Consider the following two statements. S1 : Destination MAC address of an ARP reply is a broadcast address. S2 : Destination MAC address of an ARP request is a broadcast address. Which one of the following choices is correct?

Consider the following two statements. S1 : Destination MAC address of an ARP reply is a broadcast address. S2 : Destination MAC address of an ARP request is a broadcast address. Which one of the following choices is correct? Correct Answer S<sub>1</sub> is false and S<sub>2</sub> is true.

Answer: Option 3

Concept:

Address Resolution Protocol:

  • ARP resolves an IP address to a MAC address.
  • The purpose of the ARP request packet is to query all the other hosts and routers on the subnet to determine the MAC address corresponding to the IP address that is being resolved.
  • The ARP Request Packet, broadcast to all other hosts and routers on the subnet using MAC broadcast address, namely, FF-FF-FF-FF-FF-FF.
  • The ARP reply will be a unicast packet that contains the desired mapping. 

Explanation:

Statement 1:Destination MAC address of an ARP reply is a broadcast address.

This is not correct as the Destination MAC address of ARP reply will be a unicast address as ARP reply will be a unicast packet.

Statement 2: Destination MAC address of an ARP request is a broadcast address.

This is correct.

Consider the three-way handshake mechanism followed during TCP connection establishment between hosts P and Q. Let X and Y be two random 32-bit starting sequence numbers chosen by P and Q respectively. Suppose P sends a TCP connection request message to Q with a TCP segment having SYN bit = 1, SEQ number = X, and ACK bit = 0. Suppose Q accepts the connection request. Which one of the following choices represents the information present in the TCP segment header that is sent by Q to P?

Consider the following policies for preventing deadlock in a system with mutually exclusive resources. I. Processes should acquire all their resources at the beginning of execution. If any resource is not available, all resources acquired so far are released II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger than its currently held resources Which of the above policies can be used for preventing deadlock?
