(ICMP packets do not contain port numbers. Therefore, NAPT cannot be used.)
- A. FALSE
- B. TRUE
Answer: A
Explanation:
* ICMP and NAPT:ICMP packets do not have port numbers, but NAPT (Network Address and Port Translation) can still manage ICMP traffic by matching identifiers in the ICMP header. This allows NAPT to handle ICMP messages properly.
* Correct answer:FALSE. ICMP packets can be handled by NAPT.

(Which of the following is a dynamic IGP routing protocol?)
- A. BGP
- B. Direct
- C. Static
- D. OSPF
Answer: D
Explanation:
* Dynamic IGP Routing Protocols:
* OSPF (Open Shortest Path First): A dynamic IGP that uses link-state information for routing within an autonomous system.
* Analysis of Options:
* Option A: "Static" refers to manually configured routes, not dynamic.
* Option B: "BGP" is a dynamic routing protocol but an EGP, not an IGP.
* Option C: "Direct" refers to routes learned from directly connected networks and is not dynamic.
* Option D: "OSPF" is a dynamic IGP, making it the correct choice.
* Correct answer:The dynamic IGP routing protocol is D (OSPF).
NEW QUESTION # 141
An ACL rule is as follows. Which of the following IP addresses can be matched by the permit rule?
Rule: rule 5 permit ip source 10.0.2.0 0.0.254.255
- A. 10.0.5.6
- B. 10.0.6.7
- C. 10.0.2.1
- D. 10.0.4.5
Answer: C
Explanation:
* The wildcard mask 0.0.254.255 means:
* The first and third octets are checked exactly.
* The second and fourth octets can vary.
* This results in a match for IPs in the range 10.0.2.0 - 10.0.2.255.
* Only option D (10.0.2.1) falls within this range.
Thus, the correct answer is D (10.0.2.1).
