Here are the answers to Tuesday's CCNA, CCNP, and Network+ certification exam practice questions!
CCNA:
Short answer: What is the range of addresses reserved for multicasting? What class do these addresses belong to?
Answer: The reserved multicast address class is Class D, and that range is 224.0.0.0 - 239.255.255.255.
Network +:
Which of the following network topologies commonly use terminators?
A. ring
B. bus
C. star
D. hybrid
Answer: B. Of the above, only bus topologies use terminators.
CCNP / BSCI:
A stub router's OSPF routing table can contain which of the following?
A. inter-area routes
B. intra-area routes
C. E2 routes
D. E1 routes
E. A default route using the ABR as the next hop
Answers: A, B, E. A stub area's routing table can contain intra-area routes (O), inter-area routes (O IA), and a default route using the ABR as the next hop ( O IA*). The default route is used to reach external destinations.
A stub routing table will not contain E1 or E2 routes.
A typical OSPF stub routing table:
R4#show ip route ospf
1.0.0.0/32 is subnetted, 1 subnets
O IA 1.1.1.1 [110/75] via 172.34.34.3, 00:01:07, Ethernet0
172.12.0.0/24 is subnetted, 1 subnets
O IA 172.12.123.0 [110/74] via 172.34.34.3, 00:01:07, Ethernet0
O*IA 0.0.0.0/0 [110/11] via 172.34.34.3, 00:01:07, Ethernet0
CCNP / BCMSN:
What ACL type should be used to filter bridged traffic?
A. extended ACL
B. VLAN ACL
C. bridged ACL
D. TCAM ACL
E. switched ACL
Answer: B. Use a VLAN ACL to filter bridged traffic.
CCNP / BCRAN:
Authentication, callback, compression, and multilink PPP are all options of what ISDN protocol?
A. NCP
B. LCP
C. PAP
D. CHAP
Answer: B. Authentication, callback, compression, and multilink PPP are all Link Control Protocol features.
CCNP / CIT:
What's the most effective way to ensure the TCP/IP stack is correctly installed on your PC?
A. Telnet to 127.0.0.1
B. Run a traceroute to 127.0.0.1
C. Ping 127.0.0.1
D. Run a tracert to 127.0.0.1
Answer: C. Always start PC troubleshooting by pinging the PC's loopback address, 127.0.0.1
