   What should a network administrator consider when deciding to implement automation?

   • AAutomated systems may have difficulty expanding network changes at scale.
   • BNetwork automation typically is limited to the configuration and management of virtual devices within a network.
   • CNetwork automation typically increases enterprise management operating costs.
   • DManual changes frequently lead to configuration errors and inconsistencies.

   Show answer

   Answer: D

   Explanation

   D. Manual changes frequently lead to configuration errors and inconsistencies. When deciding to implement automation, a network administrator should consider the benefits and challenges associated with automation. Option D highlights one of the key reasons for implementing automation—manual changes often result in configuration errors and inconsistencies. Automating repetitive and error-prone tasks can help improve the accuracy and reliability of network configurations. Options A, B, and C do not accurately represent the typical considerations for implementing automation: A. Automated systems are designed to handle changes at scale efficiently, and the ability to scale is often one of the advantages of automation. B. Network automation is not limited to virtual devices; it can be applied to both physical and virtual devices within a network. C. While there may be some upfront costs associated with implementing automation, the goal is often to improve efficiency and reduce operating costs in the long run. Therefore, option D is the most appropriate consideration when deciding to implement automation in a network.

2. Question 252 · 1334 in bank

   Why is UDP more suitable than TCP for applications that require low latency such as VoIP?

   • AUDP reliably guarantees delivery of all packets: TCP drops packets under heavy load
   • BUDP uses sequencing data for packets to arrive in order TCP offers the capability to receive packets in random order
   • CTCP uses congestion control for efficient packet delivery: UDP uses flow control mechanisms for the delivery of packets
   • DTCP sends an acknowledgement for every packet received: UDP operates without acknowledgments

   Show answer

   Answer: D

   Explanation

   Ther correct answer is "D", - But there is a typo in "every *packet* received". It should be ("every *segments* received" - Layer 4 - Transport) - Even though, letter "D" is a correct Answer. 1. The PDU of "Transport" Layer is called as a "Segment". 2. The PDU of "Network" Layer is called as a "Packet". 3. The PDU of the "Data-Link" Layer is called "Frames".

   How does IPsec provide secure networking for applications within an organization?

   • AIt takes advantage of FTP to secure file transfers between nodes on the network.
   • BIt provides GRE tunnels to transmit traffic securely between network nodes.
   • CIt enables sets of security associations between peers.
   • DIt leverages TFTP providing secure file transfers among peers on the network.

   Show answer

   Answer: C

   Explanation

   C. It enables sets of security associations between peers. IPsec (Internet Protocol Security) is a protocol suite that provides secure communication over Internet Protocol (IP) networks. It achieves this by authenticating and encrypting each IP packet within a communication session. One of the key concepts in IPsec is the establishment of security associations (SAs) between peers. Security associations are the combination of algorithms and keys used to secure communication between two devices. They define the security parameters for the communication, including the encryption algorithm, integrity algorithm, and keying information. By establishing these security associations, IPsec ensures confidentiality, integrity, and authenticity of the data being transmitted between network nodes. Therefore, option C accurately describes how IPsec provides secure networking for applications within an organization.

6. Question 256 · 1334 in bank

   What is a characteristic of frame switching?

   • Apopulates the ARP table with the egress port
   • Bdrops received MAC addresses not listed in the address table
   • Cstores and forwards frames in a buffer and uses error checking
   • Drewrites the source and destination MAC address

   Show answer

   Answer: C

   Explanation

   Frame switching involves the process of storing and forwarding frames in a buffer. When a frame is received, it is stored in a buffer before being forwarded to the egress port. This method allows for error checking before forwarding the frame, ensuring more reliable transmission. Frame switching is commonly associated with Ethernet switching in networking.
