   What are network endpoints?

   • Asupport inter-VLAN connectivity
   • Ba threat to the network if they are compromised
   • Cact as routers to connect a user to the service provider network

   Show answer

   Answer: B

   Explanation

   A. support inter-VLAN connectivity A Layer 3 switch’s job. And an L3 switch is an intermediary device. Wrong answer. B. a threat to the network if they are compromised Your PC is an end device. Another user retrieves your username and your password, and has unauthorized access to your computer. What could happen to your network? Correct answer. C. act as routers to connect a user to the service provider network A router is an intermediary device. Wrong answer. D. enforce policies for campus-wide traffic going to the Internet A firewall’s job. And a firewall is an intermediary device. Wrong answer.

2. Question 1252 · 1334 in bank

   What is a similarity between global and unique local IPv6 addresses?

   • AThey use the same process for subnetting.
   • BThey are part of the multicast IPv6 group type.
   • CThey are routable on the global internet.
   • DThey are allocated by the same organization.

   Show answer

   Answer: A

   Explanation

   Unique local addresses are NOT assigned by an organization. https://en.wikipedia.org/wiki/Unique_local_address A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00::/7.[1] Its purpose in IPv6 is somewhat analogous to IPv4 private network addressing, but with significant differences. Unique local addresses may be used freely, without centralized registration, inside a single site or organization or spanning a limited number of sites or organizations. They are routable only within the scope of such private networks, but not in the global IPv6 Internet.

   An engineer must configure the IPv6 address 2001:0db8:0000:0000:0700:0003:400F:572B on the serial0/0 interface of the HQ router and wants to compress it for easier configuration. Which command must be issued on the router interface?

   • Aipv6 address 2001:db8::700:3:400F:572B
   • Bipv6 address 2001:db8:0::700:3:4F:572B
   • Cipv6 address 2001::db8:0000::700:3:400F:572B

4. Question 1254 · 1334 in bank

   

   Refer to the exhibit. A packet that is sourced from 172.16.3.254 is destined for the IP address of GigabitEthernet0/0/0. What is the subnet mask of the destination route?

   • A0.0.0.0
   • B255.255.254.0
   • C255.255.255.0
   • D255.255.255.255

   Show answer

   Answer: D

   Explanation

   This help me clear this up: A connected route represents the network address. It uses the actual subnet prefix (mask). A local route represents the host address. It always uses the subnet prefix /32.Dec 20, 2021 Connected Routes and Local Routes Explained ComputerNetworkingNotes https://www.computernetworkingnotes.com › connected-. Connected = Network Address Local = Address of the interface So the questing is what is the interface subnet mask?

5. Question 1255 · 1334 in bank

   

   Refer to the exhibit. The iPv6 address for the LAN segment on router R2 must be configured using the EUI-64 format. Which address must be used?

   • Aipv6 address 2001:DB8:D8D2:1009:10A0:ABFF:FECC:1 eui-64
   • Bipv6 address 2001:DB8:D8D2:1009:1230:ABFF:FECC:1 eui-64

   • Dipv6 address 2001:DB8:D8D2:1009:12A0:AB34:FFCC:1 eui-64

   Show answer

   Answer: A

   Explanation

   Option ‘a’ is correct. Prefix:2001:DB8:D8D2:1009::/64. Interface MAC: 12:A0:AB:CC:00:01 Split MAC in half: 12:A0:AB – CC:00:01 Add FFFE shim: 12:A0:AB:FF:FE:CC:00:01 Toggle bit 7: - First 8 bits = 12 = [0001][0010] - Invert 7th bit: [0001][0000] = 10 New bottom 64-bit address: 10:A0:AB:FF:FE:CC:00:01 Change Format: 10A0:ABFF:FECC:0001 Add top 64-bits: 2001:DB8:D8D2:1009:10A0:ABFF:FECC:0001 Condense: 2001:DB8:D8D2:1009:10A0:ABFF:FECC:1 Full Interface Command: ipv6 address 2001:DB8:D8D2:1009:10A0:ABFF:FECC:1 eui-64

6. Question 1256 · 1334 in bank

   

   Refer to the exhibit. According to the output, which parameter set is validated using the routing table of R7?

   • AR7 is missing a gateway of last resort. R7 is receiving routes that were redistributed in EIGRP. R7 will forward traffic destined to 10.90.8.0/24.
   • BR7 has a gateway of last resort available. R7 is receiving routes that were redistributed from BGP. R7 will drop traffic destined to 10.90.8.0/24.
   • CR7 is missing a gateway of last resort. R7 is receiving routes that were redistributed from BGP. R7 will forward traffic destined to 10.90.8.0/24.
   • DR7 has a gateway of last resort available. R7 is receiving routes that were redistributed in EIGRP. R7 will drop traffic destined to 10.90.8.0/24.

   Show answer

   Answer: D

   Explanation

   I think D is the best answer, however, I don't think the router would drop packets to 10.90.8.0/24, it would just send the packets out the gateway of last resort. Correct me if I am wrong please.

8. Question 1258 · 1334 in bank

   Select 2

   What are two purposes of HSRP? (Choose two.)

   • AIt provides a mechanism for diskless clients to autoconfigure their IP parameters during boot.
   • BIt improves network availability by providing redundant gateways.
   • CIt groups two or more routers to operate as one virtual router.
   • DIt passes configuration information to hosts in a TCP/IP network.
   • EIt helps hosts on the network to reach remote subnets without a default gateway.

   Show answer

   Answer: BC

   Explanation

   B & C are correct B. HSRP provides redundancy by allowing multiple routers to work together in a group, ensuring that if one router fails, another can take over its role seamlessly. This enhances network availability and reliability. C. HSRP allows multiple routers to form a virtual router group, with one router acting as the active router and the others as standby routers. This virtual router group presents a single virtual IP address and MAC address to hosts on the LAN, providing redundancy and ensuring uninterrupted connectivity even if the active router fails.
