1. Question 661 · 871 in bank

   Which of the following is used when a workstation sends a DHCP broadcast to a server on another LAN?

   • AReservation
   • BDynamic assignment
   • CHelper address
   • DDHCP offer

   Show answer

   Answer: C

   Explanation

   C. Helper address A DHCP helper address is configured on routers or switches to forward DHCP broadcast packets from clients on a different LAN to the DHCP server. This allows workstations on one subnet to communicate with a DHCP server on another subnet, which is necessary because DHCP broadcasts are not normally forwarded across network boundaries.

2. Question 662 · 871 in bank

   A network is experiencing a number of CRC errors during normal network communication. At which of the following layers of the OSI model will the administrator MOST likely start to troubleshoot?

   • ALayer 1
   • BLayer 2
   • CLayer 3
   • DLayer 4
   • ELayer 5
   • FLayer 6
   • GLayer 7

   Show answer

   Answer: B

   Explanation

   The data unit on Layer 2 is a frame. Each frame contains a frame header, body, and a frame trailer: Header: typically includes MAC addresses for the source and destination nodes. Body: consists of the bits being transmitted. Trailer: includes error detection information. When errors are detected, and depending on the implementation or configuration of a network or protocol, frames may be discarded or the error may be reported up to higher layers for further error correction. Examples of error detection mechanisms: Cyclic Redundancy Check (CRC) and Frame Check Sequence (FCS). Learn more about error detection techniques here. Answer is Layer 2 (B)

3. Question 663 · 871 in bank

   Branch users are experiencing issues with videoconferencing. Which of the following will the company MOST likely configure to improve performance for these applications?

   • ALink Aggregation Control Protocol
   • BDynamic routing
   • CQuality of service
   • DNetwork load balancer
   • EStatic IP addresses

   Show answer

   Answer: C

   Explanation

   Answer is C. To improve performance for videoconferencing applications for branch users, the company may consider configuring Quality of Service (QoS). QoS is a set of techniques used to manage network resources and prioritize traffic to ensure that critical applications, like videoconferencing, receive the necessary bandwidth and experience lower latency. By implementing QoS, the company can prioritize real-time traffic, such as video and voice, over less time-sensitive data, leading to a better user experience in videoconferencing sessions.

4. Question 664 · 871 in bank

   An administrator is adjusting the routing policy to ensure the headquarters location can connect to a new out-of-state branch office via BGP. Which of the following types of networks is being described?

   • APAN
   • BMAN
   • CLAN
   • DWAN

   Show answer

   Answer: D

   Explanation

   D. WAN The scenario describes a Wide Area Network (WAN), which connects multiple local area networks (LANs) across geographically dispersed locations, such as between a headquarters and a new out-of-state branch office. WANs typically use technologies like Border Gateway Protocol (BGP) to manage the exchange of routing and reachability information between large networks on the internet.

5. Question 665 · 871 in bank

   A company wants to implement a disaster recovery site for non-critical applications, which can tolerate a short period of downtime. Which of the following types of sites should the company implement to achieve this goal?

   • AHot
   • BCold
   • CWarm
   • DPassive

   Show answer

   Answer: C

   Explanation

   C. Warm A warm site is a type of disaster recovery site that offers a compromise between the instant availability of a hot site and the cost-effectiveness of a cold site. It is equipped with some hardware and connectivity, allowing for a quicker recovery than a cold site but not instantaneously as with a hot site. Warm sites are suitable for non-critical applications that can tolerate a short period of downtime, fitting the company's requirements described.

   • AAccess control vestibule
   • BCameras
   • CAsset tag
   • DMotion detectors

   Show answer

   Answer: B

   Explanation

   B. Cameras Cameras can be used to identify users after an action has occurred. They provide visual records of activities, allowing for post-event analysis and identification of individuals involved in specific incidents.

7. Question 667 · 871 in bank

   Which of the following standards would apply to a 10GB network link that is 1.86mi (3km)?

   • A10GBASE-TX
   • B10GBASE-T
   • C10GBASE-SR
   • D10GBASE-LR

   Show answer

   Answer: D

   Explanation

   D. 10GBASE-LR 10GBASE-LR is a standard for 10 Gigabit Ethernet over single-mode fiber that can support distances up to 10 kilometers, making it suitable for a network link that is 1.86 miles (approximately 3 kilometers) long. This standard is designed for long-range communication, which is required in the scenario provided.

   Which of the following kinds of targeted attacks uses multiple computers or bots to request the same resource repeatedly?

   • AOn-path
   • BDDoS
   • CARP spoofing
   • DMAC flooding

   Show answer

   Answer: B

   Explanation

   A DDoS makes the most sense because in a DDoS attack, the threat actor uses multiple computers that are infected to constantly make requests to a server which overwhelms it and causes network interruption.

9. Question 669 · 871 in bank

   A local service provider connected 20 schools in a large city with a fiber-optic switched network. Which of the following network types did the provider set up?

   • ALAN
   • BMAN
   • CCAN
   • DWAN

   Show answer

   Answer: B

   Explanation

   B. MAN (Metropolitan Area Network) When a local service provider connects multiple schools in a large city with a fiber-optic switched network, the network type set up is a Metropolitan Area Network (MAN). A MAN covers a larger geographical area than a Local Area Network (LAN) but is smaller in scale compared to a Wide Area Network (WAN). MANs are designed to connect entities within a metropolitan or city area.
