Abigail is investigating slow web responses from a server for her online business. Which type of network analysis would help her identify whether the issue is client-side or server-side?

• Behavioral analysis

• Traffic flow analysis

• Vulnerability analysis

• Network enumeration

During a network performance review, Maya notices frequent retransmissions in the captured traffic. What could this indicate?

• Misconfigured DNS server

• Packet loss on the network

• High CPU usage on server

• Duplicate IP address

As a network administrator, you’re tasked with monitoring bandwidth usage between the headquarters and a remote office. Which network analysis focus area applies?

• Topology mapping

• Performance monitoring

• Security auditing

• Log analysis

A network admin named Aiden uses Wireshark to analyze packets from a DDoS attack. What kind of network analysis is being performed?

• Fault analysis

• Security analysis

• Load analysis

• Latency analysis

During a routine network check, Zoe notices unusual behavior in her LAN. She suspects ARP spoofing might be occurring. What data would confirm this?

• Large packet sizes

• Repeated DNS queries

• Duplicate MAC addresses for different IPs

• SYN flood patterns

During a network troubleshooting session, Arjun notices that a packet capture shows multiple TCP connections being reset (RST flag set). This typically indicates:

• Successful data transfers

• Connection interruptions

• ICMP redirections

• ARP cache poisoning

A security engineer named Liam captures traffic and sees payloads encrypted via TLS. Which statement is true?

• Full packet inspection can still read content

• Only metadata can be analyzed

• TCPdump can decrypt it automatically

• Layer 2 headers contain payload info

During a network maintenance session, Avery notices that packets are seen looping endlessly between routers. Which network issue is likely?

• DNS failure

• Routing loop

• ARP cache timeout

• MTU mismatch

While troubleshooting VoIP call issues at a busy call center, Arjun discovers that packets are delayed and arriving out of order during customer calls. The problem relates to:

• TCP handshake

• Jitter and latency

• DNS resolution

• Packet duplication

While monitoring a server, Sophia notices constant ICMP Echo requests. What could this mean?

• Port scanning activity

• DNS amplification

• SMTP relay

• TLS handshake failure
