Welcome! Here are the answers to Thursday's Cisco CCNA and CCNP exam practice questions!
CCNA Certification Exam:
Two OSPF routers connected via an Ethernet segment are exchanging Hello packets. How often will these packets be sent?
A. Every 5 seconds.
B. Every 10 seconds.
C. Every 30 seconds.
D. Every 120 seconds.
E. OSPF speakers do not send Hellos on an Ethernet segment.
Answer: B. On a broadcast network such as an Ethernet segment, OSPF speakers send hellos every 10 seconds, as shown below.
R2#show ip ospf interface ethernet0
Ethernet0 is up, line protocol is up
Internet Address 172.23.23.2/27, Area 23
Process ID 1, Router ID 2.2.2.2, Network Type BROADCAST, Cost: 10 Transmit Delay is 1 sec, State BDR, Priority 1
Designated Router (ID) 3.3.3.3, Interface address 172.23.23.3 Backup Designated router (ID) 2.2.2.2, Interface address 172.23.23.2
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
CCNP Certification / BSCI Exam:
A non-Cisco router will consider what value first during the BGP best path selection process?
A. weight
B. AS_PATH
C. LOCAL_PREF
D. origin
E. MED
F. RID
Answer: C. Weight is considered first, but weight is Cisco-proprietary. A non-Cisco router will not understand the weight attribute, so local preference (LOCAL_PREF) is then used.
CCNP Certification / BCMSN Exam:
Short answer: Identify and briefly describe the port security modes.
Answer: Protect drops data with non-secure MAC addresses; Restrict does the same while generating a syslog message; Shutdown places the port into error-disabled mode.
CCNP Certification / ISCW Exam:
Identify the true statements regarding IPSec Transport mode.
A. Uses the original IP header
B. Replaces the original IP header with a transport header
C. The IP header is encrypted
D. The IP header is not encrypted
Answers: A, D. Transport mode uses the original IP header, and the IP header is not encrypted.
CCNP Certification / ONT Exam:
What term refers to traffic being dropped because the queue is full?
Answer: That's tail drop, which can lead to all sorts of problems, which we'll talk about in future blog postings!
New questions later today!
