A network administrator cannot establish a Telnet session with the indicated router. What is the cause of this failure?
A.
A Level 5 password is not set.
B.
An ACL is blocking Telnet access.
C.
The vty password is missing.
D.
The console password is missing.
First off, horrible image.
A. is incorrect. What do they mean by level 5 password? IS that level 5 privillaged password or level 5 line password? Either way wont solve problem.
B. is incorrect because the extended access list is blocking port 22 SSH. Telnet is port 23.
D. is incorrect because the console password is not missing, but it is encrypted.
C. is correct because you need a VTY password.
I had this on the exam today
Router(config)#line vty 0 4
Router(config-line)#login
Router(config-line)#password cisco
correct commmand like above
