Soru 424Soru

A network technician is diagnosing several client host issues across a enterprise corporate network. Match each network diagnostic scenario on the left with the corresponding IP addressing condition or configuration failure on the right.

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Öğeler

A workstation interface receives an IP address of 169.254.112.45 with subnet mask 255.255.0.0 upon boot and loses connection to internal network shares.
A static host with IP address 10.20.30.15/24 can successfully ping local hosts on 10.20.30.0/24, but cannot communicate with hosts on remote subnets.
A client host can successfully ping external servers using their direct IP address (e.g., 8.8.8.8), but web browsers fail to load sites using domain names.
A workstation network interface automatically generates a non-routable unicast address starting with `fe80::` for local segment traffic.

Eşleşmeler

Cevabı ve açıklamayı göster

Cevap

The diagnostic scenarios correspond to their root configuration causes as follows: 1) 169.254.x.x assignment indicates APIPA due to DHCP failure; 2) Subnet-only communication points to a missing or invalid default gateway; 3) IP connectivity without domain access indicates a DNS configuration error; 4) fe80:: prefix represents IPv6 Link-Local auto-configuration.
Each scenario maps to a fundamental network diagnostic principle: APIPA (169.254.x.x) occurs when DHCP discovery times out; default gateway misconfiguration permits local communications while blocking external routing; DNS issues break hostname resolution while preserving direct IP connectivity; and the fe80:: block signifies standard IPv6 link-local auto-configuration.

Adım Adım Çözüm

1
Examine Scenario 1 (Address 169.254.112.45)
Identify 169.254.0.0/16 as the IANA reserved APIPA block.
When a DHCP client cannot obtain an IP lease, the host OS auto-assigns an APIPA link-local IPv4 address.
2
Examine Scenario 2 (Local ping success, remote ping failure)
Identify a missing route out of the local network segment.
Traffic destined outside the local broadcast domain requires a default gateway IP to route packets.
3
Examine Scenario 3 (Direct IP ping success, domain lookup failure)
Separate layer-3 IP connectivity from layer-7 hostname resolution.
Pinging numeric IP addresses bypasses DNS; failure to load websites by hostname indicates domain name resolution issues.
4
Examine Scenario 4 (fe80:: prefix address generation)
Identify IPv6 Link-Local address characteristics.
IPv6 automatically configures an fe80:: link-local address on all enabled interfaces for local link communication.

Cevabı ve açıklamayı göster

Cevap

APIPA IPv4 Address Range matches 169.254.0.1 to 169.254.255.254 link-local address assigned when DHCP fails; Default Gateway matches Forwards network traffic destined for hosts outside the local subnet; Subnet Mask matches Distinguishes the network portion from the host portion of an IP address; DNS Server matches Translates human-readable domain names into numerical IP addresses.
Each IP network component performs a distinct function: APIPA addresses fall within the 169.254.0.1 to 169.254.255.254 range for self-configuration during DHCP outages; the default gateway handles routing off the local segment; the subnet mask delineates network and host portions of an address; and the DNS server performs hostname-to-IP resolution.

Adım Adım Çözüm

1
Identify the characteristic behavior of APIPA
APIPA provides fallback addresses in the 169.254.0.0/16 block when dynamic assignment fails
APIPA allows local communication without external network access
2
Identify the role of a Default Gateway
It serves as the exit router for remote destination traffic
Traffic bound for foreign subnets must pass through a designated routing interface
3
Identify the purpose of a Subnet Mask

Identify the primary mail transfer protocol used for sending messages.
SMTP uses TCP port 25 for sending and relaying emails.
SMTP is designated specifically for outbound message transport.
2
Differentiate local email download from server-synced email management.
POP3 uses TCP port 110 to download messages locally, while IMAP uses TCP port 143 to keep messages stored and synchronized on the server.
POP3 downloads and typically deletes messages from the server, whereas IMAP maintains two-way folder synchronization.

Cevap

Qi Wireless Charging matches power transfer via magnetic induction without physical contacts; USB Type-C with Thunderbolt matches the 24-pin reversible interface supporting 40 Gbps bandwidth and video output; Apple Lightning Port matches the 8-pin reversible proprietary connector design; Micro-USB Port matches the asymmetrical 5-pin connector limited to legacy USB 2.0 speeds.
Qi wireless charging operates using electromagnetic induction between internal coils without requiring plug-in wire contacts. USB Type-C with Thunderbolt utilizes a 24-pin reversible connector capable of multiplexing high-speed 40 Gbps data, DisplayPort video, and power delivery. The Apple Lightning connector is an 8-pin reversible proprietary digital interface. The Micro-USB port is an asymmetrical 5-pin connector standard designed for older mobile devices operating at USB 2.0 speeds.

Adım Adım Çözüm

1
Analyze the physical connector pin counts and insertion geometry for wired interfaces
Identify USB Type-C as 24-pin reversible, Lightning as 8-pin reversible, and Micro-USB as 5-pin asymmetrical.
Physical pin configurations and symmetry distinguish different mobile physical ports.
2
Evaluate data throughput and protocol tunneling capabilities for each interface
USB Type-C with Thunderbolt support handles up to 40 Gbps throughput, Power Delivery, and DisplayPort signals. Micro-USB handles standard USB 2.0 rates.
Protocol support and transfer rates depend on connector design and internal controller hardware.

TCP Port 636

Cevap

TCP Port 636 matches Secure identity authentication and directory query services encrypted via SSL/TLS (LDAPS); UDP Port 69 matches Connectionless bootstrap and firmware file transmission without user authentication (TFTP); TCP Port 445 matches Direct network file and printer sharing directly over TCP/IP networks (SMB); UDP Port 161 matches Querying system metrics and hardware status from managed network devices (SNMP).
TCP port 636 provides secure directory services via LDAPS. UDP port 69 handles unauthenticated bootstrap/firmware file transfers via TFTP. TCP port 445 supports direct SMB file and printer sharing over IP. UDP port 161 receives SNMP polling requests for device status metrics.

Adım Adım Çözüm

1
Identify secure authentication protocols
LDAP unencrypted operates on TCP 389, whereas encrypted LDAPS uses TCP port 636.
Secure directory services require SSL/TLS binding, which defaults to port 636.
2
Distinguish between file transfer mechanisms
FTP uses TCP ports 20/21 and requires credentials, while TFTP uses UDP port 69 for unauthenticated simple transfers.
TFTP relies on UDP for lightweight overhead when sending router configuration or boot files.
3
Differentiate file sharing and transport protocols
SMB operates natively over TCP port 445 without NetBIOS overhead.
Legacy NetBIOS over TCP/IP used ports 137-139, but modern direct SMB uses TCP 445.
4
Analyze network management port allocations
SNMP queries use UDP port 161, while SNMP trap notifications use UDP port 162.
Device status polling occurs on UDP 161.
