Here are the answers to yesterday's questions!
CCNA Certification And CCENT Certification:
You look in the running config to check a banner you just created, and you see the strange characters as shown below. Are they a problem? Will the user see them? How did they get there?
banner login^C
Unauthorized Access Prohibited By Law. But You Knew That. ^C
banner motd ^C
Network down for router IOS upgrade at 10 PM EST tonight! ^C
Answer: That's what your delimiting character will look in the configuration. They're no problem, and they will not be displayed in the banner during use.
You're in SDM and want to perform a one-step router lockdown. Take a look at the following screen shot and tell me where you should click next.
Answer: Click the Security Audit button. You'll see the following screen at that point - note the mention of one-step lockdown.
CCNP Certification / BSCI Exam:
R1 is a route reflector. R1 receives an update from one of its RR clients. To what router type(s) will R1 reflect that route?
A. All clients, no non-clients.
B. All clients and non-clients.
C. All clients and non-clients, but no eBGP peers.
D. All clients, non-clients, and eBGP peers.
Answer: B. From the route reflector's point of view....
Updates from RR clients are sent to all client and nonclient peers.
Updates from eBGP peers are sent to all client and nonclient peers.
Updates from nonclient peers are sent to all clients in the cluster.
CCNP Certification / BCMSN Exam:
Is the following configuration valid? If not, what's wrong with it? What should we expect to see when we take a look at the Etherchannel's status?
interface FastEthernet0/11
switchport trunk allowed vlan 10,20
no ip address
channel-group 1 mode on
!
interface FastEthernet0/12
switchport trunk allowed vlan 100,200
no ip address
channel-group 1 mode on
Answer: There is a problem with this config - the two interfaces that have been placed into the Etherchannel are allowing different VLANs, which will result in this message:
02:46:10: %EC-5-CANNOT_BUNDLE2: Fa0/12 is not compatible with Fa0/11 and will be suspended (vlan mask is different)
Interestingly enough, port fast0/12 is not going to go into err-disabled mode; instead, you see this:
SW1#show int fast 0/12
FastEthernet0/12 is up, line protocol is down (notconnect)
When I remove the original command, I get the EC error message again, but once I change port 0/12's config to match 0/11's, the EC forms.
SW1(config)#int fast 0/12
SW1(config-if)#no switchport trunk allowed vlan 100,200
02:51:15: %EC-5-CANNOT_BUNDLE2: Fa0/12 is not compatible with Fa0/11 and will be suspended (vlan mask is different)
02:51:15: %EC-5-CANNOT_BUNDLE2: Fa0/12 is not compatible with Fa0/11 and will be suspended (vlan mask is different)chport
SW1(config-if)#switchport trunk allowed vlan 10,20
02:51:25: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/12, changed state to up
CCNP / ONT Exam: (My ONT Study Package will be out later this week!)
The sum of what four delay types equal the overall end-to-end delay?
Answer: Serialization, propagation, queueing, and processing.
That's it for today! Enjoy your day, and I'll see you Thursday!
To your success,
