NEW QUESTION 53
Refer to the exhibit.
A company is evaluating multiple network management system tools. Trending graphs generated by SNMP data are returned by the NMS and appear to have multiple gaps. While troubleshooting the issue, an engineer noticed the relevant output. What solves the gaps in the graphs?
- A. Remove the exceed-rate command in the class map.
- B. Configure the CIR rate to a lower value that accommodates all the NMS tools
- C. Remove the class map NMS from being part of control plane policing.
- D. Separate the NMS class map in multiple class maps based on the specific protocols with appropriate CoPP actions
Answer: D
NEW QUESTION 54
What is the minimum time gap required by the local system before putting a BFD control packet on the wire?
- A. Desired Min TX Interval
- B. Detect Mult
- C. Required Min RX Interval
- D. Required Min Echo RX Interval
Answer: A
Explanation:
Desired Min TX Interval: This is the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets, less any jitterapplied. The value zero is reserved.
Required Min Echo RX Interval: This is the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting, less anyjitter applied by the sender. If this value is zero, the transmitting system does not support the receipt of BFD Echo packets.
NEW QUESTION 55
Refer to the exhibit. A network administrator configured NTP on a Cisco router to get synchronized time for system and logs from a unified time source The configuration did not work as desired Which service must be enabled to resolve the issue?
- A. Enter the service timestamps log datetime clock-period global command
- B. Enter the service timestamps log datetime localtime global command.
- C. Enter the service timestamps log datetime console global command.
- D. Enter the service timestamps log datetime synchronize global command.
Answer: D
NEW QUESTION 56
Refer to the exhibit.
An engineer is trying to redistribute OSPF to BGP, but not all of the routes are redistributed. What is the reason for this issue?
- A. Only classful networks are redistributed from OSPF to BGP
- B. BGP convergence is slow, so the route will eventually be present in the BGP table
- C. By default, only internal routes and external type 1 routes are redistributed into BGP
- D. By default, only internal OSPF routes are redistributed into BGP
Answer: D
Explanation:
If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area and inter-area routes are redistributed into BGP, by default.
You can redistribute both internal and external (type-1 & type-2) OSPF routes via this command: -Router(config-router)#redistribute ospf 1 match internal external 1 external 2
NEW QUESTION 57

- A. Use the same AD for both default routes
- B. Start IP SLA by matching numbers for track and ip sla commands

NEW QUESTION 60
Exhibit:
BGP is flapping after the Copp policy is applied. What are the two solutions to fix the issue?
(Choose two)
- A. Configure a higher value for CIR under the class COPP-CRITICAL-7600
- B. Configure IP CEF to CoPP policy and BGP to work
- C. Configure a three-color policer instead of two-color policer under class COPP-CRITICAL-
7600 - D. Configure a higher value for CIR under the default class to allow more packets during peak traffic
- E. Configure BGP in the COPP-CRITICAL-7600 ACL
Answer: D,E
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 61
Drag and drop the OSPF adjacency states from the left onto the correct descriptions on the right.
Answer:
Explanation:
Explanation
Exchange = Each router compares the DBD packets that were received from the other router
2-way = Router exchange information with other routers in the multiaccess network Loading = The neighboring router requests the other routers to send missing entries Exstart = The network has already elected a DR and a backup BDR Init = The OSPF router ID of the receiving router was not contained in the hello message Down = No hellos have been received from a neighbor router
NEW QUESTION 62 
Refer to the exhibit. Which statement about R1 is true?
- A. RIP learned routes are distributed to OSPF with a tag value of one.
- B. RIP routes are redistributed to OSPF without any changes.
- C. OSPF redistributes RIP routes only if they have a tag of one.
- D. R1 adds one to the metric for RIP learned routes before redistributing to OSPF.
Answer: A

Section: Layer 3 Technologies
NEW QUESTION 63
Refer to the exhibit.
A router receiving BGP routing updates from multiple neighbors for routers in AS 690. What is the reason that the router still sends traffic that is destined to AS 690 to a neighbor other than 10.222.1.1?
- A. The local preference value should be set to the same value as the weight in the route map.
- B. The local preference value in another neighbor statement is higher than 250.
- C. The route map is applied in the wrong direction.
- D. The weight value in another neighbor statement is higher than 200.
Answer: C
NEW QUESTION 64
Refer to the exhibit.

- A. policy-map LIMIT_BGP
- B. policy-map POLICE_BGP
- C. policy-map COPP
- D. policy-map SHAPE_BGP
Answer: C
NEW QUESTION 65
Refer to the exhibit.
An engineer configures a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen. What is the reason for this?
- A. The syntax of the static route is not valid, so the route is not considered.
- B. Dynamic routing protocols always have priority over static routes.
- C. The metric of the OSPF route is lower than the metric of the static route.
- D. The configured AD for the static route is higher than the AD of OSPF.
Answer: D
Explanation:
Explanation
The AD of static route is manually configured to 130 which is higher than the AD of OSPF router which is
110.
NEW QUESTION 66

NEW QUESTION 68
An engineer configured a DHCP server for Cisco IP phones to download its configuration from a TFTP server, but the IP phones failed to toad the configuration What must be configured to resolve the issue?
- A. BOOTP port 67
- B. DHCP option 66
- C. DHCP option 69
- D. BOOTP port 68
Answer: B
Explanation:
DHCP options 3, 66, and 150 are used to configure Cisco IP Phones. Cisco IP Phones download their configuration from a TFTP server. When a Cisco IP Phone starts, ifit does not have both the IP address and TFTP server IP address preconfigured, it sends a request with option 150 or 66 to the DHCP server to obtain this information.+ DHCP option 150 provides the IP addresses of a list of TFTP servers.+ DHCP option 66 gives the IP address or the hostname of a single TFTP server.

HTTP and HTTPs run on TCP port 80 and 443, respectively and we have to remember them.
Syslog runs on UDP port 514 while NTP runs on UDP port 123 so if we remember them we can find out the matching answers easily. But maybe there is some typos in this question as 2001:d88:800:200c::c/126 only ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f (4 hosts in total). It does not cover host 2001:0D88:0800:200c::1f. Same for 2001:D88:800:200c::e/126, which also ranges from
2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f and does not cover host 2001:0D88:0800:200c::1c
