What command instructs the device to timestamp Syslog debug messages in milliseconds?
A. service timestamps log datetime localtime<input type
B. service timestamps debug datetime msec<input type
C. service timestamps debug datetime localtime<input type
D. service timestamps log datetime msec
Answer: B
Explanation:
Enable millisecond (msec) timestamps using the service timestamps command: router(config)#service timestamps debug datetime msec.
router(config)#service timestamps log datetime msec The “service timestamps debug”. command configures the system to apply a time stamp to debugging messages. The time- stamp format for datetime is MMM DD HH:MM:SS, where MMM is the month, DD is the date, HH is the hour (in 24-hour notation), MM is the minute, and SS is the second. With the additional keyword msec, the system includes milliseconds in the time stamp, in the format HH:DD:MM:SS.mmm, where .mmm is milliseconds.

Refer to the graphic.
R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.)
A. All of the routers need to be configured for backbone Area 1.
B. R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.
C. A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.
D. The hello and dead interval timers are not set to the same values on R1 and R3.
E. EIGRP is also configured on these routers with a lower administrative distance.
F. R1 and R3 are configured in different areas.
Answer: D,F
Explanation:
This question is to examine the conditions for OSPF to create neighborhood.
So as to make the two routers become neighbors, each router must be matched with the following items:
1. The area ID and its types;
2. Hello and failure time interval timer;
3. OSPF Password (Optional).

A network administrator needs to allow only one Telnet connection to a router. For anyone viewing the configuration and issuing the show run command, the password for Telnet access should be encrypted. Which set of commands will accomplish this task?
A. service password-encryption
access-list 1 permit 192.168.1.0 0.0.0.255
line vty 0 4 login
password cisco access-class 1
B. enable password secret line vty 0
login
password cisco
C. service password-encryption line vty 1
login
password cisco
D. service password-encryption line vty 0 4
login
password cisco
Answer: C
Explanation:
Only one VTY connection is allowed which is exactly what's requested. Incorrect Answer: command.
line vty0 4
would enable all 5 vty connections.

Q67. - (Topic 4)
Which two statistics appear in show frame-relay map output? (Choose two.)
A. the number of BECN packets that are received by the router
B. the value of the local DLCI
C. the number of FECN packets that are received by the router
D. the status of the PVC that is configured on the router
E. the IP address of the local router
Answer: B,D
Explanation:
Sample “show frame-relay map” output: R1#sh frame map
Serial0/0 (up): ip 10.4.4.1 dlci 401(0x191,0x6410), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.3 dlci 403(0x193,0x6430), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.4 dlci 401(0x191,0x6410), static, CISCO, status defined, active
