A(n) ____________________ serves as a channel through which several clients can exchange data with the same server or different servers.

While analyzing the contents of the IP routing table in a router, the administrator notices the following routes in the table: PrefixNextHop IPInterface 192.168.1.0 /24172.16.31.1 Ethernet0 192.168.2.0 /24172.16.31.1 Ethernet0 172.16.31.0 /24 Directly Connected Ethernet0 0.0.0.0/0172.16.31.2 Ethernet0 Which of the following BEST describes what would occur if a packet from 192.168.1.4 were sent to 192.168.3.4?

A. The packet will be dropped as there is no matching route in the IP routing table to reach the destination network B. An ICMP network unreachable message will be sent to 192.168.1.4 C. The packet will be forwarded to 172.16.31.2 D. The packet will be forwarded to 172.16.31.1 since the source IP address is in the 192.168.1.0/24 range

Consider the following class definitions:class bClass{public:void setX(int a);//Postcondition: x = a;void print() const;private:int x;};class dClass: public bClass{public:void setXY(int a, int b);//Postcondition: x = a; y = b;void print() const;private:int y;};Which of the following correctly sets the values of x and y?

A. void dClass::setXY(int a, int b) { bClass::setX(a); y = b; } B. void dClass::setXY(int a, int b) { x = a; y = b; } C. void dClass::setXY(int a, int b) { x = bClass::setX(a); y = bClass::setY(b); } D. void dClass::setXY(int a, int b) { x = bClass.setX(a); b = y; }
