Which of the following are benefits of a Link-State routing protocol?

  1. Reduces convergence time

  2. Allows for a larger scalable network

  3. Allows for a larger scalable network

  4. Allows the use of a more robust addressing scheme

  5. all of the above


Correct Option: E

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Reduces convergence time - This option is correct. Link-State routing protocols, such as OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System), use the shortest path first algorithm to calculate the best path for each destination. This allows for faster convergence, meaning that the network can quickly adapt to changes in the topology.

Option B) Allows for a larger scalable network - This option is correct. Link-State routing protocols can scale well in large networks. They maintain a detailed map of the network topology, which allows for efficient path calculation and scalability.

Option C) Allows for a larger scalable network - This option is correct. This is a duplicate of option B.

Option D) Allows the use of a more robust addressing scheme - This option is correct. Link-State routing protocols support the use of hierarchical addressing schemes, such as Classless Inter-Domain Routing (CIDR), which allows for efficient allocation and utilization of IP addresses.

Based on the explanations above, the correct answer is E) all of the above. All of the options listed are benefits of a Link-State routing protocol.

  1. ARP is used to map Ring numbers to IP addresses

  2. ARP is used to map Ring numbers to MAC addresses of the hosts on that ring

  3. ARP is used to map a MAC address to an IP address

  4. ARP is used to map an IP address to a MAC address


Correct Option: D

How many subnets are possible with a Class B address and a subnet mask of 255.255.255.128?

  1. 255

  2. 256

  3. 254

  4. 512

  5. 510


Correct Option: E

Where is the running configuration file of the router stored?

  1. in NVRAM

  2. in ROM

  3. in RAM

  4. in Flash Memory

  5. In ROM or RAM


Correct Option: C

Which of the following switching methods accept only the first 6 bytes of a frame?

  1. store and forward

  2. cut-through

  3. tag

  4. fast frag


Correct Option: B
  1. All passwords can be encrypted

  2. A password can be set before a user can enter the privileged mode

  3. A password can be set for individual lines

  4. TACACS or Radius password authentication can be used.

  5. all of the above


Correct Option: E

The IPX is a universal standard for inter-LAN communication.

  1. True

  2. False


Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of the IPX protocol and inter-LAN communication.

The IPX (Internetwork Packet Exchange) protocol is a network layer protocol used in Novell NetWare networks. It is not a universal standard for inter-LAN communication. Instead, it is specific to Novell NetWare networks and is used for communication between devices within the same LAN (Local Area Network).

Therefore, the correct answer is B) False. The IPX is not a universal standard for inter-LAN communication.

Segmentation of a data stream happens at which layer of the OSI model?

  1. Data Link

  2. Physical

  3. Transport

  4. Netwrok


Correct Option: C
  1. Logical Link Control Layer

  2. Transport Layer

  3. Ethernet

  4. Data Link Layer

  5. Netwrok Layer


Correct Option: D
  1. For a window size of 3 the ack4 signal says send the 4th packet.

  2. For a window size of three, the packets will be sent in three different routes and acknowledgment is expected for each.

  3. For a window size of 3 the acknowledgement is always ack3 to notify THAT the 3 packets were received.

  4. None of the above.


Correct Option: A
  1. PVC

  2. LCI

  3. DLCI

  4. ASIC


Correct Option: C
Explanation:

To solve this question, the user needs to have a basic understanding of computer networking and the different components that make up a network. Specifically, the user should be familiar with Ethernet and Frame Relay, as well as the acronyms associated with these technologies.

Explanation of each option:

A. PVC: PVC stands for Permanent Virtual Circuit, which is a type of connection used in Frame Relay networks. This option is correct because PVC is the equivalent of MAC in Ethernet. Both PVC and MAC provide a unique identifier for each device on the network.

B. LCI: LCI stands for Link Connection Identifier, which is a term used in ATM (Asynchronous Transfer Mode) networks. This option is incorrect because it is not related to Frame Relay.

C. DLCI: DLCI stands for Data Link Connection Identifier, which is a term used in Frame Relay networks. This option is correct because DLCI is the equivalent of MAC in Ethernet. Both DLCI and MAC provide a unique identifier for each device on the network.

D. ASIC: ASIC stands for Application-Specific Integrated Circuit, which is a type of integrated circuit designed for a specific application. This option is incorrect because it is not related to either Ethernet or Frame Relay.

Therefore, the correct answer is:

The Answer is: C. DLCI

  1. A channel service unit/digital service unit (CSU/DSU)

  2. An Ethernet card

  3. DTE

  4. None of the above.


Correct Option: A

Which is a device used to connect ISDN Basic Rate Interface (BRI) connections to other interfaces, such as EIA/TIA-232 on a router?

  1. RJ-11 cable

  2. Cat 5

  3. ISDN terminal adapter

  4. ISDN power adapter


Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of ISDN Basic Rate Interface (BRI) connections and how they can be connected to other interfaces on a router.

Option A) RJ-11 cable - This option is incorrect because an RJ-11 cable is typically used for connecting telephones or modems to a telephone line, not for connecting ISDN BRI connections to other interfaces on a router.

Option B) Cat 5 - This option is incorrect because Cat 5 cables are commonly used for Ethernet connections, not for connecting ISDN BRI connections to other interfaces on a router.

Option C) ISDN terminal adapter - This option is correct. An ISDN terminal adapter is a device used to connect ISDN BRI connections to other interfaces, such as EIA/TIA-232, on a router. It acts as an intermediary between the ISDN network and the router, converting the BRI signals to a format that the router can understand.

Option D) ISDN power adapter - This option is incorrect because an ISDN power adapter is used to provide power to an ISDN device, such as an ISDN terminal adapter, but it does not directly connect ISDN BRI connections to other interfaces on a router.

The correct answer is C) ISDN terminal adapter. This option is correct because an ISDN terminal adapter is specifically designed to connect ISDN BRI connections to other interfaces on a router.

The section of the carrier's network that is shared is often referred to as a WAN.

  1. True

  2. False


Correct Option: B
  1. Address Resolution Protocol (ARP)

  2. Relative Address Resolution Protocol (RARP)
