If a router cannot determine the next hop for a packet, the router will:
- A.
Forward the packet to the default route.
- B.
Send the packet back to the packet's source.
- C.
Broadcast the packet.
- D.
Store the packet in the memory buffer.
Correct Answer
A. Forward the packet to the default route.Explanation
When a router cannot determine the next hop for a packet, it means that it does not have a specific route in its routing table for that packet's destination. In this case, the router will forward the packet to the default route. The default route is a pre-configured route that the router uses when it doesn't have a specific route for a destination. By forwarding the packet to the default route, the router ensures that the packet is not dropped and has a chance to reach its intended destination.Rate this question:

The protocol that maps IP addresses to a Media Access Control (MAC) address is:
- A.
Internet Message Access Protocol (IMAP).
- B.
Dynamic Host Configuration Protocol (DHCP).
- C.
Routing Information Protocol (RIP).
- D.
User Datagram Protocol (UDP).
- E.
Address Resolution Protocol (ARP).
Correct Answer
E. Address Resolution Protocol (ARP).Explanation
ARP is the protocol that maps IP addresses to MAC addresses. It is used to find the MAC address of a device on the same network when only its IP address is known. By sending an ARP request, the device can obtain the MAC address from the ARP table or by broadcasting the request to all devices on the network. Once the MAC address is obtained, it can be used to establish a direct communication link between devices. IMAP, DHCP, RIP, and UDP are all different protocols used for other purposes in computer networks.Rate this question:

Verify that the DHCP service is available.
Correct Answer
D. Verify that the DHCP service is available.Explanation
The correct answer is to verify that the DHCP service is available. The IP address 169.254.48.97 is an Automatic Private IP Address (APIPA) which is assigned when a device is unable to obtain an IP address from a DHCP server. This suggests that the user's computer is not receiving a valid IP address from the DHCP server. By verifying the availability of the DHCP service, any issues with the server can be identified and resolved, allowing the user to obtain a valid IP address and restore access to network resources.Rate this question:

Which protocol can be used to encrypt packets on the Internet?
- A.
SNMP
- B.
HTTPS
- C.
TFTP
- D.
HTTP
Correct Answer
B. HTTPSExplanation
HTTPS (Hypertext Transfer Protocol Secure) is the correct answer because it is a protocol that provides secure communication over a computer network. It uses encryption to protect the data transmitted between a web browser and a website, ensuring that the packets cannot be intercepted or tampered with by unauthorized parties. This is particularly important for sensitive information such as passwords, credit card numbers, and personal data, as it prevents potential attackers from accessing or manipulating the data while it is in transit.Rate this question:

Internet Key Exchange (IKE) is responsible for which two functions? (Choose two.)
- A.
Establishing network speed parameters
- B.
Verifying the client's patch level
- C.
Negotiating algorithms to use
- D.
Exchanging key information
Correct Answer(s)
A. Establishing network speed parameters
B. Verifying the client's patch levelExplanation
IKE, or Internet Key Exchange, is a protocol used for establishing secure communication channels in IPsec VPNs. It is responsible for negotiating and establishing the security parameters and algorithms to be used for encryption and authentication. It also facilitates the exchange of key information between the communicating parties. However, IKE is not responsible for establishing network speed parameters or verifying the client's patch level. These functions are typically handled by other protocols or mechanisms.Rate this question:

What happens when an 802.11a node broadcasts within the range of an 802.11g access point?
- A.
The access point transmits, but the node is unable to receive.
- B.
A connection occurs.
- C.
Both the node and the access point are unable to transmit.
- D.
The node transmits, but the access point is unable to receive.
Correct Answer
C. Both the node and the access point are unable to transmit.Explanation
When an 802.11a node broadcasts within the range of an 802.11g access point, both the node and the access point are unable to transmit. This is because 802.11a and 802.11g operate on different frequency bands and are not compatible with each other. The 802.11g access point will not be able to understand the signals sent by the 802.11a node, and vice versa. As a result, both the node and the access point will be unable to establish a connection and transmit data.Rate this question:
