- Question 1Networking
A technician needs to verify that a remote web server is accessible over a secure connection. Which default port should they test?
Show Answer & Explanation
Correct Answer: BExplanation:Port 443 is the default port for HTTPS, which provides secure encrypted web communication using TLS/SSL. Port 80 is for unencrypted HTTP, port 21 is FTP, and port 23 is Telnet.
- Question 2Select All That ApplyNetworking
Which of the following ports are associated with email services? (Choose TWO.)
Show Answer & Explanation
Correct Answers: A, CExplanation:Port 25 is used by SMTP for sending email, and port 110 is used by POP3 for retrieving email. Port 53 is DNS, and port 3389 is RDP (Remote Desktop Protocol).
- Question 3Networking
Which protocol uses port 53 and is responsible for translating domain names to IP addresses?
Show Answer & Explanation
Correct Answer: CExplanation:DNS (Domain Name System) operates on port 53 for both TCP and UDP and is responsible for resolving domain names into IP addresses. DHCP uses ports 67/68, LDAP uses port 389, and SNMP uses port 161.
- Question 4Networking
A technician needs to securely transfer files to a remote server. Which protocol should they use?
Show Answer & Explanation
Correct Answer: CExplanation:SFTP (SSH File Transfer Protocol) provides encrypted file transfers over SSH (port 22). FTP transmits data in cleartext on ports 20/21, TFTP uses UDP port 69 without encryption, and Telnet is an unencrypted remote access protocol.
- Question 5Networking
Which IEEE wireless standard operates exclusively on the 5 GHz band and supports a maximum theoretical throughput of 1.3 Gbps?
Show Answer & Explanation
Correct Answer: BExplanation:802.11ac (Wi-Fi 5) operates exclusively on the 5 GHz band and supports up to 1.3 Gbps with multiple spatial streams. 802.11n supports both 2.4 GHz and 5 GHz, while 802.11g and 802.11b use only 2.4 GHz.
- Question 6Networking
Which transport layer protocol provides connectionless, best-effort delivery and is commonly used for streaming media and DNS queries?
Show Answer & Explanation
Correct Answer: BExplanation:UDP (User Datagram Protocol) is a connectionless transport protocol that provides fast, best-effort delivery without guaranteed ordering or retransmission. It is used for DNS queries, streaming, and VoIP.
Key Networking Concepts for APLUS1
APLUS1 Networking Exam Tips
Networking Fundamentals questions in APLUS1 are typically scenario-based. Focus on service-level decision making aligned to official exam objectives. Priority concepts: tcp/ip, ports, protocols, router, switch, wireless.
What APLUS1 Expects
- Anchor your answer in select the most practical, secure, and scalable answer for the stated scenario.
- Networking scenarios for APLUS1 are frequently mapped to Domain 3 (25%), so read the objective carefully before picking controls or architecture.
- Expect multi-service scenarios where Networking interacts with IAM, networking, storage, or observability patterns rather than appearing as an isolated service question.
- When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Entry) and managed-service best practices.
High-Value Networking Concepts
- Know the core Networking building blocks cold: tcp/ip, ports, protocols, router.
- Review the edge-case features and limits for switch, wireless; these details are commonly used to differentiate answer choices.
- Practice service-integration reasoning: how Networking pairs with Hardware, Virtualization & Cloud in real deployment patterns.
- For APLUS1, explain why the chosen Networking design meets reliability, security, and cost expectations better than the alternatives.
Common APLUS1 Traps
- Watch for answers that partially solve the requirement but miss operational constraints.
- Questions in Hardware often include distractors that look correct for Networking but violate least-privilege, durability, or availability requirements.
- Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
- If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.
Fast Review Checklist
- Can you compare at least two Networking implementation paths and justify which one best fits the scenario?
- Can you map the chosen answer back to Hardware (25%) outcomes for APLUS1?
- Can you explain security and access boundaries for Networking without relying on default-open assumptions?
- Can you describe how Networking integrates with Hardware and Virtualization & Cloud during failure, scaling, and monitoring events?
