Here are the answers to Thursday morning's Cisco CCNA and CCNP practice questions.
CCNA:
Short answer: What's the L2 broadcast address?
Answer: The L2 broadcast address, or MAC broadcast address, is ff-ff-ff-ff-ff-ff-ff.
CCNP / BSCI:
Short answer: What is the Area ID of the ISIS address 49.0001.8912.8934.1923.1823.00 ?
Answer: 49.0001.8912. To determine the Area ID, work from right to left. "00" is the NSEL. The next six bytes from right to left are the System ID, which in this question is 8934.1923.1823. The remaining value is the Area ID.
CCNP / BCMSN:
Which of the following devices allow inter-VLAN communication?
A. Router
B. Multilayer Switch
C. L2 Switch
D. L3 Switch
E. Hub
Answer: A, B, D. Routers do , of course, as do Multilayer switches, which are also called L3 switches.
CCNP / BCRAN:
What is the process of deciding if a given user should have access to the network?
A. Authentication
B. Aggregation
C. Accounting
D. Authorization
Answer: A. The first step in AAA is authentication, which determines whether the user should be able to access the network.
CCNP / CIT:
What interface, if any, is created by default when PPP multilink is enabled on both endpoints of an ISDN connection?
A. An additional loopback interface
B. A virtual-terminal interface
C. A virtual-template interface
D. A virtual-access interface
E. No interface is created by enabling PPP multilink.
Answer: D. Configuring PPP multilink creates a virtual-access interface. The line shown below is from the output of debug ppp negotiation, whilc show interface virtual access verifies the creation.
*Mar 1 02:26:43.519: %LINK-3-UPDOWN: Interface Virtual-Access2, changed state to up
R1#show interface virtual-access2
Virtual-Access2 is up, line protocol is up
Hardware is Virtual Access interface
MTU 1500 bytes, BW 64 Kbit, DLY 100000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, LCP Open, multilink Open Open: CDPCP, IPCP
See you later this morning with more Cisco answers and questions!
