config)#ip access-list standard R2_L0
R1(config-std-nacl)#permit host 2.2.2.2
R1(config)#route-map R2_L0_LEAK
R2(config-route-map)#match ip address R2_L0
R1(config)#router eigrp 1
R1(config-router)#eigrp stub leak-map R2_L0_LEAK
NEW QUESTION 32

The network administrator configured redistribution on an ASBR to reach to all WAN networks but failed Which action resolves the issue?
- A. The route map EIGRP->OSPF must have the 10.0.106.0/24 entry to exist in one of the three prefix lists to pass
- B. The OSPF process must have a metric when redistributing prefixes from EIGRP.
- C. EIGRP must redistribute the 10.0.106.0/24 route instead of using the network statement
- D. The route map must have the keyword prefix-list to evaluate the prefix list entries
Answer: D
Explanation:
In order to use a prefix-list in a route-map, we must use the keyword "prefix-list" in the "match" statement. . For example:
match ip address prefix-list WAN_PREFIXES
Without this keyword, the router will try to find an access-list with the same name instead.
NEW QUESTION 36
Exhibit:
NTP is configured across the network infrastructure and Cisco DNA Center. An NTP issue was reported on the Cisco DNA Center at 17:15. Which action resolves the issue?
- A. Reset the NTP server to resolve any synchronization issues tor all devices
- B. Check and resolve reachability between the WLC and the NTP server
- C. Check and configure NTP on the WLC and synchronize with Cisco DNA Center
- D. Check and resolve reachability between Cisco DNA Center and the NTP server
Answer: C
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.
NEW QUESTION 37 
Refer to the exhibit. A network administrator redistributed the default static route into OSPF toward all internal routers to reach to Internet. Which set of commands restores reachability to the Internet by internal routers?
- A. router ospf 1
redistribute connected 0.0.0.0 - B. router ospf 1
network 0.0.0.0 0.0.0.0 area 0 - C. router ospf 1

NEW QUESTION 38
Refer to the exhibit.
An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?
- A. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.
- B. The summary-address command is used only for summarizing prefixes between areas.
- C. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.
- D. The summary route is visible only in the OSPF database, not in the routing table.
Answer: C
Explanation:
Explanation
The summary-address is only used to create aggregate addresses for OSPF at an autonomous system boundary.
It means this command should only be used on the ASBR when you are trying to summarize externally redistributed routes from another protocol domain or you have a NSSA area. But a requirement to create a summarized route is:
The ASBR compares the summary route's range of addresses with all routes redistributed into OSPF on that ASBR to find any subordinate subnets (subnets that sit inside the summary route range). If at least one subordinate subnet exists, the ASBR advertises the summary route.
NEW QUESTION 39
Refer to the exhibit.
Redistribution is enabled between the routing protocols, and nowPC2 PC3, and PC4 cannot reach PC1. What are the two solutions to fix the problem? (Choose two.)
- A. Filter all routes except EIGRP routes when redistributing into OSPF in R3.
- B. Filter OSPF routes into RIP FROM EIGRP when redistributing into RIP in R2.
- C. Filter all routes except RIP routes when redistributing into EIGRP in R2.
- D. Filter RIP routes back into RIP when redistributing into RIP in R2
- E. Filter RIP AND OSPF routes back into OSPF from EIGRP when redistributing into OSPF in R2
Answer: C,D
Explanation:
Explanation
Even PC2 cannot reach PC1 so there is something wrong with RIP redistribution in R2. Because RIP has higher Administrative Distance (AD) value than OSPF and EIGRP so it will be looped when doing mutual redistribution.
