A critical infrastructure switch is identified as end-of-support. Which of the following is the best next step to ensure security?
Answer: B
B. Decommission and replace the switch. Explanation: An end-of-support (EOS) device no longer receives security updates, patches, or vendor support. This makes it vulnerable to exploits and security risks, as there will be no fixes for known vulnerabilities. The most effective and secure approach in this situation is to decommission and replace the outdated switch with a supported model that will continue to receive security updates and patches.

A company's marketing team created a new application and would like to create a DNS record for newapplication.comptia.org that always resolves to the same address as wwww.comptia.org. Which of the following records should the administrator use?
Answer: C
C. CNAME. A Canonical Name (CNAME) (or alias) record is used to configure an alias for an existing address record (A or AAAA). For example, the IP address of a web server with the host record lamp could also be resolved by the alias www. CNAME records are also often used to make DNS administration easier. For example, an alias can be redirected to a completely different host temporarily during system maintenance.

Which of the following routing protocols uses an autonomous system number?
Answer: C
C. BGP. According to CompTIA: "Autonomous system numbers (ASN) are allocated to ISPs by IANA via the various regional registries. BGP is a type of exterior gateway protocol (in fact, it replaced a protocol named EGP) for communications between routers in separate autonomous systems. When BGP is used within an AS, it is referred to as Interior BGP (IBGP), and when implemented between autonomous systems, it is referred to as Exterior BGP (EBGP)."
