At which layer of the OSI model are routing protocols defined?
Routing protocols are defined at the network layer (Layer 3) of the OSI model. The network layer is responsible for routing packets across different networks using logical addresses (IP addresses). Routing protocols are used to exchange routing information between routers and to determine the best path for data delivery. Some examples of routing protocols are BGP, OSPF, RIP, and EIGRP. Palo Alto Networks devices support advanced routing features using the Advanced Routing Engine1.

Which of these ports is normally associated with HTTPS?
HTTPS is a protocol that encrypts and secures the communication between web browsers and servers. HTTPS uses SSL or TLS certificates to establish a secure connection and prevent unauthorized access or tampering of data. HTTPS typically uses port 443, which is the default port for HTTPS connections. Port 443 is different from port 80, which is the default port for HTTP connections. HTTP is an unencrypted and insecure protocol that can expose sensitive information or allow malicious attacks. Port 443 is also different from port 5050, which is a common port for some applications or services, such as Yahoo Messenger or SIP. Port 5050 is not associated with HTTPS and does not provide any encryption or security. Port 443 is also different from port 25, which is the default port for SMTP, the protocol used for sending and receiving emails. Port 25 is not associated with HTTPS and does not encrypt the email content or headers. Reference:

Which of the following is a Routed Protocol?
A routed protocol is a protocol by which data can be routed. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another network. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX). IP is the most widely used routed protocol on the Internet and other networks. It assigns a unique logical address to each device and enables data to be fragmented, reassembled, and routed across multiple networks.Reference:

What are two disadvantages of Static Rout ng? (Choose two.)
Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from dynamic routing traffic 1. Static routing has some advantages, such as simplicity, low overhead, and full control, but it also has some disadvantages, such as:
* Manual reconfiguration: Static routes require manual effort to configure and maintain. This can be time-consuming and error-prone, especially in large networks with many routes. If there is a change in the network topology or a link failure, the static routes need to be updated manually by the network administrator 23.
* Single point of failure: Static routing is not fault tolerant. This means that if the path used by the static route stops working, the traffic will not be rerouted automatically. The network will be unreachable until the failure is repaired or the static route is changed manually. Dynamic routing, on the other hand, can adapt to network changes and find alternative paths 23.
