Question 1
Question
R1 and R2 attach to the same Ethernet VLAN, with subnet 10.1.19.0/25, with addresses 10.1.19.1 and 10.1.19.2, respectively, configured with the ip address interface subcommand. Host A refers to 10.1.19.1 as its default router, and host B refers to 10.1.19.2 as its default router. The routers do not use an FHRP. Which of the following are problems for this LAN?
Answer
-
The design breaks IPv4 addressing rules, because two routers cannot connect to the same LAN subnet.
-
If one router fails, neither host can send packets off-subnet.
-
If one router fails, both hosts will use the one remaining router as default router
-
If one router fails, the host that uses that router as a default router cannot send packets off-subnet .
Question 2
Question
R1 and R2 attach to the same Ethernet VLAN, with subnet 10.1.19.0/25, with addresses 10.1.19.1 and 10.1.19.2, respectively, configured with the ip address interface subcommand. The routers use an FHRP. Host A and host B attach to the same LAN and have correct default router settings per the FHRP configuration. Which of the following statements is true for this LAN?
Answer
-
The design breaks IPv4 addressing rules, because two routers cannot connect to the same LAN subnet.
-
If one router fails, neither host can send packets off-subnet.
-
If one router fails, both hosts will use the one remaining router as a default router.
-
If one router fails, only one of the two hosts will still be able to send packets off-subnet.
Question 3
Question
Which of the following FHRP options uses an active/active approach (per subnet) to
support first-hop (default router) traffic when implemented with two routers on the
same LAN?
Answer
-
GLBP
-
HSRP
-
BFD
-
VRRP
Question 4
Question
R1 and R2 attach to the same Ethernet VLAN, with subnet 10.1.19.0/25, with
addresses 10.1.19.1 and 10.1.19.2, respectively, configured with the ip addressinterface subcommand. The routers use HSRP. The network engineer prefers to have R1 be
the default router when both R1 and R2 are up. Which of the following is the likely
default router setting for hosts in this subnet?
Answer
-
10.1.19.1
-
10.1.19.2
-
Another IP address in subnet 10.1.19.0/25 other than 10.1.19.1 and 10.1.19.2
-
A hostname that the FHRP mini-DNS will initially point to 10.1.19.1
Question 5
Question
The following text lists output taken from router R3, which is using HSRP. Subnet
10.1.12.0 uses mask 255.255.255.0. Based on the output of this command, which of the following answers is true ?
R3# show standby brief
Interface____Grp___ Pri__P___State___Active___Standby___Virtual IP
Gi0/0_________1_____105_____Active___local____10.1.12.1__10.1.12.2
Answer
-
Hosts with a default router setting of 10.1.12.1 are sending their packets to router R3
-
Hosts with a default router setting of 10.1.12.2 are sending their packets to router R3
-
Router R3 has an ip address 10.1.12.2 255.255.255.0command confi gured on its G0/0 interface.
-
Router R3 has an ip address 10.1.12.1 255.255.255.0command configured on its G0/0 interface.
Question 6
Question
The following text lists output taken from router R3, which is using GLBP. Subnet
10.1.12.0 uses mask 255.255.255.0. Based on the output of this command, which of the
following answers is true?
R3# show glbp brief
Interface____Grp____Fwd____Pri___State_____Address___________Active router____Standby router
Gi0/0_________ 1______ -_____ 100 __Standby__10.1.12.2__________10.1.12.4_________ local
Gi0/0_________ 1______ 1______ -____ Active____ 0007.b400.0101__ local ______________-
Gi0/0_________ 1______ 2______ -____ Listen____ 0007.b400.0102 __10.1.12.4__________ -
Answer
-
R3 is the active virtual gateway.
-
The router with an interface IP address of 10.1.12.2, configured with the ip address command, is the active virtual gateway
-
The router with an interface IP address of 10.1.12.4, configured with the ip address command, is the active virtual gateway.
-
The output does not identify the active virtual gateway, because the AVG concept is a VRRP concept, not GLBP .
