Question 43
What would have the highest administrative distance?
a) RIP
b) OSPF
c) EIGRP

Question 48
What should be used to test Ethernet cabling for continuity and pinout verification?
a) Crimper
b) OTDR
c) Wire map
d) Tone generator
Correct Answer: c) Wire map
Explanation: A wire map tester checks the continuity and pinout of Ethernet cables.
Question 49
What routing protocol allows routers to share incremental updates instead of full routing tables?
a) OSPF
b) EIGRP
c) RIP
d) BGP
Correct Answer: b) EIGRP
Explanation: EIGRP is a hybrid routing protocol that shares incremental updates instead of full routing tables.
Question 50
What IPv4 header field should a security engineer filter to investigate ARP-related traffic?
a) Source IP address
b) TTL
c) Protocol
d) Version
Correct Answer: c) Protocol
Explanation: ARP traffic is related to the protocol field in the IPv4 header, allowing ARP filtering to identify malicious traffic.
