John has been hired to improve the local network of Company G. This implementation consists of a solution that allows two or more routers to be configured in a virtual group to share a virtual IP address. The routers in the virtual group cooperate with each other to present a single virtual IP address as the default gateway to hosts on the local network. One router is elected as the active router, responsible for sending packets to the virtual IP address, while the other routers in the group act as standby routers. To fulfill the implementation, John will use the following routing protocols: A- BGP (Border Gateway Protocol); B- OSPF (Open Shortest Path First); C- RIP (Routing Information Protocol); D- HSRP (Hot Standby Router Protocol); E- VRRP (Virtual Router Redundancy Protocol). To provide high network availability by providing first-hop redundancy for hosts on an IPv4 network, an Analyst has configured Hot Standby Router (HSRP) by enabling preemption only on the router with the highest HSRP priority. By enabling preemption on this router, it will be elected as the backup router in case the active router is unavailable. it will be elected as the standby router. it will not be elected as the active router. it will be forced into a new HSRP election process in case of a reboot or failure. the lowest IP address configured on its physical interface will be used as the virtual IP (VIP). Consider the HSRP and VRRP protocols and their correct and respective characteristics. It is correct to state that obs.: The main difference between VRRP and HSRP is that VRRP is an open standard protocol, while HSRP is Cisco proprietary. HSRP must use a separate virtual IP as the shared IP address. VRRP on the other hand, can use one of the router's physical IPs as the shared IP. By default, HSRP uses a 3-second hello timer, while VRRP uses a 1-second advertisement interval. Roles Names HSRP uses active and standby roles VRRP uses master and backup roles a- In HSRP, instead of having the roles “active” and “standby”, we use “master” and “backup”. B- HSRP is vendor-independent, while VRRP is Cisco proprietary. c- HSRP uses only four states for the routers that are part of the group. The protocol defines what actions they will be able to perform. D- In VRRP, the VRRP group IP address (the VIP) is the IP address of one of the routers. In HSRP, the HSRP group VIP address is a unique address. e- One of the states that VRRP can assume is the Speak State. In this state, the router forwards hello messages and effectively participates in router election. Regarding the different types of redundant gateway protocols, it is INCORRECT to state that: A- The CARP, HSRP, HSRP and GLBP protocols are examples of redundant gateway protocols, which manage the same virtual gateway IP address, distributed among a group of network devices with different real IP addresses. B- VRRP is a non-proprietary protocol, defined in RFC 3768, which allows real and virtual addresses to effectively participate in the redundancy mechanism. C- The Virtual Router Redundancy Protocol (VRRP) and Gateway Load Balancing Protocol (GLBP) protocols can assign different Media Access Control (MAC) addresses to the same virtual IP address, thus ensuring gateway redundancy and load balancing. D- GLBP contains two types of active gateways, the Active Virtual Gateway (AVG) and the Active Virtual Forwarder (AVF), so that the AVG is the main gateway of the group, while the AVFs are the backups. E- The messages exchanged between routers belonging to the same VRRP group are called Link-State Advertisements (LSA), via the IPv4 multicast address 224.0.0.18. Fault tolerance technology is considered a requirement in mission-critical systems. Redundancy is an important technique in this context, occurring at various levels, from communication involving cabling to the replication of servers and network assets. Duplication of gateways is also an example of the use of redundancy. Regarding redundant gateway protocols, it is INCORRECT to state that hint: HSRP uses a virtual MAC and IP address for the two routers to represent with hosts as a single default gateway. A- Redundant gateway protocols arose from the need to keep a network always operational, using replicated equipment so that when a failure occurs in the communication of the main link, the replacement takes its place, not leaving the network unavailable, bringing high availability to it. B- Protocols called CARP (Common Address Redundancy Protocol) and HSRP (Hot Standby Router Protocol) allow sharing the same IP address between multiple hosts, in addition to enabling the configuration of load balancing. C- HSRP, VRRP and GLBP are examples of gateway protocols that manage the same virtual gateway IP, distributed among a group of routers with different real IP addresses. D- HSRP, VRRP and GLBP protocols can assign different MAC addresses to the same Virtual IP. One solution to improve network availability and eliminate the single point of failure inherent in the static routed environment by default is VRRP (Virtual Router Redundance Protocol), characterized by: A- executing all messages using IPv4 or IPv6 multicast datagram. B- preventing the association of a virtual router with its real address on an interface. C- presenting restrictions with a different address mapping on different LANs. D- requiring at least one master router and two backup routers, for better traffic flow. The Information Technology team of a Court wants to improve the availability of its internal network, so it is researching redundancy solutions for its connectivity devices. One of the solutions investigated uses VRRP (Virtual Router Redundancy Protocol) to eliminate the single point of failure inherent in the static routed environment by default. A characteristic that is also inherent to the solution investigated is that: A- all messages are executed using IPv4 or IPv6 multicast datagram; B- a VRRP router cannot associate a virtual router with its real address on an interface; C- there is a restriction against reusing the same VRID with a different address mapping on different LANs; D- for its operation to be possible, there must be at least one Master router and two Backup routers; E- if the Master router becomes unavailable, the Backup router with the lowest priority will be elected Master and will perform traffic flow. Indicate the correct statement regarding a local network with IPv4 protocol and configured with a VRRP group with its respective protocol in version 3. a-It is not possible to configure a local network with a VRRP group using proxy-arp. B- The VRID corresponds to a multicast address that must be configured as the default router on the network workstations. C- The interfaces of the routers that are part of a VRRP group must have the same IPv4 address, with packets forwarded only by the master router. D- ARP requests, related to the address of the default router, are responded to with a specific MAC address, different from the MAC addresses of the router interfaces. E- In a local network, there must be only one master router and only one VRID, in order to avoid routing loops. Select the incorrect alternative regarding the configuration of Switches: A= With the Gateway function also assigned to Switches for Routing between VLANs, the VRRP protocol has become an important tool for the redundancy of Switches that act as Gateways for VLANs, maintaining packet routing even in the event of failures in one of the Switches. B- “Clustering” techniques, also known as “Stacking” of Switches with the XRN, IRF and IRF version 2 protocols, are also used as alternatives to facilitate the administration and stability of the LAN, with the “slave” Switch assuming the main function in the event of a “master” failure. C- The messages exchanged between computers for dynamic discovery of hosts with an IPv4 address for communication have Broadcast behavior. The Switch, upon receiving a Broadcast message, forwards the information to all ports, including the port that received the initial message. D- For hosts with IPv6 addresses, messages for neighbor and router discovery are in Multicast addresses, but the initial behavior of the message is very similar (for a Switch) to a Broadcast message. Consider a local network scenario where two routers form a VRRP-v3 group in order to increase routing availability. When a workstation (host) makes an ARP request for the IPv4 address of the configured default gateway, the response to this request contains hint: When a workstation sends an ARP request for the IP address of the default gateway (which is the virtual IP address assigned to the VRRP group), the Active (Master) router responds. Instead of responding with the MAC address of its own physical interface, the Master router responds with a special Virtual Router MAC Address. Virtual Router MAC Address: The format for the Virtual Router MAC Address in VRRP for IPv4 is: 00:00:5E:00:01:VRID 00:00:5E:00:01:VRID where: 00:00:5E:00:01 is the fixed portion assigned by IANA for VRRP. VRID (Virtual Router Identifier) is the unique identifier for the VRRP group and is placed in the last byte. A- the list of MAC addresses of the interfaces of the routers that form the VRRP group. B- the MAC address of the primary router's interface, with an additional parameter containing the VRID of the group. C- the specific multicast MAC address corresponding to all routers running the VRRP protocol. D- the special Virtual_Router_MAC_Address address that contains the VRID of the group. E- the specific multicast MAC address corresponding to all routers running the VRRP protocol, placing the VRID in the last byte of the address.
