When configuring a static route, certain parameters are required for the route to function correctly. Let us analyze each option:

Option A :

Incorrect : The preference (or administrative distance) is optional. If not specified, the router uses the default preference value for static routes.

Option B :

Incorrect : While the next-hop IP address is commonly used in static route configuration, it is not always mandatory. For example, you can specify an outgoing interface instead of a next-hop address.

Option C :

Incorrect : The subnet mask is essential for defining the network prefix of the destination network. Without the mask, the router cannot determine the range of IP addresses covered by the route.

Option D :

Correct : The subnet mask is mandatory when configuring a static route. It defines the network portion of the destination IP address, enabling the router to match packets to the correct route.

Thus, the correct answer is D .

IP Routing and Subnet Masks by Huawei.

An OLT (Optical Line Terminal) is a key component in fiber-optic access networks, particularly in GPON and XGS-PON systems. It serves multiple roles:

Switch or Router Role :

The OLT acts as a Layer 2/Layer 3 switch or router, aggregating traffic from multiple ONUs (Optical Network Units) and forwarding it to the core network.

Multi-Service Provisioning Platform :

The OLT supports multiple services, including Internet access (data), voice (VoIP), and video (IPTV). It integrates these services over a single fiber infrastructure, making it a versatile platform for service providers.

Why TRUE?

The statement accurately describes the OLT's functionality as both a switch/router and a multi-service provisioning platform.

Thus, the correct answer is A .

Firewall Settings (Option A) :

Incorrect firewall settings on the PC can block outbound HTTP/HTTPS traffic, preventing access to web pages.

Browser Settings (Option B) :

Misconfigured browser settings (e.g., proxy settings in Internet Explorer) can prevent the browser from connecting to websites.

Upper-Layer Device Configuration (Option C) :

Incorrect configurations on upper-layer devices (e.g., NAT, routing, or DNS settings) can prevent proper communication between the user and external networks.

Website Server Fault (Option D) :

If the issue affects all web pages , it is unlikely to be caused by a single website server being faulty. This option is irrelevant in this scenario.

Why A, B, C?

These options directly address potential issues that could prevent access to all web pages after successful authentication.

Thus, the correct answers are A, B, C .

PPP Protocol Overview :

PPP (Point-to-Point Protocol) uses the PROTOCOL field in its header to identify the type of encapsulated protocol.

Protocol Field Values :

0x8021 : Indicates IPCP (Internet Protocol Control Protocol) , which is used to negotiate IP-related parameters during PPP session establishment.

0xC021 : Indicates LCP (Link Control Protocol) , which is used for establishing, configuring, and testing the PPP link.

0x002B : Indicates IPX (Internetwork Packet Exchange) .

0x0021 : Indicates IP (Internet Protocol) .

Why A?

The value 0x8021 corresponds to IPCP , making it the correct answer.

Thus, the correct answer is A .
