  • - Cost based on link bandwidth
  • - Hop count
  • - Delay and reliability
  • - Administrative distance

Câu 6: What is the primary benefit of implementing Virtual LANs (VLANs) in an enterprise network?

  • - To segment broadcast domains and improve network security
  • - To increase the physical speed of the network cables
  • - To encrypt traffic between switches
  • - To translate private IP addresses to public IP addresses

Câu 7: In advanced network routing, which addressing methodology routes a single IP address to the nearest topological node among a distributed group of servers?

  • - Broadcast
  • - Anycast
  • - Multicast
  • - Unicast

Câu 8: Which of the following accurately describes the structure of a standard MAC address?

  • - A dynamically assigned alphanumeric string
  • - A 128-bit hexadecimal number separated by colons
  • - A 48-bit hexadecimal number typically separated by colons or hyphens
  • - A 32-bit dotted-decimal number

Câu 9: What is the primary benefit of implementing Virtual Local Area Networks (VLANs) on a switch?

  • - They logically segment broadcast domains to improve network performance and security
  • - They translate private IP addresses to public IP addresses
  • - They encrypt traffic between the switch and the router
  • - They physically connect multiple switches together to increase bandwidth

Câu 10: How many bits does an IPv6 address consist of?

  • - 64 bits
  • - 32 bits
  • - 128 bits
  • - 256 bits

Câu 11: During the DORA process in DHCP, which message does a client broadcast initially to find available DHCP servers?

  • - DHCPDISCOVER
  • - DHCPOFFER
  • - DHCPREQUEST
  • - DHCPACK

Câu 12: Which type of transmission medium uses light pulses to transmit data over long distances with high bandwidth and immunity to electromagnetic interference?

  • - Unshielded Twisted Pair (UTP) cable
  • - Microwave radio
  • - Fiber optic cable
  • - Coaxial cable

Câu 13: What is the standard fixed length of a Media Access Control (MAC) address?

  • - 32 bits
  • - 48 bits
  • - 64 bits
  • - 128 bits

Câu 14: What network parameter must be configured on a host device so it can communicate with devices on a different subnet?

  • - VLAN ID
  • - Loopback address
  • - Default Gateway
  • - MAC address

Câu 15: While SMTP is universally used to send emails outward, which protocol is widely implemented by modern email clients to retrieve and synchronize messages from a mail server?

  • - SNMP
  • - FTP
  • - IMAP
  • - TFTP

Câu 16: In traditional active mode File Transfer Protocol (FTP), which two specific TCP ports are normally utilized for control signals and data connections respectively?

  • - 22 and 23
  • - 21 and 20
  • - 80 and 443
  • - 25 and 110

Câu 17: Which underlying protocol does the 'ping' command use to test reachability between two network devices?

  • - UDP
  • - TCP
  • - ICMP
  • - ARP

Câu 18: A traditional stateless network firewall primarily analyzes and filters incoming and outgoing traffic based on which specific header criteria?

  • - Source/destination IP addresses and port numbers
  • - Deep packet inspection of application payloads
  • - Biometric user authentication credentials
  • - The physical MAC address of the final destination

Câu 19: Which IEEE standard mathematically represents the wireless networking technology commonly known as Wi-Fi 6?

  • - 802.11ac
  • - 802.11n
  • - 802.11ax

  • - Frequency Division Multiple Access (FDMA)
  • - Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)
  • - Time Division Multiplexing (TDM)
  • - Token Passing

Câu 21: In IPv4, which address block is reserved specifically for local loopback testing and cannot be routed on the internet?

  • - 10.0.0.0/8

  • - Dynamic Host Configuration Protocol (DHCP)
  • - Network Address Translation (NAT)
  • - Spanning Tree Protocol (STP)
  • - Border Gateway Protocol (BGP)

Câu 23: Unlike a legacy network hub, what does a modern layer 2 network switch do to significantly improve performance in an Ethernet environment?
